Overview

Vision Advantage provides key vision-supporting nutrients like Lutein, Zeaxanthin, and Astaxanthin at clinically relevant dosages. Vitamins C, E, and A, along with Zinc, also contribute to overall eye health and antioxidant protection. However, the efficacy of the extensive blend of traditional herbal extracts is largely unquantifiable due to the lack of specific individual ingredient amounts within proprietary complexes. This limits a comprehensive assessment of their contribution to the product's overall effectiveness beyond the well-dosed carotenoids and vitamins.

The Good

Provides clinically studied doses of Lutein (10mg) and Zeaxanthin (2mg), which are crucial for macular health and filtering harmful blue light.

Includes Astaxanthin (6mg), a potent antioxidant supporting eye health and reducing oxidative stress.

Contains essential vitamins (C, E) and minerals (Zinc) that contribute to overall eye function and provide antioxidant protection.

The Bad

Vitamin E at 673% Daily Value (101mg) for prolonged periods may be associated with increased all-cause mortality, especially doses above 400IU (268mg).

Vitamin A at 333% Daily Value (3000mcg RAE) is at the adult upper tolerable intake limit, risking side effects like headache, blurred vision, and potentially increased risk of bone problems or certain cancers with chronic high intake.

Many herbal ingredients (Hachimijiogan Herbal Complex, Astragalus Extract, Asiatic Dogwood Extract, Chinese Yam Extract, Mountain Peony Extract, Poria Extract, Rehmannia Extract, Asian Water Plantain Extract, Schisandra Extract, Triphala Complex, Amla Extract, Belleric Myrobalan Extract, Chebulic Myrobalan Extract) are part of proprietary blends or their individual amounts are not disclosed, making it difficult to assess their efficacy at the given doses.
