Description
Natural Calcium from Pure Seaweed
Together Health Seaweed Calcium provides calcium from calcified Atlantic red algae, also known as Lithothamnion calcareum.
Unlike many calcium supplements made from rock-derived calcium carbonate, this product provides calcium as part of a natural marine multi-mineral complex.
Why Calcium Matters
Calcium is essential for the maintenance of normal bones and teeth. It also contributes to normal muscle function, normal nerve transmission and normal blood clotting.
Maintaining a good daily intake of calcium is particularly important as we get older, when bone density and muscle function become increasingly important for long-term mobility and independence.
Why Seaweed Calcium?
The calcium in this product comes from 100% seaweed, sustainably harvested from Atlantic waters around Ireland and Iceland.
During its growth phase, the seaweed naturally absorbs minerals from the surrounding seawater. These minerals then calcify into a porous marine mineral structure, providing a natural source of calcium together with a broad spectrum of trace minerals.
A Marine Multi-Mineral Complex
Together Health’s seaweed calcium provides bioactive calcium alongside 72 naturally occurring trace minerals.
This matters because minerals are often easier for the body to recognise and use when they are supplied in a natural, complete food-based matrix rather than as isolated compounds.
A Natural Alternative to Rock-Based Calcium
Many calcium supplements are made from mineral salts such as limestone. Together Health uses seaweed calcium instead, providing a natural, plant-based source that is gentle and easy to take.
Carefully Tested for Purity
Because the seaweed is harvested from the ocean, Together Health tests its calcium carefully for heavy metals, microbes and pathogens, rejecting batches that do not meet their standards.
See the Research tab for more information on calcium, bone health and marine mineral complexes.

Research
Research on Calcium and Marine Mineral Complexes
Calcium is one of the most important minerals in the human body. It is best known for its role in maintaining normal bones and teeth, but it is also involved in muscle function, nerve signalling and blood clotting.
Calcium and Bone Health
Calcium contributes to the maintenance of normal bones and teeth. Adequate calcium intake is especially important throughout adulthood and later life, when maintaining bone density becomes increasingly important.
Calcium and Muscle Function
Calcium contributes to normal muscle function and normal neurotransmission. This makes it important not only for bone structure, but also for everyday movement and physical function.
Why Source Matters
Many calcium supplements use isolated mineral salts such as calcium carbonate or calcium citrate.
Seaweed calcium is different because it is supplied as part of a naturally occurring marine mineral matrix, providing calcium together with 72 trace minerals.
Research into Red Marine Algae
Research into mineral-rich extracts from red marine algae has explored their composition and potential role in supporting bone health.
These extracts are naturally rich in calcium, magnesium and trace minerals, making them different from isolated calcium compounds.
