The vitamin and mineral requirements of people over 70 years old are similar to those of younger adults with a few exceptions:
- There is an increased daily need for vitamin D (rising to 800 IU from 600 IU, or 20 mcg from 15 mcg) and for calcium (rising to 1,200 mg from 1,000 mg, although, for women, this increase begins at age 51.)
- The requirement for B6 is higher for women and men starting at age 51, rising from 1.3 mg to 1.5 mg for women and 1.7 mg for men.
- The only vitamin or mineral that older people need less of than younger adults is iron: Once over 50, the requirement among women falls from 18 mg per day to just 8 mg, which is the same requirement for men of all ages.
The requirement for vitamin B12 does not change, but, older are more likely to have trouble extracting B12 from foods (mainly meats) than younger people and may, therefore, require a supplement.
The complete vitamin and mineral requirements for people over 70 years old, as well as for adults of other ages, are shown in the table below. Upper limits for routine intake are also shown.

Other Nutritional Supplementation for People Over Age 70
If you are looking for a good, all-around multivitamin formulated for older adults, see our overall Top Pick for 50+, Top Pick for Women 50+ and our Top Pick for Men 50+, which can help you meet recommended intakes for nutrients such as vitamin D and B6, without iron.
Protein Powders, Shakes & Drinks
Extra protein (typically about 30 grams to 50 grams per day) can help older people prevent or reverse age-related loss of muscle (sarcopenia) and strength when used in conjunction with resistance-type exercise. If you already consume ample protein from your diet, extra protein won't help, even with exercise. Protein supplements may also help people with diabetes maintain blood sugar levels and even reverse diabetes if taken as part of low-calorie diet. Learn more about protein requirements for older adults and see our Top Picks among protein powders, drinks and shakes.
On average, people don't consume enough lutein and zeaxanthin in their diets and/or have low levels of lutein in their blood or low macular pigment density; for them, taking a lutein supplement may slow the progression of age-related macular degeneration (although it won't improve the condition) as well as reduce the risk of needing cataract surgery. It may also improve some aspects of brain function. See our Top Picks for lutein and zeaxanthin supplements, and those that most closely resemble vision formulas shown to be helpful in clinical trials, in our Vision Supplements Review.
