Niacin
For metabolic and detoxification support
A promising idea, with a smaller group behind it so far.
Niacin is worth exploring for energy, detox, and stress, but support is still early.
Who is behind it
Voices including a molecular biology PhD, a nutritional sciences PhD and a board-certified cardiologist.
How strong the research is
Mostly expert experience so far, with published research still catching up.
In their words
“Niacin or Nicotinic acid also known as vitaminB3 Are used to make serotonin which is the happy brain chemical and this is why some people feel crap when they give up smoking”

using regular plain old niacin increased NAD Plus in people with long COVID
Increasing niacin intake can alleviate symptoms related to niacin deficiency such as dermatitis, mental health issues, and digestive disorders.
This form of vitamin B3 supports oil regulation, calms visible redness and strengthens the skin barrier.
Niacinamide exerts protective responses by inhibiting lipolysis and use of fats favouring glucose use, and has the capacity to optimise cholesterol uptake and values.
Niacin as NAD⁺ is required for Complex I function in the electron transport chain.
With care
Some of the minds attach conditions. These are worth reading before you begin.
Niacin is more useful if you have elevated fibrinogen levels but not necessary for all.
Optimal thyroid function and niacinamide intake would have a general positive aerobic/oxidative effect on physiology.
