Dietary Supplements for UV Protection

Last updated: January-20,2023

What Are the Best Dietary Supplement Ingredients for UV Protection

Exposure to UV rays (whether those rays are from the sun or artificial sources like tanning beds) can cause premature aging of the skin (photoaging) and signs of sun damage such as wrinkles, leathery skin, liver/age spots, as well as rough and scaly skin patches.[i]The good news is that there are dietary supplements that can protect against UV rays, and/or help mitigate some of the effects of UV exposure. This includes niacinamide, grape seed extract, red orange complex, beta-carotene, EPA, and pomegranate extract.

Niacinamide

A randomized, double-blind, placebo-controlled trial,[ii] and a case-control study were undertaken to examine the effects of 500 mg/day niacinamide on photoaging.[iii] Results were that niacinamide had photoprotective effects and helped reduce rough, scaly skin patches caused by long-term sun exposure. Additionally, a key type of immunity known as cutaneous immunity is suppressed by even small doses of UV rays. Another randomized, double-blinded, crossover study found that supplementation with 1500 or 500 mg/day of niacinamide significantly reduced UV immunosuppression.[iv] Niacinamide’s potential to reduce rough, scaly skin patches, and UV immunosuppression makes it a good ingredient for supplements to prevent sun damage.

Grape seed extract

Grape seed extract is another great UV protection supplement. It contains a powerful antioxidant known as proanthocyanidin. In a one-year open design study, a proanthocyanidin-rich grape seed extract (GSE) was orally administered (76 mg (54 mg of proanthocyanidin) three times a day) in women with skin hyperpigmentation (which may often be due to UV overexposure). Results were that GSE was effective in reducing hyperpigmentation (in 83% of women) and preventing it from getting worse before the summer season.[v]

Red orange complex

Hyperpigmented lesions, also known as age spots, are one of the most visible alterations in skin photoaging. A study was performed to evaluate the skin photoprotective and anti-aging effects of 100 mg/day supplementation with a red orange extract (red orange complex) supplementation.[vi] Results were that the red orange complex helped reduce UV-induced age spots and skin redness. Skin age spot pigmentation (melanin content) decreased from 27% to 7% when subjects were exposed to a solar lamp during red orange extract supplementation. In another randomized, double-blind, controlled study , 100 mg/day of red orange complex improved the skin’s antioxidant capacity and reaction to UV exposure, increased moisturization and elasticity, and decreased the intensity of melanin staining inside skin dark spots, transepidermal water loss (TEWL) and wrinkle depth.[vii]

Beta-carotene

A UV protection supplement that brand owners must know about is Beta-carotene. It is an effective antioxidant and can be converted to vitamin A in the body. The purpose of this study was to determine the effects of 2 different doses of beta-carotene (30 and 90 mg/day) on wrinkles and elasticity, procollagen gene expression, and ultraviolet (UV)-induced DNA damage in human skin.[viii] Results showed that beta-carotene improved facial wrinkles and elasticity significantly only in the low-dose group. Type I procollagen mRNA levels were significantly increased only in the low-dose group, and UV-induced DNA damage was reduced in the low-dose group. In short, 30 mg/day of beta-carotene supplementation was demonstrated to help prevent and repair photoaging.

Best Dietary Supplements for UV Protection

EPA

The importance of omega-3 fatty acids in human health and wellness is well-established. Omega-3s include α-linolenic (ALA), eicosapentaenoic (EPA), docosapentaenoic (DPA), and docosahexaenoic acids (DHA). A cross-sectional study was conducted on 2,919 subjects aged 45-60 years to investigate associations between daily omega-3 intake and the severity of skin photoaging.[ix] Results showed that after adjustment for possible confounders, severe photoaging was found to be decreased with a higher intake of EPA in women. A significant decrease in photoaging risk was found in women with higher intakes of EPA. The highest intake level (95 percentile) of EPA was 295 mg/day. Likewise, extremely high doses of EPA (about 2-4 grams/day) were also shown to decrease photoaging.[x] [xi] [xii] [xiii]

Pomegranate extract

Pomegranate extract is another source of powerful antioxidants, including ellagic acid. A double-blind, placebo-controlled trial was conducted to evaluate the protective and ameliorative effects of ellagic acid-rich pomegranate extract on skin pigmentation UV irradiation in female subjects assigned to three groups: high dose (200 mg/d ellagic acid), low dose (100 mg/d ellagic acid) and control (0 mg/d ellagic acid: placebo).[xiv] Luminance (L), melanin, and erythema (skin reddening) values were measured before the start of supplementation, and after 1, 2, 3, and 4 weeks. Results were decreasing rates of L values in the low- and high-dose groups, with inhibition by 1.35% and 1.73% respectively, as compared to the control group. Subjects with a slight sunburn revealed an inhibited decrease of L values compared with the control group at 1, 2, and 4 weeks in the low-dose group, and at 2 and 3 weeks in the high-dose group. Furthermore, the results of questionnaires showed ameliorating tendencies with pomegranate extract in “brightness of the face” and “stains and freckles.” In conclusion, ellagic acid-rich pomegranate extract has an inhibitory effect on a slight pigmentation in the human skin caused by UV irradiation, making it a terrific nutraceutical to include in your UV protection supplements.

Conclusion

Exposure to UV rays can cause premature aging of the skin (photoaging). Niacinamide, grape seed extract, red orange complex, beta-carotene, EPA, and pomegranate extract are dietary supplements that can protect against UV rays, and/or help mitigate some of the effects of UV exposure.
