Vitamin Basics & Tips

Vitamin A plays a crucial role in maintaining vision health, particularly night vision, by supporting retinal function. Its antioxidant properties help protect eyes from age-related decline and reduce risks of conditions like macular degeneration.

Beyond ocular benefits, vitamin A strengthens immune responses by maintaining mucosal barriers in respiratory and digestive systems. This essential nutrient also promotes skin health by regulating cell production and supporting collagen formation, making it valuable for addressing acne or psoriasis.

Dietary sources include sweet potatoes, spinach, and liver, though supplements help bridge nutritional gaps. However, excessive intake (above 3,000 mcg RAE daily for adults) can cause toxicity symptoms like dizziness and joint pain. Always consult healthcare providers before combining supplements with vitamin A-rich diets or medications.
