Our Myo-Inositol is 100% PURE Myo-Inositol, which is the most abundant isomer found in cell membranes. Research has shown that myo-inositol helps you fall asleep faster, supports healthy neurotransmitters, including GABA and serotonin, and supports healthy blood sugar, which, in turn, supports metabolic flexibility.

What is Inositol?

Inositol is a naturally occurring sugar found within cell membranes that plays a critical role in various processes including the functioning of peripheral nerves, osteogenesis, reproduction and fertility, and carbohydrate metabolism. Myo-inositol can be thought of as a second messenger within the body.

While sometimes referred to as Vitamin B-8, it is not a true vitamin since our bodies can synthesize their own and it is found in many common foods such as grains, beans, nuts, and fruits.

Interestingly, each kidney makes 2gm/day, and the liver and brain can also produce inositol. This remarkable molecule is one stereoisomer of a C-6 sugar alcohol and makes up 95% of free inositol in the body.

High quality product!

I love that the powder dissolves very quickly and has no taste. I can just put it in about 4 ounces ofwater right before bed. I like the high-quality bag and scooper as well. The product seems to work pretty well in aiding better sleep along with my melatonin. Thank you Cynthia Thurlow for your dedication to making this a high quality product.

Love it but with caution…!

This Mg supplement is doing a great job helping me sleep!! BUT. 2 capsules b4 bed with a meal caused some pretty impressive diarrhea the next day for about 2 weeks b4 I realized what was causing it!! Now, I take 1 capsule before bed. Still helps me sleep with no unpleasant side effects!!

Christopher S. (Richboro, US)

Unlike many supplements you will feel this day one! I combine Cynthia's Alpha GPC with MD Logics Alpha Lipoic Acid and the synergy for brain support and physical endurance is amazing. I literally cut down to one cup of coffee a day and sometimes half or none! Tremendous focus, long duration of concentration and cognitive activities. This stuff absolutely works! Best part from my experience, unlike extra coffee; no jitters, no anxiety and no crash from this combo! These two are definitely worth a try!!!!
