8 Best Vitamins and Supplements for Dry Skin
Depending on the cause of your dry skin, different treatment methods, including medicated ointments and moisturizers, may be used to increase skin hydration.
Additionally, lifestyle modifications, such as drinking more water and taking certain supplements, may improve skin dryness.
Here are 8 vitamins and supplements for dry skin.
1. Vitamin D
Vitamin D is a fat-soluble vitamin that's critical for many aspects of health, including the health of your skin.
Keratinocytes are skin cells that make up the majority of the outer layer of your skin, known as the epidermis.
What's more, research has indicated a correlation between vitamin D and skin moisture.
A study in 83 women found that those who had low vitamin D levels had lower average skin moisture than participants who had normal vitamin D levels, and that as blood levels of vitamin D increased, skin moisture content increased as well.
Another small 12-week study in 50 women observed that daily treatment with a nutritional supplement containing 600 IU of vitamin D led to significant improvements in skin hydration.
However, the supplement contained a combination of nutrients, so it's unclear whether treatment with vitamin D alone would have resulted in the same positive outcome.
A large percentage of the population is deficient in vitamin D, and given that the nutrient is essential for skin hydration, supplementing with it may help combat dry skin.
Vitamin D supplements are widely available in stores and online.
Be sure to discuss their use with your healthcare provider first and look for products that have been third-party tested to ensure the highest quality.
Research shows that low levels of vitamin D may increase the chances of dry skin. Therefore, supplementing with this nutrient may help increase skin hydration.
Collagen is the most abundant protein in your body and accounts for 75% of your skin's dry weight.
Some research has shown that taking collagen-based supplements may have a range of benefits for your skin, including decreasing wrinkle depth and increasing skin hydration.
A study in 69 women found that participants who consumed 2.5–5 grams of collagen per day for 8 weeks had significant improvements in skin elasticity and also experienced increased skin hydration, compared with a placebo group.
Another 12-week study in 72 women noted that taking a supplement that contained 2.5 grams of collagen peptides along with a blend of other ingredients like vitamin C and zinc significantly improved skin hydration and roughness, compared with a placebo group.
However, the supplement contained other nutrients, so it's unknown whether collagen alone would have had the same effects.
Plus, the study was funded by the supplement manufacturer which may have affected the study results.
If you want to try a collagen supplement to help with your dry skin, speak with your healthcare provider before purchasing a third-party certified product locally or online.
A good amount of evidence supports the use of collagen supplements for increasing skin hydration and treating dry skin.
3. Vitamin C
In fact, the skin contains very high levels of vitamin C, with some research finding a concentration of up to 64 mg of vitamin C per 100 grams of the epidermal skin layer.
Unsurprisingly, studies have shown that increasing dietary vitamin C through vitamin C supplements may improve many factors of skin health, including skin hydration.
Plus, some studies have shown that when used in combination with other nutrients, vitamin C may help enhance skin moisture.
For example, a 6-month study in 47 men demonstrated that taking a supplement that contained 54 mg of vitamin C, as well as marine protein and a combination of other nutrients, significantly improved skin hydration, compared with a placebo group.
Other studies in women have shown similar results.
A study in 152 women found that participants who took a supplement that contained 54 mg of vitamin C, as well as zinc and marine protein, had significantly reduced skin roughness, compared with a placebo group.
However, in most of the available research on vitamin C's effect on dry skin, vitamin C is combined with other nutrients, making it impossible to tell whether the nutrient would have the same effect if it was used on its own.
Plus, many of the studies were sponsored by the pharmaceutical companies that manufactured the product being evaluated, which may have affected study results.
Regardless, based on the most current research, supplementing with vitamin C may improve overall skin health and help combat dry skin.
As with any new supplement, you should speak with a healthcare professional before adding a vitamin C supplement to your diet. These products are widely available in stores and online.
Vitamin C is an integral nutrient for skin health. Consuming supplemental vitamin C may improve dry skin, according to some studies. However, more research on its effects on dry skin is needed.
