While there's no proven method to safely and effectively increase melanin levels, some anecdotal evidence suggests that vitamin C might help boost melanin production. Consuming vitamin C-rich foods like citrus fruits, berries, and leafy green vegetables, or taking a vitamin C supplement, might contribute to this process.
However, it's essential to note that more research is needed to confirm these claims. Consult with a healthcare professional before making any significant changes to your diet or supplement regimen.
