Effectiveness Rating: Branched Chain Amino Acids vs Glycerol

The effectiveness rating is a measure of the supplements' ability to improve cardiovascular endurance. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up glycerol to improve cardiovascular endurance is much better than the evidence backing up branched chain amino acids. Glycerol should provide positive results while branched chain amino acids will not.

Confidence Rating: Branched Chain Amino Acids vs Glycerol

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.

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