Effectiveness Rating: Beetroot Juice vs Sodium

The effectiveness rating is a measure of the supplements' ability to improve sports performance. This rating answers the question of whether or not a supplement does what it claims. The evidence shows neither beetroot juice nor sodium has the ability to improve sports performance. Neither supplement will provide positive results for this claim.

Confidence Rating: Beetroot Juice 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 beetroot juice'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.
