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.

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. (, 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.

Kind of early to say how much this has helped

I’ve been a little lax taking this supplement but have been trying to take it more consistently. Overall I’ve seen some improvement in my skin. Having said that I’m also more consistent taking my fish oil which I believe also contributes to good skin health as well as a new probiotic from another company.
I trust this product line so I’ll be ordering more shortly.

Hi Sandra, Thank you for trusting our brand. We are happy you have found our Bio-Avail E and you are seeing improvements in your skin since taking it. We appreciate your review!

Richard Scranton
Best quality e on the market

After doing research I’ve found out that most e is subpar synthetic. This is the only natural version of e I could find. Truly love adapt naturals.

Hi Richard, We are glad you found Adapt Naturals and love our supplements. Thank you for your review!

helped with lab work!

I got this for my husband who has elevated liver enzymes for years, thanks to his Hashimoto's. After a little over a month of being on the Vitamin E, his liver enzymes were completely normal! I've been trying for years to find something to help, and this is the first that has ever done anything.

Hi Elizabeth, We are indeed delighted to hear your husband's liver enzymes are back to normal since taking our Bio-Avail E . We hope that he will notice other positive improvements as he continue this supplement. Thank you for your review!

High quality supplements

In a world of unregulated supplements, it’s hard to find high quality supplements that are third party tested. I really appreciate that these are what they say they are and there’s no additives or extra vitamins/minerals I don’t want included. It’s hard to find trust worthy companies these days, but this is a keeper!

Hello Megan, Thank you for trusting Adapt Naturals with your health. It's always amazing when something you trust actually works. We are glad to know you are pleased with our Bio-Avail E+. Thank you for leaving us a review!

I love all of the adapt products! My favorite are the magnesium and organ. It’s a relief knowing that what is on the label is what is actually in the products - I can feel the difference! I have way more energy and have sleep so well.

Hi Bailey, Thank you for reviewing our Bio-Avail E. It's great to know the Bio-Avail mag and Bio-Avail Organ are your favourite and you are noticing a difference in your energy and sleep. We hope you will receive all the benefit they have to offer. All the best!
