Why does Ben Greenfield use NatureCBD every day?

“I take one to two capsules of this potent blend any point during the day when I need to lower inflammation from exercise, to decrease stress and anxiety, and to help me to have more creative focus for writing – and I use them again at night to cause me to fall asleep much, much faster and get refreshing, deep sleep that lasts the entire night.”

What is CBD?

Your endocannabinoid system (ECS) regulates everything from relaxation, to eating, sleeping, inflammation and even cognitive function. In a nutshell, your ECS is responsible for making sure your entire body is working optimally. There are two types of cannabinoid receptors found throughout your body (CB1 and CB2), but they are most abundant in your brain and immune system.

CBD is an abbreviation for cannabidiol, a prominent naturally-occurring cannabinoid component found in cannabis that comprises up to 40% of the plant and helps to regulate your ECS. After THC (Δ9-tetrahydrocannabinol) – which is the psychoactive component of cannabis most often associated with marijuana – CBD is by far the most studied natural cannabinoid, especially when it comes to medical benefits and addressing issues such as insomnia and anxiety. According to many researchers, CBD may be the single most important cannabinoid ever discovered.

Despite popular perceptions of marijuana, cannabidiol is a cannabinoid devoid of any type of strange psychoactive effect, although it can help with cognitive performance, memory, focus, etc. In other words, unlike THC, CBD won’t get you “high” and can actually help to counteract any unpleasant psychoactive effects of THC, taking any paranoia edge off of marijuana.

Why is NatureCBD Special?

Most CBD oil, capsules, powders, etc. are not easily absorbed by your body. They can spoil and become contaminated. They smell bad. They often taste bad too. And they’re not water soluble. Your body is composed of over 60% water, so what good is a product that cannot dissolve in water? This is why most CBD hemp oil products have an extremely poor bioavailability and you simply don’t experience or feel any of the effects of the CBD.

Using a process called “hybrid-nanoengineering” it is actually possible to get a highly bioavailable and absorbable form of CBD. The way that hybrid-nanoengineering works is that the cannabinoids and terpenoids are extracted from the hemp plant, combined with an Ayurvedic herbal blend and then processed into nanoparticle size.  Nanoparticles (1/100 the width of a human hair) are easier for your body to absorb and transport to where they are needed within your body. This means that a hybrid-nanoengineered CBD is over 10x more bioavailable in the body than any other oil based CBD, CBD tincture or CBD capsule, and that just 10mg of a nanoparticle CBD is comparable to 100mg of standard CBD.

The result of hybrid-nanoengineering with the Ayurvedic herbal blend is a raw oil that is high in CBD, virtually free of THC (less than 0.1%,) and complete with a full spectrum of other cannabinoids and terpenes, which work synergistically to make CBD even more effective. The oil is then encapsulated, and the result is an extremely absorbable CBD product, along with all the benefits of curcumin, lemon balm and Ashwagandha. The video above demonstrates the absorption difference between water soluble CBD that’s been hybrid-nanoengineered, compared to regular, non-water soluble CBD.

Nature CBD Ingredients

The hemp used to make NatureCBD is extracted from a special variety of sustainably raised, organic hemp that is specifically bred to contain naturally high concentrations of CBD, while still containing all of the natural cannabinoids, terpenoids, and other compounds of the original plant. The resulting oil then is strictly tested for purity and is free from pesticides and heavy metals.

And just to enhance the peaceful, calm, focus that NatureCBD gives you, we’ve also added to this unique custom formulation two big de-stressing and focus enhancing agents…

Scientific studies support the Indian herb ashwagandha’s ability not only to relieve stress, but also to protect brain cells against the deleterious effects of our modern lifestyles. For example, in validated models of anxiety and depression, ashwagandha has been demonstrated to be as effective as some tranquilizers and antidepressant drugs. Specifically, oral administration of ashwagandha for five days showed anxiety-relieving effects similar to those achieved by the anti-anxiety drug lorazepam (Ativan®), and antidepressant effects similar to those of the prescription antidepressant drug imipramine (Tofranil®).

