Effectiveness Rating: Beta Alanine vs Potassium

The effectiveness rating is a measure of the supplements' ability to improve sprint performance. This rating answers the question of whether or not a supplement does what it claims. The evidence shows beta alanine is better than potassium in its ability to improve sprint performance. Beta Alanine should provide some positive results while potassium will not.

Confidence Rating: Beta Alanine vs Potassium

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.

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