The CogniMary Blog
Longer answers to narrower questions. Each post is written to be useful whether or not you buy anything, and each one links its sources so you can check them.
The CogniMary blog covers the parts of supplement labels that decide whether a product is worth buying: proprietary blends and the arithmetic that exposes them, mineral forms and why the bracket after the word magnesium matters, what a 10,000 percent Daily Value figure actually means, and buying questions such as the 3-bottle pack, free shipping and whether there is a subscription. Written by the CogniMary Team and medically reviewed by Dr. Harald Hampel, MD, PhD; revised October 30, 2026.
