Boost Very High Calorie Chocolate Nutritional Drink – 22g Protein, 530 Nutrient Rich Calories, 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 tried the chocolate option for about 2 months in hopes to gain more weight. I got these specifically because they’re very high calorie and contains less sugar than other meal replacement shakes. Within that time, I’d drink 1-2 bottles daily, skipping a day or two on the weekends. Eventually both my partner and I noticed that I was actually putting on weight! Prior to drinking these, you could see my ribs, Now, nearly two months of drinking these consistently, my ribs are no longer visible!! Now as for the taste, I’ve only tried the chocolate flavor, but I think it tastes pretty good when refrigerated. However, I have a sensitive stomach and found it a bit difficult trying to drink these on its own. The consistency is quite thick, which may be because one of the top ingredients is canola oil. I recommend drinking these with a small meal or snack to make it easier to drink. Another thing I noticed is that my nails have gotten stronger since drinking these as it contains Biotin. Plus I feel like it’s also helped boost my immunity as the shake also contains Vitamin C and Zinc, which is a great bonus. TLDR: Get this if: you’re looking to gain weight in the next couple months, don’t mind the thick texture and that it contains canola oil.

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!

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!
