Raw nutritional yeast

Raw nutritional yeast (+unfortified) has lots of B vitamins. Supposedly, it can be raw if it is deactivated (killed) by drying instead of heat and it is technically raw. It does not have B12 but the other Bs are there.

The 5 most powerful nutrients for the immune system are:

1 Vitamin C
2 Vitamin D
3 Zinc (pumpkin seeds)
4 Selenium (Brazil nuts)
5 Beta glucans

Nutritional yeast has lots of beta glucans (in the cell membrane)


Beta-glucans are polysaccharide chains consisting of several D-glucose units linked together by beta 1-3 and beta 1-4 bonds, with or without branching.

Beta-glucans are not digested or absorbed by our digestive system because humans do not have the enzymes to break them down. They, therefore, arrive intact in the small intestine, where some of them act as dietary fibres and others as biologically active substances on the cells of the immune system.

Yeast and mushroom beta-glucans have immunomodulatory properties. Their mode of action is complex as they interact with various receptors on different cell types and can act on both innate and adaptive immune responses. (De Marco Castro, 2020)

It has been proposed that beta-glucans interact directly at the Peyer’s patches located in the membrane of the small intestine. Peyer’s patches are areas in the intestines containing a cluster of many immune cells and are essential for initiating and regulating the immune response.

Beta-glucans are ingested by macrophages that participate in activating other cells involved in the immune system, enhancing antimicrobial activity against viruses, bacteria, yeast, and fungi.

Beta-glucans and the immune system to prevent flu and colds

Several studies have been published on the role of beta-glucans from fungi and yeast in treating and preventing recurrent respiratory infections such as the common cold or flu in children, adults, and athletes. Respiratory infections are common at all ages, and some people may have up to 6 episodes per year.

Clinical studies using beta-glucans obtained from the yeast Saccharomyces cerevisiae have shown that they help reduce the recurrence of respiratory tract infections, the severity of their symptoms, and decrease episodes of allergy and allergic rhinitis. (Jesenak, 2017)

To contribute to the immune system’s proper functioning, the daily dose of yeast beta-glucans used in the various clinical studies is between 100 and 900 mg.

Nutritional yeast skives me. It's processed food. I don't use anything fermented like Miso, Soy Sauce, Amino Acids, Kombucha, borsch, all that stuff. Rejuvalac would be the worst.

But it's good to know those best sources of Nutritional Yeast - Foods Alive, Sari, etc.

This article covers the problems that some may have if they don't buy one of the good nutritional yeast -

To get the B12 in raw food you need dried nori. The B vitamins keep the brain calm as the brain uses tons of energy (the original old style CPU).


A survey of naturally occurring and high Vitamin B12-containing plant-derived food sources showed that nori, which is formed into a sheet and dried, is the most suitable Vitamin B12 source for vegetarians presently available. Consumption of approximately 4 g of dried purple laver (Vitamin B12 content: 77.6 microg /100 g dry weight) supplies the RDA of 2.4 microg/day.

That's very helpful! Thanks, Panchito!

Regarding Sea Vegetables - we used to call it Seaweed - I read that with Kelp, you have to be careful not to eat too much because there is a lot of Iodine in it.
