FitWhey+ stands as a significant innovation in the realm of functional food formulas aimed at body composition and weight management. The foremost goal of our medical advisory board in the development of FitWhey+ was to source a high-quality whey protein devoid of genetically-modified hormones (rBST and rBGH). These hormones, still used in the United States dairy industry despite bans in other countries, have raised concerns, particularly regarding their impact on early puberty. After extensive research, our team concluded that the rigorous regulations set forth by New Zealand's Ministry of Agriculture and Forestry (MAF) lead to the production of the most pure and bioactive whey protein. The MAF's stringent policies not only ban synthetic hormones in dairy farming but also enforce specific feeding practices, environmental standards, and calf-rearing methods, all contributing to the exceptional quality of whey protein from New Zealand. Although importing this whey protein into the United States incurs higher costs, our advisory board was unanimous in its decision that FitWhey+ should exclusively contain 100% pure New Zealand whey protein for its superior quality and safety.*

Discussion

FitWhey+ is a proprietary whey protein blend sourced from the pristine environment of New Zealand, which is known for its rigorous standards in dairy processing. FitWhey+ is composed of New Zealand whey protein concentrate, L-glutamine, glycine, and taurine. This blend is certified to be 100% hormone-free, offering a high-biological-value whey protein concentrate enriched with both essential and non-essential amino acids. Recognized as the premier choice of protein among elite athletes, whey protein is linked to numerous health benefits. These include its support for a healthy body composition, the preservation of lean muscle tissue, effective glucose metabolism, enhanced feelings of fullness, and benefits to digestive health.[1-5] Its potential impact on maintaining normal blood pressure and cholesterol levels is also being explored.[3,5] Whey protein, rich in the sulfur-containing amino acids cysteine and methionine, is known to bolster immune function by supporting glutathione production within cells.[3] It is also a source of bioactive immunoglobulins resistant to breakdown in the digestive tract, offering support for intestinal immunity and a balanced inflammatory response.[3,4] Additionally, it has been noted for its lower allergenic potential compared to casein.[6]

Glutamine and Glycine, when combined with cysteine-rich whey protein, play a key role in synthesizing glutathione and neutralizing free radicals. Glutamine is vital for amino acid replenishment, particularly post-exercise or during periods of stress, and is crucial in nitrogen metabolism.[7,8] It also supports the proliferation of intestinal cells, which is important for maintaining the integrity of the gut barrier and overall intestinal health.[8] Glycine, functioning as an inhibitory neurotransmitter, is essential for collagen formation and serves as a precursor for various vital compounds, including coenzyme-A, nucleic acids, creatine phosphate, purines, bile, and several amino acids.*

Taurine, derived from sulfur-rich cysteine, exhibits various health benefits, such as stabilizing cell membranes, promoting heart health, supporting glucose metabolism, aiding detoxification processes, and facilitating bile salt production.* [9]

Aminogen®, a patented natural enzyme system derived from plants, enhances protein digestion and amino acid absorption. This boosts nitrogen retention and is beneficial for muscle mass and strength synthesis, as well as supporting thorough muscle recovery.*[10]

Medium-Chain Triglycerides (MCTs) are a rapid and efficient energy source due to their quick absorption and metabolism.

The optimal macronutrient composition is provided in each serving of FitWhey+, offering 21 g of premium whey protein; 3 g of fats, including 0.5 g from medium-chain triglycerides; and 11-13 g of carbohydrates, with 6-8 g being fiber. This balance supports a healthy macronutrient and fiber profile. Foods high in fiber are known to moderate glucose absorption into the bloodstream.[14] Additionally, both fiber and protein are recognized for their ability to enhance satiety.*[14,15]

FitWhey+ is devoid of added sugars (including fructose) and stevia, opting instead for monk fruit extract as its sweetening agent. Studies in both animals and humans indicate that drinks containing fructose may increase visceral fat accumulation.[16,17]
