    We want to support the health of the whole family through supplements. Our mission is to help you and your dogs and cats share more happy moments together.

  • Let’s think about immunity

    Immunity is the body’s ability to defend itself and distinguish what is good for it from what is harmful. When the immune system is in balance, the body can absorb what it needs and eliminate what it does not. Helping our loved ones maintain that balance is one of the things we can do for them now.

  • Food matters for pets, too

    Like us, pets build their bodies from the food they eat every day. Good food is a gentle form of care. Instead of commercial food that is high in carbohydrates, consider homemade meals for dogs and cats to support their health. If cooking every day is difficult, we also introduce carefully selected premium foods that are high in protein.

  • 走る喜び、ずっと一緒に。関節・腎臓・心血管にクリルオイル

    Keep the joy of running together

    Monolith Krill Oil is made from Antarctic krill from the clean waters of the Southern Ocean. Made with 100% Antarctic krill, it is a high-quality oil rich in nutrients. It contains omega-3 fatty acids, which are important for the body, and is readily absorbed. It is an option for dogs and cats whose owners are concerned about their joints, cardiovascular health or kidneys.

  • Why amino acids matter for senior pets and pets with kidney concerns

    Aminofine is an amino acid supplement specially developed for dogs and cats with safety in mind. Amino acids are essential for maintaining muscle and strength. When they are lacking, the body may break down muscle to obtain them. This supplement helps provide a balanced intake of amino acids.

  • Placenta: supporting liver and skin health

    This placenta supplement helps support liver health, energy and appetite. It contains domestically sourced SPF pig placenta and a range of supporting ingredients. It may be useful when your pet takes medication or when you want to care for their skin and coat. Owners who enjoy a drink may also want to consider liver care for themselves.

  • Skin concerns: itching, redness, dryness, dandruff and lumps

    Dogs’ and cats’ skin is delicate and can be affected by their environment and seasonal changes. Redness, dry coats, dandruff and lumps may relate to diet, surroundings or allergies. Alongside daily checks and care, supplements can provide additional support.

  • Weight concerns: overweight pets and dieting

    More dogs and cats are said to be gaining excess weight. Extra weight can put strain on joints and the heart and affect movement. Owners can help by providing a balanced diet and suitable exercise, and by managing their pets’ weight.
