Niacin comes in a couple different forms‚ one of which is niacinamide. This nutrient helps your body break down carbohydrates‚ proteins‚ and fats so it can use them to create energy and keep you healthy. It also helps certain parts of your body stay in great shape‚ including your skin‚ eyes‚ and liver. Eating foods like beets‚ beef liver‚ tuna‚ peanuts‚ and sunflower seeds can help you get enough niacinamide. You might have lower levels of this nutrient if you don’t eat these foods or if you struggle with alcoholism. Potential signs of a deficiency include indigestion‚ vomiting‚ canker sores‚ or a skin condition called pellagra. In order to boost your niacinamide levels‚ you may need to take a supplement.
