Too many supplement will probably make your body forget how to extract it from food you eat or probably your body have excess to certain vitamin or minerals which can be bad. 

The part that body forget how to extract or absorb mineral is more like my imaginative theory 

I always believe that when you use external thing to interfere with your body, then probably you interrupt with your body biology. Like when you take medication for high bllod pressure. The doctor will tell you to take once a day but no one ever monitor whether your current pressure requires you to take one or not. It just become routine and you give no time for your body to cure itself. Most modern medication use external stimulation concept without trying to cure root cause.    This is slightly off topic I guess.

Well, certain vitamin or mineral in excess to body can be bad. How much your body absorb certain mineral whether enough or not depends on the food source. I also take multivitamin but not strictly follow instruction like 1 table each morning whatever. I found a good article to read.

Zinc picolinate. Zinc good for men (iykyk), picolinate type bc it has the best absorption rate

I take vit D too

Besides those I try not to take more. Better to get nutrients from your food

Just be careful with zinc pico. Transitional metal can increase oxidative stress especially zinc pico lah. I have grayish hair transiently due to zinc pico during covid. Stop and hair color recovers
