For years fitness insiders — including distance runners, bodybuilders, and even Olympic athletes — have used natural beet juice to boost endurance and athletic performance. Now we have some real scientific evidence proving the effectiveness of one of its main components: the vitamin betaine.
Researchers at Ithaca College added 2.5 grams of betaine to a 20 oz sports drink and had a group of young cyclists drink half in the morning and the other half later in the afternoon for several days. They found it boosted sports performance significantly. Both average and maximum peak power increased. Just one week of taking the betaine supplement led to an increase in peak and mean anaerobic power of 5 and a half percent!
According to study supervisor Thomas Swensen:
“Betaine may contribute to creatine synthesis, which improves, strength, power and short-term performance… Future research should elucidate the mechanism of how betaine supplementation improves performance.”
The Bottom Line: If you want to improve your own athletic performance — without breaking any laws — you might want to consider drinking some beetroot juice or taking a betaine supplement! (Oh, and it also helps lower blood pressure.)
