Did you know that kelp can grow up to 2 feet per day? This makes it one of the fastest-growing organisms on the planet! Fun facts aside, kelp is an important food around the world. It is rich in vitamins and minerals that have been helping people stay healthy for thousands of years. But if you have a cat or dog, you may be wondering to yourself, “Is kelp good for pets?”
The answer is yes! Many pets can benefit from supplements that contain kelp. It’s a natural source of vitamins, minerals, and antioxidants, and can support their health in a few ways. However, before you start using kelp, there are a few things to know about kelp and pets.
The History of Kelp
In the ocean, kelp grows in cool, shallow waters that are full of nutrients. This algae is lovingly munched on by sea turtles, manatees, and more.

Interestingly, kelp is not a plant at all. Even though it looks like a plant, it’s actually a type of large brown algae, from the kingdom Protista. The more you know!
Aside from being popular with marine life, kelp has also long been used as a food. For example, the seaweed used in sushi (called nori) is a type of algae! But you can also find kelp in soups, salads, flavorings, and more.
In herbalism, many holistic healers look to kelp thanks to its high mineral content. In fact, kelp has over 60 minerals that may help pets with skin, coat, digestion, and more.
One of the most common uses for kelp is as a support for pets with thyroid issues. Kelp is a natural source of iodine, and some research proposes that it could be used as a natural treatment for hypothyroidism caused by iodine deficiency.
Safety of Kelp for Pets

Kelp is safe for pets and can even be beneficial for them in the right quantities. It is rich in vitamins and minerals that may help in various areas of pet health and well-being. However, always be sure to give kelp in an amount that is safe for pets. For example, NHV supplements contain only vet-approved doses of kelp and other herbal ingredients.
Like any supplement, it is best to consult a veterinarian if your pet is lactating or pregnant before starting.
The dosage and quality of the herbal ingredient are crucial for safety and efficacy. We advise against using any herb without proper guidance and under the supervision of your pet’s veterinary team. NHV formulas are meticulously researched and made in a GMP-certified facility using only the highest quality organic or ethically harvested herbs. Each formulation was expertly developed by a holistic veterinarian and a master herbalist with a combined 50 years of experience in plant-based remedies. Through dedication and research, NHV formulations are safe and effective in extracting the medicinal properties of the herb through a patented process.
Using Kelp Supplements for Pets
When choosing a kelp supplement for your fur kiddo, make sure you choose supplements specifically made for pets because human supplements may not contain the right amount. NHV supplements are human-grade ingredients, but they are in vet-approved amounts appropriate for pets.
If you need support for pet hypothyroidism, then choose NHV Thyro-Up
Your next choice in supplements will depend on your overall goal in using kelp for pets. If you need support for pet hypothyroidism, then choose NHV Thyro-Up. If you are looking for overall metabolism support, then choose NHV Multi Essentials.
NHV Thyro-Up is a blend of nine herbs, each chosen to help support an area of health and wellness in pets with hypothyroidism. Eleuthero may help balance the thyroid, cayenne encourages circulation, and of course kelp naturally contains iodine, which may help stimulate underactive thyroids.
NHV Multi Essentials is designed to help round out your pet’s dietary intake. It has a blend of herbs rich in vitamins and minerals such as alfalfa, Asian ginseng, kelp, and more. It can be added directly to their food for a daily nutritive top-up.

Natural Support for Thyroid Problems in Dogs and Cats
Hypothyroidism (underactive thyroid) is a condition that affects many pets, including dogs and cats. Apart from slowing down, if you notice that your little one’s fur is thinning, their skin is dry and dull or they have sudden weight gain, you may want to book a visit with your vet to run some tests, including a TT4 test, which is a measurement of thyroid hormone levels in the blood.
For pets suffering with hypothyroidism, we'd suggest adding natural pet thyroid supplements like our Thyro-Up and Multi Essentials to support their glandular system as well as support their metabolism.
How NHV Supplements Provide Glandular Support And Aid Digestion
Hypothyroidism can cause a lot of discomfort for your pet. If left untreated, hypothyroidism may lead to secondary health issues like cardiovascular disease. Ingredients like eleuthero and ginkgo support healthy thyroid function, and brain function. Kelp is rich in iodine which helps activate the thyroid gland while ingredients like licorice and gotu kola contain many beneficial properties for stimulating thyroid hormone production. The antioxidant and sedative properties in Thyro Up help to protect the body from cell damage, and help to soothe inflammation and discomfort. Multi Essentials contains a range of vitamins, minerals and trace elements that are formulated to help stimulate metabolism, promote healthy skin/coat, improve digestion, energy levels and help to fill nutritional voids.
