Why Choose Bio-Avail Mag?

Our modern diets often fall short of providing the optimal amounts of essential nutrients our bodies need to function at their best. With Bio-Avail Mag, you can optimize magnesium intake and support your overall health and well-being—without the unpleasant GI side effects associated with inferior forms of magnesium.

Formulated to Replicate Optimal Ancestral Diets

Changes in dietary patterns, declining soil quality, and a growing toxic burden have made it increasingly difficult to obtain adequate nutrients from our daily food intake. Bio-Avail Mag is designed to address these challenges by providing a highly bioavailable form of magnesium that gets absorbed quickly and is easy for the body to use.

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 Mag 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 Mag is best taken with food. We recommend taking the daily two-capsule serving with dinner to promote optimal sleep and relaxation and healthy elimination the following day.

Many magnesium supplements on the market contain magnesium oxide or magnesium citrate. These forms of magnesium are not as well-absorbed as the Buffered Magnesium Chelates that we use in Bio-Avail Mag, which bypass typical routes of absorption and are thus less likely to cause the unpleasant gastrointestinal effects associated with less bioavailable forms of magnesium.

Yes, all Adapt Naturals products, including Bio-Avail Mag, undergo rigorous third-party testing for purity and potency. Most importantly, we transparently share these results with our customers by posting Certificates of Analysis (CoAs) and test results on our website. This level of openness is almost unheard of in the supplement industry. It allows you to see exactly what’s in the product you’re putting into your body. Click here to view the most recent CoA and test results.

Mag works as expected!

This Mag supplement works as expected.

Great addition to my supplements

I added Magnesium and Omega+ supplements to my routine. Both are providing a good addition to my well-being. My overall health has improved greatly since I started taking supplements from Adapt Naturals. In addition to these two, I also take Bio-Avail Myco and Biome Protect. For someone who suffers from IBS these products are, in my case, very helpful

Hi Brian,

Thank you for sharing your experience—and for making Adapt Naturals a part of your daily wellness routine. It’s so great to hear that the Mag, Omega+, Myco, and Biome Protect formulas are supporting your well-being. We truly appreciate your continued support!

Swear by this company and their products

I have been taking several supplements by adapt naturals for over a year in an attempt to manage menopause, sleep, weight gain, eczema and overall vitality. It has been a game changer. I feel better now than 10 years ago.

Hi Nonie,

Your message means so much! What a review! Thank you. Supporting sleep, mood, skin, and hormone balance through clean, bioavailable supplements is exactly what we’re here for. We’re honored to be part of your wellness journey and thrilled you’re feeling stronger than ever!

Magic magnesium

Adapt Naturals Mag is very easy to tolerate even up to 400mg. My sleep rest cycle has improved tremendously- I don’t go a day without it. When coupled with Omega- my hair nails and skin reap the benefits as well as lowering my cholesterol levels - a plus. I recommend Adapt Naturals for anyone that wants to see and measure results with well delivered supplements.

Hi Mar,

This is such a great review, thank you! Bio-Avail Mag features a highly absorbable chelated form of magnesium that supports deep sleep, calm, and metabolic function. And yes, pairing it with Omega+ amplifies benefits for skin, hair, nails, and cardiovascular health. We're so glad you’re seeing measurable results across the board

Hi Suzy,
