First described in the 18th century, Casal's necklace, or Casal's collar, is a distinctive red and hyperpigmented rash around the neck, serving as a tell-tale sign of pellagra, a severe nutritional disorder. Historically, it was named after the Spanish physician Don Gaspar Casal, who first identified the syndrome among the poor population in Spain in 1735.

NAD+ levels decline with age, dropping significantly from young adulthood. This crucial coenzyme, essential for cellular energy production, DNA repair, and activating key longevity-regulating proteins called sirtuins, can be supported through diet and lifestyle choices.

According to the World Health Organization, pellagra remains endemic in certain regions where limited diets are common. This condition, the disease due to vitamin B3 deficiency, can cause severe and widespread symptoms if left untreated.

Recent research indicates that cellular NAD+ levels can decline by as much as 50% with age, impacting cellular energy and repair functions. Understanding what vitamins NAD contains is therefore crucial for maintaining metabolic health, as the body relies on these specific precursors to synthesize this vital coenzyme for proper cellular function.

Nutritional yeast is often fortified with niacin, a B vitamin. According to the National Institutes of Health, the tolerable upper intake level (UL) for niacin in adults is 35 milligrams per day. Some fortified nutritional yeast products can contain this amount or more in a single serving. Therefore, it is a significant source of niacin.

Despite being part of the B-vitamin complex, vitamin B5 and niacinamide are not the same ingredient. While both play a vital role in cellular metabolism and skin health, their specific functions, benefits, and chemical structures are distinct, making them suitable for different skin concerns.

While both are essential B-complex nutrients, a common misconception is that pantothenic acid is a vitamin B3. In fact, pantothenic acid is correctly identified as vitamin B5, and it has a different set of functions and sources than vitamin B3, also known as niacin. This distinction is crucial for understanding how each vitamin contributes to your overall health.

Niacin, also known as vitamin B3, is involved in over 400 biochemical reactions in the body, primarily through its function as a precursor to the coenzymes NAD and NADP. This essential vitamin's main purpose is to help convert food into usable energy, but its roles extend far beyond basic metabolism.

Historically, certain populations that relied heavily on untreated corn as a dietary staple developed pellagra, a disease caused by niacin deficiency. This fact, observed over generations, raises the important question: Does corn have niacin, and if so, why does a diet of untreated corn sometimes lead to nutritional problems? The answer lies in the unique way the vitamin is bound within the corn kernels, and the traditional processing methods used to unlock it.

While many animal products contain high levels of vitamin B3, one cup of cooked portobello mushrooms provides a significant amount, making it a top contender for what vegetable is highest in niacin. This essential vitamin is crucial for converting food into energy and supporting the nervous system.
