Complex carbohydrate powder
PhD Waxy-Vol contains pure barley powder and is derived from finest UK crop. Barley is recognised as a complex carbohydrate.
Complex carbohydrates is a term used to describe foods that are high in starch (cereal’s, breads, grains), whilst the term simple sugars is used to describe foods that are traditionally high in monosaccharides and disaccharides, which are smaller (lower molecular weight) and are found in sweets, fruits, fruit juices etc.
Traditionally, athletes will require the majority of their carbohydrate intake from complex carbohydrates (starches), except perhaps for a period of 1 hour after exercise when it may be preferential to use simple sugars, as they may be converted into glycogen quicker than starches.