Stress can cause increased peroxidation of lipids, while decreasing levels of the antioxidant enzymes catalase and glutathione peroxidase. When ashwagandha extract was administered by researchers one hour before a daily stress-inducing procedure, all of the parameters of free radical damage normalized in a dose-dependent manner.

Premature aging associated with chronic nervous tension is also related to increased oxidative stress, For example, in a remarkable animal study, examination of the brains of sacrificed animals showed that 85% of the brain cells observed in the animals exposed to chronic stress showed signs of degeneration. It is this type of cellular degeneration that can lead to long-term cognitive difficulties. Amazingly, when ashwagandha was administered to chronically stressed animals, the number of degenerating brain cells was reduced by 80%.

In one of the most complete human clinical trials to date, researchers studied the effects of a standardized extract of ashwagandha on the negative effects of stress, including elevated levels of the stress hormone cortisol. The results were impressive, with participants showing increased energy, reduced fatigue, better sleep, and an enhanced sense of well-being…

…along with a reduction of cortisol levels up to 26%!

Using a validated model of damaged nerve cells and impaired nerve-signaling pathways, researchers have that demonstrated that ashwagandha supports significant regeneration of the axons and dendrites of nerve cells along with the reconstruction of synapses, the junctions where nerve cells communicate with other cells. This means ashwagandha extract helps to reconstruct entire networks of your nervous system, and has huge implications for any athlete using CBD to manage head injuries or chronic pain.

Researchers have also found that ashwagandha helps support the growth of nerve cell dendrites, which allow these cells to receive communications from other cells, and that ashwagandha helps promote the growth of both normal and damaged nerve cells, suggesting that the herb may boost healthy brain cell function as well as benefit diseased nerve cells.

Most ashwagandha supplements have failed review by ConsumerLabs, so we opted for a water-soluble bioavailable formulation of ashwagandha, using the same nanoengineering technique as the CBD…

Lemon balm, AKA “Melissa Officinalis” was dedicated to the goddess Diana, and used medicinally by the Greeks some 2,000 years ago. In the Middle Ages, lemon balm was used to soothe tension, to dress wounds, and as a cure for toothache, skin eruptions, mad dog bites, crooked necks, and sickness during pregnancy, and as a medicinal plant, lemon balm has traditionally been employed against bronchial inflammation, earache, fever, flatulence, headaches, high blood pressure, influenza, mood disorders, palpitations, toothache and vomiting.

Because it provides the body with a calming effect, lemon balm is also used for nervous agitation, sleeping problems, functional gastrointestinal complaints, menstrual cramps and urinary spasms. It is thought that the volatile oils in lemon balm contain chemicals that relax muscles, particularly in the bladder, stomach, and uterus, thereby relieving cramps, gas, and nausea. Because of its calming effect without the potential to create the side effects of a sedative, lemon balm is also widely used to treat stress, anxiety and insomnia. This ability, along with lemon balm’s antiviral and anti-autoimmune characteristics have also made it useful for the treatment of thyroid issues chronic fatigue syndrome.

Recently, lemon balm produced an unexpected result: it greatly increased the ability to concentrate and perform word and picture tasks. In a study at Northumbria University in England, students were tested for weeks while using either lemon balm or a placebo. The students did significantly better on the tests after taking lemon balm and continued to post improved scores for up to six hours after taking the herb. The students taking lemon balm were noted to be calmer and less stressed during the tests.

Similar to the ashwagandha, the lemon balm in NatureCBD is also highly bioavailable.

The starch “filler” is from non-GMO brown rice. The hypromellose vegan capsules contain no soy, no nuts, no sugar, no yeast, no gluten, no dairy, no chemicals, no artificial flavors, no artificial coloring, and are lab tested to be free from toxins and other solvents.

We get it.

Many people are (and should be!) skeptical when they hear what a new product might do for them, especially when it’s a politically charged, controversial plant extract like CBD.

