When it comes to maintaining a healthy, clear complexion, what we put in our bodies matters just as much as what we put on our faces. Many factors can lead to blemish-prone skin (think: hormones, genetics, hygiene), but one element that is in our control is nutrition. Eating a varied diet that is rich in skin-nourishing vitamins is important, but sometimes we might need a little extra help from supplements. It's important to note, though, that supplements should always be used in addition to a robust diet and should not take the place of consuming nutrients from food—and, as always, be sure to consult your medical provider before trying a new supplement.

What to Look For in a Vitamin for Clear Skin
When it comes to using vitamins to treat acne, Dr. Garshick recommends reaching for vitamin A. “It’s known that vitamin A derivatives, also known as retinoids, help to clear acne as they help to regulate skin cell turnover, which helps prevent pores from clogging,” she says. “Retinoids also work to stimulate collagen production, which can improve the appearance of scarring related to acne as well. At the molecular level, retinoic acid diffuses through the cell membrane and binds to nuclear receptors to promote cell turnover.” While isotretinoin (also known as Accutane) is available via a doctor's prescription, lower-dose formulas are available over the counter. It's also important to note that it's a fat-soluble vitamin and that hypervitaminosis A can occur with too much vitamin A.
According to Dr. Garshick, vitamin B3 is another must. “A form of vitamin B3 or niacin, called nicotinamide, may be helpful in the treatment of acne through its anti-inflammatory effects,” she says. “It also may be effective at reducing oil production, which leads to shine and oiliness. Both topical and oral supplements have been studied and have shown improvement in acne.”
Dr. Garshick also recommends looking into zinc, though the overall verdict is mixed. “There is some evidence to show that lower levels of zinc can be associated with more severe acne, suggesting that zinc supplementation should help acne,” she says. adding that it’s been shown that supplementing zinc in those who are lacking it can help to improve acne.
However, there are some side effects. “When taken in high doses, zinc also causes some nausea, vomiting, and diarrhea, causing some patients to stop taking it,” she says. “There are different formulations of zinc available, so if you’re interested in taking a zinc supplement to treat your acne, be sure to check with a medical specialist first to ensure you’re taking the proper dose. Given its role in fighting bacteria and increasing concern for antibiotic resistance, further research needs to be done to determine the best dose and type of zinc that’s most effective for the treatment of acne.”
Of course, as mentioned earlier, Dr. Garshick says it will take time to see any improvement when using vitamins to help clear your complexion, so patience is key. “We usually recommend giving most treatments for acne approximately two to three months before determining if it is effective or not,” she says.
Supplements are not regulated by any governing body so it is important to prioritize products that feature certified ingredients and seals of approval. Some common certifications include NSF gluten-free, non-GMO project verified, certified vegan, and certified glyphosate residue-free. In addition to specific ingredient-focused certifications, some products have been verified by third-party testing sites like Labdoor or ConsumerLabs. These independent companies verify that what is in the bottle matches what is on the label.

Vitamin E is an important fat-soluble vitamin and works as an antioxidant. Most commonly found in nuts and seeds, supplementing with vitamin E may be helpful for those with limited diets. However, it's important to note that many supplements provide much more than the recommended daily intake of vitamin E; many provide close to or more than the tolerable upper limit for vitamin E (1,000 milligrams). For this reason, NOW Food’s wheat germ oil is our top pick for supplements containing vitamin E. One tablespoon provides 20 milligrams of vitamin E and buyers can decide to adjust the amount based on their needs.

Garden of Life Dr. Formulated Platinum Series Skin+ supplement provides 90 Billion CFU of 12 bacterial strains, as well as vitamin A and lycopene. We love that the serving size is one capsule and each capsule features two clinically studied strains: L. Johnsonii la-1 and L. Paracasei st-11.

How do vitamins for clear skin work?
Certain vitamins may help promote clearer skin for some people. However, the ways that specific vitamins and minerals aid in doing this is still unclear. One 2013 study found that participants with acne had significantly lower amounts of vitamin A and E, as well as the mineral zinc, compared to those without acne. Continued research needs to be done to explain if and how certain vitamins work to clear skin.
How often should you take vitamins for clear skin?
The frequency of supplement use depends on the individual and the supplement. If you're deficient in a specific vitamin, it might be necessary to take supplements daily for a few months at least. Additionally, it might take a while to see a difference in your skin—usually, the best results will occur when you can be consistent and take supplements daily. As always, follow directions from your doctor or health care provider.
