Everything you need to know

From what's inside to how it arrives — open any section below for the full picture on Organic Seaweed Powder – Dental & Thyroid Support for Dogs & Cats.

Logan's Pet Supplements Organic Seaweed Powder is a single-ingredient supplement made from Ascophyllum nodosum — a sustainably harvested Atlantic seaweed that has been trusted by pet owners and vets alike for its remarkable dental and thyroid-supporting benefits. Free from additives, fillers, and artificial ingredients, it's as pure and natural as supplementation gets.

Simply sprinkle the recommended amount over your dog's or cat's food each day. The active compounds in the seaweed are absorbed through digestion and travel into your pet's saliva, where they get to work disrupting the bacteria that cause plaque, tartar, and bad breath. No wrestling with a toothbrush — just a daily dusting over their dinner.

Beyond dental health, Ascophyllum nodosum is naturally rich in iodine, which supports healthy thyroid function and overall metabolic balance. It also contains a broad spectrum of vitamins, minerals, and antioxidants that contribute to your pet's general wellbeing. Whether you're tackling a specific concern or simply investing in long-term health, this powder is an easy, effective daily habit.

100% Organic Ascophyllum nodosum (Atlantic seaweed powder)

Sprinkle the recommended amount directly over your pet's food once daily. Cats and dogs up to 15kg: 1/4 teaspoon per day. Dogs 15–30kg: 1/2 teaspoon per day. Dogs over 30kg: 1 teaspoon per day. For best results, use consistently every day. Introduce gradually over the first week if your pet is new to seaweed supplements.

Keep out of reach of children and pets. Store in a cool, dry place away from direct sunlight. Reseal the bag or container tightly after each use. Do not exceed the recommended daily amount. If your pet is pregnant, nursing, or has a known thyroid condition, consult your vet before use. Discontinue use and seek veterinary advice if any adverse reaction occurs.

Free UK delivery on orders over £39. Delivery times vary by product, and we'll email you tracking as soon as your order is on its way.

Common questions

Frequently asked questions

Yes, this organic seaweed powder is suitable for both dogs and cats of all breeds and sizes. It contains a single, natural ingredient — Ascophyllum nodosum — which has been widely used in pet dental supplements and is considered safe for everyday use. Always follow the recommended dosage guidelines for your pet's weight.

Ascophyllum nodosum works by naturally altering the bacterial environment in your pet's mouth. The active compounds are absorbed into the saliva, where they inhibit the bacteria responsible for plaque and tartar build-up. Over time, this helps reduce existing deposits and prevents new ones forming — all without any brushing required.

Most pet owners begin to notice fresher breath within 2 to 4 weeks of daily use. Visible reductions in plaque and tartar build-up typically become apparent after 4 to 8 weeks of consistent supplementation. For best results, add the powder to your pet's food every day without interruption.

Ascophyllum nodosum is a natural source of iodine, which plays an important role in supporting healthy thyroid function. However, if your pet has a diagnosed thyroid condition or is currently on thyroid medication, we strongly recommend consulting your vet before introducing this supplement, as additional iodine may not be appropriate in every case.
