Serious Mass - all-in-one blend that is a source of protein and contains a high dose of carbohydrates, which will help to significantly increase energy intake
Serious Mass is a packed gainer that will help effectively increase energy intake, for example, during the bulking phase when it can be challenging to consume enough calories. The base of the mixture is a good dose of quality carbohydrates. In addition, thanks to the whey concentrate, the gainer is also a source of proteins that contribute to the growth and maintenance of muscle mass, as well as to maintaining healthy bones. But the ingredients also include creatine and a variety of vitamins and minerals to help with overall health and vitality.
It contains vitamin B1 (thiamine), which supports proper heart function. It also contributes to normal energy metabolism. Vitamins B2 (riboflavin) and B3 (niacin), in turn, contribute to the normal functioning of the nervous system. Vitamins B6 (pyridoxine), B7 (biotin) and B9 (folic acid), in turn, play a role in maintaining proper mental function. However, not to be missed is vitamin B12 (cobalamin), which contributes to the reduction of both fatigue and exhaustion. In the composition, you will also find vitamin C (ascorbic acid), which supports the proper function of the immune system. In addition, it also contributes to the optimal production of collagen for the proper function of bones, cartilage, blood vessels and skin. However, we can't forget vitamin E, which contributes to the protection of cells from oxidative stress.
Minerals also contribute to optimal body function. Magnesium, for example, supports proper muscle and bone function. Zinc, in turn, contributes to normal cognitive functions. In addition, it supports the maintenance of normal testosterone levels in the blood. Iron also plays an important role, which contributes to the normal production of red blood cells and haemoglobin and supports oxygen transport in the body. Creatine also plays a role, helping to boost performance during short intervals of intense training.
As you can see, Serious Mass is packed with not only macronutrients but also micronutrients to help with overall body care. Plus, it will win you over with its great taste and quick preparation, making it an ideal addition to the pack of all strength athletes and fitness enthusiasts. Enjoy this gainer between meals, after training or before bedtime.
