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.

Evidence-Informed Supplement Priorities

• Magnesium glycinate — supports sleep, muscle function, and mood
• Vitamin D3 + K2 — bone health and immune wellness support
• Collagen peptides — supports skin, joint comfort, and connective tissue
• Probiotics — supports digestive wellness and immune balance
