Can I mix vitamins and herbal remedies?

Hi, I’ve been using vitamins for a long time. They are helping me, but I still have problems with concentration. Please tell me, can I mix vitamins and herbal remedies?

Hi, I am using multivitamin pills for a long time, because I don’t eat too much fruit and vegetables. Half a year ago, I was studying for my exams, and I couldn’t concentrate. Vitamins were making me feel better, but they didn’t help me focus and concentrate on studying. I went to my friend who is nutritionist, an she recommended me gingko biloba tablets. I told her that I’m already using vitamins, and asked her if they could be mixed with herbal remedies, and she said that this combination won’t be a problem. However, she told me never to mix herbal remedies with medicines, because they could be a risks of drug interactions. She was right, I never had a problem due to mixing vitamins and herbal remedies. If you’re still not sure about this, call a pharmacist and consult with him/her.
