In the last few years it has been shown that Beetroot juice effects blood pressure & stamina.
In 1998 Two Swedish scientists (Weitzberg and Lundberg) found that natural nitrates (NO3) in the diet (such as those found in beetroot, spinach and lettuce) are broken down during digestion to produce nitric oxide in the blood stream.
Nitric Oxide is important because it:
- regulates blood pressure;
- controls blood flow to certain organs;
- enhances stamina by improving oxygen use;
- fights infection;
- is a signal molecule in the nervous system.
Beetroot juice is particularly high in natural dietary nitrates
Professor Amrita Ahluwalia of the William Harvey Research Institute, published a paper in March 2008 in the American Heart Association’s journal showing that oral nitrate (taken through drinking beetroot juice) reduces high blood pressure.
Professor Andrew Jones, of Exeter University, published a paper in August 2009 explaining that dietary nitrate supplementation reduces the O2 cost of low intensity exercise and enhances tolerance to high intensity exercise in humans (Journal of Applied Physiology).
Dietary nitrate has such a beneficiary impact on sporting stamina that Beet It are supplying beetroot juice for trials with UK Athletics, swimming, rowing, cycling teams and even the entire England rugby union team.
