Effectiveness Rating: Apple Polyphenol Extract vs Sodium

The effectiveness rating is a measure of the supplements' ability to improve cycling performance. This rating answers the question of whether or not a supplement does what it claims. Both apple polyphenol extract and sodium have good (but not great) evidence showing they may be able to improve cycling performance. Both supplements should provide some positive results.

Confidence Rating: Apple Polyphenol Extract vs Sodium

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.

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