Summary
This vitamin C supplement contains several additives such as magnesium stearate and polyethylene glycol, which are common in supplement manufacturing but can detract from the purity and absorption of the active ingredient. While these additives are generally considered safe, their presence in the formulation reduces the overall quality compared to more minimal-ingredient supplements. The product is also highly processed, which is typical for supplements, but the use of synthetic additives impacts its score.
