The Claim
In rats, mineral supplementation caused gray hair to revert to black, whereas control rats on an isocaloric diet without mineral supplementation retained their gray hair.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Scientists found that when rats were given extra minerals, their gray hairs turned back to black—but rats that didn’t get the minerals stayed gray.
