Marked Nutrition is the supplement company backed by the Hollywood superstar Mark Wahlberg. The fitness icon recently saw an increase in interest from the community earlier in the year with the release of the Michael Bay film, Pain & Gain. A movie that saw not just Wahlberg show off his physique, but the George Farrah trained Dwayne the Rock Johnson display how much time he puts into his body. Getting back to the topic of today, Marked Nutrition is a small brand featuring seven different products that have just been introduced to another, taking the range up to a total of eight. Joining the straightforward line stocked by only a handful of retailers like GNC, Drugstore, and Walgreens, is a new protein formula simply titled Protein Shake. The supplement is a premixed carton RTD available in chocolate and vanilla, the same two options listed for the brand’s bottled edition of Protein Shake. However the new product does have some differences with less protein, significantly less carbohydrates, and roughly the same amount of fat. The cardboard Marked Protein Shake should currently be on it’s way out to stockists, as it has already shown up in a couple of places. Despite the fact that it is not listed on Marked’s official website.
