Vitargo S2 is the super-soluble form of Vitargo, a patented, molecular carbohydrate with ZER0 SUGAR and -all- endurance. Only Vitargo's low osmolality, molecular carbohydrate form moves through the stomach more than twice as fast as the carbohydrates (e.g. maltodextrin and sugars) found in other sport drinks and powders.* That means faster carbohydrate digestion and absorption into the body.* It also means no bloating or that "heavy stomach" feeling common to ordinary carbohydrate-based products.* Furthermore, Vitargo S2 IVg technology is the only product of its kind that delivers carbohydrate to muscle and the rest of the body after exhaustive exercise and to accelerate glycogen refueling and recovery.*

Vitrago - when consumed at rest - is able to transit out of the stomach twice as fast as ordinary carbohydrates, many of our elite and pro athlete users take Vitargo S2 before or during training/competition or at half-time, between periods, on the bench and while transitioning between sports (e.g triathletes).*

2021 Optygen HP New and Improved byFirst Endurance 2021 Optygen HP now with Ashwagandha Root is the strongest endurance formula available

In-Stock and Ships Same Day - PSNE12F

The all-new OptygenHP formula features 23% improvement in endurance capacity and a significant increase in energy (ATP) production. Athletes who participated in these studies were able to replenish glycogen faster, which leads to improved recovery and improved performance on back-to-back workouts and during heavy training. In addition, subjects experienced less muscle inflammation after high-intensity exercise, resulting in less soreness and faster recovery.

First Endurance introduced the world to Optygen back in 2002. Since then, there have been a number of additional studies done that show Optygen reduces cortisol levels. By modulating cortisol, athletes experience better recovery, an increase in VO2, improved oxygen utilization and enhanced performance.

The new OptygenHP now delivers 50% more beta-alanine. A 2012 study evaluated the effects of beta-alanine supplementation on VO2max, time to exhaustion and lactate concentrations. Subjects supplemented with beta-alanine for six weeks. The group experienced a significant increase in VO2max, an improvement in time to exhaustion and lactate utilization. The study concluded that beta-alanine supplementation can reduce lactate concentrations during exercise and thus can improve exercise performance in endurance athletes.

Dosage recommendations: Take 4 capsules daily with a meal.