Q. Are nanoparticles safe?

A. There has been some fear around the subject of nanoparticles that has been spread by a few scientists that are not educated on distinct differences between different types of nanoparticles, and who are talking about a few specific nano-sized metals that may possibly have the ability to bind to DNA (e.g. cisplatin nanomolecules used in chemotherapy, or carbon nanoparticles from tattoos). But in the case of all natural polyphenols or other biodegradable nanomolecules, such as those found in NatureCBD, there is no chance of binding to any place in the body for a harmful period of time. This is because these natural molecules get metabolized into other forms in your body and are then easily excreted after getting their delivery job done.

Q. What are the usage recommendations?

A. General recommendations are as follows but you are advised to consult your healthcare professional: You can take on an empty stomach or with food, morning or night, 1 capsule per day for preventative care or general maintenance, 1-2 capsules at any time of day where you need more focus OR you're dealing with anxiety and stress, 2-3 capsules shortly before bed to help with sleep, 5 capsules is the suggested upper limit for any 24-hour period.

Q. What type of magnesium is used in this product?

A. The magnesium is derived from Epsom salt…magnesium sulfate.

    NatureCBD is everything Ben says it is.

    I have chronic stress, depression and anxiety, and after 2 caps and 90 minutes later, all anxiety had disappeared and my mood improved.

    I smoke cannabis to deal with the stress and depression, but I dont like the cognitive side effects.

    NatureCBD delivers everything I want without those side effects, and the difference is noticeable on the first dose.

    Highly recommended!

    Thanks Ben for bringing this to the market, I expect it will be a huge success.

Your products as healing agents seem to be exceptionally well engineered and their therapeutic benefits at last, are beginning to become more widely recognised.Alas, I am unable to acquire some as I live in Wales.UK.

    I've taken these capsules in the morning before a very mentally-taxing class, and I've found that my ability to focus is enhanced.

    I've also taken them to help me fall asleep, and again, my focus is enhanced – this time it's a focus on winding down and resting my brain and body.

    I'm enjoying this product, Ben! Thanks for making it available.

    I bet this is awesome but my question is what happened to the $89 price. The price increase has made it completely un-affordable for two adults as there is only 30 capsules in the bottle! We take other nutraceuticals and have a monthly budget to spend. I really want to add this but it is very un-affordable. Hopefully someday the prices will become reasonable for CBD products. In general the industry as a whole has made CBD unaffordable for regular people, it isn't a Ben Greenfield thing I am definitely not singling you out. Of all the CBD products out there this is the only one that seems like the best absorbed. I wish when amazing products like this come out that the people who discover them them wouldn't be so seemingly greedy and actually make it affordable. They would make just as much as more people could purchase vs only a select group of people who have big incomes.

    Very effective at relaxing and relieving stress. I am on my feet 10-12 hours/day, with a labor-intensive job, hiking, and rugby. I've taken the supplement in the morning and at night, in varying doses, with other supplements (valarian, rhodiola, siberian ginseng, magnesium) and by itself. For me, I noticed that I had the most potent relaxation with a double dose coupled with 500mg magnesium citrate. Seems to also take away the anxiety associated with smoking high THC strains, which is awesome. Overall, I'd give it 5 stars, but instead a 4. The $4 a capsule is a bit pricey for all but a select few.

    NatureCBD was very effective at relieving stress, anxiety (ie before big meetings with new clients) and related nausea. The only reason for the 3 stars and that I did not keep my subscription is the 150$ per bottle price with the shipping to Canada. Add in the exchange rate and it's over $200 a month.

    Definitely worth it! I felt so relaxed just 30 minutes after taking my first capsule! I was having headaches from work and less sleep. I realized that My headaches went away when I started taking these but that wasn’t it, I feel much more focused at work when I take one in the morning. Also when I eat lunch, I started to enjoy my meal much more than I used to before taking this product. Its only been a few weeks since I started using these capsules but so far I noticed no side effects and Overall I just feel much better and fresh! Its a bit pricey but I cannot complaint since it is improving my health significantly. Its like an all in one deal unlike other products which will only fix one symptom

    I have lived with Multiple Sclerosis for over twenty years, so.your product has a complex assignment. Today 1/29/16 I took my first capsule (minutes ago).

