Each supplement has complements, so what happens is if you take one, you need to take the other. This, from experience, so, for example, I have noted the depletion of magnesium, if I happily take lots of vitamin D that cures all my ills - a little tick develops in a tiny muscle, and I have trouble sleeping, all of a sudden - so time to concentrate on magnesium also. One needs both, therefore:

If taking vitamin D, also take magnesium.

If taking vitamin C - although this vitamin can function by itself quite well - eventually, also take Iron (+ Eat enough meat), vitamin K and Quercetin. Beware that there is also an Iron/Calcium imbalance that especially athletes and pregnant women really have to watch. For example, too many dairy products (very nutritious, obviously) and the iron-levels can dip - even a daily smoothie incorporating skim-milk will do this. Vitamin C can help the iron uptake (+ eating more meat, less dairy) in those cases.

If taking Ivermectin take Zinc, because ivermectin and zinc work together.

I would also make a shout out to vitamin B, to keep the good mood up, give some energy, and serve as an emergency oops-we-feel-unwell drink (i.e., the effervescent tablets) in conjunction with a dissolvable aspirin. This last one is just lovely. We like to add ginseng, milk thistle, selenium and kelp as a shot-glass of mud-swill to chase with said drink.

And ultimately, trust your body. The regimen may morph one way or another because one notices something. Tune in to the little signals.
