Recent studies in biochemistry highlight vitamin C's dual nature, acting as both an antioxidant and a potential pro-oxidant under certain conditions. The question, can vitamin C increase oxidative stress, hinges on complex factors including dosage, presence of free metal ions, and overall cellular environment. This duality is crucial for understanding its full effects on the body.

Overwhelming evidence suggests that at physiological levels, vitamin A and its precursor carotenoids act as powerful antioxidants, protecting against oxidative damage. However, the answer to the question "Is vitamin A an antioxidant or a pro-oxidant?" is more complex, revealing its dual-natured role in human health.

High doses of certain antioxidant supplements like beta-carotene have been linked to increased risks of cancer and cardiovascular disease in some populations. So, can you overdo it with antioxidants? Yes, and the risks of excessive intake may surprisingly outweigh the rewards.
