Special Nutrient Needs of Older Adults
Vitamin B12 B12 is important for creating red blood cells and DNA, and for maintaining healthy nerve function. “Getting enough B12 is a challenge for older people because they can’t absorb it from food as well as younger people,” says Tucker. “Even if your diet contains enough, you may be falling short.”
Vitamin D helps the body absorb calcium and is essential to keeping bones strong and warding off osteoporosis as we age. Despite vitamin D’s importance, it’s one of the most common vitamin deficiencies – as many as three-quarters of America’s seniors may not be getting enough of it.
According to a 2013 poll, 68 percent of Americans aged 65 and older take vitamin supplements. While vitamins can be beneficial, there’s scant evidence they can actually prevent chronic disease — to the point that the U.S. Preventive Services Task Force (USPSTF) doesn’t recommend the regular use of any multivitamins.
While megadoses of up to 2,000 mcg are considered safe in treating B12 deficiency, it’s always best to avoid excessive amounts of any vitamin, especially when it’s not needed.
No interactions were found between Vitamin B12 and Vitamin D3. This does not necessarily mean no interactions exist. Always consult your healthcare provider.
In particular, he says, older adults may lack calcium, vitamin D, vitamin B12, potassium, and fiber. Changing the diet can be difficult for older people, he says.

Most multivitamins should be taken once or twice per day. Make sure to read the label and follow the recommended dosage instructions. Multivitamins are available in pharmacies, large discount stores, and supermarkets, as well as online. Multivitamins are supplements that contain different vitamins and minerals.
Recommended Vitamin B12 Dosage for Seniors A recent study found that for seniors, a daily dose of 500 micrograms was efficient in reversing the signs of B12 deficiency. In general, experts recommend 2.5 micrograms of vitamin B12 per day for people over the age of 14.
The recommended dose for treating vitamin B12 deficiency is 1000 mcg daily. The recommended dose for preventing vitamin B12 deficiency is 1500 mg or 2500 mcg (sublingual tablets) daily. The dose for treating hyperhomocysteinemia is 400 mg daily in combination with folic acid.
In one 8-week study in 100 older adults, supplementing with 500 mcg of vitamin B12 were found to normalize B12 levels in 90% of participants. Higher doses of up to 1,000 mcg (1 mg) may be necessary for some ( 10 ).
