Frequently Asked Questions
How much calcium do I need daily?
Most adults need 1,000 mg of calcium per day. Women over 50 and pregnant or lactating women often need 1,200–1,300 mg.
Can I get enough vitamin D from sunlight alone?
Sunlight helps, but factors like latitude, skin tone, season, and sunscreen use affect synthesis. Many people still need dietary sources or supplements.
What are good food sources of calcium?
Dairy products, fortified plant milks, leafy greens, tofu, and almonds are excellent sources of calcium.

Yes. Excessive calcium can cause kidney stones, and too much vitamin D can lead to toxicity. Stay within recommended upper limits unless directed otherwise.
