Endurance Supplements

Endurance supplements are used by endurance athletes to enhance endurance exercise performance and to cope with the demands of heavy training loads.

Supplements For Endurance Athletes

Acetyl L Carnitine

Acetyl L Carnitine is believed to improve muscular endurance, mental function, alertness, memory, and to reduce the age associated decline in brain function

American Ginseng

American ginseng is believed to enhance fatigue resistance, boost immune function, protect against muscle damage, and improving mental & physical stamina.


Beta-Alanine is a naturally occurring amino acid. Beta-Alanine supplementation is elevates muscle Carnosine levels which help to buffer against the build up of lactic acid, and has been shown to enhance endurance exercise performance.

Branched Chain Amino Acids (BCAAs)

BCAAs stimlate muscle building (anabolism) whilst decreasing muscle breakdown (catabolism). Increases lean muscle mass, reduces muscle damage and soreness, improves immune function, and may enhance endurance exercise performance.


Bicarbonate is often used by endurance athletes to enhance athletic ability by buffering the build-up of lactic acid in the blood.


Caffeine has long been considered an ergogenic aid that is capable of improving physical performance. It works by activating the central nervous system and sympathetic nervous system.


Carnosine may enhance exercise performance by reducing the build up of hydrogen ions (lactate) within muscle cells.

Chondroitin Sulfate

Chondroitin helps to reduce the cause of pain associated with injury, speed the injury recovery rate and may reduce the risk of injury.

Citrulline Malate

Citrulline Malate has many positive effects on aerobic exercise performance including: 1) increased aerobic production of energy; 2) Improved stamina and fatigue resistance, and; 3) improved recovery and energy levels.


Colostrum can help to increase lean muscle mass and enhance endurance performance.

Co-Enzyme Q10

Co-Q10 is a powerful antioxidant that may enhance endurance exercise performance. It is present in particularly high levels in the heart where it is believed to enhance the function of the heart.

Cordyceps Sinenis

Cordyceps is believed to improved fatigue and stress resistance, improved immune function, lower cholesterol levels, may possess anti-tumour properties, and appears to have anti-ageing & anti-oxidant properties.

Essential Fatty Acids (EFA’s)

EFA’s may help to enhance fat free mass.

Glucosamine Sulfate

Glucosamine is an important building block, found in high concentrations in joints. Glucosamine is needed for the manufacture of cartilage and also plays a role in the formation of collagen. Glucosamine is usually sold as either glucosamine sulfate or glucosamine hydrochloride (HCL).


Glutamine is the most abundant amino acid in the human body making up over 50% of the total amount of amino acids. Glutamine is essential for growth and normal immune function. It can help to increase lean muscle mass and recovery from exercise.

Hydroxy Methyl Butyrate (HMB)

HMB (Beta-hydroxy-beta-methylbutyrate) appears to have anti-catabolic properties. It appears to enhance muscle mass and muscular strength.

Sodium Phosphate

Sodium Phosphate is believed to enhance muscular endurance and aerobic capacity. Phosphates are believed to buffer the build up of hydrogen ions.


Pycnogenol enhances nitric oxide production which ould enhance muscle mass. It may also enhance growth hormone secretion and aid recovery from exercise.

Rhodiola Rosea

Rhodiola rosea (Golden root) is an adaptogen, that may enhance the body’s ability to cope with external stresses. It is believed to stimulate the nervous system, enhance work performance, and reduce fatigue.

Siberian Ginseng

Siberian Ginseng is believed to have adaptogenic properties, in that it enhances are body’s ability to cope with external stresses (physical and mental). It has been widely studied in Russia, where it has been used extensively as an adaptogen to increase resistance to stress, fatigue, & disease.

Whey Protein

Both casein and whey protein have traditionally been used by body builders, and strength athletes to increase the rate of protein synthesis (muscle building), whilst decreasing the rate of catabolism of muscle mass (muscle breakdown), and increasing the rate of post exercise recovery.


ZMA can increase the levels of total testosterone, free testosterone, recovery and muscular endurance.
