I will tell you the recipe for the synthesis of niacin from improvised means.
Nicotinic acid is a form of vitamin B3 (niacin). We obtain niacin from a wide variety of plant and animal products.
If you eat monotonously like some convict, you can get the pellagra disease. It is a niacin deficiency disease. Such people become covered with a rash, they develop diarrhea, they go crazy and die. This is why niacin is called a vitamin. We will not survive without vitamins.
Nicotine story
I have already tried a couple of times to rub a bike that our body synthesizes nicotine, which is vital for smokers. Now I seem to understand where the legs grow from this bike.
So, nicotine in our body, of course, is not synthesized. But nicotinic acid can be synthesized. Probably, because of this consonance, the confusion occurred.
Now someone will scream, "Aha! This vitamin is synthesized here. It means that it is not a vitamin. "In fact, some vitamin D is also synthesized in our country, but it is always lacking, and we need completely left ultraviolet light, which we do not have in our body.
Roughly the same story with nicotinic acid. It may simply not be enough, and for its synthesis inside our body, the amino acid tryptophan is needed.
Tryptophan is a naturally occurring amino acid that our body cannot make on its own. You have to eat it. There is a lot of tryptophan where there is a lot of protein: in meat, milk, cheese, legumes, nuts, seeds.
How to make yourself nicotinic acid for home use
You need to eat at least 100 grams of protein per day from the sources listed above. That is, on average, it will be more than one gram of protein per kilogram of weight. It's complicated.
If you count on the tables of food composition, you will understand that you need to eat in a variety of ways. This is because for one part of the niacin obtained, you need to eat at least 60 parts of tryptophan.
As a catalyst, I recommend adding vitamin B6, which is found in meats, vegetables, whole grains, and nuts. Without vitamin B6, tryptophan cannot convert to niacin.
It is also important to have inside the body various enzymes necessary for this, which in fact do not work correctly for every person.
If everything was done exactly according to the recipe, then you will no longer need the left vitamin B3, your body will be able to synthesize nicotinic acid on its own.
