Source of validity: Scientific
Rating (out of 5): 3

Vitamin E, particularly in the form of alpha tocopheryl succinate, has some scientific support for its role in supporting capillary health, primarily due to its antioxidant properties. Vitamin E is known to protect cell membranes from oxidative damage, which is a significant factor in the maintenance of vascular integrity, including that of capillaries. Several studies have indicated that vitamin E supplementation can reduce lipid peroxidation and help maintain endothelial function, potentially contributing to the resilience of small blood vessels and capillaries (source).

However, while the general antioxidant action of vitamin E is well documented, direct clinical evidence specifically linking alpha tocopheryl succinate to improved capillary function in humans is limited. Some animal studies and in vitro experiments suggest that vitamin E can prevent capillary fragility and reduce inflammation associated with vascular damage (source). Additionally, vitamin E deficiency is associated with increased capillary permeability and fragility in both animal and human studies, further supporting its importance in capillary health.

Overall, while there is a plausible scientific rationale and some supportive evidence for vitamin E’s role in supporting capillary health, the strength of clinical data is moderate and not conclusive. Thus, the evidence rating is 3 out of 5.
