Detailed Dosing Report

The detailed dosing report breaks down how each study rated a specific dose. Additionally, this report also provides daily frequency of a dose.

Note: sometimes, studies may find smaller doses are more effective than larger ones. Rather than focusing on specific numbers, look at the range of effective doses when evaluating how much of a supplement you should take.

The first column (dosage) is the amount of the supplement taken per sitting. The next column (frequency) is the number of times the dosage was taken each day. The third column (daily total) is dosage multiplied by frequency. The final column (effectiveness) is how well that dose worked for the specific claim.
