Effectiveness Rating: Creatine Monohydrate vs Tryptophan

The effectiveness rating is a measure of the supplements' ability to decrease fatigue. This rating answers the question of whether or not a supplement does what it claims. The evidence shows tryptophan is better than creatine monohydrate in its ability to decrease fatigue. Tryptophan should provide some positive results while creatine monohydrate will not.

Confidence Rating: Creatine Monohydrate vs Tryptophan

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.

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