Love it or hate it, Marmite could benefit your training…

Why? Because Marmite contains B12, B12 like all vitamins is a facilitator – in its specific case it aids the formation of DNA, is required for the synthesis of brain neurotransmitters and important amino acids and the general growth and division of cells, including those in bone marrow, which go onto form blood cells.

Red blood cells are crucial for carrying oxygen around our body and a lack of B12 can result in a reduced red blood cell count and fatigue both physical and mental, which will affect training.

How much B12 do you need?

The UK RNI for B12 is 1.5mcgs a day.
