When testing the effectiveness of supplements, researchers use specific doses to gauge whether or not an ingredient is effective or ineffective. The Supplement Database includes 17 studies on whey protein dosing. These studies indicate an effective dose ranges from 10 to 56 grams per day, the average dose being 41.82 grams per day.

A single study typically tests a specific dose of a supplement against a number of claims. Studies generally come to one of three conclusions: 1) the supplement was extremely effective, 2) the supplement was moderately effective, 3) the supplement was ineffective. The only doses listed on this page are ones which studies found either moderately or extremely effective. Ineffective doses are not shown.

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.
