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.

Good For You—And the Planet

You can’t have healthy humans without a healthy planet. That’s why Adapt Naturals is working toward zero plastic and landfill waste in our supply chain.

In the fall of 2023, we started transitioning our packaging to 100% compostable, stand-up pouches. They’re made from cellulose (wood pulp) and are free of PLA, BPA, PFAS, phthalates, and other harmful chemicals. They’re printed with non-toxic, compostable ink. The pouches are so clean and biodegradable that you can put them in your backyard or curbside compost bin! 

Our sustainable packaging initiative will prevent over 120,000 plastic bottles from ending up in a landfill or the oceans. Thank you for being part of the solution and helping Adapt Naturals protect the beauty of our natural environment!

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.

Great product just don’t like it in bag as opposed to bottle

Hi Carrie, We are happy you are loving our Bio-Avail E and apologize that we are no longer shipping in glass bottles. Adapt Naturals is committed to protecting our natural environment and reducing single-use plastics and landfill waste. While glass bottles were a good step in that direction, they require a lot of energy to produce and ship. They’re also fragile and have a high breakage rate. Our pouches are made from wood pulp and are 100% compostable. They require far less energy to produce and ship and don’t need to be recycled—they’ll break down quickly in a landfill or municipal/backyard composting system. Best of health to you!


Awesome! Using this to improve my lipids and keep my heart healthy.

Hi Karl, We hope you will experience all the benefits of our Bio-Avail E. Thank you for your continued support and for leaving us a review!

Great product

I take this daily and believe it is making me feel better. It's much better than what I used to take. I'm aiming for stronger bones, a better working immune system, and an improved lipid profile!

Hi Donna, We are happy you are pleased with our Bio-Avail E and the benefits you have received. Thank you for choosing Adapt Naturals as your supplement provider. Best of health!

Kira Miftari
Bio-Avail E+

Bio-Avail E+ has become a staple in my supplement stack, and I chose Adapt naturals bcs of how clean the ingredients are. Full spectrum tocotrienols have been proven to be extremely beneficial on multiple health fronts (listen to Bary Tan speak in this topic), but I cant imagine getting meaningful amount in our daily diet, so I take a capsule every day as an insurance policy.

Hi Kira, Thank you for supporting Adapt Naturals. We are indeed happy to hear you are getting the benefits you need from our Bio-Avail E. All the best in your supplement journey!

The first multi vitamin that makes me feel different

I have been taking multivitamins for years. I was even taking several special supplements prescribed by my functional doctor. These multivitamins make it so much easier to fit into my busy life and I noticed more energy.

Hi Sarah, We are thrilled to know you are getting all the energy you need from the Bio-Avail E. We appreciate your support and for sharing your experience.
