Recent research indicates that beetroot juice supplementation can enhance physical performance, particularly through its high concentration of nitrates. These nitrates are converted in the body into nitric oxide (NO), a molecule known to improve blood flow, increase oxygen efficiency, and delay fatigue. While a growing body of evidence supports this ergogenic effect, the optimal dosage and its impact on different types of exercise and fitness levels remain a key area of study.

The absorption of vitamin C in the human body is a surprisingly complex process, regulated by saturable transport mechanisms. These limitations mean that simply taking a higher dose of supplements doesn't guarantee your body will absorb more, directly addressing the question of what limits vitamin C absorption. This article explores the various factors involved in this process, both internal and external, to help you maximize your intake.
