Effectiveness Rating: L-Theanine vs Lemon Balm Extract

The effectiveness rating is a measure of the supplements' ability to improve sleep quality. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up lemon balm extract is great, while the evidence backing up l-theanine is good. Lemon Balm Extract should be able to improve sleep quality more effectively, however both supplements should provide positive results.

Confidence Rating: L-Theanine vs Lemon Balm Extract

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 l-theanine and lemon balm extract have low confidence ratings. This means neither supplement has an adequate amount of research to back up this claim. A low confidence rating questions the validity of the effectiveness rating.
