The supplement ingredients listed in table below are identified as affecting Womens Hair, Skin and Nails Formula's ability to reduce muscle damage. The rating next to the ingredient describes the ingredient's ability to reduce muscle damage. These ratings are averaged together and provide the product's overall ability to deliver on the same claim.

Ingredients Reduce Muscle Damage Rating
Vitamin C 1.4 out of 3
Vitamin E 1.8 out of 3
N-Acety-L-Cysteine 1.3 out of 3
Methylsulfonylmethane (MSM) 2 out of 3
Green Tea Extract 1.9 out of 3
Product's Claim Effectiveness Rating 1.68 out of 3

Claim Research Ratings

The research rating describes how well an ingredient's ability to perform a certain claim (such as reduce muscle damage) has been researched. This rating is based on the amount of studies contained in the database on a particular ingredient and claim. Ingredient research ratings are averaged together to from the product's research rating for this specific cliam.

This rating is important because we need to know if there is enough research to make a valid conclusion on a product's worthiness. Ratings above 80 are ideal. Anything below 60 means there is not enoguh research to make a valid conclusion one way or another on a product's ability to deliver on this particular claim.
