Hii, I Am A Regular Gymmer...i Do Consume Whey Protein,eggs

Hii,
I am a regular gymmer...i do consume whey protein,eggs and chicken.
Which micronutrients should i add in my routine...to reduce body heat caused by the diet and indigestion.
I do get regular acne on my face and my body as well. Some of the tablets which are suggested to me by my trainer are as follows:

1 Multivitamin in morning
1 Becosule tablet preworkout
1 Evion 2 Celine postworkout
1 cod-liver oil after dinner
1 zevit before sleeping

Are these tablets safe and necessary...or can I replace them with other tablets?
Plz suggest other medications if necessary
