When you're working hard to build muscle, you may be lured by nutritional supplements promoted to help you reach that goal.

Weight-gain products may impress with their promises of large muscles and a beefy, bodybuilding body. But these supplements are generally a waste of money; you can get all the protein and calories you need for weight gain from eating mostly whole foods.

Muscle Milk is a high-protein supplement used by athletes and exercise enthusiasts to help boost protein intake. This line of nutrition products includes shakes, powdered mixes and bars. As a source of calories, any one of these products will make you gain weight, if they push you over your daily calorie needs.

Weight gainers are nutritional supplements that can help you gain weight and add muscle. Weight gainers usually come in the form of powdered protein that can be mixed with water, milk or juice. If you are attempting to gain muscle, you must increase your overall caloric intake and consume adequate amounts of protein.

Many women would like to lose a few pounds, but if you'd like to put on pounds instead, you may find it to be a challenge. To gain weight, you'll need to increase your calories, and if you have a small appetite, you may want to try some other ways to boost your intake, in addition to your regular meals and snacks.

If you want to be stronger, faster or have better workouts, you might be considering a dietary supplement such as BSN Nitrix 2.0 to help push you toward your goals. According to the product description, BSN Nitrix 2.0 improves muscle performance, endurance and recovery.
