Summary
This vitamin C supplement contains a high potency dose of ascorbic acid, which is beneficial for immune support and overall health. The formulation is simple with only two additives, hypromellose and magnesium stearate, the latter of which is a common flow agent with some controversy regarding nutrient absorption. Despite the presence of magnesium stearate, the product maintains a clean label with minimal processing concerns.
