He joined me on niacin 2 1/2 years ago. A few months later his haircutter of 15 years asked him if he had gotten implants. No, he said, why? His bald spot had grown back.
Not long afterward he noticed the return of nearly 100% of his visual field in the affected eye. The cholesterol that had been clogging the capillaries in the retina had apparently been dissolved by the niacin.
If your brother is going into his later years he might also get a boost from turmeric. Especially with respect to the water system. Helps maintain flexibility.
What about niacin and liver damage?
