Vitamin Basics & Tips


Vitamin D plays a critical role in calcium absorption and bone health, particularly for individuals with limited sun exposure. The recommended daily allowance (RDA) for adults is 600-800 IU, but higher doses (like 30,000 IU weekly or daily, under medical supervision) may be prescribed to correct deficiencies. Sunlight triggers vitamin D synthesis in the skin, but factors like geography, skin tone, and sunscreen use reduce its efficacy. Regular blood tests (measuring 25-hydroxyvitamin D) are vital to monitor levels, with optimal ranges between 30-50 ng/mL. Deficiencies increase fracture risks, especially in older adults, as vitamin D supports bone density and muscle function.


Supplements are crucial for those avoiding sunlight or living in northern latitudes. Pairing vitamin D with magnesium and vitamin K2 enhances absorption and directs calcium to bones instead of arteries. Over-supplementation (above 4,000 IU/day without oversight) may cause toxicity, leading to hypercalcemia. Always consult a healthcare provider before starting high-dose regimens. Dietary sources like fatty fish, fortified milk, and egg yolks provide smaller amounts, making supplements practical for maintaining year-round adequacy.
