Effectiveness Rating: Caffeine Anhydrous vs Vitamin B1 (Thiamine)

The effectiveness rating is a measure of the supplements' ability to decrease fatigue. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up vitamin b1 (thiamine) is great, while the evidence backing up caffeine anhydrous is good. Vitamin B1 (Thiamine) should be able to decrease fatigue more effectively, however both supplements should provide positive results.

Confidence Rating: Caffeine Anhydrous vs Vitamin B1 (Thiamine)

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.

Caffeine Anhydrous's confidence rating is higher than vitamin b1 (thiamine)'s. This means caffeine anhydrous's effectiveness rating from above is more valid. This does not necessarily mean that caffeine anhydrous works better, it simply means the evidence (included in this database) backing up caffeine anhydrous is more established.
