Loosing 0.2 to 0.5 Kg Per Day?

Hello. By the side effects of some supplements (like normal vitamins/herbs) I am losing around 0.2 Kg per day or 1 kg per day. Last week when I started to use them, I was around 116.5 Kg but now I am around 111 kg. I am using these supplemets for another purpose but the side effect on me is weight loss. It is not a general side effect. When I am sleepy I have some vertigo. Would losing that fast weight give harm or will it stop slowly somewhere and need not I worry? or later the weight will increase worse than before because of imbalanced weight loss? Tweet
