What Is Vitamin E and Why Does It Matter?
Vitamin E is a group of fat-soluble compounds with distinct antioxidant properties. Amongst these, alpha-tocopherol is the most biologically active form and the one maintained in human plasma. This nutrient plays a role in protecting cells from oxidative stress, which is a natural process linked to ageing and overall cellular health. Vitamin E also contributes to normal immune function and helps maintain healthy skin by supporting the skin's barrier function.
Because the body does not produce vitamin E, it must come from dietary sources or supplementation. While food sources like nuts, seeds, and leafy greens provide vitamin E, many people choose a supplement to ensure consistent intake. NOW Foods Vitamin E 400 IU softgels deliver natural d-alpha-tocopherol, the form preferentially recognised by the body.
Benefits of Vitamin E Supplements
Vitamin E supplementation is associated with several potential benefits, though individual results can vary. As an antioxidant, vitamin E may help neutralise free radicals, which are unstable molecules that can damage cells. This antioxidant action is one reason vitamin E is often highlighted for skin health—helping to protect skin from environmental stressors and supporting a youthful appearance.
Immune function is another area where vitamin E may contribute. Adequate intake of vitamin E supports the normal function of the immune system, particularly in older adults. Additionally, vitamin E is involved in cell signalling and may help maintain healthy blood vessels by supporting normal circulation.

Natural vs. Synthetic Vitamin E – What's the Difference?
Vitamin E supplements come in two main forms: natural (d-alpha-tocopherol) and synthetic (dl-alpha-tocopherol). The difference matters because the body absorbs and retains natural vitamin E nearly twice as effectively as synthetic forms. Natural vitamin E is derived from vegetable oils, while synthetic versions are manufactured from petrochemicals.
NOW Foods uses natural d-alpha-tocopheryl acetate, which is a stable esterified form of natural vitamin E. This form is protected from oxidation and converts to active d-alpha-tocopherol in the digestive system. Choosing natural vitamin E can mean getting more biological activity from the same IU dosage.
Recommended Dosage and Form
The recommended dietary allowance (RDA) for vitamin E is 15 mg (about 22 IU from natural sources) for adults. Higher doses, such as 400 IU, are commonly used in supplements for targeted antioxidant support. The tolerable upper intake level for adults is 1,000 mg (about 1,500 IU) per day, so 400 IU is well within safe limits for most people.
Softgels are a convenient and effective delivery form for fat-soluble vitamins like vitamin E. The softgel contains the vitamin in an oil base, which enhances absorption because dietary fat helps the body utilise vitamin E. NOW Foods offers 400 IU softgels that are easy to swallow and can be taken with a meal containing fat for best results.
How to Choose the Best Vitamin E Supplement
When selecting a vitamin E supplement, consider the form (natural vs. synthetic), dosage, and additional quality indicators. Look for natural d-alpha-tocopherol or d-alpha-tocopheryl acetate on the label. Certifications like non-GMO, gluten-free, and vegan can also guide your choice.
NOW Foods Vitamin E softgels are non-GMO, soy-free, and vegan—suitable for a variety of dietary preferences. They are also manufactured under strict quality control practices, ensuring purity and potency. Always check the expiration date and store supplements in a cool, dry place to maintain freshness.
Potential Side Effects and Precautions
Vitamin E is generally safe when taken at recommended doses. High doses (above 1,000 IU daily) may increase the risk of bleeding, especially in individuals taking blood-thinning medications like warfarin or aspirin. If you are on anticoagulant therapy, consult your health care provider before using vitamin E supplements.
Other possible side effects at very high doses include nausea, diarrhea, stomach cramps, and fatigue. Stick to the serving size on the label (one softgel daily) unless otherwise directed by a health care professional. Keep out of reach of children.
