1. Fish oil
Fish oil helps boost your intake of heart-healthy omega-3 fatty acids, which may support skin health due to their powerful anti-inflammatory properties.
There is some evidence that these fatty acids can suppress the activity of immune cells that trigger eczema.
While research results have been mixed, several studies have found a link between fish oil supplements and improved eczema symptoms.
Summary
Although more research is needed, some animal and human studies suggest that fish oil may be beneficial for treating eczema.
2. Vitamin D
Your skin produces vitamin D — also known as the sunshine vitamin — when exposed to the sun. Vitamin D is also found naturally in several foods and is widely available as a supplement.
Some research suggests that vitamin D may help treat eczema.
One review of four studies concluded that supplementing with vitamin D was more effective at reducing the severity of eczema symptoms than placebo treatment.
Another review of 21 studies associated lower vitamin D levels with increased eczema severity in children. It also found that supplementing with vitamin D improved eczema symptoms in about two-thirds of the studies.
Summary
Multiple studies suggest that supplementing with vitamin D may reduce inflammation and symptoms of eczema.
3. Vitamin E
Vitamin E is an essential micronutrient in various skin care products.
In addition to its ability to protect the skin against oxidative stress, some studies have found that it may help decrease symptoms of eczema.
A recent review has also concluded that a daily dosage of up to 600 IU of vitamin E is considered safe and may benefit skin health.
Summary
Supplementing with vitamin E may help improve skin health and decrease symptoms of eczema.
4. Zinc
Zinc is an important mineral that plays a key role in skin health.
Several studies suggest it may help treat inflammatory skin conditions, including acne and eczema.
One review of 16 studies also associated low zinc levels with a higher chance of eczema (19).
Keep in mind that zinc is found in many food sources, including meat, seafood, dairy, and legumes, and most people can meet their needs by following a healthy, well-rounded diet.
However, if you think you might have a deficiency, talk with a doctor to see whether supplementation may be beneficial.
Summary
Some studies show that supplementing with zinc may help reduce eczema severity, especially if you have a deficiency.
5. Melatonin
Although melatonin is best known as a sleep supplement, it may also help treat eczema.
Research shows that melatonin may act as an antioxidant, reduce levels of specific inflammation markers, and inhibit eczema development.
One study included 48 children. Taking 3 mg of melatonin daily for 4 weeks improved sleep quality and reduced eczema severity.
However, further studies are needed, especially in adults.
Summary
Melatonin may act as an antioxidant and reduce levels of inflammation. Some research suggests that it may decrease eczema severity in children, but more studies are needed.
6. Probiotics
Probiotics are beneficial bacteria associated with numerous health benefits.
Although research has found mixed results, some studies suggest that probiotics may help reduce symptoms of eczema.
For instance, one study showed that infants who received probiotics were less likely to develop eczema than those in a control group.
On the other hand, one review of 39 studies concluded that probiotics didn’t significantly affect symptoms or quality of life in people with eczema.
Therefore, more research is needed to determine whether probiotics are beneficial for treating eczema.
summary
Some studies show that probiotics may help treat and prevent eczema, but research is conflicting.
