Biosea Vet FAQ

Here are some common questions about BioSea Vet.  More specific and detailed information are in the various news articles on the site. The detailed BioSea Vet label is here (Click Here)

Is Seaweed safe for Animals

Seaweed is safe for most animals and trials over the past 20 years show seaweed can be up to 10% of animal feed without any issue. Some seaweed (e.g. Asparagopsis species) are  being researched in ruminants to prevent methane production in ruminants. Most recent studies have shown strong animal health outcomes and in some trials replacement of Zinc and / or antibiotics.

For centuries, seaweed has been a component of diet to animals and humans. Most studies show increased growth rates, improved health and well-being.


Some fresh water turtles and reptiles may have some adverse effects from seaweed as seaweed has high levels of potassium (K).  While there is no data in the literature, potassium is generally in the range of 2 to 8 mmol/l. Hypokalaemia in reptiles will occur from inadequate intake or excessive loss (diarrhoea). In mammals hyperkalaemia may occur with excessive potassium intake, decreased secretion or shift from intracellular to extracellular fluid (e.g. severe acidosis)

Risk of Heavy Metals in Biosea

Seaweeds are really good at sucking up chemicals in the water. Where we grow seaweed we test the water and the seaweed and we do not have detectable levels of lead, cadmium or mercury. We do not ship any product that has more than detectable levels. Why eat to be healthy but then ingest levels of toxic chemicals.

But in some areas and for some species they do concentrate and are used in water remediation. There is seaweed grown in the mouth of the Rhine River to extract out nitrogen, lead, cadmium to reduce the levels going into the North Sea.

Other seaweed is not harvested but washes up on the shore after storms.  In contrast our seaweed is grown in the clean sea (monitored), harvested and processes.

All with the latest state of the art gate to plate tracking process and formally organically certified.

So be careful of seaweed products is grown in river mouths, or is not carefully monitored.
