Bio-E-Vitamin — Natural Vitamin E for Cellular Antioxidant Defence Bio-E-Vitamin delivers natural d-alpha-tocopherol — the most biologically active form of Vitamin E — in a pharmaceutical-grade soft-gel capsule. As the body's primary fat-soluble antioxidant, Vitamin E is embedded within cell membranes where it neutralises free radicals before they can damage lipid structures, proteins, and DNA. This EU-authorised health claim is supported by decades of peer-reviewed research. Food supplement. Not intended to diagnose, treat, cure, or prevent any disease. Ingredients d-alpha-Tocopherol (Natural Vitamin E) — sourced from non-GMO vegetable oils; the RRR-stereoisomer with approximately 36% greater bioavailability than synthetic dl-alpha-tocopherol (Acuff et al., American Journal of Clinical Nutrition, 1994) Carrier oil — high-oleic sunflower oil (supports lipid-phase absorption) Capsule shell — bovine gelatine, glycerol, purified water No artificial colours, flavours, or preservatives Benefits — Clinical Research Overview 1. Antioxidant Protection Against Oxidative Stress ✓ EU-Authorised Health Claim Vitamin E is the principal chain-breaking antioxidant in biological membranes. It donates a hydrogen atom to lipid peroxyl radicals, halting the propagation of lipid peroxidation. A landmark meta-analysis by Traber & Atkinson (Free Radical Biology & Medicine, 2007) confirmed that d-alpha-tocopherol is the predominant form retained in human plasma and tissues, with preferential binding to alpha-tocopherol transfer protein (α-TTP) in the liver. 2. Cardiovascular Health Support The CHAOS trial (Cambridge Heart Antioxidant Study, The Lancet, 1996; Stephens et al.) demonstrated a significant reduction in non-fatal myocardial infarction in patients with coronary atherosclerosis supplementing with natural-source Vitamin E (400–800 IU/day). Mechanistically, Vitamin E inhibits LDL oxidation — a key initiating step in atherogenesis — as documented by Esterbauer et al. (Free Radical Biology & Medicine, 1992). 3. Immune Function A randomised controlled trial by Meydani et al. (JAMA, 1997) found that Vitamin E supplementation (200 mg/day) significantly enhanced cell-mediated immunity in healthy elderly subjects, increasing delayed-type hypersensitivity skin responses and antibody titres to hepatitis B and tetanus vaccines. Vitamin E modulates T-cell signalling by reducing prostaglandin E₂ production via inhibition of cyclooxygenase-2 (COX-2). 4. Skin Integrity & Photoprotection Vitamin E accumulates in the stratum corneum and sebum, providing a first line of defence against UV-induced oxidative damage. Fuchs & Kern (Free Radical Biology & Medicine, 1998) demonstrated that topical and oral Vitamin E reduces UV-induced lipid peroxidation and erythema. Synergistic effects with Vitamin C have been documented by Eberlein-König et al. (Journal of the American Academy of Dermatology, 1998). 5. Neuroprotection Observational data from the Cache County Study (Archives of Neurology, 2004; Zandi et al.) found that combined Vitamin E and C supplementation was associated with reduced prevalence and incidence of Alzheimer's disease. Vitamin E's role in protecting neuronal membranes from peroxidative damage is supported by Butterfield et al. (Nutritional Neuroscience, 2002). 6. Reproductive & Hormonal Health Vitamin E's original designation as the "anti-sterility vitamin" (Evans & Bishop, Science, 1922) reflects its role in reproductive tissue protection. More recently, Moslemi & Tavanbakhsh (International Journal of General Medicine, 2011) reported improved sperm motility and morphology with Vitamin E and selenium co-supplementation in infertile men. 7. Who May Benefit Most Individuals on low-fat diets (reduced dietary Vitamin E intake) Smokers and those with high environmental pollutant exposure (elevated free radical burden) Older adults (age-related decline in antioxidant capacity) Those with high polyunsaturated fatty acid (PUFA) intake (increased oxidative demand) Individuals with malabsorption conditions (e.g., Crohn's disease, cystic fibrosis) Suggested Use Take as directed on the label or as advised by a qualified healthcare practitioner. Vitamin E is fat-soluble — take with a meal containing dietary fat for optimal absorption. Regulatory Notice The health claim "Vitamin E contributes to the protection of cells from oxidative stress" is authorised under EU Regulation No 432/2012 and retained in Great Britain post-Brexit.
