Effectiveness Rating: Sustamine vs Tongkat Ali (Eurycoma Longifolia)

The effectiveness rating is a measure of the supplements' ability to improve running performance. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up sustamine to improve running performance is much better than the evidence backing up tongkat ali (eurycoma longifolia). Sustamine should provide positive results while tongkat ali (eurycoma longifolia) will not.

Confidence Rating: Sustamine vs Tongkat Ali (Eurycoma Longifolia)

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 sustamine and tongkat ali (eurycoma longifolia) 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.
