You may not even need a multi-vitamin.
When I went to the "herbalist" (believe me I called her a witch doctor before I went), recommended by my doctor, I had no expectation that the "herbs" or whatever would do any good - just a bunch of hooey. But after 3 years and no success on regular meds for a medical condition, I agreed with my doctor that I had nothing to loose.
When I first went to her-- she did a "reading" that pretty much blew my mind. She told me what I needed to help correct my problems. I also explained that I had no energy and had to drag myself through the day and could barely get out of bed in the morning. She told me to take this Chinese Chi Tonic (tastes like sewage water). She added that I could stop taking my other supplements, including the multivitamin because I did not need it. Lo and behold, tests from my doc reveal that the herbs are indeed helping my condition.
I was one who did not believe in this stuff but it has actually helped me. I really am not a crackpot and I don't sell this stuff. This is just my experience. I would have never ventured this far into natural healing without the recommendation of my medical doctor.
Please no flames -- again this is just my experience.
