Best Supplements for Women After 40
After 40, a woman's nutritional needs shift significantly. Hormonal changes, decreased bone density, and metabolic shifts mean that the supplements that worked in your 30s may no longer be enough.
What Changes After 40
Estrogen decline affects calcium absorption, mood, and cardiovascular health. Muscle mass decreases without adequate protein and resistance training. Vitamin D, magnesium, and B12 absorption can all decline with age.
