Kelp Powder (Raw, New Zealand wild harvested)


Our Kelp Powder is ground from kelp seaweed which has been harvested from the North Island of New Zealand, dried naturally to preserve nutrients, milled then tested for contaminants. It is raw and unflavoured.

Kelp powder is a highly nutritious funcitonal food, primarily for it’s high iodine content, but many following a lower sodium diet use kelp powder as an alternative to processed table salt as it offers a naturally salty flavour with high micronutrients and lower sodium content. Simply add it to your smoothie, mix it in with your breakfast, or experiment with the array of recipes provided below.

Kelp has a natural umami flavour so makes an excellent seasoning. For the vegan or vegetarian, kelp offers an array of micronutrients which may otherwise be difficult to find in non-animal protein sources.

Ingredients:  (Ecklonia radiata) seaweed 100%.

How to use Kelp Powder

How to Use Kelp Powder?

Sprinkle in porridge or add to a smoothie. Adds body and salty, sweet umami flavour to soups, stews and gravies. Use it to replace regular table salt.

Kelp also contains enzymes which can soften the walls of meat and beans so makes an excellent ingredient in marinades to tenderise and add umami flavour. It is also said to ease flatulence!

You could also try our plain kelp seasoning which is essentially the same as this kelp powder but milled into granules rather than powder.

Explore our range of naturally seasoned kelps – garlic, lemon and chilli if you are looking for novel and interesting seasoning ingredients which add wonderful nutrients and flavour to meals.

Check our recipe section for inspiration on using kelp powder in your food. We have a wide range of other products containing New Zealand Kelp.

A word of warning: Kelp offers an insane amount of naturally occurring iodine. Please pay attention to the serving size suggestions on pack and consult a health care professional if you have concerns about your health or further questions about iodine. Each person’s iodine tolerance is unique.

Health Benefits

Benefits of Kelp Powder?

Kelp is a brown seaweed and widely regarded as the best natural, most concentrated source of iodine – an essential nutrient for human health – specifically linked to immunity, thyroid, brain, ovarian and breast health. Iodine is an essential nutrient for the production of a hormone called thyroxin which helps to regulate many body functions. It has also been linked to apoptosis (cell death) which is critical to fighting cancer – particularly thyroid and breast cancer.

We like to refer to this Harvard study, which encourages improving diet in the first instance, before adding made-made nutritional supplements. Most nutrients are more potent when they come from our food and have not been processed in a lab. Plus, food tastes better and is often cheaper than nutritional supplements, not to mention less of a hassle as you can simply add it to what you are already eating or preparing to eat.

In addition to iodine, Kelp offers a range of other nutrients (such as calcium and magnesium) and beneficial compounds  including Alginates, fucoidan, laminarins and lignans.

Harvesting, testing, packing, Recylcing

How we harvest, test our pack our Kelp Powder

Our kelp is wild harvested from the pristine waters of the North island of New Zealand, then air dried naturally to preserve it’s dense nutritional value before being milled into a fine powder.

Pacific Harvest specialises in seaweed, and has been trusted by the nutritional community since 2002.  We test all our kelp for contaminants in external labs, before packing them by hand in our food grade facility in Auckland.

We recently removed the zip lock from our refill bags to reduce the amount of overall plastic in the bag. Please use the resealable sticker we provide to keep moisture out. If you are purchasing the bulk kelp bags, please keep them sealed after you have opened them as they will atract atmospheric moisture and may become sticky.

Recycling our packaging

We recently added cardboard boxes to our range to ensure the stores who stock these products can stand them on shelf as the pouches we previously used fell over constantly! Please pop the boxes into your worm farm, or in kerb side cardboard recycling.

The plastic pouch in the refill box and bulk bag can be recycled through soft plastic recycling schemes. Ideally we’d not use plastic but as seaweeds are hygroscopic (attract moisture) we need to ensure we can keep the seaweeds food safe. Compostable options don’t currently provide adequate moisture barriers.

The jar is reusable, or refillable. If you don’t have a need for it, please discard in your household recycling.  Please read more on our packaging journey here.
