Vitamin E (alpha-tocopherol): what your result means.

A fat-soluble antioxidant that protects cell membranes from oxidative damage. Vitamin E (alpha-tocopherol) is measured by blood test as part of the Nutritional panel in the HodieLabs Health Blueprint.

Why Vitamin E (alpha-tocopherol) matters

Vitamin E is lipid-soluble and transported in LDL/HDL, elevated lipids falsely elevate vitamin E. Lipid-adjusted vitamin E (alpha-tocopherol/total cholesterol ratio) is more accurate.

Associated risks when out of range: Deficiency causes peripheral neuropathy, ataxia, and impaired immune function, High-dose supplementation (>400 IU/day) may paradoxically increase all-cause mortality.

What the clinical evidence shows

The evidence base behind how the HodieLabs Evidence-Based Clinical Library interprets Vitamin E (alpha-tocopherol), from randomised trials, prospective cohorts and genetic (Mendelian randomisation) studies. Full citations in the reference list below.

• HOPE trial (Yusuf et al. NEJM 2000): vitamin E supplementation in ~9,500 high-risk adults produced no cardiovascular benefit over 4.5 years, a landmark null result showing antioxidant supplementation is not a shortcut to vascular protection.
• SELECT trial (Lippman et al. JAMA 2009): vitamin E did not prevent prostate cancer in ~35,000 men, reinforcing that measured sufficiency, not supra-supplementation, is the evidence-based goal.

Evidence-based reference ranges

The HodieLabs Evidence-Based Clinical Library interprets Vitamin E (alpha-tocopherol) against published clinical authority standards, never arbitrary "optimal" ranges. Measured in µmol/L:

Clinical interpretation

• Vitamin E is lipid-soluble and transported in LDL/HDL, elevated lipids falsely elevate vitamin E.
• Lipid-adjusted vitamin E (alpha-tocopherol/total cholesterol ratio) is more accurate.
• High-dose supplementation may interfere with vitamin K metabolism and increase bleeding risk.

What improves it: the evidence-based levers

• Food sources (nuts, seeds, vegetable oils) are preferred over supplements
• Interpret alongside lipid levels. Vitamin E is transported in lipoproteins

Recommended testing frequency: Annual, as part of a comprehensive panel. Single markers are always interpreted in context.

How Vitamin E (alpha-tocopherol) testing works at HodieLabs

Vitamin E (alpha-tocopherol) is measured in every Health Blueprint at our Melbourne Preventative Health & Longevity Clinic, interpreted by a doctor against the guideline-cited ranges above and tracked over time through your HodieLabs membership.
