Glycersize
Also known as: Glycerin, Glycerine, Glycerol
Overview
Glycerol is a naturally occurring sugar alcohol that plays a crucial role in carbohydrate and lipid metabolism. It is primarily recognized for its hyperhydrating capabilities, which can enhance endurance performance by mitigating dehydration and improving thermoregulation. Glycerol supplements are particularly beneficial for athletes engaged in endurance sports, especially under hot conditions. Various formulations exist, with GlycerSize being a stable version that minimizes clumping. Research on glycerol supplementation is extensive, with studies examining its effects on hydration and exercise performance, reporting varying degrees of effectiveness.
Benefits
Glycerol supplementation is associated with several evidence-based benefits. Notably, it can increase total body water and improve muscle fullness, significantly enhancing endurance performance by delaying dehydration and lowering heart rate during exertion. Studies indicate that it can prolong time to exhaustion by up to 24%. Moreover, glycerol supports thermoregulation, particularly when combined with other supplements like creatine. These effects are most pronounced in athletes partaking in endurance activities in heat, with a significant body of research validating its efficacy, despite variability in individual study results.
How it works
Glycerol acts by creating an osmotic gradient that facilitates the movement of water into the bloodstream and muscle tissues. This enhances hydration status and counters dehydration during physical activities by primarily influencing extracellular fluid compartments. Consequently, glycerol helps maintain blood volume and promotes optimal thermoregulation, improving exercise performance.
Side effects
Glycerol is generally considered safe when taken appropriately, but it may cause gastrointestinal upset if consumed in excessive amounts without sufficient water intake. Common side effects include nausea, diarrhea, and bloating. While no uncommon or rare side effects have been documented, caution is advised for individuals with pre-existing gastrointestinal disorders. There are no significant drug interactions reported, and no known contraindications, but individuals should monitor for any potential adverse reactions.
Dosage
The minimum effective dose of glycerol is approximately 1 gram per kilogram of body weight, with an optimal dosage range between 1 to 2 grams per kilogram. Higher doses should be approached with caution as they may lead to gastrointestinal discomfort. Glycerol is best taken 1-2 hours before exercise, accompanied by adequate hydration. GlycerSize, a more stable form of glycerol, is particularly recommended for use due to its reduced tendency to clump.
FAQs
What should I consider when using glycerol?
Ensure adequate water intake to minimize gastrointestinal issues when using glycerol.
Is glycerol safe for everyone?
Glycerol is generally safe but should be used with caution by individuals with gastrointestinal issues.
When is the best time to take glycerol?
It's recommended to take glycerol 1-2 hours before exercise for optimal benefits.
What results can I expect from glycerol supplementation?
Expect improvements in hydration and enhanced endurance performance during exercise.
Can glycerol help with muscle strength?
Glycerol is primarily used for hydration and endurance and does not directly enhance muscle strength or power.
