9 Supplements Doctors Recommend Most to Support Healthy Aging

4. Magnesium

Magnesium plays a critical role in cellular function, influencing inflammation levels, cardiovascular health, and neurological processes. Deficiency in magnesium has been associated with increased chronic inflammation, a recognized contributor to diseases such as heart disease, cancer, and Alzheimer’s disease.

Additionally, magnesium supports restful sleep, which is linked to longevity and overall well-being. Blood tests can confirm magnesium deficiency, and a healthcare provider can recommend the most suitable supplement form.

5. CoQ10

Coenzyme Q10 (CoQ10) is a naturally occurring antioxidant essential for mitochondrial energy production. As levels decline with age, supplementation may help reduce oxidative stress and inflammation, supporting heart function and cellular health.

However, CoQ10 can affect blood pressure and blood sugar levels. People taking medications to control these parameters should consult their doctor before starting CoQ10 supplements.

6. Fiber

Dietary fiber supports gut barrier integrity and reduces chronic inflammation, both pivotal for healthy aging. Adequate fiber intake has been linked to lower all-cause mortality and reduced risks of cardiovascular disease and cancer.

Since most Americans do not meet daily fiber recommendations, supplements containing psyllium or wheat dextrin can be effective for improving gut and immune health, particularly for older adults.
