Developed by a Gastroenterologist

Dr. Alasdair Patrick is a Gastroenterologist in Auckland, New Zealand.  Director of the largest private Gastroenterology Group in NZ (The MacMurray Centre), Dr. Patrick saw patients needing help with weight loss, gut concerns and nutrition.

He witnessed firsthand the health impacts of these concerns and grew alarmed by the lack of integrity in some of the products his patients were trying. Too many claimed effectiveness without scientific backing, contained artificial ingredients laden with preservatives, fillers, and sweeteners, or were manufactured overseas by large multinational corporations.

He decided to do something about it. 

Dr. Patrick has several criteria for all new products:

Plant based

Over 65% of people are dairy intolerant—many don't even realise it. That's why all HealthFx products are dairy-free.

Too many patients came to Dr. Patrick suffering from upset stomachs, constipation, and diarrhoea after using products like Optifast and Optislim, which contain dairy.

Dr. Patrick's solution was simple: replace traditional whey protein and milk powder with carefully selected plant proteins. The result? All HealthFx products are not only vegan but significantly gentler on your digestive system, allowing you to focus on your health journey without digestive discomfort.

Contain no nasties

Many meal replacements and supplements contain artificial flavours, colours, sweeteners, anti-caking agents, and preservatives. When you're using these products long term, this chemical load can disrupt your gut microbiome and overall health.

Dr. Patrick refuses to compromise. Every HealthFx product contains only ingredients that actively support your wellbeing—no cheap fillers, no additives, no shortcuts.

Based on robust clinical science

Many 'health' products on the market are not grounded in strong science.  Fancy instagram ads, a free car or a celebrity endorsement may seem convincing - but it doesn’t mean a product is based on sound medicine. 

Dr. Patrick insists that every ingredient used in HealthFx products be backed up by rigorous science. 

You can read some of the research under each ingredient in the nutritional section.

Dr. Patrick is proud of what HealthFx has achieved. Each product is built on solid science.

We've included only what works—and left out what doesn't.
