NIH Recommendations and Oxygen Uptake Supplements for Adolescents
The National Institutes of Health (NIH) does not specifically recommend any supplements for improving oxygen uptake during cardio exercise in adolescents. However, several supplements have been studied for their potential to enhance oxygen uptake (VO2max) and aerobic capacity in young, healthy individuals.
Protein Supplementation and VO2max in Young People
Research shows that protein supplementation during endurance training can lead to greater increases in maximal oxygen uptake (VO2max) and lean body mass compared to carbohydrate supplementation in young, recreationally active males. However, this improvement in VO2max did not translate to better muscle oxidative capacity or endurance performance over a 10-week period of training. While these results are promising, they are not specific to adolescents and are not part of official NIH guidelines.
Hydrogen-Rich Water and Aerobic Capacity
Continuous supplementation with hydrogen-rich water for two weeks has been shown to significantly increase peak oxygen uptake during incremental cycling exercise in healthy humans. This suggests that hydrogen supplementation may help improve aerobic exercise performance, but the evidence is limited and not specific to adolescents or NIH recommendations.
Inorganic Nitrate (Beetroot Juice) and Muscle Oxygenation
Short-term supplementation with inorganic nitrate, commonly found in beetroot juice, has been found to improve muscle oxygenation, speed up oxygen uptake kinetics, and increase exercise tolerance during high-intensity cycling in young adults. These effects were more pronounced at higher exercise intensities, indicating that nitrate supplementation may be particularly effective for improving oxygen delivery and utilization during intense cardio exercise.
Nicotinamide Mononucleotide (NMN) and Aerobic Capacity
Supplementation with nicotinamide mononucleotide (NMN), a precursor to NAD+, combined with exercise training, has been shown to increase aerobic capacity and oxygen utilization in healthy amateur runners. The improvements were dose-dependent, with higher doses leading to greater increases in oxygen uptake and exercise performance. However, this supplement is not currently recommended by the NIH for adolescents.
Omega-3 Fatty Acids and Endothelial Function
Omega-3 fatty acids supplementation for three weeks has been shown to improve endothelial function and increase maximal oxygen uptake in endurance-trained athletes. The improvement in oxygen uptake was associated with increased nitric oxide production, which plays a key role in cardiovascular health and exercise performance. Again, these findings are not specific to adolescents and are not part of NIH guidelines.
Conclusion
While several supplements—including protein, hydrogen-rich water, inorganic nitrate (beetroot juice), nicotinamide mononucleotide (NMN), and omega-3 fatty acids—have shown potential to improve oxygen uptake and aerobic capacity in young, healthy individuals, none are specifically recommended by the NIH for improving oxygen uptake during cardio exercise in adolescents. Most evidence comes from studies in young adults or athletes, and more research is needed to determine safety and effectiveness in adolescents. For now, the best approach for adolescents remains regular exercise and a balanced diet.
