Without enough vitamin D, parathyroid hormone mobilizes bone calcium and increases reabsorption of calcium from the kidneys.

Vitamin D helps pregnant woman by preventing high blood pressure, pre-eclampsia and gestational diabetes. Its need increases in pregnancy and breastfeeding. Researchers found that its deficiency affects 18-84% of pregnant women.

It also improves mood by regulating the release of glutamine, noradrenaline, serotonin and dopamine. It helps in reducing inflammation in your cells.

B Vitamins

As you are actively working at this age, take B vitamins for a better mood, energy, and mental focus as they support cognitive and nerve health and a healthy metabolism. They are essential for fulfilling the everyday energy requirement as they produce energy from food. Athletic females need more of them.

These are the child-bearing years, if you are trying to conceive, you must take folic acid (B9) that is particularly important for brain development, DNA replication for new cell formation, and preventing neural tube defects, malnourishment, premature birth and restrictions in fetal development. It plays a key role in cellular reproduction and cell growth.

Even if you are not pregnant or trying to conceive, you still can have it for your healthy cell growth. It supports your hair, nail and skin growth and health and prevents depression, breast cancer and heart diseases.

Women in this age are greatly concerned about the beauty of their hair so keep in mind that biotin promotes hair health and must be there in your diet.

Less reproductive hormones estrogen and progesterone in this age make women susceptible to night sweats, hot flashes, mood swings, brain fog, depression, urinary incontinence, decreased sex drive, insomnia, osteoporosis, heart disease, and thinning skin. Following vitamins should be given importance for healthy ageing.
Vitamin D

Vitamin D is still essential rather you can say extremely essential as bone health starts deteriorating at this age and women are at greater risk for osteoporosis. So now, vitamin D is preserving bones instead of building them.

Incorporating vitamin D with K2 works better for bone calcification. Vitamin D also keeps your muscle, nervous and immune system working right to fight off germs that make you sick.

B Vitamins: B6, B9 and B12

Vitamin B6 will fight germs, make energy from food and keep your brain working well. It helps in making serotonin that transmits brain signals and tackles mood swings and depression in menopause. You should eat foods that have this nutrient in them rather than supplement as if you get too much of it at once, it can be toxic. Its RDA increase from 1.3 to 1.5mg after 50 years of age.

B9 can help your body in making estrogen during menopause.

As B12 absorption from food decreases with advancing age and according to FNB, about 10-30% of older ones don’t get enough of it, it is recommended that you take it as a supplement to keep yourself energetic and blood and nerve cells healthy. Along with that, take nutrient-dense foods as only then B-Vitamins can produce energy from them.

B 12 is the most important energy producer from food. It aids in metabolism, bone health, and neurological function. Its deficiency over time can make you fatigued, weakened, constipated, and anaemic. It can even cause peripheral neuropathy, loss of appetite, numbness and tingling in the hands and feet, depression, confusion, balance problems and dementia. So, for better health, be sure to have its recommended amount that is 2.4 micrograms daily for women 14 and older.

Research has found that B vitamin intake may decrease the risk of many conditions that affect older women frequently.

Vitamin A

It may aid in maintaining bone health after menopause.

Vitamin E

This antioxidant prevents free radical damage to cells that reduce disease risk. It combats depression, heart disease, weight gain that are all caused by cell damage due to stress. Include at least 15mg daily.


From now onwards, you mostly have to rely on supplements to stay on top of your game rather than getting the vitamins from food only as guts become less efficient with age limiting the ability to get sufficient nutrients from food.

Vitamin B12

To prevent dementia, older women need a daily recommended dose of vitamin B12. The research found that up to 62% of over 65 year age adults don’t have optimal blood levels of it. Supplementation of 100 older adults with 500mcg for 8 weeks normalizes their levels in 90% of the participants. Some even need more than that dose.

Vitamin D

It not only helps in calcium absorption from food but can also treat chronic pain, protect against cardiovascular disease, and ward off cancer, asthma, allergy and inflammation. Low levels increase your risk of osteoporosis, diabetes, hypoglycaemia, hypertension, depression and rheumatoid arthritis. More than one in four Americans of 50 to 71 years are not taking enough vitamin D. As your body can’t synthesize it now from sunlight, supplement vitamin D3 in a recommended dose of 600 IU daily.  


Important vitamins to take at this age are:

Vitamin D

It is essential during your 70’s and its need increase to 800 IU daily according to the National Institute of Health now. It is required for bone health and maintains muscle mass which naturally begins to deteriorate at this stage. It also protects against illness and infection. As the body’s ability to synthesize vitamin D from sunlight decreases with age, consider vitamin D3 supplement.

Vitamin B12

As your age advance, it is harder for your body to make, use or absorb vitamin B12 from food as stomach acid declines with age. So, it is advised that you supplement with B12 as even a mild vitamin B12 deficiency may put the older woman at dementia risk because of its role in optimal brain function.

80’s and up

During your octogenarian years and next, supplemental B12 may be important and also keep up with your vitamin D. Keep your doctor informed about any changes in diet or medication to get the guidance accordingly.