4. Fish Oil
Fish oil is well known for its skin-health-promoting properties.
It contains docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), two essential fatty acids that have powerful anti-inflammatory and healing properties and have been shown to benefit the skin in many ways.
Dietary supplements with fish oil may help boost skin hydration and improve the fatty acid barrier of the skin, which helps maintain hydration.
A 90-day study in rats with acetone-induced dry skin found that high-dose oral fish oil supplements significantly increased skin hydration, reduced water loss, and resolved dryness-related skin itching, compared with rats that didn't receive the fish oil.
In fact, the study noted that the fish oil group had a 30% increase in skin hydration after 60 days of treatment.
Additionally, research indicates that daily treatment with doses of fish oil ranging from 1–14 grams of EPA and 0–9 grams DHA for 6 weeks to 6 months improved symptoms of psoriasis — a chronic, inflammatory skin disease — including scaling or dry, cracked skin.
Fish oil has also been shown to decrease skin inflammation and protect against sun damage, making it an all around skin-friendly supplement.
There are many great, third-party-certified fish oil products available in stores and online. Speak with your healthcare provider first to determine the best choice and dosage for your needs.
Fish oil may help improve skin hydration and decrease moisture loss. Plus, it has been shown to improve dry, scaling skin in those with psoriasis.
5–8. Other Supplements for Treating Dry Skin
In addition to the nutrients listed above, studies have shown that supplementing with several other compounds may be an effective way to improve skin moisture.
- Probiotics. A study found that supplementing both mice and humans with Lactobacillus plantarum bacteria improved skin barrier function and skin hydration after 8 weeks. However, more research is needed.
- Hyaluronic acid. Hyaluronic acid is often used topically to improve skin hydration, but recent research shows that ingesting this compound in combination with other nutrients may significantly increase skin hydration.
- Aloe vera. A study in 64 women found that supplementing with fatty acids derived from aloe vera for 12 weeks significantly improved skin moisture and skin elasticity, compared with a placebo.
- Ceramides. Ceramides are fat molecules that are important components of healthy skin. Some research has shown that supplementing with ceramides may increase skin hydration, which may help treat dry skin.
Some research suggests that the supplements listed above may help enhance skin moisture and treat dry skin.
However, more research is needed before these compounds can be recommended as effective ways to naturally relieve dry skin.
Supplementing with probiotics, hyaluronic acid, aloe vera extracts, and ceramides may improve dry skin, but more research is needed.
Although taking certain supplements may help improve dry skin, several other factors can contribute to skin dryness and should be considered.
For example, dehydration is a common cause of dry skin, so upping your water intake can be a healthy and easy way to improve skin hydration.
Following an unhealthy diet, having micronutrient deficiencies, and not eating enough may also cause or worsen dry skin.
Therefore, it's important to talk to your healthcare provider if you're experiencing significantly dry, irritated skin to rule out more serious health conditions.
Dry skin can be a sign of an underlying health condition, so it's important to contact your healthcare provider if you have unexplained, significantly dry skin.
The Bottom Line
Dry skin is a common condition that can be caused by a number of factors, such as dehydration, allergic reactions, and diseases like hypothyroidism.
Research has shown that taking certain vitamins and other nutritional supplements, including vitamin D, fish oil, collagen, and vitamin C, may help improve skin hydration and help keep your skin healthy and nourished.
However, although the supplements on this list may act as helpful tools for people who have dry skin, it's important to talk to your healthcare provider if you're experiencing unexplained, chronic dry skin, as this can be a sign of an underlying medical condition.

Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.
Comparing rime ice and glaze ice shows how each changes the texture of the blade. Gao, Liu and Hu, 2021, CC BY-ND
Ice buildup changes air flow around the turbine blade, which can slow it down. The top photos show ice forming after 10 minutes at different temperatures in the Wind Research Tunnel.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
