Glucose
Glucose, also known as dextrose, is a carbohydrate which provides energy for both metabolism and physical activity. The process of digestion commonly breaks the foods we eat down into...
Glucose Tolerance
This refers to the ability of muscle cells and the liver to remove glucose from the bloodstream. Glucose tolerance decreases with age. This factor can contribute to what is now commonly...

Glutamine is a conditionally essential amino acid, meaning that at times of intense stress placed on the muscle tissue, it becomes essential. Glutamine in supplement form is known as...
Glutathione
Glutathione (an abbreviated description for Glutathione Peroxidase), is one of the body's primary anti-oxidants. It protects the body from molecular damage caused by free radicals,...
Gluten
Gluten is a protein found in grains including wheat, rye, oats and barley. People with coeliac disease are sensitive to gluten. In this condition the lining of the small bowel is damaged by...
Glycemic Index
Glycemic Index (GI) is a rating system indicating the different speed with which carbohydrates are processed into glucose by the body. In general, complex carbohydrates are broken down...
Glycine
Glycine is an amino acid found in most proteins that inhibits the transmission of nerve impulses in cells. As a component of Creatine – the amino acid important for muscle power energy,...
Glycoaminoglycans
Glycosaminoglycans (GAGs) are present on the surfaces of all adherent animal cells and in extracellular matrices. GAGs interact with many families of growth factors and growth factor...
Glycogen
Glycogen is the stored form of carbohydrate (specifically glucose) existing mainly in the muscles and liver. Humans form glycogen as a means of storing excess glucose. Glycogen is broken...
GMOs
Genetically Modified Organisms.
Gout
What is it? Gout is a common form of arthritis that is associated with raised blood levels of uric acid. This occurs due to aggregated deposits of urate crystals in and around the joints...
GreenTea
Green Tea is the unprocessed, dried young leaves of Camellia sinensis. The main active constituent in green tea is polyphenol. Polyphenols are absorbed rapidly and have demonstrated potent...
Gut dysbiosis
Dysbiosis is an imbalance in the microbiology of the small and/or large intestine and the most common cause of Impaired Bowel Function (IBF). There are normally over 70 trillion bacteria...
HCA
See Hydroxy-citric acid
Herbicides
Chemicals and chemical compounds used to kill weeds. Organic farming prohibits their use.
Hives
Also known as urticaria, hives is a skin rash usually occurring as an allergic reaction that is marked by itching, and small pale or red swellings. It can last several hours up to several...
HMB
HMB, or beta-hydroxy beta-methylbutyrate, is a compound made in the body and a metabolite of the essential amino acid leucine. Research has found that HMB decreases post-exertion muscle...
Homocysteine
Homocysteine (Hcy) is an endogenous (made within the body) amino acid that increases with age or as a result of an inborn error of metabolism, known as homocystinuria. Elevated total plasma...
HPLC Tested
HPLC tested, or High Performance Liquid Chromatography, a scientific method used to determine the purity of amino acids.
Humectants
Used in icings, cakes, soft tortillas, dried fruit and muesli bars, humectants help maintain moistness and prevent the drying out of certain foods. They include polydextrose (1200),...
Hydroxy-citric acid
Hydroxy-citric acid (HCA) is a substance unique to the fruit of the Garcinia tree (Brindleberry) that inhibits the synthesis of fats. When carbohydrates are eaten they are broken down into...
Hypertension
Hypertension is a progressive increase in the muscle and elastic tissue of the arterial walls resulting from elevated blood pressure. This is generally defined when blood pressure is...
Hypoallergenic
Hypoallergenic is not actually a medical term but is commonly used to describe food, products or other items that cause fewer allergic reactions.
Hypoxia
Hypoxia is a pathological condition in which the body (or a region of the body such as the tissues) is deprived of adequate oxygen.
IGF-1 and IGF-2
IGF-1 and IGF-2, widely regarded as the most significant contributors to muscle growth, are insulin-like growth factors critical for the recovery and strength of muscle tissue damaged as a...
Immunoglobulins
Immunoglobulins are a class of proteins that function as antibodies, vital for protection against infection and disease. They are divided into five classes: IgA, IgD, IgE, IgG, IgM) on the...
Impact carbs
Manufacturers recently began using the statements "Impact Carbs" or "Net Carbs" on products. While not formally recognised, these terms are provided to assist weight-conscious and...
Inflammatory Bowel Disease (IBD)
IBD is a name given to a group of chronic digestive diseases of the small and large intestines. Most often it is divided into two groups: Ulcerative Colitis and Crohn's disease. Many...
Inosine
This amino acid is important for the formation of Adenosine. Adenosine is the final energy source required for muscle cell contraction and it may be useful with Creatine loading. Inosine...
Inositol
Useful for reducing blood cholesterol, Inositol removes fat build up in the liver and intestinal lining. This also makes it a mild laxative (by stimulating intestinal muscle action)....
Insulin
Insulin is a hormone produced by the pancreas. Insulin is essential for the metabolism of carbohydrates, helping to regulate the amount of glucose in the blood and increasing the ability of...
Insulin Resistance
Insulin resistance occurs when the body doesn’t respond as well to the insulin that the pancreas is making and glucose is less able to enter the cells. Insulin resistance may increase risk...
Ionisation
Ionisation is a process in which an atom or molecule loses or gains electrons. This can involve acquiring an electric charge or changing an existing charge.
Iron
Iron combines with protein and copper to make hemoglobin, which carries oxygen through the bloodstream from the lungs to all bodily tissue. Iron also helps form myoglobin, an oxygen...
