[Development Background]
A long-awaited new flavor has been added to the popular 'THE PROTEIN EAA β-ALANINE PLUS' series.
The development theme was 'ease of drinking that is easy to continue every day, even in the hot season.'
We aimed for a product that can be enjoyed like juice, not only during training but also on days without exercise, by focusing on a refreshing aftertaste with reduced sweetness. We pursued a refreshing drinking experience that doesn't feel heavy, even during exercise, allowing users to drink it easily.
In selecting the flavor, we conducted multiple user surveys on social media. 'Shine Muscat flavor,' which received the most support among many candidates, was commercialized.
This new flavor was developed with the goal of being 'delicious and easy to continue' for a wide range of users, from those who train daily to light users.
[Realities of EAA Users Revealed by SNS Survey]
We conducted a survey on the consumption status of EAA on the official Za-Pro X account.
In response to the question 'Do you drink EAA?', approximately 61% of the 136 respondents answered 'Yes.' Furthermore, regarding the purpose of consumption, approximately 76% of the 38 respondents answered 'I am conscious of improving performance during muscle training and exercise.' This reveals that EAA is being incorporated as part of conditioning during exercise, primarily by users with training habits.
This product was developed with a flavor profile designed to be easy to drink and maintain even during exercise. The survey results reveal that a large portion of users incorporate EAA into their daily lives or use it for nutritional support during exercise, indicating a growing need for amino acid supplementation in training scenarios.
