Sodium Bicarbonate (Baking Soda) : The Second Line Of Defence On Fatigue

OK, so you might have read my last post on Carnosine and its role in fighting fatigue, Carnosine defends from inside the muscle, whilst our unsung hero Baking Soda works outside of the muscle…in the blood stream. Acidosis is a term describing the elevated acidity of the blood through the increase in hydrogen ions, a bi-product of energy metabolism. An established (but lesser known) way of reducing the acidity of the blood is to start exercise in a relative alkaline state i.e. higher than normal blood pH…known as induced alkalosis. You can achieve this by ingesting approx 0.18-0.3g/kg body weight of Sodium Bicarbonate around 30mins prior to exercise.

NOTE: Exercise caution when trying to manipulate the pH of your body, an over alkaline state can be as equally damaging as an acidic internal environment. Also be aware that sodium bicarbonate can cause gastrointestinal upsets in some people, leading to upset stomachs, diarrhoea, nausea and vomiting. It may not be for everyone therefore exercise caution and start the dose low.
