For some individuals, vitamins and supplements can help fill nutrient gaps when diet alone isn’t enough. However, there’s limited evidence that supplements prevent chronic disease. In some cases, high doses may even cause harm or increase the risk of certain health conditions.
For example, research shows that people who smoke or have smoked may have a higher risk of lung cancer and cardiovascular disease when taking beta-carotene supplements. Many vitamins and minerals also have upper intake limits that are difficult to exceed through food but easier to surpass with supplements.
Eating a balanced variety of foods is the best way to meet your nutrient needs while also gaining benefits like fiber and antioxidants.
- Vitamin E: nuts, seeds, vegetable oils, spinach, fortified cereals
- Folate: orange juice, leafy greens, broccoli, peanuts, avocado, enriched grains
- Vitamin B6: potatoes, bananas, meats, whole grains, nuts, beans
- Vitamin B12: dairy, meat, fish, poultry, eggs
- Vitamin A (beta-carotene): orange/yellow fruits, root vegetables, leafy greens
Instead of relying on supplements, aim to stock your kitchen with nutrient-rich foods like fruits, vegetables, and whole grains. A well-balanced diet can support heart health and overall wellness. If you’re unsure whether your diet meets your needs, talk with a doctor or registered dietitian before starting supplements.
