I have been seeing ads on TV recently for a product called Superbeets that is said to increase blood flow by relaxing blood vessels, thus increasing stamina by improving the oxygen supply to muscles and nerves. It is also said to lower blood pressure. Sounded interesting but, it is not cheap, so I researched it. This is due to the presence of nitrates that promote the production of nitric oxide.
One great thing about the internet, and I have a lot of complaints in other areas, is how easy it makes simple research. Extensive research is another issue, but, for things like product backgrounds, it's great.
Well, it seems that increasing nitric oxide levels is beneficial, to a degree and that beets do contain the appropriate nitrates. However, so do leafy green vegetable and, for reasons unexplained, simple walking also increases nitric oxide levels. Beet juice does seem to work especially well, and is most efficient when combined with walking and green leafy vegetable consumption.
So, given that the supplement is costly, and there seems to be no indication that it works better than the juices and raw vegetables, the sensible thing to do, and a far less expensive thing to do, is just use the raw products. You can buy juices, of decent quality in health store (and now, often, in grocery stores) or, just buy the vegetables and a juicer and make your own. And, of course walking is free. See, a little, simple research can save you money.
