Prenatal Vitamins

I am looking for a list of prenatal vitamins that have these elements that does not contain fish oil:

• 4,000 of vitamin A : I am unsure if I really want Vitamin A
• 250 mg DHA
• 800 and 1,000 mcg (1 mg) of folic acid
• 400 IU of vitamin D
• 200 to 300 mg of calcium
• 120 mg of vitamin C
• 1.5 mg of thiamine
• 3.4  mg of riboflavin
• 2.6 mg of pyridoxine
• 17 mg of niacinamide
• 3 mg of B1
• 20 or 25 mg of B-6
• 2.2 mcg of vitamin B-12
• 30 mg of vitamin E
• 15 mg of zinc
• 2 mg of copper
• 90 mg of iron
• 50 mg Docusate sodium – stool softner

I am curious what MetaFolin is and how important is magnesium?  I am cross referencing vitamins with my insurance coverage to make sure I have utilized all my resources in finding a prenatal vitamin that I want to take.

Thanks,
Vitamin Shopper
