Look no farther than Optimum Nutrition's Serious Mass for a delicious way to fuel your mass gains and recovery. Serious Mass is a meal replacement shake with 1,250 calories and 50 grams of protein that's meant to be consumed after each exercise session. It also contains half of the required daily amounts of vitamins and minerals, including calcium, iron, vitamin A and chromium, for overall better health.

Optimum Nutrition Serious Mass Vanilla contains a precise combination of proteins produced by a unique, multi-step protein system that delivers a steady stream of amino acids to the body for up to eight hours after consumption.

Protein is not only essential for muscular growth; it can also help prevent illness, weight gain and fatigue. It's no surprise that with both of these ingredients, you'll find yourself reaching for a gallon of milk. However, if you don't have a lot of time to change your diet or aren't sure what would work best for you personally, this isn't the case.

Contains All Essential And Non-Essential Amino Acids

The most plentiful amino acids in muscle tissue, BCAAs, are included in Optimum Nutrition Serious Mass. They're responsible for keeping muscle from breaking down and aiding recovery after exercise. With 24 grams each serving, you'll never have to worry about running out of BCAAs again.

Improves Recovery Time After Workouts

Serious Mass is a protein shake with 250 grams of carbohydrates per serving, which will help you train even more complex than a normal protein drink. When carbs are eaten, they are converted into glucose via circulation before being stored as glycogen in the muscles, liver, and bloodstream.

Promotes Muscle Gain

Serious Mass also includes a precise combination of proteins generated from a unique, multi-stage protein system that provides the body with a steady supply of amino acids for up to eight hours after ingestion. This is aided by an enzyme known as Aminogen, which helps your body absorb the necessary amino acids in this supplement.

500 Mg Glutamine

The majority of the previous studies have focused on the effects and efficacy of protein supplements to increase muscle mass, reduce body fat, and improve performance. Protein supplementation may be helpful for those who are recovering from injuries or surgery or suffering from chronic disease due to their ability to promote muscular regeneration.

Contains No Fillers, Added Sugars

Optimum Nutrition Serious Mass shakes don't contain any fillers or added sugars. They're also gluten-free, which helps keep your digestive system healthy. Optimum Nutrition Serious Mass contains two types of natural sweeteners: fructose and sucralose (Splenda).

25 Vitamins And Minerals Plus Creatine And Glutamine

Serious Mass contains several of the minerals and vitamins you require daily. Each serving contains the following: calcium, iron, and zinc which helps in bone strength and building muscles; phosphorus and magnesium to help with healthy bones and teeth; vitamin D for proper absorption of calcium; thiamine (B1) to support brain function; riboflavin (B2) necessary for body growth and cell reproduction; niacin (B3) to provide energy and keep the digestive system healthy; vitamin B12 for metabolic functions, red blood cell development, and contributes to brain function; folic acid helps in the formation of new cells.

The vanilla flavour will have you thinking you're in a bakery. It's combined with a delicious, naturally and artificially flavoured vanilla drink that just shouldn't be missed by anyone looking to add weight in a hurry.
