The strongest protein drink in the history of Oikos is born! Contains 25g of highly absorbable protein

OIKOS, which supports high-quality protein supplementation for all physically active people, has introduced a new protein drink containing 25 grams of highly absorbable protein. The first product is the ” Rich Vanilla Flavor.

More advanced post-workout nutrition!Contains 25g of highly absorbable protein! Oikos' strongest protein drink ever!

Oikos launched “Oikos Protein Drink” in 2024 to provide an easy way to replenish high-quality protein in various everyday situations. Since then, the company has responded to the protein supplement needs of people who are physically active on a daily basis by offering a variety of flavors of protein drinks containing 18 g of “high-absorption protein,” which is highly absorbable by the body and easily used for muscle synthesis. On the other hand, many trainers who engage in high-intensity exercise, such as strength training, demanded a higher level of nutritional supplementation, such as 20g or more of protein after exercise.

The new “Oikos PRO Protein Drink High Absorption Protein 25g” series was created in response to this background. To meet the needs of those who engage in higher-intensity training, this product has the same volume (240 ml) as the previous series and contains 25 g of highly absorbable protein, the most in Oikos’ history. It also contains nine essential amino ^acids*1 that are important for post-workout recovery and bodybuilding, and the nutritional value has been enhanced by newly adding vitamins B1, B6, and D, which are closely related to training. The new product also retains the features of the previous series, ” zero fat” and “no sugar.

The first product in the series, ” Rich Vanilla Flavor, ” as the name suggests, has a vanilla flavor reminiscent of mellow custard. As the protein content increases, the viscosity of the drink itself increases, which can make it difficult to drink. Oikos has devised a recipe to suppress this high viscosity, creating a light, refreshing drink. In order to soften the unique aroma that increases as the protein content increases, Oikos has carefully adjusted the balance of sweetness and flavor by carefully selecting vanilla flavors that go well with protein drinks, resulting in a refreshing aftertaste. In addition, to make the high-protein beverage more comfortable to drink, a new straw thicker than the previous 18g series has been adopted.

We asked Mr. Bazooka Okada!What is the importance of daily protein intake and physical activity?

For the launch of this new product, Danone Japan invited Bazooka Okada, a professor at the Japan University of Physical Education and a bodybuilder, to attend the presentation. Mr. Okada gave a lecture on the importance of daily protein intake and physical activity. OTOKOMAE editorial staff members who attended the presentation also interviewed Mr. Okada. Mr. Okada also said that he incorporates Oikos into his daily life.

Bazooka Okada-san

When I first encountered Oikos yogurt, I was shocked. I was doing bodybuilding and was looking for food at a convenience store when I said, ” What the heck is this?” And I was like, “What is this? I immediately adopted it into my life, and all the muscle training enthusiasts around me were also using it. There are times when I have to lose weight for bodybuilding, but it is mentally difficult to enjoy meals less. Oikos tastes great, so not only does it provide protein, but it also satisfies my taste buds. I also used to use “Oikos as a snack” when I was hungry.

─ For whom would you recommend the drink type, and in what situations?

Bazooka Okada-san

We are of course incorporating the drink as well. Now that 25g is on the market, it is even easier to use; 25g in 240ml is the strongest concentration. I’m glad that I can take it very efficiently, because if I guzzle it to get the right amount, I get full. I would especially recommend it to men with large bodies who need a lot of protein. On the other hand, for women who are not that big, I recommend the conventional 18g. Even for those who don’t do muscle training, if you feel that you don’t have enough protein in your diet, this drink is a good way to reinforce it. For example, if it were me, I would use something like two rice balls and a bottle of this when I don’t have time for lunch.

─ ─ What is the most efficient “health investment” you recommend, Okada-san?

Bazooka Okada-san

If we are talking about efficiency, I would say protein. I would say, “Do muscle training! I would like to say, “Do muscle training,” but some people don’t like to do muscle training, so I would recommend eating meals or consuming high protein foods like these Oikos. Even for those who don’t do muscle training, just being conscious of moving your body in a reasonable way, such as taking the stairs instead of the elevator or escalator, and consuming protein will make a difference in terms of lifestyle.

─ ─ What does “manly” mean to you, Mr. Okada?

Bazooka Okada-san

To me, manliness is ” alpha male “. An alpha male is the leader of a pack, such as a lion or a monkey, for example, but being strong is not enough. They have to have kindness, compassion, and dignity. Like such an alpha male, a person who has all the elements of ” strong, gentle, and beautiful” is a true manly man. Beautiful is aesthetics. To become such a man is muscle training! That’s what I think.

Protein effect equivalent to chicken meat!Oikos boasts highly absorbable protein

Protein is essential for building muscles and bones, and it is important not only in quantity but also in quality. Oikos’ definition of “highly absorbable protein” refers to high-quality protein that is absorbed and utilized by the body at a high rate and is easily utilized for muscle synthesis and other purposes. The protein in Oikos is absorbed and utilized by the body at a rate comparable to that of boiled chicken ^meat*2, and has been shown to be absorbed into the bloodstream at a high rate.
