Could the key to better endurance be BEET JUICE!??!

Only up to a point.

Recommended dosage:

Eight ounces (two juiced beets) three times a week. Blend with eight ounces of sweeter fruit juices, like apple, carrot, or tangerine, to improve the taste.

Isn't antioxidant just a fancy word for vitamin?

there are other things to juice which give you the same or more/better nutrition and which do NOT stain my damn juicer pink! /wishing-i-knew-then-what-i-know-now-lol
