Vitamin E Deficiency Test: Check Your Symptoms Online

Based on NIH Office of Dietary Supplements guidance · Last reviewed: July 15, 2026 · How we source our content

Vitamin E is unusual among the nutrients we screen for: it's genuinely rare to become deficient from diet alone, because it's present in enough common fats and oils that most people get plenty without trying. When deficiency does happen, it's almost always because something is preventing absorption — which makes it a different kind of question than "am I eating enough."

Muscle weakness, coordination or vision problems?

Our free assessment weighs your symptoms and risk factors in about 2 minutes.

Why the symptoms are neurological

Vitamin E is a fat-soluble antioxidant that protects nerve cell membranes from damage. Deficiency symptoms reflect that role directly, and they tend to develop gradually over a long period rather than appearing suddenly:

  • Muscle weakness
  • Loss of coordination and balance (ataxia) — a hallmark of more established deficiency
  • Vision problems — from retinal nerve involvement
  • Numbness or tingling — nerve damage similar in feel to B12 deficiency, but from a different mechanism
  • Weakened immune response

Who's actually at risk

Unlike most nutrients on this site, diet choice alone rarely explains vitamin E deficiency. The risk factors are almost entirely medical:

Fat-malabsorption conditions

Crohn's disease, celiac disease, cystic fibrosis and chronic pancreatitis all significantly impair vitamin E absorption.

Rare genetic disorders

Conditions like abetalipoproteinemia directly impair the body's ability to transport vitamin E, even with normal intake.

Premature infants

Low birth reserves and immature fat absorption put premature infants at higher risk — a pediatric, not adult, concern.

Very low-fat diets, long-term

Since vitamin E requires dietary fat for absorption, an extended very-low-fat diet can contribute, though this alone rarely causes clinical deficiency.

Where our test fits

Given how rare dietary vitamin E deficiency is, our free assessment weighs it mainly through your digestive health history rather than diet alone — and checks whether nerve-related symptoms like tingling or coordination problems might better fit B12 deficiency, which is far more common and produces similar sensory symptoms through a different mechanism.

If you are low

Sunflower seeds, almonds, wheat germ oil, and spinach are among the best sources. Adults need 15 mg/day. If deficiency stems from a malabsorption condition rather than diet, food sources alone often aren't enough — treatment typically requires medically supervised, higher-dose supplementation, which is a conversation for your doctor rather than something to self-manage with an over-the-counter product.

Frequently asked questions

Dietary deficiency from food alone is very rare in healthy adults, since vitamin E is present in many common fats and oils. True deficiency almost always results from an underlying fat-malabsorption condition rather than diet choices.

Vitamin E is a fat-soluble antioxidant that protects nerve cell membranes from oxidative damage. Without it, peripheral nerves and spinal sensory pathways degrade over time, producing coordination and sensory problems in established deficiency.

Yes. High-dose vitamin E has mild blood-thinning properties and can increase bleeding risk when combined with anticoagulants like warfarin. Anyone on blood thinners should talk to their doctor before supplementing.

When caught and treated early, yes — supplementation, often at medically supervised higher doses for malabsorption-related deficiency, typically improves symptoms. Nerve damage from prolonged, severe deficiency may not fully reverse.
