The simple and most accurate answer is: Yes, it absolutely can, but only if your fatigue is caused by a B12 deficiency

Its mechanism is purely metabolic: it directly targets lipid metabolism via inhibition of NNMT and restoration of cellular NAD+

The effect is not forceful or synthetic

You might be a good candidate if you have confirmed low B12 levels (from lab work), follow a strict vegan/vegetarian diet, have digestive issues reducing B12 absorption (e.g., after gastric surgery, or with conditions like Crohns), or experience chronic fatigue and other symptoms linked to B12 deficiency
