Strong, radiant skin isn’t just about the creams and serums you apply—it starts from within. Collagen, the protein that keeps skin plump, elastic, and youthful, relies on a combination of nutrients to be produced effectively. Dr. Liu, double-boarded in Infectious Disease and Internal Medicine, shares her top three nutrients to boost collagen production while supporting immunity.

1. Beta-Carotene
Beta-carotene, a precursor to vitamin A, contributes to skin cell turnover and overall skin health, making it a vital nutrient for collagen production. It protects against free radical damage caused by UV exposure and environmental stressors. Sweet potatoes, carrots, and dark leafy greens are excellent sources of beta-carotene. Regularly incorporating these foods into your diet helps maintain skin elasticity while supporting your body’s natural ability to generate collagen.
2. Sulforaphane
Sulforaphane is a potent antioxidant found in cruciferous vegetables such as broccoli, cauliflower, and Brussels sprouts. It protects skin cells from oxidative stress, which can break down collagen and lead to premature aging. Beyond its antioxidant benefits, sulforaphane may help improve skin texture and tone by reducing inflammation. Dr. Liu recommends including cruciferous vegetables regularly, whether raw, steamed, or lightly sautéed, to support both skin and overall health.
3. Chlorophyll
Chlorophyll, the green pigment in plants, supports detoxification and helps maintain skin health by improving circulation and promoting cellular repair. Leafy greens like spinach, kale, and parsley are rich in chlorophyll, which may help protect collagen fibers from damage while boosting your body’s natural regenerative processes. Dr. Liu highlights that incorporating chlorophyll-rich foods adds a nutrient-dense boost to your diet, complementing other collagen-supporting nutrients.
Collagen production isn’t just about topical treatments—it’s built from the inside out. By incorporating these collagen-boosting nutrients into your diet, you can support skin health, immunity, and overall vitality. While whole foods are the best source, supplements can complement your routine, helping you achieve strong, radiant, and youthful skin.
