Collection: Sea Moss

Alkaline Herb Shop is your source for organic, wildcrafted Irish sea moss (Chondrus crispus), a sea vegetable harvested from cold ocean waters where it grows naturally on rocks and reefs, rather than farmed on ropes in warm pools like many commercial varieties. Every batch is third party tested and ships from the USA.

Buy sea moss here in whatever form fits you: whole raw sea moss for making your own gel at home, ready to use capsules, and blends with bladderwrack and burdock root. From raw sea moss for smoothies and recipes to the convenience of capsules, it is in stock and ready to ship.

Our sea moss supplements are third party tested for identity, microbials, and heavy metals, and we also test them for minerals including iodine and iron. Iodine supports normal thyroid function and healthy skin, and iron supports the normal formation of red blood cells and helps reduce tiredness and fatigue.*

How is Our Sea Moss Harvested?

We use only wildcrafted Chondrus crispus, a type of sea moss that naturally grows in cold North Atlantic waters. This species anchors to ocean rocks and absorbs trace minerals from its marine environment. Chondrus crispus is traditionally valued for its natural growing conditions and is known for its robust nutrient profile.

We do not use sea moss that is farmed in warm-water regions such as the Caribbean or China. These varieties are often cultivated on ropes in shallow waters or pools for mass production and may have different mineral characteristics due to their growing environment.

Our supplements are made exclusively with wild-harvested sea moss, carefully selected for quality, traceability, and consistency.

Our Sea Moss Supplements are Third Party Tested

We conduct third-party lab tests for heavy metals, identity, and microbials to help ensure the quality and safety of our sea moss capsules. Testing for trace metals is a critical step, as even small amounts may pose a risk if not properly monitored. Since trace metals can be found in all foods, including vegetables, we test each batch twice, once upon the raw material arrival and again through an independent third-party lab after the product has been encapsulated. This double-checking process helps verify that our sea moss capsules meet our internal safety and quality standards.
