Effectiveness Rating: 5-HTP vs Multivitamins

The effectiveness rating is a measure of the supplements' ability to improve cognitive ability. This rating answers the question of whether or not a supplement does what it claims. The evidence shows multivitamins is better than 5-htp in its ability to improve cognitive ability. Multivitamins should provide some positive results while 5-htp will not.

Confidence Rating: 5-HTP vs Multivitamins

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 5-htp and multivitamins 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.
