Best Supplements for Women Over 40 for Energy: Turning 40 marks a significant milestone in a woman’s life. While it brings wisdom, experience, and self-confidence, many women notice a decline in their energy levels during this stage. Fatigue, sluggishness, brain fog, and difficulty bouncing back from daily stress are common complaints.
But why does this happen? Several factors contribute:
- Hormonal changes (perimenopause and menopause) affect metabolism, mood, and sleep.
- Nutrient absorption declines with age, making it harder to get enough vitamins and minerals from diet alone.
- Increased responsibilities (career, family, aging parents) often lead to stress and poor self-care.
- Reduced muscle mass and slower metabolism affect stamina.
The good news? With the right lifestyle choices and targeted supplements, women over 40 can restore vitality, reduce fatigue, and feel more energetic throughout the day.
In this comprehensive guide, we’ll explore the best supplements for women over 40 for energy, backed by science, along with natural lifestyle strategies to help you feel your best.
