Effectiveness Rating: Multivitamins 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. Both multivitamins and vitamin b1 (thiamine) have great evidence backing up their ability to decrease fatigue. They should both provide positive results.

Confidence Rating: Multivitamins 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.

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