Interventions and Outcome Measures

Arms

experimental: Crossover group 1, randomized

Crossover study: Participants consume a test product on each of the five clinic days, at least 1 week apart, allowing for 1 week wash-out period between each product. Participants will consume each of the 4 active test products versus placebo over 5 weeks. The order of interventions for this group is A, C, B, D, E.

experimental: Crossover group 2, randomized

Crossover study: Participants consume a test product on each of the five clinic days, at least 1 week apart, allowing for 1 week wash-out period between each product. Participants will consume each of the 4 active test products versus placebo over 5 weeks. The order of interventions for this group is E, A, C, B, D.

experimental: Crossover group 3, randomized

Crossover study: Participants consume a test product on each of the five clinic days, at least 1 week apart, allowing for 1 week wash-out period between each product. Participants will consume each of the 4 active test products versus placebo over 5 weeks. The order of interventions for this group is D, E, A, C, B.

experimental: Crossover group 4, randomized

Crossover study: Participants consume a test product on each of the five clinic days, at least 1 week apart, allowing for 1 week wash-out period between each product. Participants will consume each of the 4 active test products versus placebo over 5 weeks. The order of interventions for this group is B, C, D, A, E.
