Compare every Aquamin MG product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.
The magnesium form of Aquamin — a marine-source magnesium (with trace minerals) derived from seawater rather than made synthetically.
We rank Aquamin MG by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Aquamin MG is a form of magnesium sourced from seawater. Unlike many supplements, it is a marine-source magnesium that includes trace minerals rather than being made synthetically in a lab.
The main difference is the source and the consistency. While generic magnesium is often a synthetic chemical compound, this version is derived from the ocean. Because it is a branded extract, it provides a guaranteed level of consistency across every batch that generic, unbranded marine minerals may lack.
Supplement companies use this branded ingredient to avoid the complex process of sourcing and testing their own seawater extracts. By paying for the brand name, they get a pre-standardised ingredient and can use the recognised name on their packaging to signal quality to the customer.
A branded name on a label does not automatically mean the product contains an effective amount. Some brands may include a branded ingredient as a "token" amount to put the logo on the bottle, even if the actual dose is too low to provide a significant benefit.
