Lab Testing
Independent Laboratory Testing & Quality Assurance
At Mighton's, product purity, safety, and transparency are central to everything we make. Because sea moss naturally absorbs minerals and trace elements from marine waters, third-party laboratory verification is essential. We work with independent, accredited laboratories in the United Kingdom to test our sea moss rigorously before it reaches your door.
Accredited UK Testing Standards
Our testing is conducted by M.S. Laboratories Ltd, an established analytical facility with over four decades of service. The laboratory operates under strict UK food testing frameworks.
UKAS Accredited
Chemical and microbiological laboratories have held United Kingdom Accreditation Service (UKAS) accreditation since 1996.PDF
Retailer Approved
The testing facility holds Retailer Supplementary Audit (RSA) scopes of compliance for major UK retailers, including Marks & Spencer and Tesco.
Independent Verification
Every sample is analysed independently to guarantee objective, verifiable results for our batches.PDF
Heavy Metal Analysis (Certificate of Analysis Breakdown)
Marine botanicals must comply with strict safety thresholds under UK and European food regulations. Below is the summary of our Certificate of Analysis (Report Ref: CR66566) conducted on Mighton's Sea Moss.PDF
| Tested parameter | Chemical symbol | Lab result (mg/kg) | Food safety context |
|---|---|---|---|
| Lead | Pb | 0.07 | Well below the standard UK/EU maximum threshold (3.00 mg/kg). |
| Mercury | Hg | 0.01 | Exceptional purity; virtually non-detectable (limit: 0.10 mg/kg). |
| Cadmium | Cd | 0.72 | Significantly below the maximum allowable limit (3.00 mg/kg). |
| Total arsenic | As | 5.78 | Normal natural marine level, predominantly harmless organic arsenic. |

Why Source Matters: The St Lucian Difference
The clean laboratory profile of our sea moss is a direct result of where and how it is harvested. Our gold sea moss is naturally grown and sustainably harvested in the unpolluted coastal waters of St Lucia in the Caribbean. Thriving far from commercial shipping lanes, heavy industrial operations, and agricultural run-off, our sea moss develops in pure, mineral-rich seawater before being sun-dried and imported to the UK.
Microbiological & Freshness Standards
Alongside heavy metal screening, Mighton's maintains precise hygiene and preparation standards across our product range.
- Pure ingredients: prepared using only natural spring water, soaked St Lucian sea moss, and genuine fruit or raw honey.
- Zero artificial preservatives: free from artificial thickeners, chemical preservatives, and synthetic stabilisers.
- Insulated transit: dispatched in thermal packaging to maintain freshness and product integrity during delivery.
Frequently Asked Questions
Why is third-party lab testing necessary for sea moss?
Sea moss is a natural bioaccumulator, meaning it draws trace minerals directly from ocean water. Independent testing confirms that the waters where our sea moss grew were clean and free from unsafe levels of industrial heavy metals.
What is the difference between organic and inorganic arsenic in sea moss?
Seaweeds naturally contain arsenic absorbed from oceanic salts. The majority of arsenic found in marine plants is organic arsenic (such as arsenosugars and arsenobetaine), which is non-toxic and passes safely through the digestive system.
How often is Mighton's sea moss tested?
We conduct routine laboratory testing across our batches to ensure that every jar delivered meets strict UK food safety regulations and customer expectations for quality.
