Vitamin E: Daily supplementation with oral vitamin E may be beneficial for respiratory infection prevention. Additional research is warranted.
Caution is advised when taking vitamin E supplements, as adverse effects and drug interactions are possible. Avoid if allergic or hypersensitive to vitamin E. Avoid with retinitis pigmentosa (loss of peripheral vision). Avoid if pregnant or breastfeeding, unless otherwise directed by a doctor. Use cautiously with bleeding disorders or if taking blood thinners.
