Though some may experience unpleasant side effects, all of the following supplements have some demonstrated research findings that they may perform to some extent as claimed except ________. Question 35 options: a) sodium bicarbonate b) dietary nitrate c) carnitine d) creatine e) beta-alanine

The question is asking which of the listed supplements does not have research findings supporting the claim that it performs as expected. The options are:

a) Sodium bicarbonate b) Dietary nitrate c) Carnitine d) Creatine e) Beta-alanine

To answer this question, we need to look at the research findings for each supplement:

a) Sodium bicarbonate: Research has shown that sodium bicarbonate can improve performance in short, high-intensity exercises.

b) Dietary nitrate: Studies have found that dietary nitrate can enhance exercise performance.

c) Carnitine: The evidence on carnitine is mixed. Some studies suggest it might improve exercise performance, but others have found no effect.

d) Creatine: There is strong evidence that creatine can increase muscle strength and size.

e) Beta-alanine: Research has shown that beta-alanine can improve performance in high-intensity exercises.

Based on this information, the supplement that does not have clear research findings supporting its performance claims is carnitine (option c).
