Best supplements like Sightcare for improving eyesight naturally.

Vitamin A (Beta-Carotene) Essential for rhodopsin production, a pigment critical for low-light vision, vitamin A deficiency can lead to night blindness. Beta-carotene, its plant-based precursor, is safer for long-term use. Sources: Carrots, sweet potatoes, liver. Dosage: 700–900 mcg RAE (2,300–3,000 IU beta-carotene). Vitamin C This water-soluble antioxidant regenerates vitamin E and supports collagen synthesis in the cornea. The AREDS2 study found it reduces AMD progression by 25% when combined with other nutrients. Sources: Citrus fruits, bell peppers. Dosage: 500–1,000 mg daily. Vitamin E Protects cell membranes from oxidative damage. Trials indicate that 400 IU/day of vitamin E, paired with other antioxidants, lowers cataract risk. Sources: Nuts, seeds, spinach. Dosage: 15 mg (22.4 IU) daily. 3. Essential Minerals: Building Blocks for Eye Health Zinc Zinc transports vitamin A to the retina and supports melanin production, a protective pigment. The AREDS2 formula includes 80 mg zinc oxide, shown to slow AMD progression. Sources: Oysters, beef, legumes. Dosage: 25–40 mg daily (with copper to prevent deficiency). Copper and Selenium Copper aids iron metabolism and works synergistically with zinc. Selenium boosts glutathione activity, defending against oxidative stress. Sources: Shellfish, Brazil nuts. Dosage: 2 mg copper, 55 mcg selenium daily. 4. Omega-3 Fatty Acids: Moisture and Clarity DHA, a primary structural fat in the retina, supports photoreceptor function. EPA reduces inflammation linked to dry eye syndrome. Studies show 1,000–2,000 mg/day of combined EPA/DHA improves tear production and visual development in infants. Sources: Fatty fish, algae oil. Dosage: 500–1,000 mg DHA + EPA daily. 5. Herbal Supplements: Traditional Remedies Revisited Bilberry Extract Rich in anthocyanins, bilberry may enhance night vision and retinal blood flow. WWII pilots reportedly used it for improved night missions, though modern evidence remains mixed. Dosage: 160–480 mg standardized extract daily. Ginkgo Biloba By enhancing circulation, ginkgo may benefit glaucoma patients. A 2012 study noted improved visual field in those taking 120 mg/day. 6. AREDS2 Formula: A Science-Backed Blend Developed by the National Eye Institute, this combination includes vitamins C (500 mg), E (400 IU), lutein (10 mg), zeaxanthin (2 mg), zinc (25 mg), and copper (2 mg). It’s proven to reduce AMD progression by 18–25% in at-risk individuals. 7. Emerging Antioxidants: Alpha-Lipoic Acid (ALA) and NAC ALA regenerates other antioxidants and may mitigate diabetic retinopathy. NAC boosts glutathione, protecting against glaucoma. Dosage: 300–600 mg ALA; 600–1,800 mg NAC daily.
