Product analysis
E-400 D-Alpha with Mixed Tocopherols pairs vitamin E with selenium for nutritional support of normal antioxidant and immune functions when intake is low. Missing proportions within the vitamin E mixture limit close comparison with other products.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality70
Selenium-enriched yeast is a favorable selenium form. Vitamin E quality remains uncertain, and its different declarations do not establish one reliable combined total.
Ingredient Transparency80
The listed amounts and forms are disclosed. Missing proportions within the vitamin E mixture still prevent a complete composition comparison.
Value For Money52
Selenium offers moderate value at the whole-product cost. Value for the vitamin E contribution cannot be judged confidently.
Customer Satisfaction81
Customer feedback is very positive across several hundred ratings. The review base describes satisfaction without establishing immune benefits.
Product Focus84
The small ingredient list keeps the purpose centered on nutritional antioxidant and immune support. Extra benefit is uncertain when selenium and vitamin E needs are already met.
