Iron is the most abundant mineral in the blood. In addition to having a role in the process of cell division, iron contributes to the normal formation of red blood cells and haemoglobin, to the reduction of tiredness and fatigue and normal energy yielding metabolism. Iron also supports normal oxygen transport in the body, normal cognitive function, and normal function of the immune system. B Vitamins are especially important for energy, converting consumed food into usable sources of energy through something often referred to as our ‘energy yielding metabolism’. Effervescent supplements are supplements which come in a tablet form. They are a good option for people who don’t like swallowing tablets but still want to get their vitamins.
