Rating (out of 5): 2

Vitamin E, specifically in the forms of beta and delta tocopherols, has been investigated for its potential benefits in treating or supporting eczema (atopic dermatitis) primarily due to its antioxidant and anti-inflammatory properties. Several clinical studies have evaluated the effects of oral and topical Vitamin E (usually mixed tocopherols) in patients with eczema. Some small randomized controlled trials and observational studies have reported improvements in eczema severity scores and reductions in symptoms like itching and erythema when Vitamin E is used, either alone or in combination with other therapies. The proposed mechanisms include the reduction of oxidative stress in the skin and modulation of inflammatory responses, both of which are implicated in eczema pathophysiology.

However, the bulk of available research uses alpha-tocopherol, the most common and bioactive form of Vitamin E, rather than specifically beta or delta tocopherols. Evidence directly supporting beta and delta tocopherols is limited and mostly extrapolated from broader studies on Vitamin E. The overall quality of the evidence is low to moderate due to small sample sizes, short intervention periods, and heterogeneity in study design. Most systematic reviews and dermatology guidelines conclude that while there may be some benefit, Vitamin E should not replace established therapies but can be considered as an adjunct in some cases.

In summary, there is scientific investigation into Vitamin E’s role in eczema, but specific evidence for beta and delta tocopherols is weak, and the overall evidence base rates as low (2/5) in terms of strength and consistency.
