MYPROTEIN – Protein and Health Supplements
MYPOTEIN started out as a protein supplement brand. Their product range has grown substantially over the years. Now, they carry many popular supplements for sports and performance enhancement. In addition, they have a range of vitamins, minerals, energy drinks, protein snacks bars, and full nutrition meal replacement shakes.
One reason for the growing popular appeal of MYPROTEIN in Japan is their focused categories for vegan and vegetarian protein solutions and other such supplements.
Their vitamin, mineral, and health products now come under the brand name MyVitamins. Similarly, all vegan based products and protein powders are found under the name MyVegan. They now also have a small organic product line.


How to Buy MYPOTEIN Products in Japan
You can buy MYPROTEIN, MyVitamin, or MyVegan protein powder and supplements through their official Japan website. However, this website is only available in the Japanese language.
We confirmed directly with a MYPROTEIN agent that residents of Japan need to use the Japanese website. Therefore, it is not advisable to buy products on their UK English website if you are living in Japan.
For some, this may sound like a daunting proposition, but actually it’s not. You can easily sign-up and log-in via a Google or Facebook account. Furthermore, you can enter you name and address in English on their website even though the instructions are in Japanese. For polite convenience, you can easily just copy and paste your address in Japanese from a Google or other map search.
How To Navigate the Japanese MYPOTEIN Website
The easiest way to navigate the My Protein Japan website is to brush up on your katakana. Either that, or install a translation browser plug-in such as Rikaichan. Alternatively, just navigate between the two websites.
The caveat really is that all the same products are available on the UK site anyway. It’s easier to search the UK website for products – especially for nutritional and ingredient information. You can then just search for the same product on the Japanese language site using the English name. Products distributed in Japan all have English language packaging. Therefore, it’s easy enough to pick out what you’re looking for.
The general layout of the Japanese website is identical to the English site. By clicking the left navigation tab on either site, you will get a drop down of the Nutrition site map:

This is how it compares to the Japanese language site map for protein. It’s very much the same except for a few minor category differences detailed further below:

Under the principle Protein Powder tab [ プロテイン ] there is no listing for Clear Protein on the Japan page. The Clear Protein range is available, however, on the Japan website.
This product is a recent innovation that takes high quality isolate proteins and infuses them with fruit extracts. This creates a light and fruity like protein drink as opposed to a milky shake. Clear Protein won the ‘The Best Sports Nutrition Product’ in the European Specialist Sports Nutrition Awards 2019.
The Japanese listings under Vitamins & Minerals [ ビタミン&ミネラル ] likewise doesn’t have separate categories for Immune Health and Omega 3 & Fish Oils. Many of the same products are available nonetheless. The Japanese website has a separate category for MBH Amino Acids.
The Japanese website has an extra category next to Carbohydrates [ 炭水化物 ] called [ 食物繊維&必須脂肪酸サプリメント ] or Dietary Fiber & Essential Fatty Acid Supplements. Here you will find omegas, green superfoods including Spirulina, Macca, different types of extracted fiber, and more.
A nice difference is how the Japanese site makes lifestyle or dietary foods categories [ 食スタイル別 ] more accessible. These include sub listings for lactose intolerance [ 乳糖不便用 ], vegetarian [ ベジタリアン ], vegan [ ビーガン ], organic supplements [ オーガニックサプリメント ], and gluten free [ グルテンフリ ].

Other Places to Buy My Protein Products in Japan
MYPROTEIN [ マイプロテイン ] products are not so plentiful on amazon.jp – except for their highly popular Impact Whey Protein and a few others.
You’ll find a lot more of MYPROTEIN on Rakuten, especially if you’re looking for their plant or vegan protein powders. Another popular place is Mercari Shopping and also Yahoo Shopping.
You won’t find MyProtein in typical Japanese drug stores or places like Donkihote, Biccamera, or Yodobashi. You may find the core of their protein powder range in more local or specialist sports supplement shops, nutrition depots, or maybe local gyms.
For picking up a fast cheap deal, you can compare the going prices on popular online retailers. However, as adequately explained in this Japanese blog, the periodic member discounts and campaigns on the official site turn out cheaper in the long run.
Also, it may be that some of the products on third party commercial retail sites could be resold products. Either that, or products have closer expiry dates, or the quality cannot be 100% guaranteed. The drawback is that ordering direct takes more time with shipping. This is especially so during pandemic periods. The best solution is order your supplements in advance when deals come through – and not when your last packet has run out.
Questions and Answers about MYPROTEIN in Japan
Here are some questions you may have about the MYPROTEIN brand, especially with regards to their quality, use of synthetic ingredients, as well as for specific dietary needs:
Do MYPROTEIN Products Use Artificial Sweeteners?
Generally speaking, most MYPROTEIN whey and plant protein supplements contain sucralose. If you want to avoid this artificial sweetener your options are the unflavored protein. Alternatively, there’s the more recent range of stevia [ステビアー] flavored protein powders.
Many of the MyVegan product range do not use artificial sweeteners. Instead, some use distilled alcohol sugars such as Xylitol, Maltitol, Erythritol, and/or Stevia. It’s best to look at the separate MyVegan homepage for a more details and then search the Japanese site for products that suit you.
The following products are examples of artificial sweetener free choices:
- Vegan Protein Shake
- Whole Fuel Blend
- Vegan Protein Recovery Blend (all flavors)
- Vegan Protein & Greens (all flavors)
- Hemp Protein Powder
- Brown Rice Protein
- Vegan Protein Baked Cookies
- Gooey and (some) Baked Cookies
- Peanut squares (vegan)
- Lean Flap Jack (not vegan)
- Protein Spread / Protein Dip Pot (not vegan)

What’s the Deal with Vegan and Plant Protein Powders?
In terms of plant protein powders or soy protein powders easily available in Japan, MyVegan is a welcomed additional choice. Although most of the flavored varieties contain sucralose, the unflavored Pea Protein Isolate is an excellent product.
Hemp protein powder is relatively easy to get hold of in Japan. However, the above mentioned MyVegan Brown Rice Protein, Vegan Protein & Greens, Vegan Protein Recovery Blend, and Whole Food Blend are top recommendations for the more health conscious. These products have few quality equivalents in Japan.
