Effectiveness Rating: Multivitamins vs Phenylalanine

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

Confidence Rating: Multivitamins vs Phenylalanine

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.

Multivitamins's confidence rating is higher than phenylalanine's. This means multivitamins's effectiveness rating from above is more valid. This does not necessarily mean that multivitamins works better, it simply means the evidence (included in this database) backing up multivitamins is more established.
