Niacin, together with other B-vitamins, is a very important part of the energy metabolism pathways in the body. Lack of niacin leads to lower energy levels. I am sure you are tired and you can use a boost in energy. But don’t run to your medicine cabinet just yet. Most Americans consume enough niacin, measured as niacin equivalents (NE) to meet, and exceed their RDA. And more is not necessarily better; excess of niacin from supplements is known to cause adverse effects. How can you make sure you are getting enough NE from the diet without reaching for supplements? After all, why spend money if you don’t have to?
Let’s calculate the niacin intake for Alice and Harry, a young couple who are very active. They run in the morning and work out after work. They don’t take supplements and cook mostly natural foods, hardly ever buying foods that are enriched or in boxes. For your calculations, use their fairly typical diet from yesterday. We have supplied the amounts of niacin and tryptophan in their foods for you.
Dinner Preformed niacin 3.3mg Tryptophan 208mg