    I’ve been using PlusCDB Oil since November 2014, and had a myriad of subtle improvements in MS symptoms. More importantly, exacerbations are few and mild. This is the only “Disease Modifying Treatment” I use, having run the gamut of Big Pharma MS drugs. I’ve become a CBD proselytizer to other MS patients.

    So. If I was indeed only utilizing 1.5mg via the oil, your 10mg of fully-absorbed CBD should make a perceptible improvement right away. And over the months to come. I’ll be writing my follow-up review after I finish this first bottle.

    NOW can we talk about the price? I realize that your extraction and preparation processes are high tech and expensive – but hemp is not. I beg you to find a way to cut your price by at least 40%. So many people can benefit from Nature CBD but will find it cost-prohibitive.

    That’s classic Big Pharma right there, and that flies in the face of what the cannabis movement is fighting for. Are we paying for your research?

    Anyway – follow-up review forthcoming.

    Why can’t you make this product more affordable? I suffer from chronic anxiety and insomnia and would love to try this. I’ve tried using a CBD drip in my vape and the results are great but shortlived and I’m assuming a capsule would have more of a lasting effect. I’m extremely disappointed that this product is so overpriced I can’t even try it. I guess only the rich get to enjoy a truly good night’s sleep on a regular basis.

    I have chronic back (damaged disc) pain while being a half ironman distance triathlete and work at a desk 40 hrs per week. (Recently my boss treated me to a stand-up desk). As a female, 150lbs, what is a recommended dose for this? (Timing: ie before/after workout or before bed/first thing in morning and also amount: 1 or 2 caps per day?) Is it necessary to take everyday? (I’m thinking of cost-saving measures) Or just when I’m feeling stressed/sore/anxious or need to be focused?

    • Ben Greenfield

      Always consult healthcare professional before taking any supplements, including NatureCBD; everybody responds differently to CBD and depending on your tolerance of the product, 2-4 capsules 30-60 min before bed if you want to sleep better; or in the morning before breakfast if you want greater focus. Recommended upper limit per 24-hour period is 5 capsules.

    i do enjoy a mild peace/calming mood, i have been trying it friday evenings and catch up on a couple shows while laying in my recliner to decompress (i usually cant just sit and watch tv/movies, i’m playing on ipad or getting up and down constantly). However, at the price point i’m not sure i’m motivated to order again. Maybe at $99, but its not like i’m taking it daily so I would only need a bottle every 3 or 4 months so I don’t do the recurring. Love the idea Ben, appreciate your pursuit of a really unique product.

    I had to take 2 capsules to feel relaxed and it did work. I never have trouble falling asleep but have occasional problems staying asleep after 5-6 hours. This didn’t help me stay asleep. At $6.60/dose I have to give it up. Too expensive for the mediocre benefits. Truthfully I can take a single hit of weed at night and get the same result for far less money (I admit I am a weed lightweight). I don’t take a cognitive hit the next day at this dose of weed so I am going to stick with that.

    Clearly, Big Pharma rules the roost. It is a shame that I can file with my insurance for, say, Xanax, and pay just $4 for a month’s supply. Yet, they won’t cover CBD Oil – a product that works – and therefore I’d have to shell out anywhere from $238+shipping for 2 capsules per day to $595+shipping per month for the upper limit of 5 capsules per day.

    You’d think that in trying to market these ‘safe’ ‘natural’ ‘effective’ CBD products, the companies would attempt to make them more affordable.

    As more and more people have become aware of CBD in the past year or so, more and more people are purchasing CBD products. I can understand the price would be higher if few people purchased, but there has been a substantial increase in sales of CBD products in the past year or so, and the companies could well, and should, pass some of that savings onto the customer so that the average person could afford the CBD benefits!

    Yet, as usual it comes down to the bottom line… companies just aren’t going to budge on retaining those profits. Big Pharma has us in their glitches, but now so do the CBD manufacturers.

