If you are looking for a vitamin to add into your diet you have to make sure you get the right one. There are a ton of vitamins out there that offer the "Daily Recommended Value" but for most of us, that's no where near enough to supply and power our bodies. GNC's strongest and in my opinion best vitamin is Ultra Mega Gold. This vitamin is packed full of vitamins and minerals to give your body what it needs to function at its very best. At only around 25 dollars it is a very good investment to make for your body and your health. These are one of my favorite vitamin supplements out there, they give me so much energy all throughout the day and help me focus. These vitamins are a great start to a weight loss program as they will get your body in the optimum fat burning zone vitamin/mineral wise. I know people who have lost 10 pounds just by adding this vitamin to thier normal diet. Don't waste money on gimmicks that will help you feel better and lose weight just pick up a great multivitamin and be at your best everyday.
