Effectiveness Rating: Beetroot Juice vs Sodium

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 shows beetroot juice is better than sodium in its ability to improve running performance. Beetroot Juice should provide some positive results while sodium will not.

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.

Both beetroot juice and sodium have great confidence rating. This means both supplement's effectiveness ratings above are valid.
