Effectiveness Rating: Arachidonic Acid vs Vitamin D3

The effectiveness rating is a measure of the supplements' ability to decrease body fat. This rating answers the question of whether or not a supplement does what it claims. The evidence shows vitamin d3 is better than arachidonic acid in its ability to decrease body fat. Vitamin D3 should provide some positive results while arachidonic acid will not.

Confidence Rating: Arachidonic Acid vs Vitamin D3

Another factor to take into account when comparing supplements is the confidence rating. This rating is a measure of how valid each supplement's effectiveness rating is. Remember, the confidence rating is a measure of how much you can trust the effectiveness rating. This rating is based on how many studies are included in the database on a supplement's claims. Ideally, you want a high effectiveness AND confidence rating.

Both arachidonic acid and vitamin d3 have low confidence ratings. This means neither supplement has an adequate amount of research to back up this claim. A low confidence rating questions the validity of the effectiveness rating.
