Vision Defender supplements are made in the UK in facilities that follow GMP (Good Manufacturing Practice).
What GMP means:
GMP is a set of manufacturing standards designed to help make sure products are made:
-
cleanly (to reduce contamination risk)
-
consistently (so each batch is made the same way)
-
accurately (so the right ingredients go in, in the right amounts)
-
with clear records (so everything can be checked and traced)
In other words, GMP is about doing things properly, every time — and being able to prove it with documented checks and records.

How GMP helps check ingredients:
GMP systems include controls such as:
-
Approved suppliers and documented purchasing standards
-
Incoming ingredient checks before anything is used (with records kept)
-
Correct storage conditions where needed (to protect ingredient quality)
-
Traceability, so ingredients can be linked to a specific finished batch
How GMP helps check the finished product:
GMP also focuses on the manufacturing and packing stages, typically including:
-
Written procedures for each step (mixing, filling, packing)
-
In-process checks during production (to spot issues early)
-
Hygiene and cleaning controls to reduce contamination risk
-
Batch records so every batch has a clear manufacturing history
Traceability (why batch codes matter):
With GMP record-keeping, each production run is linked to a batch number, helping with:
-
consistency from batch to batch
-
answering product queries
-
effective action if a batch ever needs reviewing
Independent oversight and inspections:
Vision Defender eye health supplements are made in GMP-certified manufacturing facilities that are subject to independent inspections by authorities such as the UK Medicines and Healthcare products Regulatory Agency (MHRA) and the Food Standards Agency (FSA). The manufacturing facilities are also USA FDA (Food and Drug Administration) registered, and so may also be inspected by the FDA.
Why this matters:
When you choose Vision Defender, you’re choosing supplements made with a strong emphasis on consistency, traceability, and quality controls — not just on the label, but in the way each batch is produced.
