Vitamin E (alpha-tocopherol) protects cell membranes from oxidative damage and supports nerve, muscle, eye, and immune health. While deficiency is uncommon in healthy adults, it can occur with fat-malabsorption disorders, very low-fat diets, certain genetic conditions, and in people with chronic liver or pancreatic disease. Recognizing early warning signs helps you seek evaluation before long-term damage occurs.

Who is genuinely at risk?
Vitamin E requires dietary fat for absorption. Deficiency risk is higher in adults with conditions that impair fat absorption (e.g., Crohn’s disease, celiac disease, chronic pancreatitis, cystic fibrosis), in those with cholestatic liver disease, after extensive small-bowel surgery, or with rare genetic disorders affecting lipoprotein formation or vitamin E transport. Strict very low-fat diets and prolonged, unbalanced restrictive eating patterns can also contribute.
The 10 symptoms you should not ignore
- Muscle weakness (myopathy) - Damage to muscle cell membranes can reduce strength and endurance, with heavier, sore muscles after ordinary activity.
- Tingling, numbness, or burning in hands/feet (peripheral neuropathy) - Sensory changes often start distally and may progress proximally.
- Unsteady gait or poor balance (ataxia) - Clumsiness, frequent stumbling, or difficulty on uneven surfaces due to cerebellar and posterior column involvement.
- Vision problems - Blurred or dim vision, night-vision difficulty, or progressive retinal changes (retinopathy) in longer-standing deficiency.
- Weak or depressed reflexes (hyporeflexia) - Knee/ankle jerks may be reduced as neuropathy advances.
- Tremors or muscle twitching - Small, coarse shakes in the hands or eyelids; fasciculations can occur with neuromuscular involvement.
- Difficulty with fine motor tasks - Buttons, writing, suturing, or typing may feel less precise because of proprioceptive deficits.
- Immune vulnerability - More frequent infections or slower recovery due to impaired immune responses.
- Skin and hair issues - Dry, fragile skin and hair thinning may appear (multifactorial, but worsened by deficiency).
- Rare severe features - With prolonged untreated deficiency: visual field loss, significant coordination problems, and (rarely) cardiac rhythm issues reported in advanced cases.
When to act (quick guide)
| Scenario | What you can do now | Seek medical care if |
|---|---|---|
| Mild new tingling, occasional muscle cramps | Review diet quality; add nuts/seeds/greens; avoid ultra-low-fat eating | Symptoms persist 2–4 weeks or worsen |
| Unsteady gait, dropping objects, reduced reflexes | Stop any self-started high-dose supplements; keep a symptom diary | Immediate - request exam and blood tests (tocopherol levels) |
| Known fat-malabsorption disorder | Discuss routine monitoring and targeted supplementation with your doctor | Any neurological or visual symptoms appear |
How much Vitamin E do adults need?
The Recommended Dietary Allowance (RDA) for adults is 15 mg/day (22 IU) alpha-tocopherol. Most people can meet this through food. Excessive supplemental dosing can increase bleeding risk and, at very high doses, cause serious harm.
Who should get tested?
Testing (serum alpha-tocopherol, sometimes lipid-adjusted) is reasonable if you have compatible symptoms plus risk factors such as fat-malabsorption, cholestatic liver disease, prolonged unbalanced restrictive diets, or certain genetic conditions (e.g., abetalipoproteinemia, AVED). Your clinician may also check a neurological exam (vibration sense, reflexes, gait) and eye evaluation if vision changes are present.
Safety note on supplements
Do not self-start high-dose Vitamin E. Upper limits vary by form, and excess intake can increase bleeding risk. Always discuss with your doctor, especially if you take anticoagulants, antiplatelets, or have bleeding disorders.
