Spirulina - this is a blue-green algae (cyanobacteria) which is a great source of manganese, copper, iron, B vitamins and antioxidants. It is seen to the one of the most nutrient dense and bioavailable food in the planet. Research in humans has presented benefits such as alleviating symptoms of allergic rhinitis, enhancing glucose metabolism, decreasing triglycerides, and improving fatty liver. A daily dose of 1 to 8 grams has been shown to have some beneficial effects. Learn more about health benefits of Sea Vegetables. It is vital to keep in mind that while spirulina is a protein dense considering its weight, it must not be seen as a main source of dietary protein because the amount needed would be so high for normal or safer consumption.
Chlorella - this is a single cell green algae that is a rich source of chlorophyll, zinc, magnesium iron, vitamins A, C and B12. It must go through a special process where the walls of the cells needs to be broken open for it to be digested by humans. It is valued mainly because of its capability to bind to unwanted chemicals and heavy metals in the body, as a result, it is usually used to help in detoxification. More research are needed regarding the health benefits of chlorella, on the other hand, there are indications that it may be advantageous for the immune system as well as enhancing weight loss.
Kelp - this is probably the most familiar type of sea vegetables. This huge brown seaweed is important because of its high iodine content, which is a nutrient that is not naturally seen in the soil of Southern Ontario. Without iodine in our bodies, we are not able to generate thyroid hormones and could lead to hypothyroidism (low thyroid function) and goiter (swelling of the thyroid gland) can take place. In addition, it is also rich in dietary fiber, vitamin B6, iron, and potassium. In supplement form, this is available as a liquid extract or in capsules.

With regards to food, kelp granules can be utilized as a salty-tasting low sodium content seasoning. 1 teaspoon of kelp granules can give 967 percent of the needed intake for iodine, so be wary of overconsumption.
Kombu - this is available in long dried, folded strips. This is a variety of kelp and is beneficial for enhancing digestibility and decreasing gas-inducing properties of beans and other types of legumes. This is also flavorful so it must be taken in small amounts. Learn more from https://en.wikipedia.org/wiki/Chlorella.
