DHC Vitamin B Mix

My sister recommends "DHC Vitamin B Mix" to me.
"Mix" means included many kinds of vitamins, B1、B2、B6、B12 & etc.
It's good for skin, heart and boosts up antibody.
Because my diet is unstable, so I bought it for my daily supplement.
Unluckily, I found that vitamin B has side effects,
it's not good for my lungs, so I will take it after meals.
You can purchase it at any DHC shops or online shop if you want to try it.
