In this video, we’re going to talk about niacin deficiency symptoms. If you have a niacin deficiency, you might experience the “4 D’s”: dermatitis, diarrhea, dementia, and even death.

Subclinical symptoms of a niacin deficiency include the following:
• Loss of taste
• Metallic/rancid taste in the mouth
• Loss of smell/change in smell
• Face moves when you look in the mirror
• Words move when you read
• Unstable or moving ground when walking
• Fatigue
• Inability to relax

You need large amounts of niacin to address a deficiency. You can take either niacin or niacinamide.

Niacin is a precursor to NAD, which helps extract electrons from foods. This allows you to get more energy from the food that you eat.

Vitamin B3 helps support something known as sirtuins, which support longevity and DNA repair. L-tryptophan can convert to niacin, serotonin, and melatonin!

Niacin is very beneficial for skin health and conditions like acne and psoriasis. A niacin deficiency can cause very dry, scaly skin.

The form of niacin known as niacinamide can help with inflammatory conditions like arthritis. Niacin also supports healthy levels of LDL and HDL cholesterol. It was very popular before the development of statins.

Animal protein and organ meats are the best sources of niacin. You can also get niacin from spirulina and nutritional yeast, but look for nutritional yeast that does not have added synthetic vitamins.

There is a tremendous amount of research on niacin and cholesterol, the heart, and mood disorders like schizophrenia, depression, and bipolar disorder.

A diet high in ultra-processed foods can lead to a niacin deficiency. Pregnancy, alcoholism, Covid-19, and certain medications can also contribute to a niacin deficiency.
