Kirkman Reduced L-Glutathione provides 100mg of L-Glutathione per capsule. This dose is on the lower end compared to many other standalone glutathione supplements available, which often range from 250mg to 500mg.
The product also contains Calcium (as Dicalcium Phosphate) and Phosphorus (as Dicalcium Phosphate). While these are common excipients, their presence might make the product less suitable for individuals who are not specifically looking for supplemental calcium and phosphorus.
As a single-ingredient product (plus minerals), its focus is clear. However, considering the 100mg dosage and the price per serving, it may not be the most economical choice for those seeking higher glutathione intake.
