Energy-oriented formulas rarely include a full vitamin panel, but a subset recurs: B-group vitamins, vitamin C, zinc, and sometimes magnesium. B vitamins are tied to normal energy metabolism, which is why they appear in almost every blend with the word energy on the front.
Vitamin C and zinc are added both as nutrients and because they fit the general wellness framing of vitamins and minerals for men. Magnesium shows up less often and usually in formulas that lean toward training support rather than general daily use.
If a formula lists only botanicals and no nutrients at all, it has moved into a different category and should be judged as one. That is not a fault, but it changes what you should expect from the product and how you would compare it with a stacked blend.
