If your diet consists primarily of plant-based foods like fruits, veggies, beans, and meat substitutes- as many vegetarian or vegan diets do, then you will be at risk for B12 deficiency
Hormonal deficiencies and mineral imbalances are common as well
Because nicotinamide would otherwise re-enter the NAD+ salvage pathway through NAMPT and NMN, NNMT activity sits at a junction between cellular methylation capacity and NAD+ regeneration, which is why the enzyme became a target after Kraus and colleagues (Nature, 2014) reported the consequences of antisense Nnmt knockdown in white adipose tissue and liver
By treating metabolically active adipocytes and hepatocytes with 5-amino-1-methylquinolinium, researchers can precisely inhibit intracellular NNMT activity, monitor changes in the nicotinamide pathway and NAD+ levels, and analyze effects on energy metabolism
Patients with pernicious anemia or others who cannot absorb B from food typically need lifelong B therapy, often on a monthly injection schedule
Supporting Your Immune System Regular exercise can temporarily suppress immune function, making immune system support crucial for maintaining consistent training
