Vitamin Basics & Tips
Vitamin A plays a crucial role in maintaining ocular health, particularly for aging vision. Retinol, its active form, supports retinal function and helps prevent night blindness – a common concern addressed in the review. As we age, the body's ability to convert beta-carotene to usable Vitamin A decreases, making direct supplementation increasingly valuable.
Dietary sources like sweet potatoes and spinach provide beta-carotene, while animal products contain preformed Vitamin A. However, absorption rates vary significantly, with studies showing supplements like Carlson's can provide 75-90% bioavailability compared to 20-30% from plant sources. The American Optometric Association recommends 700-900 mcg RAE daily for adults, emphasizing the importance of proper dosing to avoid toxicity.
For aging populations, Vitamin A works synergistically with nutrients like lutein and zeaxanthin to combat macular degeneration. Recent research in the Journal of Ophthalmology (2023) confirms that consistent Vitamin A intake correlates with reduced progression of age-related visual acuity loss when combined with regular eye exams.
