Yes: You can certainly take all of them without having any idea of how much money you are wasting. None of these have any benefit for a 30 year old and some recent evidence suggests some you are choosing to take can actually cause harm.

It's important to carefully read the labels of any vitamins being considered, as some may contain problematic synthetic ingredients. It's also important to check studies for the specific vitamin products they used. Some of those showing increased cancer risk, etc, have used synthetic ingredients rather than natural ones.

Why?: Why are you taking these pills? At your age, there is no need to suppleemnt with multivitamin unless you are preganant to plan to be soon. If you are taking a multi, which you shouldn't then you don't need extra vitamin c. Best to get your vitamins and minerals from fruits and vegetables. For B12 and vitamin d, eat wild salmon and then no need for fish oil. Eat healthy meals and forget pills.

Except that the soil is deficient in magnesium, and has been for over 50 years. Most people are magnesium deficient, including those on good diets. I do recommend my patients get nutrients from food, but find I have to recommend magnesium supplementation. More info: Http://drfairchild.blogspot.com/2012/12/magnesium.html

Also, I have whole families on good diets who are B12 deficient, and who require not pills, but actually shots.

Yes: Yes, it's safe to take those together. Multivits. Are a bit tricky as some of the components (fat soluble vits a, d ; e) are better absorbed with fats while minerals are better absorbed on an empty stomach, but sometimes the b vits ; zinc cause stomach upset on an empty stomach- so generally best to take after a meal. Consider additional vit d if you don't get much sun. See http://bit.Ly/1dc7vna.

As Dr. Baker knows, not all doctors agree with his conclusions. Best to avoid pills whenever possible and stick with food and sun.

And as Dr. Charlap should know, Dr. Baker and other physicians have a right to share different points of view.

Best to eat Fresh, colored Fruits & Vegetables daily, providing you with Vitamins, minerals, good quality natural water as well. Go NATURAL.

Best time : Best time to take those supplements is with food. If you notice it bothers you then split it up. Don't overdo the garlic. You may want to get close to someone and large amounts of garlic will come out in your pores and breath.
