Thiamine - essential for energy metabolism
We rank Vitamin B1 by price per 1.1mg - 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 B1 is a nutrient also known as thiamine. It is an essential vitamin, meaning the body cannot make it on its own and it must be obtained through food or supplements.
Why it's used
It is primarily used to support energy metabolism, which is the process the body uses to turn the food you eat into fuel for your cells.
How it's made
To create the supplement, thiamine is produced through a chemical synthesis process in a laboratory. This resulting powder is then measured and packed into capsules or pressed into tablets for sale.
What it typically costs
This ingredient is generally mid-range in price. This is because the chemical synthesis required to produce it is relatively straightforward, but it still requires specific industrial quality controls to ensure purity.
