Vitamin Basics & Tips


Vitamin D plays crucial roles in bone health, immune function, and mood regulation. While sunlight exposure remains the primary natural source, many people require supplements due to limited sun exposure or dietary restrictions. The recommended daily allowance varies between 400-800 IU for most adults, though some individuals may need higher doses under medical supervision.


Supplements come in D2 (ergocalciferol) and D3 (cholecalciferol) forms, with D3 being more effective at raising blood levels. Absorption can be enhanced when taken with fatty foods. Regular blood tests help monitor levels, as excessive intake (above 4,000 IU/day long-term) may cause toxicity symptoms like nausea or kidney issues.


Natural food sources include fatty fish, fortified dairy products, and egg yolks. Those with darker skin, older adults, and people with obesity often have increased vitamin D needs. Combined with calcium, it helps prevent osteoporosis, while emerging research suggests potential benefits for heart health and depression management.
