Excellent value - however not the best on the market

Purchased because it was cheap! However, compared to a practitioner-only product I usually purchase in Australia, it's not as fine (powder/granules) and does taste slightly different. I think this is myo-inositol, but I'm not 100% certain. I've been using it, but probably won't purchase again. Great on an empty stomach, easy to take on it's own.

If you need Inositol, but you don't want to add another pill to swallow, with different ingredients, you can choose this product and you simply put the powder into your daily beverage of choice. I wanted to try inositol for sleep and for perimenopause signs.

Calming, clean inositol — neutral taste, easy bedtime mix

Pure inositol with excellent quality and potency. Neutral taste, dissolves fast. I use 1/8 tsp at night with glycine; it noticeably relaxes the nervous system and helps me drift off. No niacin flush. Works well alongside folic acid and other B-vitamins that support energy and metabolism. Solid package and consistent effects; ingredients list is just inositol, so dosing (dosage) is easy and predictable. Overall great effect for sleep support and stress. Taste is mild/neutral.
