Everything You Need To Know About Sea Cucumbers

by Carly Neubert, BA, NC on June 15, 2022

All families have a stand-out member that seems to outshine everyone else.  Some families have great athletes, musicians, or academics. The Carey family has Mariah, the Williams have Serena and Venus, and the Einstein family has Albert. The echinoderm family has the sea cucumber.

Sea cucumbers can be found in all the oceans around the world. There are over 1700 different species of sea cucumber. They have been eaten and used as medicine for thousands of years. During the Ming and Qing dynasties, they were referred to as “sea ginseng,” because they are so nutritious. They get their name because they have long cylindrical bodies shaped like cucumbers. They don’t have brains, but what they lack in intellect they make up for in nutrients. 

I would definitely consider sea cucumber a superfood, although it is unlikely that most people would want to introduce it into their daily diet. I suggest using Deep Blue Health Immuno 5+ Sea Cucumber supplements instead. 

Deep Blue Health uses sea cucumbers harvested from the floors of the Pacific Ocean. Specifically, they are sustainably harvested in Aotearoa New Zealand and off the coast of Fiji. 

Sea Cucumber Nutrients

What kind of nutrients are contained within a sea cucumber? There is more than you may think! Zinc, Iron, Calcium, Vitamin A & B, Lectins, and more!

What about potential health issues that can benefit from nutrients found in sea cucumber? Here are some, to name a few:

  • Angiogenesis
  • Cancer
  • Tumors
  • Hypertension
  • Inflammation
  • Osteoarthritis
  • Antibacterial
  • Antiviral
  • Antioxidant
  • Antithrombotic
  • Wound healing properties

What about sea cucumber helps my immune system?

The chondroitin sulfate and triterpenoids are the substances in sea cucumbers that help your immune cells. Sea cucumber is very high in protein and collagen which makes them an ideal food or supplement for joint, muscle, and skin health. Collagen is excellent healing food and a supplement for Leaky gut. The triterpene glycosides or saponins are the compounds that have been shown to kill cancer cells in a lab setting.  

The amino acid glycine is conditionally essential which means your own body produces it. However, it is crucial for many body functions and your body may not be able to produce enough glycine in times or stress, illness, or growth.  Glutamate is another conditionally essential amino acid.  

Both glycine and glutamate are needed for cells to make glutathione and natural killer cells (NK). Natural killer cells are like the body guard cells for your immune system. They are responsible for attacking and killing viruses, bacteria, and tumor cells.  

Studies show that cancer patients have low arginine levelsThe consequence of low arginine levels is low T-cells which are responsible for recognizing cancer cells within your body.  

It acts as an ACE inhibitor and reduces blood pressure and thins your blood. 

Sea cucumbers are high in chondroitin and collagen which are needed for joint aches and pains. 

Immuno 5+ Sea Cucumber by Deep Blue Health also contains vitamin B6, vitamin C, zinc and magnesium.  

Vitamin B6 is included because it helps your body make new red blood cells and transport oxygen throughout your body. This B vitamin is also responsible for making many immune cells such as T cells and interleukin-2. B6 is vital for the health of your intestinal barrier (gut).   

Zinc is included because it helps your immune cells fight infections. Zinc is also used to make immune cells like T-cells and white blood cells. You can read more of the hundreds of benefits of zinc in this past blog post. 

Magnesium is included in this formula because it reduces cytokine production. Cytokines lead to inflammation and the resulting damage to cells, tissues, and organs.  

Vitamin C, ascorbic acid, is included in this Immuno 5+ also contains Vitamin C as ascorbic acid. It is a critical nutrient for its support for your immune cells and its antioxidant strength.  Vitamin C also protects your gut lining and skin cells.  


What is in Immuno 5+ Sea Cucumber supplements?  

After sustainably harvesting sea cucumbers, they are gutted and cleaned. It is important to remove the gut and interior organs to remove any toxin matter. It is crucial to clean and inspect sea cucumbers multiple times because they move along the ocean floor sucking up and accumulating  debris. The nutrients are found in the fleshy body of the sea cucumber, not in the discarded interior organs.  

After the sea cucumbers are cleaned, they are freeze dried and milled.  They are inspected before being encapsulated. There are no solvents, including ethanol or methanol, used to process the sea cucumbers.

They are not vegetables. They are shaped like a cucumber and that is how they got their name.  Sea cucumbers use their tentacle-like tube feet for moving and for eating. They are invertebrates. They are squishy echinoderms. They are related to starfish, sea urchins and sand dollars, but their skin is much softer and leathery. They range in size from 1 inch to over 6 feet in length. Their body tissue is gelatinous and has the consistency of cooked okra or eggplant.

According to the culinary blogs I read, sea cucumber actually tastes pretty good.  However, if you are looking for therapeutic doses of the nutrients in sea cucumbers, you will need to rely on a high quality supplement like Deep Blue Health Immuno 5+ Sea Cucumber.
