Takeuchi Pharmaceutical Co., Ltd. (Headquarters: Nishi-Gotanda, Shinagawa-ku, Tokyo / Representative Director: Yuto Ogura), which develops D2C, OEM, and wholesale businesses for health foods and cosmetics, has begun pre-selling the new "Watermelon Flavor" of its "EAA β-ALANINE PLUS" series from THE PROTEIN (aka ZAPURO) on TikTok Shop. The general release on other platforms is scheduled for May 22.

### Development Background

THE PROTEIN (ZAPURO) brand's popular "EAA β-ALANINE PLUS" series has gained strong support from many users due to its excellent taste design, making it easy to drink even during training, and its functional benefits.

The limited-edition "Watermelon Flavor" being released this time has been highly praised among the EAA series previously offered, with numerous requests for its re-release through social media and reviews. Users frequently commented, "It's the most delicious I've ever tried," "Perfect for summer training," and "It feels like drinking juice," highlighting its high taste satisfaction.

Responding to these user voices, we decided to reintroduce the "Watermelon Flavor" within the "EAA β-ALANINE PLUS" series, not just as a simple re-release, but in a form more suitable for training scenarios. It has evolved into an "EAA that tastes good and is easy to continue," while also meeting the needs of users focused on performance.

This flavor is designed to be subtly sweet and have a refreshing aftertaste, making it easy to drink even in hot weather. We pursued a refreshing sensation that can be gulped down during exercise, achieving a crispness akin to watermelon juice.

Furthermore, this product will be pre-released on TikTok Shop from May 8, 2026. By delivering it quickly to trend-sensitive users, we aim to create real experiences and spread word-of-mouth, leading to its general release (May 22).

### EAA β-ALANINE PLUS Watermelon Flavor

#### Flavor Description

Watermelon Flavor:
An EAA flavor with a fresh and light taste reminiscent of watermelon juice.
We focused on balancing subtle sweetness and refreshing crispness, resulting in a clean aftertaste that doesn't linger in the mouth even during exercise.
Designed to minimize artificial flavors and prioritize a refreshing feel, it's also recommended for hydration during hot seasons.

#### What is EAA?

EAA stands for "Essential Amino Acid." Essential amino acids are crucial nutrients that cannot be produced by the body and must be obtained through diet. Because they can be consumed in a pre-digested state, they are chosen by those who focus on daily conditioning and nutritional supplementation during training.

- 9 Essential Amino Acids
- Valine
- Leucine
- Isoleucine
- Lysine
- Histidine
- Threonine
- Methionine
- Phenylalanine
- Tryptophan

EAA refers to the 9 essential amino acids.

#### What is β-Alanine?

Contains 3,000mg of β-alanine per serving (20g).

β-alanine is known as a component that supports condition maintenance during exercise. In the body, it combines with histidine, an essential amino acid, to form "carnosine."
Carnosine is known to support condition during exercise and aids in nutritional supplementation for those who train.

### Recommended Intake Timing

Recommended intake timing.

- For those with exercise habits, it is recommended to take it before and after training, or as hydration during exercise.
