Why It Matters for Longevity
Red Star T6635+ Vegetarian Support Formula nutritional yeast is listed as a vegan vitamin B12 source (1 mcg per 2 g serving, 17% DV). Baker's yeast is also listed as a folate source (23 mcg per ¼ tsp, 6% DV). Fortified nutritional yeast makes vitamin B12 accessible to vegans and vegetarians who cannot obtain it from animal products; B12 is essential for neurological function, DNA synthesis, and red blood cell formation.. Fortified nutritional yeast is one of the few plant-derived foods that can reliably raise serum vitamin B12 in vegetarians and vegans; studies confirm its B12 is bioavailable and prevents deficiency-related hyperhomocysteinaemia, a risk factor for cardiovascular disease and cognitive decline. (Watanabe et al., European Journal of Clinical Nutrition (2014) — PMID 24646707) Beta-glucans from Saccharomyces cerevisiae (the strain used in nutritional yeast) modulate immune function through dectin-1 receptor activation, reducing incidence of upper respiratory infections — an immune-support mechanism relevant to healthy aging. (Stokes et al., Journal of the Academy of Nutrition and Dietetics (2014) — PMID 24230159)

Synergies
- Pasta (complement): Nutritional yeast serves as a vegan Parmesan substitute, adding B12 and umami to pasta dishes in the Longevity Diet. - Legumes (complement): Legume-based meals gain a complete umami flavour boost from nutritional yeast while adding B12 and beta-glucans — all absent from plant proteins alone. - Omega-3-Fatty-Acids (synergy): Adequate B12 (from nutritional yeast) is required for normal homocysteine metabolism; combined with omega-3s from fish or flaxseed, this supports cardiovascular and cognitive longevity.
Flavor Profile
Taste: umami, cheesy, nutty, savory. Aroma: yeasty, nutty, mildly cheesy. Texture: fine flakes, powder. Category: condiment / flavoring / supplement.

Key Nutrients
| Nutrient | Per 100g | Notes |
|---|---|---|
| Vitamin B12 (cyanocobalamin, fortified) | ~50 mcg (fortified variety) | Bioavailability comparable to supplement cyanocobalamin; must be a B12-fortified strain (e.g., Red Star T6635+); unfortified strains contain no active B12. |
| Beta-glucans | ~1–5 g | Immune-modulating polysaccharides; bind dectin-1 receptors on macrophages and natural killer cells. |
| Protein (complete) | ~50 g (dry weight) | Contains all essential amino acids; relatively high PDCAAS for a plant source. |
| Folate | ~2340 mcg (unfortified yeast) | High folate content; important for single-carbon metabolism, DNA repair, and prevention of neural tube defects. |
