How Much Vitamin D You Need

• Daily Amounts – Infants need 10 mcg (400 IU), ages 1 to 70 need 15 mcg (600 IU), and adults 71 and older need 20 mcg (800 IU). The same 15 mcg applies during pregnancy and breastfeeding.^[1]
• Food – Very few foods have vitamin D naturally. Fortified milk and plant milks, fortified cereals, fatty fish and fish liver oils are the main sources.^[1]
• Sun – Your skin makes vitamin D in sunlight, but clouds, smog, age and dark skin reduce it, and sunscreen limits production.^[1]
• Blood Test – A 25-hydroxyvitamin D blood test is the way to know if you are getting enough. Levels of 50 nmol/L (20 ng/mL) or above are adequate for most people.^[1]

---

Who Is More Likely to Run Low

• Breastfed Infants – Breast milk alone does not provide enough, so breastfed infants need a 10 mcg (400 IU) supplement each day.^[1]
• Older Adults and Darker Skin – Skin makes less vitamin D with age and with more melanin.^[1]
• Little Sun Exposure – People who stay indoors, cover their skin, or live where winter sun is weak make less.^[1]
• Fat Absorption Conditions – Crohn’s disease, celiac disease, ulcerative colitis, obesity and gastric bypass can all affect vitamin D, so ask your doctor about testing.^[1]

What to Check on a Vitamin D Label

• D2 or D3 – Both forms raise vitamin D in your blood, but D3 might raise it higher and for longer. Ora Organic and Garden of Life make vegan D3 from lichen.^[1]
• Amount – The label shows mcg and IU per serving. Add it to what you get from food and a multivitamin so you stay below the upper limit.^[1]
• Take It With Food – Vitamin D is fat soluble, so it is absorbed best with a meal or snack that includes some fat.^[1]
• Organic Seal – Look for the USDA Organic seal for certified organic ingredients, and note when the label only says organic ingredients.^[3]
• Other Ingredients – Gummies and chewables add sugar and flavor. For more nutrients in one product, see our organic multivitamin picks.

What the Research Says

The NIH Office of Dietary Supplements says vitamin D helps your body absorb calcium and supports bones, muscles, nerves and the immune system, and that vitamin D and calcium supplements slightly increase bone strength in older adults.^[1] Clinical trials do not show that vitamin D supplements prevent heart disease, depression, type 2 diabetes or most cancers, or help with weight loss.^[1] Fortified foods supply most of the vitamin D in U.S. diets, and supplements fill the gap when food and sun are not enough.^[1]
