All-Natural, No Added Sugars

FitBoost+ employs purely natural components instead of relying on ephedra or synthetic energizers to enhance workout efficacy. It boasts a low carbohydrate content with only five grams and absolutely no sugars. Opting for natural flavorings and stevia as alternatives to sugar and other carbs, it sidesteps the common sugar rush found in numerous energy drinks. Additionally, FitBoost+ is free from synthetic colorings.*


Taking ATP (adenosine triphosphate) orally, especially when combined with resistance training, has been observed to yield performance-enhancing results.[1] PEAK ATP, a unique patented version of ATP disodium, is evidenced through human research to boost muscle growth, strength, power, and recovery efficiency. Its effectiveness stems from enhanced muscle excitability, better blood circulation, and amplified anabolic signaling.[1-4] PEAK ATP in FitBoost+ is instrumental in aiding athletes in reaching new heights of performance.*

Studies indicate that a daily intake of 400 mg PEAK ATP can elevate ATP levels post-exercise and augment athletic prowess after multiple sprint cycles. It significantly boosts vasodilation and blood flow post-acute arm exercises.[5,6] Research including a double-blind, placebo-controlled, crossover study demonstrates that 15 days of 400 mg PEAK ATP supplementation “tended to alleviate muscle fatigue and enhanced muscle low-peak torque in exhaustive exercise sets.”[1] Another study involving resistance-trained participants over 12 weeks revealed increased strength (147%), power (30%), lean body mass (100%), and muscle thickness (96%) with PEAK ATP, along with a decrease in body fat compared to the placebo group.[3] These studies also suggest PEAK ATP's role in curtailing performance dips commonly associated with overreaching.[3] Purpura et al. in a randomized, double-blind, placebo-controlled trial (n=42) discovered that two weeks of 400 mg PEAK ATP supplementation prevented declines in ATP and its metabolites caused by exercise, and enhanced peak power and muscle excitability.*[7]

Creatine Monohydrate

Creatine supplementation elevates creatine levels in muscles, boosts energy generation, mitigates muscle tiredness, and diminishes lactic acid production. Notable improvements in body mass, fat-free mass, oxygen uptake, sprint capability, weightlifting performance, and overall exercise capacity have been seen following creatine supplementation.[8-10] In FitBoost+, the synergistic impact of caffeine, creatine, and amino acids has been linked to advancements in time to exhaustion (TTE) and peak velocity (PV) during physical activities.*[11]

Caffeine Pterostilbene Co-Crystal

The caffeine pterostilbene co-crystal is an inventive compound that merges caffeine with pterostilbene, a bioavailable variant of resveratrol, forming a novel co-crystal structure. This structure influences how caffeine is utilized by the body, potentially offering benefits over standard caffeine alone. A rat study (n=6) showed the half-life of caffeine from this co-crystal to be eight hours, compared to only three hours for ordinary caffeine.[12] In a preliminary four-week, single-blind, crossover human study (n=12), 232 mg of caffeine pterostilbene co-crystal (yielding 99.76 mg of caffeine) was compared to 100 mg of ordinary caffeine. The study revealed about 30% slower absorption and 30% more bloodstream caffeine from the co-crystal. Notably, serum caffeine from the co-crystal was 51% higher after six hours compared to ordinary caffeine.*[13,14]

These findings suggest longer-lasting effects of caffeine from the co-crystal than regular caffeine, potentially allowing for reduced overall caffeine consumption. The extended half-life and slower absorption of caffeine from the co-crystal may also lead to a more gradual decline, avoiding the typical crash associated with conventional caffeinated products. While these initial results are encouraging, further extensive studies are required to confirm these benefits and assess if they translate to prolonged energy effects. Interestingly, chlorogenic acids in coffee have been observed to positively impact human fecal microbiota, including Bifidobacterium species, potentially benefiting overall health.*[15]

Herbs and Amino Acids

FitBoost+ combines caffeine pterostilbene co-crystal with various herbs and amino acids, including green tea extract, coffee fruit extract, taurine, and L-arginine alpha-ketoglutarate, in a proprietary blend. This blend is crafted to enhance the functions of caffeine pterostilbene co-crystal. Additionally, when taken in significant doses, some of these individual components are known to contribute to mitochondrial biogenesis and positively affect exercise performance.*[16-18]

Electrolytes and Antioxidants

Electrolytes like sodium, potassium, and magnesium are crucial for energy production, nerve transmission, muscle contractions, pH balance, fluid balance, and more. Excessive sweating and heightened metabolic activity can necessitate the replenishment of these vital minerals and an increased need for antioxidants. FitBoost+ offers 130 mg of sodium, 280 mg of potassium, and 150 mg of magnesium per serving. To aid in combating free radicals, it also provides 500 mg of vitamin C as four mineral ascorbates, along with natural vitamin E, selenium, green tea extract, and s-acetyl-L-glutathione (SAG). SAG is a stable form of glutathione that can penetrate mitochondrial membranes, enhancing mitochondrial function and reducing reactive oxygen species.*

B Vitamins

The B vitamins in FitBoost+ are presented in activated forms to ensure optimal bioavailability and utilization. These water-soluble nutrients serve as vital parts of coenzymes in the complex biochemical processes that convert food into glucose and ATP, the energy currency of cells. Vitamin B12 in particular collaborates with folate in red blood cell production and aids iron in its role of transporting oxygen to all cells, including muscle cells, for energy production.*
