According to a research study done by Exeter University scientists beetroot juice boosts energy levels and gives new energy for  old and weak people. It works extremely well for Athletes.

Beetroot juice contains plenty of Nitrite, which ultimately shows its effect by dilating blood vessels due to this reason intake of oxygen increases when beetroot juice consumed.

Beetroot helps to lower blood pressure and  eliminates weakness in older age.  Beetroot juice is been experimentally tested on a set of cycling champions by giving nitrite separated beetroot juice at one time and without separating nitrite at  another time. Results showed up amazingly upon their performance  when they consumed one pint of beetroot juice without separating nitrite.

As per above results beetroot juice is a very good healthy and energy drink.
