Comparing a new plant-based protein drink to animal-based options
Exploratory Pilot Trial Assessing the Immediate Impact of Animal-based and Plant-based Protein Drinks on Blood Parameters
This study is testing a new plant-based protein drink to see if it provides the same essential nutrients as animal-based protein drinks for healthy adults.

What this trial studies
This pilot study aims to evaluate the bioavailability of a new plant-based protein drink in comparison to commercially available animal-based protein drinks. Approximately 12 healthy adults aged 18-40 will participate, consuming each drink on separate days in a randomized order. Blood samples will be collected before and after consumption to measure amino acid levels, specifically leucine, at various intervals. The goal is to determine if the plant-based drink can effectively deliver essential nutrients similar to its animal-based counterparts.
Who should consider this trial
Good fit: Ideal candidates for this study are healthy adults aged 18-40 who do not have a history of smoking or cardiovascular diseases.
Not a fit: Patients with a BMI over 35, allergies to soy, peas, milk, lactose, or fructose, or those who engage in high-intensity exercise shortly before participation may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide a nutritious and sustainable protein option for individuals following plant-based diets.
How similar studies have performed: While this approach is relatively novel, previous studies have explored protein bioavailability, but direct comparisons between plant-based and animal-based drinks are limited.
