100% Pure & Natural New Zealand Seaweed/Kelp

'where only the best will do'

Our pure, clean and nutrient rich waters are absorbed into the seaweed which in turn produce 'world class seaweed’.  Because it absorbs the nutrients from its surrounding marine environment we can guarantee that this seaweed is one of the best kelp varieties in the world.



What is brown kelp?

Kelp, commonly referred to as seaweed, grows in shallow nutrient-rich salt water along many coastlines around the world. Botanically, this plant is classified as algae. It is a rich source of natural vitamins and minerals, including essential trace minerals. Seaweed is dependent upon the sea for its nourishment - an excellent source since the sea is the repository of all the minerals that have been washed from the land through the millennia.


How is seaweed harvested?

Macrocystis can grow as much as two feet per day. Seaweeds environmental requirements are sea water, light for photosynthesis, a firm attachment, and dependant upon the sea for its nourishment (they have an excellent ability to take up minerals from the water and hold onto these minerals in their cells).  Historically, seaweed has been readily available, accessible and a food source that has been consumed by coastal communities for centuries.


Note:  Only purchase seaweed from a reputable and organic supplier - it is important to know where your seaweed is harvested from.  Seaweed absorbs the nutrients as well as nasty pollutants and chemicals from the growing area. heavy metals levels in seaweed can really vary between batches and harvest location. Use a reputable company that tests their products for contaminants.


What is the science behind seaweed's health properties? 

Awareness and research around seaweed have been growing over the past 5-10 years, even though it has been used in cultural and historical healing purposes for hundreds of years it isn’t until fairly recently that seaweed has captured the attention of the cosmetic, health and skin care global and national industries.


The strong photosynthesis of algae creates a large affinity for nutrients – absorbed directly from sunlight and ocean nutrients (far greater than any earth vegetable). Brown seaweed is considered the number one food high concentration of iodine - iodine is required to balance and keep the thyroid function healthy and active - to help with digestive system, mental and physical energy levels.


What vitamins and minerals are found in seaweed?

Macrocystis pyrifera Seaweed (Brown southern Pacific Kelp/seaweed) (what Oceangreen Organics use in their supplement range) contains a unique and comprehensive combination of all 56 minerals, vitamins, electrolytes and trace elements – including notable amounts of, iodine, calcium, magnesium, potassium, iodine, iron, and zinc, , potassium, bromine, iron, sodium, phosphorous, magnesium, align, mucopolysaccharides, histamine, and vitamins A, B-1,B-2, C, D and E. together with important trace elements such as selenium (that are somewhat lacking in land vegetables, due to soil demineralisation).  


A truly natural, pure superfood from the ocean.  The nutrients found in seaweed help support numerous structures and functions throughout the entire human body.


Current research of the unique properties of seaweed make it beneficial to the body in several ways - claims and research findings have identified and highlighted numerous healing and topical health properties.  Worldwide research is continuously being done and Macrocystis seaweed has been found to be the most beneficial type. This research has identified significant features and benefits to human health. Read more about Macrocystis here. 


Why is kelp good for you?

Kelp Supports a Healthy Metabolism. Seaweed / Kelp is a natural super food loaded with trace minerals, amino acids, vitamins, and minerals. Most notably, kelp is a rich, natural source of iodine which can provide adequate levels to stimulate a sluggish thyroid and encourage a healthy metabolism.  The unique properties of seaweed make it beneficial to the body in several ways:


What is fucoidan

Fucoidan is a substance found in the cell walls of certain seaweed species that is used medicinally for a wide variety of health purposes. You might take fucoidan to help treat high blood pressure, infections or allergies.


The National Institutes of Health (NIH) say that brown seaweed is one of the best natural food sources of iodine  -  an essential component in thyroid hormone production.

The mineral content in sea vegetables (seaweed) is about 10 times higher than that of garden vegetables. Seaweed is packed full of chlorophyll and soluble dietary fibre - with a balanced combination of minerals including potassium, phosphorus, iron, calcium, magnesium and iodine.  Calcium and magnesium together regulate many functions - including muscles and the nervous system and iodine is essential for human health.


Macrocystis pyrifera seaweed is one of the most nutrient-rich algae on the planet.  It grows in the nutrient-dense ocean waters off the Southern Pacific shores of New Zealand. New Zealand's clean waters are a nutrient-rich treasure chest which the seaweed thrives on pulling high concentrations through their leafy blades. 


Brown Kelp/Seaweed has more calcium than many vegetables, including Kale and collard greens.  Calcium is important to maintain strong bones and optimal muscle function.

According to George Mateljan Foundation - "Iodine is a key component of the hormones made in the thyroid gland.  These hormones are absolutely critical to human health, helping to control energy production and utilisation in nearly every cell of the body"
