Effectiveness Rating: Caffeine Anhydrous vs Multivitamins

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

Confidence Rating: Caffeine Anhydrous vs Multivitamins

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 caffeine anhydrous and multivitamins have great confidence rating. This means both supplement's effectiveness ratings above are valid.
