Supplementing with Beetroot Juice
SHOUT-OUT to BeetIt
who supply beetroot juice for endurance sports. Their daily shot has c400mg nitrate.
Personally using BEET juice I’ve found my cardiovascular system feels CLEANER as though the blood is getting to the muscles with oxygen FASTER.
Nitrates dilate blood vessels. Fats need oxygen to metabolise into energy. Energy availability is limited by how fast you can supply the oxygen to the muscles.
Drinking BEET juice on the MORNING of a run has worked BEST for me.
