Daphnia, otherwise known as water fleas, have a circulatory system similar to mammals. Most importantly, they have a With a stopwatch and attention to detail, you can test whether a particular chemical has any effect on heart rate.

Their hearts are found on their dorsal side ( their ‘backs’), above the brood pouch where you may find young if the Daphnia is a female

A supplement with more carbohydrates will increase the heart rate the most. A pre-workout caffeinesupplement will cause a large behavior change. (More movement)

How do sport supplements affect the heart rate and behavior of Daphnia Magna (Water Flea)

I would like to know what the specific supplements you are going to test are? Accurate design and execution of your experiment will be very crucial to the credibility of your results. You will need to think carefully about controlling your variables to keep everything constant other than the variable you are testing (supplement type). Also, make sure you have a good sample size of Daphnia so your results will be evident in more than just one Daphnia to eliminate the chance of your findings just being related to the individual Daphnia you used.
