I was prescribed supplements by my rhumatologist as they found that I had a low Vitamin D level (found on blood test) though for me I guess it was related to the impact on bones and related pain from that.
I didn't notice a huge difference though I think Vit D is one of the fat soluble vitamins I don't think I can process properly due to bile acid malabsorption so maybe as I wasn't on meds for that then yet.
I feel much better when the malabsorption is under control, loads more energy etc... and I do hurt a bit less (considering I have inflammatory arthritis anyway), less bone pain it seems anyway. I'm not sure if it's related but my pelvis and leg bones especially seem to hurt when my malabsorption is not being controlled.
Could your iron level be a bit low or could you be anaemic if they are too low? I've had low iron levels and find iron supplements help perk my energy levels up then.
I think it's easier to feel tireder when it's dark so much anyway though.
