Why Choose Bio-Avail E+?
Vitamin E is an essential micronutrient that 89% of Americans don’t get enough of. Yet studies show that supplementing with the most common form of vitamin E, alpha-tocopherol, doesn’t improve health over the long term—and, in fact, can increase the risk of cancer and heart disease. Bio-Avail E+ contains 300 mg of delta- and gamma-tocotrienols, a recently discovered form of vitamin E that has far greater health benefits than alpha-tocopherol and none of its long-term risks.
Formulated to Restore Youthful Vitality and and Slow Aging
From processed food to environmental toxins to chronic stress, the modern world makes health hard. Bio-Avail E+ was formulated with delta- and gamma-tocotrienols to rejuvenate the body and mind and slow the aging process. This means stronger bones, healthier cells, a more youthful and radiant appearance, and more protection against aging and the challenges of daily life.
Harness Years of In-Clinic Experience and Ancestral Wisdom
Backed by Adapt Naturals' 15 years of in-clinic experience and dedicated to creating supplements that make a meaningful difference, Bio-Avail E+ combines cutting-edge research with insights from ancestral wisdom to bring you a premium-quality supplement.

Your Questions Answered
Bio-Avail E+ is best taken with food. We recommend taking the single gel-cap serving with dinner, but it can be taken at any time of day.
Studies have shown that alpha-tocopherol, the most common form of vitamin E that is typically found in supplements, may interfere with the benefits of tocotrienols at higher doses. (https://jamanetwork.com/journals/jama/article-abstract/205797, https://www.ahajournals.org/doi/epdf/10.1161/ATV.0000000000000153) For this reason, we suggest limiting your intake of alpha-tocopherols in supplements to 10 mg per day.
We get about 10 to 15 mg/d of tocopherols in our diet, mostly from foods like nuts, seeds, and vegetable oils. At this level, tocopherols have a beneficial or neutral effect.
Yes, all Adapt Naturals products, including Bio-Avail E+, undergo rigorous third-party testing for purity and potency.

I have been on several Adapt Naturals products for a few months now and I feel pretty good on them. I can’t say which is doing what, because I am taking them as a set, but overall I do like them!
Hey Valerie,
Feeling good across the whole Adapt Naturals lineup and the DeltaGold® delta and gamma tocotrienols in Bio-Avail E+ supporting healthy cell membranes and cardiovascular function as part of that bigger picture is exactly how Chris intended it to be used. We are so grateful for your loyalty and thank you for sharing!
Very happy with thenproduct
Hi Mary,
Delta and gamma tocotrienols are the forms almost nobody supplements with, and it took some work to get a version with zero alpha-tocopherol diluting things. Glad it's working for you.
I cannot tell of any magic that these pills do. But from the science behind it, this is a fantastic product.I keep ordering these to Europe. In Europe, I haven’t found the same dosage for the same price. And I trust in Chris’ quality products.
Hey there,
Trusting the science and ordering all the way to Europe! We are so honored and grateful! The DeltaGold® tocotrienols in Bio-Avail E+ are the most clinically studied tocotrienol material available and the concentration and quality really are hard to find anywhere else at this price point. Thank you so much for your loyalty and for sharing!
This seems to help repair and protect skin and eye health.
Hey Laura,
Skin and eye health both responding is the DeltaGold® tocotrienols doing their thing! This highly concentrated form of vitamin E supports healthy cell membranes in the delicate tissues throughout the body and we are so glad you are noticing the difference. Thank you for sharing!
I bought this to help lower my ApoB. It's dropped from over 100 to just under 90.
Hey Jayne,
ApoB dropping from over 100 to just under 90 is a genuinely meaningful result and we are so glad you are tracking it so closely! Bio-Avail E+ uses DeltaGold® which is 90% delta and 10% gamma tocotrienols from the annatto plant and is the most clinically studied tocotrienol material available. Research shows that tocotrienols may help reduce cholesterol by inhibiting an enzyme called HMG-CoA reductase which is involved in cholesterol production in the liver. Keep going and keep sharing those numbers with your healthcare provider. Thank you so much for sharing!

I don't know how a person can write an honest review when they've only had 2 weeks to try it out. So far there's no stomach upsets or anything of that nature but there has certainly been no improvement in 2 weeks.
Hi Lisa,
Thanks for checking in early—and for noting the lack of side effects. Our tocotrienol-based vitamin E supports cellular health and antioxidant protection over time, so we’re hopeful you’ll begin to notice more benefits in the coming weeks. And if not, you’re always covered by our 60-day guarantee.
So far, I'm satisfied with my monthly subscription of Bio-Avail E+. I like the little attractive amber colored bottle that my capsules come in. I also like swallowing capsules better than swallowing tablets. Taking this product gives me peace of mind that I am taking the best form of Vitamin E to combat my heart disease (long-standing persistent atrial fibrillation along with the potential of developing heart failure which is a common ending result of having chronic atrial fibrillation like I have. By getting this peace of mind by taking Adapt Natural's high quality products, this also helps my condition because it helps me lower my stress and anxiety which both are directly related to exacerbating atrial fibrillatin. I'm hoping that Adapt Natural's high quality & advanced nutritional products will help slow the progression of my disease helping me to live as long as I possibly can despite my heart disease. I am very thankful to you Chris for your unique nutritional company and you dedication and goal to help others achieve their optimal health. Sincerely, Peter Aiello

Its helping my skin from the inside out. Always had incredibly dry skin, but nothing has helping me like the vitamin E. No longer look like a dragon!
Hey Rachel,
No longer looking like a dragon...we love this! Vitamin E is such a powerhouse for skin nourishment from within, and we're thrilled it's making a real difference for you. Thank you for sharing!
I haven't yet been taking these for a month, but I am whole-heartedly on board with the science that backs these E+ supplements. Excited to see if I can feel/see the impacts!
Hey Ava!
That's awesome - we love that the science won you over! The research behind tocotrienols (the form of vitamin E in Bio-Avail E+) is really compelling - they're up to 60x more potent than regular tocopherols for certain functions and provide unique support for cardiovascular and cellular health. We're excited for you to see and feel the impacts as you continue taking it! Keep us posted on your experience!

