« Early knowledge about proper nutrition can completely change our health trajectory in our 50s and 60s. »
Why I Decided to Learn About Nutrition for Women Over 40
The story began when my friend Sarah (47) told me about her experience with vitamin D deficiency and how it affected her energy and mood. She said, « Maya, you’re only 42, but your body is already preparing for changes. The smart woman starts preparing now. »
That day completely changed my perspective on health. I decided to invest in understanding nutrition for women over 40 before I started experiencing symptoms or problems.

What worked for me: Adding vitamin K2 and magnesium to my daily routine through whole foods and targeted supplements made a real difference.
