  • 1 oz  Dried Raw Irish Sea Moss (about 29 grams when weighed)
  • Spring or Alkaline water for cleaning and soaking

Optional Add-ins

  • 1 tbsp Bladderwrack Powder
  • 2 tbsp Spirulina Powder


Prepare and Wash Sea Moss

  • Place the dried sea moss in a large bowl, cover it with water, and massage the sea moss. Be sure to remove any visible dirt and debris. Drain and repeat this step once more.
  • Place the sea moss in a large bowl and cover it with filtered or spring water. (do not use tap water) Make sure all the parts of the sea moss are covered. Allow the sea moss to soak for 12-24 hours. (at room temperature)

Boiling The Sea Moss (2 Ways):

  • Drain the sea moss from the water. Then, add the sea moss to a medium sized saucepan and then add water until the water is about an half inch over the sea moss. 
  • Bring the saucepan to a boil, then reduce the heat to a simmer. Continously stir the sea moss for 10-15 minutes, or until the sea moss fully breaks down (some small clumps are okay). 
  • Optional: Remove the sea moss from the heat. Stir in spirulina powder and bladderwrack. Mix until fully combined.

Second Method:

  • Drain the sea moss from the water. Transfer the soaked sea moss to a medium saucepan filled with water. Bring it to a low boil over medium heat, then reduce to a simmer for 10-15 minutes or until soft. 
  • Remove the sea moss from the heat and strain the water and reserve it for blending. Transfer the sea moss to a heat-safe blender then add water until the water is about an half inch over the sea moss (or more depending on your desired consistency).
  • Blend the sea moss until smooth. Add water and blend to reach your desired consistency. (Make sure to allow the steam to escape from the top and use a heat tolerant blender to avoid injury)
  • Optional: Add in spirulina powder and bladderwrack. Blend once more until fully combined.

Storing The Sea Moss Gel

  • Transfer the Sea Moss gel into a mason jar. Allow the gel to cool at room temperature for at least 30 minutes. Then, seal the jar and transfer it to the fridge. Store in the refrigerator for up to 2-4 weeks or in the freezer for up to 3 month
  • Enjoy 1-2 tablespoons a day in smoothies, tea, coffee, soups, jams, etc.


STORE: Store Sea Moss Gel in an airtight container. It can last in the fridge for up to 1 month. You can store it in the freezer for up to 3 months. You can also pour it into an ice-cube tray and freeze the sea moss for later use. This is perfect for taking the cubes and throwing them into your smoothies.
What does spoiled sea moss smell like? Always be mindful of checking your sea moss gel before consuming it. Storing conditions vary and can impact how long the sea moss gel will last and be safe for consumption. If you open your sea moss gel and it has a pungent fishy smell, smells sour, or has any signs of molding or discoloration, this indicates that the sea moss has spoiled. Do not consume it and make sure to immediately throw it in the trash.
HOW MUCH TO TAKE: The recommended amount of Sea Moss Gel to take daily is 1-2 tablespoons per day.
