FitPlant+ is a nutritionally dense shake mix, perfectly suited for those who are sensitive or allergic to soy and dairy, or for individuals in search of a superior plant-based protein source. At the heart of FitPlant+ is Fitties Vegan Protein, a natural blend of pea and rice proteins. Enhanced with Aminogen®, a plant enzyme that improves protein digestibility and absorption, and KiOtransine® chitin-glucan, an innovative fiber that bolsters the body's antioxidant mechanisms. This vegan formula is free from sugar and stevia and comes enriched with a spectrum of micronutrients. These include high-potency vitamins C and B12, bioactive B vitamins, and Albion® TRAACS® chelated minerals, known for their real amino acid chelate system, ensuring optimal nutrient absorption.*


Fitties Vegan Protein, a unique blend crafted by Fitties, combines easily digestible pea protein isolate with glycine, taurine, rice protein concentrate, and L-glutamine, forming the foundation of FitPlant+. The addition of Aminogen in this blend is specifically designed to boost protein digestion and absorption.[1] The synergistic use of pea and rice proteins in FitPlant+ achieves a complete amino acid score of 100%, aiding in protein metabolism and the promotion of a healthy body composition.*[2]

Protein plays a crucial role in repairing cells and tissues, synthesizing hormones and enzymes, and various metabolic activities. It is particularly vital in preserving lean body mass during periods of increased physical activity. Evidence suggests that protein supplementation is a key factor in augmenting fat-free mass and promoting exercise-induced fat burning. Research shows that participants consuming approximately 80 g/d of protein, as opposed to around 59 g/d, saw a notable rise in fat oxidation and fat-free mass, coupled with a decrease in fat mass and overall body fat percentage.[3] Numerous studies highlight that a higher intake of protein can enhance feelings of fullness[2,4-6] and reduce food consumption in later meals.[7] A specific study pointed out the advantages of pea protein over milk protein in terms of satiety and the duration between meals.[8] Furthermore, pea protein has been shown to stimulate the release of cholecystokinin and glucagon-like peptide 1, two gastrointestinal hormones that influence appetite regulation.*[9]

Pea protein is not only a satisfying and adaptable protein source but also beneficial for cardiovascular health. Animal studies have demonstrated its positive impact on lipid management by influencing gene expression, specifically by increasing genes related to hepatic cholesterol uptake and decreasing those associated with fatty acid synthesis.*[10,11]

FitPlant+ incorporates Chitin-Glucan to support antioxidant activity and cardiovascular wellness. This unique, gluten-free fiber, comprising chitin (N-acetyl-D-glucosamine) and beta(1,3)-glucan, has been studied for its role in oxidative balance and artery health, crucial for cardiovascular well-being.[12,13] A 12-week animal study showed that chitin-glucan is beneficial for cardiovascular health by maintaining healthy arteries, reducing cardiac superoxide anion, and liver malondialdehyde (oxidation indicators), and boosting superoxide dismutase and glutathione peroxidase activity.[12] Human studies have also yielded significant positive outcomes. In a six-week, multicenter, randomized, double-blind, placebo-controlled study with 130 participants, it was observed that 1.5 g/d of chitin-glucan significantly maintained LDL cholesterol within a normal range, and 4.5 g/d notably supported the body's natural antioxidant systems and the oxidative balance of LDL cholesterol.[13] Each serving of FitPlant+ provides 2.25 g of chitin-glucan.

Micronutrient Support: FitPlant+ offers a balanced array of vitamins, minerals, and antioxidants, essential for supporting the body's extensive metabolic processes.[14] It includes bioactive forms of B vitamins like riboflavin 5’-phosphate, pyridoxal 5’-phosphate, methylcobalamin, and 5-methyltetrahydrofolate as Quatrefolic®.*[15]

Sugar- and Stevia-Free: FitPlant+ is sweetened with monk fruit extract, avoiding the use of sugar or stevia. Studies in both animals and humans indicate that excessive consumption of added sugars can increase adiposity, disrupt lipid regulation, and heighten cardiometabolic risk.*[16-20]

Glutamine, an essential amino acid, is crucial for replenishing amino acid stores post-exercise or stress.[21] It also supports the proliferation of intestinal cells, thereby maintaining gut barrier functionality and intestinal health.*[22-24]

Inulin, a soluble fiber, is fermented by colonic bacteria into short-chain fatty acids, which positively influence lipid metabolism and promote healthy colon transit time.*[25,26]
