Letter referenced:

Lundberg JO, Larsen FJ, & Weitzberg, “Supplementation with nitrate and nitrite salts in exercise: a word of caution”J. Appl. Physiol. 111:616-617.

Summary of Allen’s letter:

             The author acknowledged that there are some risks with consuming nitrates and nitrites but, in general, the probability of risk is low and these compounds can increase the efficiency of circulation, being particularly beneficial for those with circulation problems.  He does not advise against supplementation, like Lundberg et al., but recommends it for improved circulation under a physician’s supervision.


The author did not discuss whether the benefits of nitrate/nitrite supplementation outweigh the risks for healthy individuals with normal circulation who would like to supplement for the purpose of gaining endurance in sports events.
