Vitamin E, including its gamma tocopherol form, has been studied for its potential benefit in supporting and treating eczema (atopic dermatitis), but the evidence remains limited. Some small clinical trials and observational studies suggest that oral or topical vitamin E supplementation may improve symptoms such as itching, redness, and severity of lesions. The rationale is based on vitamin E’s antioxidant and anti-inflammatory properties, which may help reduce oxidative stress and inflammation implicated in eczema pathogenesis.

However, most clinical studies use alpha-tocopherol rather than gamma-tocopherol, and often involve small sample sizes, short durations, or combination therapies with other antioxidants or vitamins. A 2015 randomized controlled trial found that oral vitamin E (400 IU/day) for 8 months led to significant improvement in eczema severity compared to placebo, but this and similar studies generally lack robust replication. There is also some evidence supporting topical vitamin E in reducing symptoms, but again, studies are small and results are mixed.

In summary, there is some scientific rationale and preliminary evidence for vitamin E’s benefit in eczema, but the overall quality and quantity of evidence is low. More large, well-designed clinical trials are needed to confirm efficacy, clarify the optimal form and dose, and determine safety, especially for long-term use. Thus, scientific support exists but is currently weak (evidence rating: 2/5).