At the suggestion of my radiation oncologist, I started using vitamin E to calm nerve damage from my cancer radiation. Bio-avail e has successfully quieted the tingling nerve sensations that I had been experiencing.

I have been taking BioAvail-e for almost a year now with the goal of making my lipid panel numbers better. I have been eating the same diet for over a year. BioAvail-e reduced my total cholesterol and LDL by 30 points within this last year.

This is incredible news—thank you for sharing! Bio-Avail E+ delivers delta- and gamma-tocotrienols, the most powerful forms of vitamin E shown in research to support cardiovascular and metabolic health. We’re so glad you’ve seen such meaningful improvements in your cholesterol numbers!

Please reach out to our support team so we can investigate and make things right as quickly as possible. That way, we can also keep you updated directly via email about your order status. We really appreciate your patience and look forward to resolving this for you soon.
I have been taking the Bio-Avail E+ for a few months now mostly just because I trust Chris's products.
I didn't really expect to see any changes in my labs though. However, I just got a panel done with Function Health and my lipids improved quite a bit!
My small particle LDL (a risk factor for HD) went down back into normal range and my triglycerides and ApoB both improved as well. Addin this supplement in was the only change I had made.
Thanks Chris!
Hi Karl,
Thank you for this amazing update—we’re thrilled to hear about the improvements in your lipid panel! Bio-Avail E+ is formulated with delta- and gamma-tocotrienols, which emerging research suggests that it supports cardiovascular and metabolic health more effectively than standard tocopherol-based vitamin E. We're honored to have played a part in your journey and grateful for your continued trust in Adapt Naturals. Take care!
My 50-something skin was looking dull and had lost its quick-healing nature. I’ve noticed a definite improvement since starting Bio-Avail E+. I trust Chris and love that his products are science-backed and clinician formulated. I also love Adapt’s eco-friendly packaging ;)
Hi Jill,
So glad you’re seeing results! Bio-Avail E+ is formulated with pure tocotrienols—a superior form of vitamin E that supports skin elasticity, cell protection, and metabolic health. We love hearing how it’s restoring your skin’s resilience. And thanks for noticing our eco-friendly packaging—we’re proud to deliver high-impact products with a low-impact footprint.
I started to take take Bio Avail E+ to support healing for Frozen Shoulder. After 2 weeks, I noticed my hair is growing in thicker and stronger. I’m sure the shoulder will take time but I saw immediate hair and skin improvement. I am hooked and bought some for a family member as well.
Hi Kate,
What a fantastic surprise—thank you for sharing! Bio-Avail E+ uses pure tocotrienols, which not only support cellular health but also promote skin and hair vitality. We’re so glad it’s delivering multiple benefits for you (and your family)!
I'm working on healing my skin and this supplement seems to be helping it feel smoother and softer. It's a small capsule so easy to include in a daily wellness routine. And I feel good knowing it's high quality!
Hi Elizabeth,
Wonderful to hear! Bio-Avail E+ is packed with delta- and gamma-tocotrienols—powerful forms of vitamin E that support skin elasticity, hydration, and cellular renewal.
We’re glad it’s becoming a go-to in your wellness routine.
Love this vitamin E that is a mix of tocotrienols. Tocotrienols have been proven to be beneficial for improving bone density as well as supporting fatty liver. My husband and I both take Bio-Avail E+. We love the quality and the clean ingredients.
Hi Nicole,
Thanks for this thoughtful review! Most vitamin E products focus only on tocopherols, but we created Bio-Avail E+ to feature pure tocotrienols—shown in research to support cellular health, bone density, and liver function. We’re so glad both you and your husband are feeling the difference!
I like it has plant base Toco-Treinol.
Hi Luis,
Thanks for your review of Bio-Avail E+!
We hope you're experiencing the many benefits this product offers.
Thanks for trusting in Adapt Naturals!
Great product as advertised. Skin looks great even in Dry MT winter
Thanks for sharing your experience with Bio-Avail E+! It's great to hear that it's helping your skin look good even through Montana's dry winter. Those delta- and gamma-tocotrienols really do work wonders for skin health and hydration.
It's a simple matter of trust. Which has become pretty complicated these days. Who else but Chris Kresser is going to tell me, and tell me the truth, about tocotrienols vs tocopherols…? No one else that I'm aware of.
The researched-based approach. The ongoing educating. A lot of generosity there. And the much-appreciated infusion of count-onable quality and much-needed sincerity into the supplement landscape. There is no one else doing what this company is doing. Thanks for doing it. And thanks for making Bio-Avail E+. We need it.
Hi SS, Thank you for trusting us with your health. We are glad to hear that you're loving our Bio-Avail Vitamin E+. We appreciate your continued support and thank you for sharing your experience with us. All the best!
