Was deficient in vit d and B12 few years ago, would it be a good idea to check other vitamin blood tests like b3 or c or e to check cause of fatigue.?

In brief: Not really

B12 deficiency may be dietary or related to gastric disease.
Vitamin d is both absorbed and converted in the liver and skin to active forms. Vitamin c, e and others do not have the same absorption pathways nor the same actions. Vitamin k as an example is related to clotting, while e can help skin collagen deposition. They are all different and unique in function and action.

In brief: Maybe

Fatigue has many causes.
A visit with your health care provider might provide insight into the reason(s) you are fatigued. Vitamin deficiencies are not the most common causes of fatigue.
