Vitamin B3 – Niacin, or vitamin PP, influences the functioning of the brain and the peripheral nervous system; it is a deficiency problem typical of the modern world. Deficiency of this vitamin starts with skin changes – redness, spots. It ends with organ insufficiency, e.g., of the liver and pancreas.
Magnesium is an element of life that strengthens the immune system and improves digestion, memory, and thinking. It reduces the risk of heart attack, diabetes, depression, inflammatory conditions, formation of kidney stones. Regulates thyroid function and helps heal injuries.
Sodium – maintains osmotic balance (regulation of water volume in the body), acid-base balance, participates in conduction of nerve impulses, and transport of glucose and amino acids.
Potassium – one of the main electrolytes responsible for maintaining electrical tension on cell membranes and transmitting electrical impulses. Participates in protein synthesis and energy production. Supports normal blood pressure and regulates water levels in the body. Plays a vital role in the control of muscle structure.
L-Citrulline is a chemical compound and amino acid that takes part in the urea process (ammonia neutralization). It also stops the breakdown of muscle tissue and supports fat reduction. In addition, it improves strength, endurance, and aerobic capacity and reduces the feeling of fatigue. Finally, it takes care of the acid-base balance in the body.
Beta-Alanine – production of carnosine and protein building blocks. It expands blood vessels, delays the aging process, supports the proper functioning of muscles, and reduces muscle fatigue.
Taurine – an amino acid that is helpful in muscle regeneration. It infuses them with water and hydrates.
Augments sulfate – a by-product of arginine. It shows the ability to release growth hormones and produce nitric oxide.
N-acetyl L-tyrosine – a derivative of the less soluble L-tyrosine. It ensures fast and practical thinking, improves long-term memory, increases mental and physical performance, reducing the feeling of fatigue.
Creatinol-O-Phosphate (COPMax) – an ingredient similar to Beta-Alanine. Creates a lactic acid buffer, which increases training intensity.
Caffeine Anhydrous – caffeine in a dehydrated form, which facilitates its precise dosage. Not only does it allow you to keep your mind sober even when you’re feeling the most fatigued, but it also has a positive effect on maintaining average body weight.
L-norvaline – a non-branched amino acid. Supports the development of muscle tissue and improves body regeneration.
Rhodiola Rosea (Rhodiola Rosea) – a plant that supports the body in adapting to heavy strain – both physical and mental. It reduces fatigue, improves concentration and mood.
Creatine mix – magnesium creatine chelate, creatine monohydrate – ensures faster regeneration, better muscle appearance, and recovery.
