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.

Easy to digest

I’ve just began using Bio-Avail Mag and am finding it easy to swallow and digest. Often when I take magnesium, they seem to get caught as I’m swallowing and take a bit to break down, I’m not finding that is the issue with Bio-Avail Mag.

Just what I needed!

Since I have been taking Bio-Available Mag, my energy has increased, I feel mentally sharper, my sleep has improved, and so has my digestion. It has truly improved my quality of life.

Hi Nicole,

Wow—what a powerful testimonial! We’re so happy Bio-Avail Mag is supporting your sleep, digestion, energy, and focus. Magnesium is a foundational nutrient that’s often overlooked, and your experience shows how much of a difference it can make when it’s in a bioavailable, effective form. Thanks for sharing your story.

Helped Me Out

I was having trouble sleeping and had gotten a little constipated with this pregnancy, but bio-avail Mag helped me out on both fronts.

Thank you, Cara. We’re so glad Bio-Avail Mag is making a difference during such an important time. Magnesium plays a huge role in sleep and digestion—especially during pregnancy—and it’s wonderful to hear you’re getting the support you need. Wishing you continued ease and wellbeing!

The Best

I've tried other magnesium supplements and while some are good, Bio-Avail Mag seems to work wonders for me every night before bed. I used to get leg cramps regularly at night, but rarely anymore since using Bio-Avail Mag!

Hi D.G.

That’s amazing to hear! Leg cramps can be such a frustrating disruption to sleep, and it’s great that Bio-Avail Mag has made such a difference for you. Our carefully chosen forms of magnesium are designed for optimal absorption, so your body can actually use what you’re taking—especially when it comes to muscle relaxation and recovery.

Here’s to restful nights and cramp-free mornings! Thanks for sharing your experience. 🙌

Top notch

This is a top notch magnesium. I was using a different brand but once I saw that Chris Kresser had a magnesium I jumped on it. It helps me feel calmer. Thank you Chris and Adapt Naturals!

Hi Stacia,

Thanks for switching to Bio-Avail Mag! It's great to hear it's helping you feel calmer - that's one of the key benefits of our highly absorbable magnesium formula.

Many people don't realize how important the form of magnesium is for both absorption and effectiveness. We designed Bio-Avail Mag using a buffered chelate form specifically to maximize those calming benefits while minimizing the digestive discomfort that can happen with other magnesium supplements.
