While women tend to need fewer calories than men, our requirements for certain vitamins and minerals are much higher. Hormonal changes associated with menstruation, child-bearing, and menopause mean that women have a higher risk of anemia, weakened bones, and osteoporosis, requiring a higher intake of nutrients such as iron, calcium, magnesium, vitamin D, and vitamin B9 (folate).

A number of implementation challenges exist for micronutrient supplementation. Access to care is often associated with socioeconomic status and may influence women's access to and use of supplementation programs. For instance, in one study, the highest wealth quintile of pregnant women had the highest use of iron and folic acid supplementation during antenatal care (33). However, even for women who have access to micronutrient supplements, the coverage and quality of micronutrient supplementation programs were limited (39). Incorrect doses, inadequate supplies, and incomplete adherence were major limitations (33), and poorly performing programs had limited impact on nutrition outcomes (59). Integration of supplementation programs with behavior change interventions improved knowledge, adherence, and coverage of supplementation interventions (32, 33, 60). The use of local micronutrient-rich foods can also help overcome limitations associated with supplement provision. In Nepal, improvements in the dark adaptation of night-blind pregnant women did not differ significantly between food and synthetic sources of vitamin A (61). When available, consumption of micronutrient-rich foods can be as effective as micronutrient supplements.

Among other things, you need calcium to build healthy bones and teeth, keep them strong as you age, regulate the heart’s rhythm, and ensure your nervous system functions properly. Calcium deficiency can lead to, or exacerbate, mood problems such as irritability, anxiety, depression, and sleep difficulties. If you don’t get enough calcium in your diet, your body will take calcium from your bones to ensure normal cell function, which can lead to weakened bones or osteoporosis. Women are at a greater risk than men of developing osteoporosis, so it’s important to get plenty of calcium, in combination with magnesium and vitamin D, to support your bone health.
In the past, women have often tried to make up deficits in their diet though the use of vitamins and supplements. However, while supplements can be a useful safeguard against occasional nutrient shortfalls, they can’t compensate for an unbalanced or unhealthy diet. To ensure you get all the nutrients you need from the food you eat, try to aim for a diet rich in fruit, vegetables, quality protein, healthy fats, and low in processed, fried, and sugary foods.
