Weight Gain Drink
If you are looking for some sort of drink that will make you gain weight, then you are probably looking for a protein shake. Protein shakes may or may not be good for you, but gaining a lot of weight all at once is not good for you. You shouldn't gain more than a pound a day if you want to gain weight healthily.
Weight Gain Comparison
Gaining weight by using protein shakes is supposed to raise your weight by 2 to 5 pounds. This is definitely not a good and healthy way to gain weight. Doctors recommend 1 to 2 pounds instead. If you just change your diet, then you will be able to make that by the end of the week without having to buy protein shakes. You can gain 4 pounds a month and 52 pounds a year by just changing your diet by adding an extra 500 calories a day. This is much better and safer than adding up to five pounds a day.
Best Weight Gain Shakes
SportPharma's Gainer is probably the healthiest way to gain weight. Just eat your normal diet, go and work out for about thirty minutes doing weight lifting and then drink the shake. This will about right around 600 calories to your diet, giving you the extra you need to gain weight. Since you are also combining it with a workout, then you will be gaining mainly muscle mass and not fat. Don't be sad if you do gain a little fat as well. This is fairly healthy. Naturade also has one that adds 900 in four servings. It would probably be better to take only two servings a day, as this would add almost 500 calories to your diet, giving you about one pound a week.
If you are looking to gain weight and want to gain it fast then a weight gain drink or protein shake will help you to do that, but since it is unhealthy to do it so quickly, it is better to find a different way. If you are a body builder and want to gain weight fast, then you could try the protein shakes, but understand that it is not necessarily good for you.
