1. What is Lithothamnium?
Lithothamnium is a calcified red seaweed that grows naturally on the volcanic seabed in cold, clean ocean waters, such as those off the coast of Iceland. It develops slowly, adding only fractions of a millimeter each year, and absorbs calcium, magnesium, and over 70 trace elements directly from seawater. These minerals become part of its porous, honeycomb-like cell walls, creating a highly bioavailable mineral source.

2. Natural Formation and Harvesting
When Lithothamnium dies, its calcified fragments detach from the seabed and accumulate into mineral-rich deposits. These deposits are carefully and sustainably harvested using gentle methods that only collect naturally detached fragments. After drying and milling, the seaweed is transformed into a natural, mineral-rich product suitable for animal nutrition.

3. Mineral Content and Structure
Lithothamnium contains 30% calcium, 2% magnesium, and a wide range of essential trace elements. Its unique honeycomb structure provides an exceptionally high surface area of 12 m² per gram, making it a highly reactive calcium source and a natural conditioner for rumen bacteria. This structure helps stabilize rumen pH and improves digestion.

4. Benefits for Cow Health

• Transition Period Support: During the dry and transition periods, cows are particularly vulnerable to metabolic disorders such as milk fever (hypocalcemia). Feeding Lithothamnium supports calcium balance, reduces pH fluctuations in the rumen, and helps maintain a negative cation-anion balance (CAB) without affecting overall ration formulation.

• Rumen Health: The bioavailable minerals and structure of Lithothamnium stimulate beneficial rumen bacteria, supporting fiber digestion and improving feed efficiency.

• Performance and Productivity: Research shows that cows fed Lithothamnium after calving exhibit improved milk production, milk components, and overall profitability.

5. Additional Benefits
In addition to mineral support, the species used in our products has anti-inflammatory properties, promoting overall gut health and contributing to a healthier, more resilient animal. Lithothamnium also allows for extra flexibility in feed formulations, creating room for other nutrients.

Conclusion
Lithothamnium is a 100% natural, sustainable, and highly effective source of calcium, magnesium, and trace minerals. Its benefits extend from rumen health to overall cow performance, making it an essential ingredient in our lick blocks, premixes, and buffers.
