About Us

Metabolics is a relatively small, family run business based in the South West of the UK in Wiltshire and has been operating for over 25 years. We have an excellent team of people, all committed to producing the highest quality nutritional supplements to our customers across the globe.

Quality and purity are the most important elements of how we work here at Metabolics. We use only the best quality raw ingredients to ensure our customers receive only the best quality products.

Our history

Metabolics was founded in 1991 and has been providing the highest quality nutritional and health supplements to our customers ever since. Metabolics specialises in pure nutritional supplements using no binders, flowing agents, caking agents or fillers.

The company was founded by Alison Astill-Smith, a fully registered and experienced Osteopath, having studied at The British School of Osteopathy. Alison was unhappy with the quality of supplements available for use in her practice so decided to establish Metabolics and offer other practitioners and individuals with the best quality nutrition.

Alison also delivers informative seminars across the UK and the rest of Europe, delivering practitioners a wealth of nutritional health and well-being information contributing to their CPD hours.

In April 2016, Metabolics’ sister company, Nutristrength, was launched. Manufacturing out of the same high specification facility in Wiltshire, Nutristrength offers the very best in lifestyle nutrition. Sharing the same ethos of quality ingredients with no artificial additives, Nutristrength’s range of protein powders and food products supports a healthy and active lifestyle.

How we work

Metabolics is fully committed to providing the highest levels of purity and quality in all our supplements.

It all starts with sourcing the best quality raw materials of the highest purity, with next to nothing added to any of our nutritional supplements. We have a saying at Metabolics that applies to all our product range – “Quality out, demands quality in”.

Most of Metabolics encapsulated products contain only the active ingredients and nothing else. When the quantity of the ingredient is too small to create a usable product, we add one filler and one filler only which is “plant cellulose”.

Cellulose is a plant-sourced dietary fibre that the body cannot digest, however, as the active ingredient within the capsule is released and absorbed; the cellulose simply passes harmlessly through the body.

The encapsulating process takes place in our Wiltshire-based manufacturing facility that is state-of-the-art to ensure products are produced to the highest standards. We conduct random batch testing to guarantee all products meet these very high standards, whilst also taking samples following the clean down process of our equipment to ensure there is absolutely no chance of contamination or impacted standards.

Our standards

Nothing is added to our nutritional supplements.

For all Metabolics liquid supplements we only add purified water, purified to 18.2MΩ. This allows us to create liquid supplements with water that is as pure as water can be.

We pride ourselves on the fact that we do not include any hidden fillers, emulsifiers, binders, lubricants or stabilisers within any Metabolics nutritional supplements.

That’s no Magnesium Stearate, Stearic Acid, Polyvinylpyrrolidone and Sodium Carboxymethylcellulose. Nothing that could possibly interfere with the active ingredients found within any of Metabolics products, making them as effective and as pure as possible.

The extras that you find in some other well-known products are not there for your benefit. Some other manufacturers use them to allow them to manufacture products easier, or make them more aesthetically appealing.  What is important to note is that some of those additives are machine lubricants, added to allow the machines to run more smoothly and quickly reducing manufacturing costs.

All of Metabolics machinery is semi-automatic, which means they run without added lubricants and is contained within a state-of-the-art clean room facility.

Clean Room Manufacturing and Quality

At Metabolics, we manufacture all of our products in the UK in our state-of-the-art clean room manufacturing facility. We understand that you, the customer, need to trust the supplements you take, which is why we are so committed to product quality.

As far as we are aware, there is no other UK nutritional supplement manufacturer with the same standard of manufacturing facility.

If you would like to see a short video of our manufacturing facility you can here. The video highlights the lengths we go to ensure the quality of all our products as well as showing a behind-the-scenes look at how we produce our supplements from formulation to encapsulation.


We are also ISO:9001 and ISO:14001 accredited, to help give you the customer confidence in not only Metabolics as a company but also our whole range of nutritional supplements.

Metabolics products are manufactured under strict guidelines of GMP & HACCP certification, a strict set of requirements that ensure food supplements are constantly manufactured and controlled to a high standard. This demonstrates a manufacturers ability to produce supplements that meet the industry’s high standards of quality and safety. In addition to this the business utilises the quality management system ISO 9001:2015 to consistently provide products and services that meet customer and regulatory requirements. We also have ISO 14001:2015 which allows us to measure and improve our environmental impact.
