Effectiveness Rating: HMB vs Vitamin D3

The effectiveness rating is a measure of the supplements' ability to decrease body fat. This rating answers the question of whether or not a supplement does what it claims. Both hmb and vitamin d3 have good (but not great) evidence showing they may be able to decrease body fat. Both supplements should provide some positive results.

Confidence Rating: HMB 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.

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