Vitamin C 500mg Pill Review: Immunity Boost & Skin Benefits

Vitamin C is probably the most popular vitamin out there, known for improving immunity, skin health, and more. Dr. Linus Pauling argued that humans used to make vitamin C like most other mammals, but now we can't because of a genetic mutation way back in our evolution. Thus, we may need a lot more vitamin C than we think.

I have taken it since I was in high school. Just be aware that sometimes you can have too much of a good thing. Some research suggests too many antioxidants (like vitamin C) might not be a good thing. I cap my daily vitamin C at around 500 mg for this reason.

This is a good vitamin C pill and provides 500 mg per capsule. Nutricost claims third-party testing, which is good to see. I have had good experiences with their products.

Vitamin Basics & Tips

Vitamin C, or ascorbic acid, is a water-soluble nutrient essential for collagen synthesis, immune function, and antioxidant protection. Humans lack the enzyme L-gulonolactone oxidase required to synthesize vitamin C due to an ancient genetic mutation, making dietary intake or supplementation critical. The recommended daily allowance (RDA) for adults is 75–90mg, but some studies suggest higher doses (up to 500mg) may enhance immune response and skin health by promoting collagen production and neutralizing free radicals.

However, excessive intake (over 2,000mg daily) may cause gastrointestinal discomfort or paradoxically act as a pro-oxidant in certain conditions. Vitamin C works synergistically with other antioxidants like vitamin E and zinc. Natural sources include citrus fruits, bell peppers, and broccoli. Supplements like Nutricost’s 500mg capsules offer a convenient alternative, especially when third-party testing ensures purity and potency.

Emerging research debates the long-term effects of high-dose antioxidants, emphasizing balance. For optimal benefits, pair supplementation with a varied diet and consult healthcare providers to tailor intake to individual needs.
