Centrum is a fine multivitamin... but you should not be getting all of your nutrients from vitamin tablets.  Most of them should come from your food.  That's why the tablets are called "vitamin supplements".  Don't take more than the dose on the bottle... some vitamins can make you sick if you overdose.\n\nThe RDI is the recommended daily amount of a given vitamin.  So you can get whatever fraction of, say, iron, from your vitamin, and the rest from leafy greens like spinach or red meat.  Ditto for other things.\n\nSince you are trying to conceive, I suggest buying a specifically prenatal vitamin... you need folic acid in this time before pregnancy.  You should also talk to a doctor about having the optimum diet for you and your baby.  Best of luck!

Before you take anything, you should probably have a check-up and blood work (if you haven't already) to rule out anemia and other things and make sure that vitamins is all you need.  If you eat well and get enough rest, being tired can be a sign of other things that taking vitamins won't cure.

You can take vitamin c and a mutli-vitamin with milk.  Your body needs magnesium to absorb calcium so you should actually absorb the calcuim in milk better with most multivitamins.

Your interest in supplements is a sign that you want to take charge of your health.  That is a good thing!   Eating the right quantity and quality of food should be all that you really need, so I would start with good nutrition.  However, you can supplement to help your body through an illness or if you feel that you are lacking something.  If you do take a supplement, make sure it is of the highest quality, otherwise you are just wasting your money.  Try shopping at a food cooperative, a place like like Whole Foods or a reputable health food store.  The first link offers a lot of information and guidelines to answer your question.  The second link will allow you to investigate specific supplements. \n\nhttp://ods.od.nih.gov/pubs/partnersbrochure.asp\nhttp://nccam.nih.gov/health/supplements.htm\nhttp://www.coopdirectory.org/\nhttp://www.wholefoodsmarket.com/healthinfo/index.html

Take 2000 mgs of Vitamin C all at once. You should notice a difference in about 20 minutes.  If you don't, take another 1000 mgs of Vitamin C.  If it gets stuffed up again, do this again.\n\nDr Linus Pauling, who won a Nobel prize, used to take 10,000 mgs of Vitamin C per day and 20,000 mgs per day when he had a cold coming on or a flu.  He lived to be around 95 years old and took care of his ranch near Big Sur until he died.  If it is good enough for him, it should be good enough for us.\n\nI have been taking a minimum of 3000 mgs of Vitamin C for 35 years.  I am fine.  I take no medical drugs.  When I have a cold, I take 3000 mgs every 3 to 4 hours to keep my nose from running and to stop sneezing so much.  \n\nI rarely get a cold because as soon as I notice a cold coming on, I immediately (within an hour, if possible) take 3000 mgs of Vitamin C and then again in 3-4 hours and if I don't forget, I take another 3000 mgs of Vit C at bedtime. In most cases, I never get that cold.  If I don't take Vitamin C within the hour from when I first notice a symtom of the cold, it is likely that I will have to suffer through the cold but taking the Vit C every 3 - 4 hours helps to make me less miserable.\n\nzhebee

I have been on an 850 to 1000 calorie diet for 4 months now, and I've lost 50 pounds.  I spoke with the 5 Dr.'s I work with and my family doctor before I started it, and they all said that it is safe, but to take multi-vit.'s because it is very hard to get all your food groups in your meals.  Exercise can be anything from just sitting in a chair and making circles with your legs and arms, to walking.  You can start out slow, that's no problem.  Don't overdo it, but do as much as you possibly can.  When you start to lose weight, you'll see how easy it is to get up and move around, therefore you can do more exercises.  Drink at least 8 8oz. glasses of water everyday, and fill up with fiber.  It helps you feel fuller longer.  This diet DOES get easier as you get on it, because your lifestyle changes, and you just get used to it.  Trust me, you can do it!  I wish you the best of luck with this.  After the first month, it will get easier and easier.  One thing with low-cal diets is that it lowers your metabolism, but the exercise actually keeps it up, so you kind of even it out.  Sit in a chair and do lifts with weights (5 or 8 pounds), that will burn calories, and build muscle.  The more muscle you have, the more fat you burn.  Hope it works for ya!

Natural is always better, synthetic multi-vitamins can, at best, replenish the required quantity, it can't be used as a supplement to your normal intake of vitamins through natural sources.

The Journal of the American Medical Association (JAMA) states that everyone should be taking a multivitamin for prevention of diseases. Mainly because most of the foods we eat nowadays do not contain the nutrition they once did.

I have to disagree with lots of what the last guy said but he is correct when he says stick to a healthy diet. Remember, suppliments (The Natural Ones) are just that to suppliment your already existing diet. Whey protien is good, also creatine naturally occurrs in your body and that suppliment will help your performance. L-Glutamine will help your muscles repair themselves. Other than those as long as your diet is balanced then a multivitamin can not hurt.

Have you been exercising consistently?  If you are just starting out, then you will feel exhausted for a couple of weeks.  Your body will adapt.  And even though you eat well, you should take a good multi-vitamin.
