The earliest readily identifiable trademark record for Didacat dates to December 31, 2020, when an application was filed in the United States under serial number 90443384. The mark was subsequently registered on August 10, 2021, as U.S. trademark registration 6448917. The record lists Shenzhen Shuihaochuan Trading Co., Ltd. as the owner and indicates commercial use beginning in December 2020.[1]

The original U.S. trademark specification was broad, covering products falling under pharmaceutical and nutritional preparations. Listed goods included dietary fiber, glucose and protein supplements, cod liver oil, medicinal alcohol, medicated hair lotions, nutritional supplements, and pet diapers.[2]

The brand subsequently expanded its trademark footprint internationally. In the United Kingdom, Didacat was filed in 2025 and registered for Class 5 products including nutritional supplements, vitamins, probiotics, protein supplements, and veterinary supplements. A European Union trademark record likewise shows Didacat registered in Class 5, with goods covering nutritional and vitamin supplements, multivitamins, probiotics, protein supplements, prenatal vitamins, and supplements for both humans and animals.[3]

Didacat’s publicly visible product range centres on supplementation and general wellness rather than conventional prescription medicines. Categories associated with the brand include:

• Vitamins and minerals
• Multivitamins
• Vitamin B-complex products
• Protein and nutritional supplements
• Probiotic supplements
• NAC (N-acetylcysteine) supplements
• Magnesium supplements
• Collagen products
• Krill oil
• Kidney and urinary-health supplements
• Liver and antioxidant-oriented supplements
• Supplements marketed for veterinary or pet use

The UK trademark specification explicitly covers liquid nutritional supplements, vitamin supplements, mineral supplements, multivitamins, probiotics, protein supplements, vitamin drinks, prenatal vitamins, and vitamin/mineral supplements for pets and animals.

In the Philippines, online listings show Didacat-branded products such as NAC supplements, Vitamin B Complex, and Kidney Cleanse formulations being sold via e-commerce platforms.[2] An independent supplement database currently lists seven Didacat products, including Antarctic Krill Oil, Magnesium Glycinate, and Multi Collagen Peptides, though it notes insufficient information to assign the brand a TrustScore.[4]

Based on its trademark portfolio and publicly listed products, Didacat is characterised as an e-commerce-oriented nutritional supplement brand. Its product positioning revolves around accessible, single-purpose supplements rather than a narrow range of premium specialised formulations. Marketing areas include:

• General nutrition
• Vitamins and minerals
• Digestive and gut health
• Immune support
• Liver and antioxidant support
• Urinary and kidney wellness
• Beauty and collagen
• Fitness and nutritional support

It is important to distinguish marketing claims from medically established treatment indications. A supplement’s marketing description does not establish that it can prevent, diagnose, or treat a disease.

Public trademark evidence identifies Shenzhen Shuihaochuan Trading Co., Ltd. as the owner of the Didacat mark. The company is identified as a limited company based in Shenzhen, Guangdong, China.[1]

Historical trademark databases show some variation in ownership details. For example, an older database entry attributes the original U.S. application to an individual named Shirong Lin, while other records identify Shenzhen Shuihaochuan Trading Co., Ltd. as the owner. The latter is supported by the UK Intellectual Property Office record and other current trademark records, making it the preferred reference for the brand’s current corporate association.[2]

Didacat’s trademark activity suggests a concerted effort to establish the brand internationally across multiple jurisdictions.

United States

The U.S. mark was filed in 2020 and registered in 2021 under Class 5.[2]

United Kingdom

The UK trademark UK00004249650 was filed on August 14, 2025, and registered on November 7, 2025. Its specification includes a wide range of vitamin, nutritional, probiotic, protein, and veterinary supplements.

European Union

The EU trademark application 019232640 was filed on August 14, 2025, and recorded as registered on December 5, 2025. The goods specification covers vitamins, minerals, probiotics, nutritional supplements, and supplements for animals.[3]

Indonesia

Indonesian intellectual property records contain a Didacat application in Class 5. Listed goods include glucose dietary supplements, medicated hair lotion, nutritional supplements, cod liver oil, soybean protein supplements, vitamin/mineral/nutritional supplements, and dietary fiber.

Philippines

Didacat products are visible through Philippine e-commerce listings, including offerings for NAC, Vitamin B Complex, and kidney-health supplements. This demonstrates marketplace availability in the Philippines, although marketplace presence alone does not establish that the products are manufactured or officially distributed by a Philippine subsidiary.[2]

The trademark is registered as the word Didacat. Indonesian intellectual property records specifically describe it as a word mark and state that “DIDACAT” is a brand designation rather than a word with a specified translation or linguistic meaning.

Available records do not establish an official meaning behind the name. Any interpretation of the name as a combination of words such as diet, daily, digital, or cat would be speculative unless confirmed by the brand.

Public information about Didacat is comparatively limited relative to large established supplement companies. One independent supplement database lists several Didacat products but states it has insufficient information to calculate a TrustScore and reports no certifications in its database.[4]

This lack of data does not necessarily imply that products are unsafe or ineffective. Rather, it indicates that independent publicly available information regarding testing, certifications, manufacturing standards, and evidence base is limited.

For consumers purchasing supplements online, useful verification points include:

• Manufacturer and importer information
• Complete ingredient and dosage information
• Batch and lot information
• Expiration date
• Appropriate regulatory registration for the country of sale
• Third-party testing or certification where claimed
• Whether health claims are supported by credible evidence
• Whether the seller is an authorised or legitimate distributor

Didacat is best described as an emerging international dietary supplement brand rather than a conventional pharmaceutical company. Its documented history dates to at least 2020, and its trademark portfolio shows an expanding focus on vitamins, nutritional supplements, probiotics, protein products, and related Class 5 goods.[2]

The brand’s strongest publicly documented characteristic is its broad supplement portfolio and international trademark activity. Conversely, publicly available information regarding founders, revenue, manufacturing operations, research programmes, clinical evidence, quality-control systems, and corporate history is relatively sparse. Claims describing Didacat as a major, premium, clinically validated, or highly established supplement company should be treated cautiously unless additional primary documentation becomes available.[2]
