Optimum Nutrition 1098370 Editorial Review
Serious Mass Vanilla Protein Powder is a supplement designed to help users gain weight by increasing their calorie intake. The powder contains 50 grams of protein per serving with essential vitamins and minerals. The product is also available in chocolate flavour with the same nutrition profile. The product is beneficial for those who find it hard to eat more protein after a workout. The vanilla flavour has a nice taste and does not overpower, although adding fruit or nuts to the shake makes it more palatable. However, some users did not enjoy the taste of vanilla and found it difficult to drink. The powder is gluten-free, and the expiry date depends on the batch currently in stock. The product is not suitable for vegans or those who are lactose intolerant.
