BOOST Very High Calorie Nutritional Drink – Helps Weight Gain & Maintenance - 530 Calories - 26 Vitamins & Minerals - 22 g Protein - Calorie-Dense Nutritional Drink - Chocolate - 8 fl oz (Pack of 24)

We bought these drinks for my teenage son, who has been severely underweight since elementary school. When nothing else worked--these do! He has gained five-ten pounds in the last month or two, and I have hope he'll reach a healthy weight for the first time in years. In our case, a naturally high metabolism, stimulant medication, limited safe foods, and genuinely forgetting to eat all worked against him. These high-calorie shakes meet his taste and texture requirements and allow him to get protein, fat, and calories without stopping to eat.

These high-calorie drinks have really been a lifesaver. My husband enjoys the rich chocolate flavor, and they provide him with all the protein, vitamins, and minerals he needs for his regular diet. They are not clumpy and become smooth and creamy when you shake them up. They have 13g of added sugar, so they may not work for everyone. Although he's lactose intolerant, the ingredients don't upset his stomach or cause diarrhea. He drinks three to four of these a day, so the extra calories are a crucial part of his diet. I subscribe regularly, but I often have to order some bottles in between deliveries because he sometimes drinks more than I expect. Fortunately, that's not an issue—if I place my order by midnight, it arrives well-packaged and on time the next morning, based on when I ordered the night before.

I am on an extremely limited diet. I need to add many more calories to my diet to keep from losing so much weight. This Boost has the highest calories per serving that I have found among the choices. A bit pricey but worth the money for me. Not a lot in the bottle but I add one of my protein drinks to it. chocolate and strawberry mixed are the best!

This is probably the most calorie dense drink out there. It packs 530 calories into 8 fl oz (237mL). It's certainly will make you feel full having essentially the same amount of calories as a full, hearty meal. The liquid itself is viscous. Probably more viscous than any other liquid you might conceivably consume. It also seems to have quite the assortment of vitamins in it, which is quite nice for supplementing your diet. This is especially true if the majority of what you consume is this drink as you would otherwise be depriving yourself of necessary vitamins and nutrients. So, speaking of the benefits, overall, I would say that it's quite satiating and does what it sets out to do. Now, that does come at a cost. At just over $50USD(at the time of writing this review, it's quite expensive. If you're like me, then your relatively light diet has been quite affordable, so this is quite the increase in my foodstuffs purchases. Secondly, it is absolutely vile. It tastes as if you're drinking cooking oil that had a chocolate bar sitting in it. I have to hold my breath while I drink it after which I chase it down with another beverage and then something to cleanse my palate. I repeat this about 2 or 3 more times before I finish it. It would not be an exaggeration to say that I have an easier time drinking liquor than drinking this. Though I suppose there is no way to squeeze 530 calories into this volume of liquid and have it taste good, so you gotta take the good with the bad. Overall, it's calorie dense, filling, and has a lot of vitamins, but the taste is offensive at best and drinking it down is a process thanks to its thick composition.

Tastes great( chocolate)

Changed the game with this, they are pretty expensive when you drink a box within a week in a half but they are worth it! I’ve gained 6 pounds in about 2 weeks! I literally drink no less than 3-4 a day. I’ve went from 94 pounds to 100 faster than ever will continue to be my #1 weight gainer!

Our daughter was diagnosed of eating disorder and the dietitian recommended this brand with high calories. I aliquoted it and make it around 400 calories per serving and three servings per day. We restored her weight (~20Ibs) and got her energy and mental stability back in about two and a half months. I truly appreciate there is such a product available over the counter. Now, she is off boost and eats normally. I would recommend this to anyone without reservations. But, I do hope we would not need it anymore. By the way, my daughter told me that the chocolate flavor is a bit better than vanilla one but both don’t taste good. But we told her it is a medicine and she could die without it. It worked for us.

Using to gain weight. Great taste and seems to be working. Highest calorie drink I could find.
