The ingredients in Corti-Glow are sold over-the-counter as dietary supplements. But if you take medications for thyroid, blood pressure, hormone therapy or antidepressants, consult a doctor. Ashwagandha may interact with thyroid medications, and magnesium can affect absorption of some antibiotics.

Myo-inositol is a vitamin-like compound the body makes on its own, around two grams a day; the rest comes from food, mostly citrus, legumes and whole grains. It is the most common of the nine inositol isomers: about 95% of the inositol in the body is this one. The sachet contains 2000 mg, the largest single amount in the formula. For comparison, inositol capsules on the shelf are usually 500 or 600 mg. It is not a medicine and does not replace treatment.

They are different forms of magnesium, and each carries a different amount of magnesium. Corti-Glow uses bisglycinate, magnesium bound to the amino acid glycine: 670 mg of bisglycinate give 134 mg of magnesium, 35.7% of the reference intake. We print both figures so you can compare with what you already have at home.

300 mg of ashwagandha root extract (Withania somnifera) per sachet. From the root, not the leaves, and on its own line on the box.

Seven active ingredients, each with its own amount: L-glycine 2000 mg, myo-inositol 2000 mg, magnesium 134 mg (from 670 mg of magnesium bisglycinate, 35.7% of the reference intake), ashwagandha root extract 300 mg, choline 250 mg, L-theanine 200 mg and vitamin B6 1.4 mg (100% of the reference intake). For taste and colour: prebiotic fibre (fructooligosaccharides), stevia, apple cider vinegar, natural forest-fruit flavouring and red grape skin extract. One sachet weighs 6.56 g.
