As you enter your 40s and beyond, your body starts to change in subtle but significant ways—especially your heart. While lifestyle remains the foundation of heart health, many adults in the U.S. over 40 turn to supplements to fill nutritional gaps, support energy, and reduce cardiovascular risks.
The right supplements can complement a healthy diet and exercise routine—but they’re not all created equal. Here’s a science-backed guide to heart-supportive supplements worth considering after 40.
⚠️ First, A Quick Note
Supplements should never replace medications prescribed by your doctor. They also work best when combined with healthy habits—clean eating, movement, good sleep, and stress reduction.
Always speak with a licensed U.S. healthcare provider before starting any new supplement—especially if you’re on blood thinners, statins, or have a medical condition.
