As we age, especially after 50, maintaining healthy blood circulation becomes vital. Poor circulation can quietly lead to serious health issues, particularly in the legs and feet. One powerful aid in this area is niacin, or vitamin B3, a micronutrient that plays a major role in improving circulation. It helps widen blood vessels, reduce inflammation, and improve how our cells use fats and sugars. Notably, niacin can lower triglycerides and increase good cholesterol (HDL) by up to 35%, helping prevent plaque buildup that restricts blood flow. These benefits become even more crucial with age, as the cardiovascular system naturally begins to slow down and stiffen. A study even found that a related compound, nicotinamide riboside, improved walking ability in people with poor leg circulation. Participants with peripheral artery disease could walk farther after taking this vitamin B3 form, thanks to better energy and muscle repair. This suggests niacin could be a game-changer for mobility and overall vascular health in older adults. With circulation issues affecting around 40% of Brazilians over 50, the right nutritional support could prevent many of these problems.
Getting Enough Niacin
Niacin is found in foods like chicken, turkey, tuna, salmon, peanuts, sunflower seeds, and whole grains. It can also be produced by the body from tryptophan, a nutrient in protein-rich foods. Supplements are available, but high doses should only be taken under medical supervision due to possible side effects like skin flushing or liver damage. For most adults, the recommended daily intake is 14–16 mg. For heart-related treatments, higher doses are used cautiously under a doctor’s care.
