Effectiveness Rating: D-pinitol vs Vitamin D3

The effectiveness rating is a measure of the supplements' ability to increase strength. This rating answers the question of whether or not a supplement does what it claims. The evidence shows vitamin d3 is better than d-pinitol in its ability to increase strength. Vitamin D3 should provide some positive results while d-pinitol will not.

Confidence Rating: D-pinitol vs Vitamin D3

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.

Vitamin D3's confidence rating is higher than d-pinitol's. This means vitamin d3's effectiveness rating from above is more valid. This does not necessarily mean that vitamin d3 works better, it simply means the evidence (included in this database) backing up vitamin d3 is more established.
