A pilot study is being conducted to compare a new plant-based protein drink to commercially available animal-based protein drinks. The goal is to assess if the plant-based drink delivers amino acids to the bloodstream as effectively as the animal-based drinks, potentially offering a viable option for those on plant-based diets.
The study will involve approximately 12 healthy adults aged 18-40. Each participant will try all three drinks (the new plant-based drink, a commercial animal-based drink, and another animal-based recipe) on separate days in a randomized order. Before and after (30, 60, and 90 minutes) consuming each drink, a small blood sample will be drawn to measure amino acid levels (leucine).
By comparing the results, the investigators hope to determine if the plant-based drink can match the effectiveness of animal-based protein drinks in delivering essential nutrients. This research could contribute to the development of sustainable and nutritious plant-based protein alternatives.
