Save your money and find a nutritionist to meet with you. While there are so many herbalist etc around, it has been medically proven that taking some combinations of "natural" healing medicines can actually even be deadly.
Remember that many chemicals are going to remain in your liver. My father, who was very into the vitamins, minerals etc. died of a very rare cancer of the bile duct which very well may have been affected by years of self-medication of natural so called products.
Save your money up, see a licensed specialist first.
And there are many vitamins which are sold that are completely useless.
