1. Answer: A. The American Medical Association recommends that every adult take daily vitamins for their health and wellness. Every adult should at least take a multivitamin. In certain circumstances, children could also benefit from taking vitamins, although the AMA says the primary focus should be on feeding kids healthy foods.
2. Answer: B. Vitamin D helps increase your body's absorption of phosphorous and calcium. These two nutrients are extremely important for building and preserving strong bones. Your body receives Vitamin D through fortified milk, cheese, fatty fish and exposure to sunlight.
3. Answer: Vitamin C. Vitamin C is found in many fruits and vegetables, and it helps bolster your immune system. And Vitamin C the pop star is famous for the hit singles "Smile" and "The Itch."
4. Answer: A. Fish. According to the Food and Drug Administration, your heart may benefit from cutting saturated and trans fats from your diet and adding healthful omega-3 fatty acids, such as DHA and EPA. Omega-3 fatty acids also support your brain, eyes and joints.
5. Answer: B. Calcium. While your best bet is to get calcium from milk and dairy products, it can be difficult to get enough calcium from your diet alone. Doctors often recommend taking calcium supplements, though there has been some disagreement in the medical community about how much calcium your body needs.
6. Answer: A. Vitamin A (also called Retinol). Vitamin A is important for good vision. It also bolsters your immune system, has an impact on reproduction and impacts numerous other bodily functions.
7. Answer: D. Folate supplements are generally recommended for all women of child-bearing age because they help prevent birth defects. Extra folate may be helpful for other people too though, because there is increasing evidence that it can lower your risk for heart disease and colon cancer. Folate deficiency may also lead to anemia.
8. Answer: A. Antioxidants. An antioxidant supplement is valuable for people who exercise frequently. Training increases the production of free radicals in the body, so if you're starting a fitness program, then you may want to take an antioxidant.
9. Answer: B. Probiotics. Recent research has uncovered the many benefits of these beneficial bacteria. They can help ease tummy troubles and other digestive problems, which can result from diet, stress, travel, certain medication and the environment. For dieters, probiotics supplements encourage a healthy metabolism, especially when you begin eating new, healthful foods.
10. Answer: C. Green Tea. It is the naturally occurring caffeine in the tea that boosts energy and the EGCG that supports a healthy metabolism. Green tea also contains powerful antioxidants and polyphenols. Having plenty of energy is the key to staying motivated to exercise.
11. Answer: A. Fiber. If you're on a healthy diet plan but still feeling hungry, then a supplement that contains fiber may help you feel fuller longer.
12. Answer: C. 70 percent. Believe it or not, 70 percent of your body's immune system is located in your intestinal tract. That's why it's so important to balance your intestinal tract with probiotics supplements.

I got an 11 out of 12. DId not know about taking anti-oxidants if you exercise frequently, which I do. I may get my vitamins out again. The problem is I bought some very high quality multi-vitamns but they are not pleasant to take due to the smell/taste. NOTE: I am gluten intolerant so I bought vitamins that state there is no gluten in the ingredients.

I got 9 of 12. I did not know about antioxidants, and I should have known about vitamin A and green tea.

I'm happy to say I only missed one!! I'm an avid vitamin taker and have been for many years...makes a big difference in my life. I'm 50 but everyone mistakes me for 40...sometimes even younger!

I got 12 out of 12! I did have to stop and think about #6 (I kept wanting to use Vit. K for something). I have taken Vit.supplements for years because of my crazy schedule (being a mom, full time employed and went back to school for my bachelors and about to finish my Master's - Whoo Whoo), I do not always eat right.

I got 12 out of 12, but I must admit a few were lucky guesses. I have RA which is and auto-immune disease. The connection between the intestinal tract/probiotics and auto-immune system may give me something to work with

I got 9 out of 11: I fail to see how knowing an actress's name is nutritional knowledge. Didn't know about the intestinal tract, and had a memory blib on eyesight. Not too bad!!

I got 11 out of 12 too, not knowing the anitoxidants thing if you work out a lot. I don't, which is probably why haha. I exercise moderately, just not consistantly, but at least I learned something new.

11 of 12. 70% of the immune system is in the intestines? I had no idea. Otherwise did well. Great quiz, always helps to review why we do what we do. Will be giving this quiz to some of my less-informed family and friends.
