Effectiveness Rating: Choline Bitartrate vs Docosahexaenoic Acid (DHA)

The effectiveness rating is a measure of the supplements' ability to improve memory. This rating answers the question of whether or not a supplement does what it claims. The evidence backing up docosahexaenoic acid (dha) to improve memory is much better than the evidence backing up choline bitartrate. Docosahexaenoic Acid (DHA) should provide positive results while choline bitartrate will not.

Confidence Rating: Choline Bitartrate vs Docosahexaenoic Acid (DHA)

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.

Docosahexaenoic Acid (DHA)'s confidence rating is higher than choline bitartrate's. This means docosahexaenoic acid (dha)'s effectiveness rating from above is more valid. This does not necessarily mean that docosahexaenoic acid (dha) works better, it simply means the evidence (included in this database) backing up docosahexaenoic acid (dha) is more established.
