When the person enters in his 70s, it is then that the body is only able to produce 40% of this vitamin and thus there arises a need to increase the intake of vitamin D. An adequate dosage of 200 IU of vitamin D is required by people who are in their 20s and for people who are older, 400 IU to 600 IU is needed to do the same amount of work.
As you age, Vitamin B intake should also be increased, as the lack of these vitamins, namely, folic acid, vitamin B6 and vitamin B12, in the body, puts you at a higher risk of heart disease and memory loss that characterize aging. As you age, increase your B6 dose from 2 mg to 5 mg; increase B12 over time from 2 mcg to 10 mcg. So, to overcome the problem of aging, ensure your sufficient intake of anti aging vitamins.