    I’ve tried the competitors bioabailable CBD and I’ve no doubt that your NatureCBD is all you claim. I rated a 3 only because of the price.

    My question Concerns the bioavailability. Rather than reply with “All CBD products vary” or “Cannot compare”, Please fill in the blank:

    A NatureCBD capsule, containing 10 mg of CBD, is the equivalent of taking a _____mg capsule containing the purest non-bioavailable oil based CBD available on the market today.

    Ok, so I just finished my first month or so (a little less since I started out taking 2 capsules per day), and although I had huge reservations about this product being able to help the enormous anxiety that I have experienced for years now, I can say unequivocally works. Is my anxiety gone 100%? No, but it is about 95% better, and allowed my to finally take my family on a much needed vacation with very few “anxiety” related problems like the last trip had. I have been able to function better at work now as well, filling in for my business partner so he could finally take a vacation as well. I’m not ready to rate this as a Godsend just yet, as this was the 1st product I’ve tried. I am going to now try a higher dosage capsule by another manufacturer, to see if the effects are the same, similar or better than these. I know the Tumeric is supposed to make this 10 mg. capsule more bioavailable, but again, I am a skeptic, and truth be told, these capsules make me very relaxed to the point where I only take them at night. It could be the other 3 ingredients that cause that, which is why I’m going to try some capsules without them, that have a 25 mg potency, and cost a little less than these do. I will post an update once I determine the difference in effects (if any). What I can say, is that if you want to buy this product, it definitely worked for me, and worked very well in alleviating what was debilitating anxiety, and I have no problem recommending it. I must mention also that I sleep all the way through the night when taking this, which I haven’t been able to do in years, so that could be contributing to lowering my anxiety as well. It’s all still in the testing phase for me at the moment.

Brain racing, stomach clenching crazy feeling.

    I recived the capsules and I have taken two before bed, two nights in a row. I have had the calmest,best sleep of my life. The calm and well being lasts well into the next day. Also, an interesting effect on my appetite. I’m not hungry in the morning. I usually make my coffee and have my breakfast within an hour of waking up and I don’t want anything first thing!

I tried the one bottle but wasn’t able to stop reshipment in time for the second bottle. You have a money back guarantee, I have not yet received the second bottle, could you PLEASE refund me. Our family is really struggling right now. Thank You

    I really like your NatureCBD but just read about some recent turmeric recalls due to lead contamination. Is this anything that I should be worried about?

    Can you tell me the difference between the pill form and the inhaled?

    I was so looking forward to trying the CBD oil capsules to help with insomnia due to imbalanced neurological hormones and adrenal exhaustion. Sadly, the night I tried it I was awake and wired with heart palpitations until 4am. I believe it was the addition of the adaptagenic herb Ashwagahnda that caused this paradoxical reaction because it is known to have this effect on some people. I would like to find a pure version of the capsules and have the option of adding other supplements myself since I was already taking magnesium, lemon balm, etc. I understand that the trend in natural health supplements is to add “proprietary” amounts of combinations to make a “better” version of things for a marketing edge but, unfortunately, so many with health struggles seeking natural healing tools have multiple sensitivities based on their stage of illness and combinations can be detrimental for that. Please don’t read the quote marks in the last sentence as intended to be sarcastic. I would imagine this combination may help someone, I just wish I would have considered this possibility before ordering a $100+ bottle.

    Disclosure –I didn’t buy this–I wanted to after listening to the podcast but at $100 a bottle no way I could sustain buying this. Who can afford to pay this each month on 1 supplement only?

    Also–only 10mg of the cbd seems low. I already take magnesium and lemon balm but I imagine theyre used to contribute to the relaxed feeling– so how much of the relaxation is actually from cbd? Also ashwaganda can be stimulating for some –I can’t take it for that reason. i guess if you got money to blow it might be worth a try but who can afford this on a regular basis??

      It's actually much MUCH less expensive (about 1/4 the cost) of the equivalent you'd pay for CBD in something like a marijuana store…it's a very good deal actually considering how many "doses" you get.

