Creatine is one of the most well-researched supplements. Creatine is known for its numerous benefits on muscle strength, performance, and overall health. Our body's ability to produce creatine declines dramatically with age, which contributes to muscle loss, reduced strength, and slower recovery in adults. Here are the main advantages of Creatine, supported by reputable sources:
1. Increased Strength & Power Output; ATP Production: Creatine enhances the formation of adenosine triphosphate (ATP), the primary energy currency of cells, leading to improved performance during high-intensity, short-duration exercises. (reference)
2. Enhanced Muscle Mass & Muscle Growth: Supplementation has been shown to increase muscle mass, possibly by boosting the formation of proteins that aid in muscle fiber growth. (reference)
3. Improved Exercise & High-Intensity Performance: Creatine supplementation can enhance strength, power, and work capacity during high-intensity, repetitive exercises. (reference)
4. Neuroprotective Properties & Brain Health: Emerging research suggests creatine may support brain health by aiding in energy production and potentially offering neuroprotective benefits. (reference)
5. Support for Healthy Aging - Muscle and Bone Health: Creatine supplementation might help counteract age-related declines in skeletal muscle and bone mineral density. (reference)
Taurine, a semi-essential amino acid is naturally produced by the body and found in various foods, plays a vital role in numerous physiological processes. Taurine levels decline with age, and research suggests this decrease contributes to age-related health issues. Here are five primary benefits of taurine, supported by reputable sources:
1. Supports Cardiovascular Health - Blood Pressure and Heart Function Regulation: Taurine supplementation has been shown to reduce blood pressure in individuals with hypertension, due to improved endothelial function and reduced oxidative stress. (reference) Research has also shown that it may enhance heart muscle contractions and reduce the risk of heart failure by lowering blood pressure and calming the nervous system. (reference)
2. Promotes Nervous System Health - Nerve Growth Support: Taurine aids in the development and function of the nervous system, supporting nerve growth and potentially offering neuroprotective benefits. (reference)
3. Assists in Metabolic Regulation - Glucose Control & Lipid Metabolism: Taurine may improve insulin sensitivity, aiding in blood sugar management and reducing the risk of type 2 diabetes. (reference). Taurine also helps form bile salts in the liver, which are essential for fat digestion and overall metabolism. (reference)
4. Acts as an Antioxidant - Oxidative Stress Reduction: Taurine exhibits antioxidant properties, protecting cells from damage caused by free radicals and reducing inflammation. (reference)
5. Supports Muscular Function and Exercise Performance - Muscle Endurance: Taurine supplementation has been linked to improved muscle function, increased exercise capacity, and reduced muscle damage. (reference)
