Niacin - supports energy metabolism and DNA repair
We rank Vitamin B3 by price per 16mg - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
What it is
Vitamin B3 is a water soluble vitamin, meaning it dissolves in water and is not stored in large amounts by the body. It is most commonly known as Niacin, a nutrient that helps the body turn food into fuel.
Why it's used
It is primarily used to support energy metabolism, which is the process your body uses to convert nutrients from food into usable energy. It also plays a key role in DNA repair, helping to fix damaged genetic material within your cells.
How it's made
Commercial Vitamin B3 is typically produced through a chemical synthesis process. Raw materials are reacted in a controlled industrial environment to create the pure powder, which is then measured and packed into capsules or pressed into tablets.
What it typically costs
This ingredient is generally mid-range in price. This is because the chemical synthesis required to produce it is straightforward and efficient, but it requires specific quality controls to ensure purity.