    I have used this product daily since my knee replacement three weeks ago. It works well to help me sleep at night with less reliance on opiate pain meds. I just ordered another bottle because I think I need the anti-inflammatory benefits and the help with sleep for a few more weeks. I tried taking this in the mornings hoping for improved pain relief during the day however it made me a bit lethargic. Best at night for me.

    My mom recently ordered 2 bottles of nature CBD, one for myself and one for her. I cant speak to her results due to the obvious fact that I don’t walk around in her shoes everyday but in regards to myself without telling to much about my past, I recently became sober and started a path of recovery not only in the sense of abstinence from illicit substances but in general. (physically, mentally, emotionally) I will not say any umbrella statements in relation to others but personally my levels of cravings for my particular drug of choice have gone down immensely and I don’t(can’t, due to probation) even smoke weed anymore. I’m praying this product won’t show up as THC on a drug test because that would essentially for lack of a better word fuck me and my legal situation but with that being said I very much so enjoy this product for its benefits on PAWS(post acute withdraw syndrome). I’m sure theres very little if not no study’s at all about this and I’m also sure that along with everything else this particular product effects everyone differently but for me it made quite a difference. thank you for taking the time to read this. – LUCAS T.

    I tried NatureCBD for a week, with zero effect. When I called to request a refund for this ineffective product, I learned that the 30-day guarantee is far from hassle-free, as Greenfield Fitness System requires returning the unused product and packaging before processing the guarantee.

      Sorry for the inconvenience Dustin, we do the best we can!

    I LOVE the hyper focus I have and lack of anxiety…since I started taking these. However, I am getting tons of facial flushing and red blotches. Its extremely embarrasdign at work. Can that be a side effect of the curcumin?

      This is likely a detox effect. I'd try a sauna protocol to accelerate detox and also drink PLENTY of good, clean filtered water with minerals.

    Unfortunately, you leaver the prospective customer with the option to “buy a pig in a poke”

    In other words, you give no idea as to how many capsules are in a bottle, nor the strength of

    eaach capsule, and the recommended dosage for effectiveness

    Would love to try but not at $119 a bottle. Those on a fixed income get screwed again!

    This is incredibly expensive!

    Having said that, this is also the only thing that had any effect on my girlfriend’s fibromyalgia. She takes 3 capsules per day so as you can imagine we are looking at 300/month expense. But its so worth it!

    For the last 3 years she was a ghost of her former self, in pain an unable to even do basic things for herself at times. After 1 week of this, she is back and pain free 90% of the time. Yes she still has fibro, yes she is still on all her other meds, yes this is not cheap, yes it worked for her!

    We have tried other forms of CBD and THC/CBD combinations, and none of them have been as effective as this formulation.

    One downside: it seems to cause minor hot flashes for first few days, but those seem to be going away.

    Hey Ben,

    I am very interested in purchasing nature cbd. I am a nurse and cannot have a positive test for any narcotic. Will this product show a positive result on any drug screens?

    • Ben Greenfield (verified owner)

      Unless they test for CBD (which isn't illegal) this product will not cause a positive blood test.

    Hi Ben

    You are the man – You have absolutely changed my life and way of thinking and have inspired me to really chase down my goal of being the best personal trainer/health coach/medical doctor I can be. Thank you so much.

    Anyway since these beauties are a pretty penny, I was hoping you could chime in on how to use them for maximum absorption. Between taking them after a 12-18 hour IF, blending it with fats in say coffee, or making into butter with something like the magical butter machine which provides the best absorption?

    • Ben Greenfield (verified owner)

      You can definitely break them open and blend them with things like ghee or coconut oil, black pepper, and turmeric… But they are already very highly absorbable because they are water-soluble…you only need to take about a 10th of what you would normally take for CBD… So there's really no need to do that.

    If you could offer 1 bottle at a reduced price for first time customers, you might find you’ll get more repeat customers. I would love to try this, but $119.00 is an expensive experiment. I would try it if I could buy just one bottle at the 6 bottle price of 73.80 apiece. If it’s everything it’s claimed, I’d be a regular customer.
