The dietary supplement industry is widely unregulated and manufacturers often promote products without scientific substantiation for their claims at the risk of being caught, which rarely happens. Aquamin is a unique marine multi-mineral complex which contains bio-active calcium, magnesium, plus 72 trace minerals. Aquamin is produced from Lithothamnion, the rare red seaweed and is harvested under exclusive licence by Marigot in the pristine waters off the north-west coast of Iceland. Aquamin is the trademarked name for a range of marine minerals manufactured and supplied by Marigot Ltd. The products are grouped into two categories depending upon their source. Aquamin has been studied in human trials at different dosage points. The products are often used to provide calcium fortification of products and the daily RDI for this vital mineral is a good measure of use; as part of a balanced diet.
