our difference:



We carefully choose our formulations based on strong scientific backing. We also combine clinical evidence from many trials with knowledge of age old traditional Ayurvedic and Chinese medicinal uses.



The bioactive compounds are extracted from plants and concentrated to a therapeutic dose. We combine the extracts and add them to capsules. There are no nasty fillers, toxins, preservatives, sweeteners or caking agents. Our capsules are vegan, gluten-free and non-GMO.



Our packaging is completely recyclable, and infinitely reusable. We have a refill pouch that you can pour into your beautiful MIRON glass jar. The pouches are great from travelling too. Our ingredients are responsible sourced from all around the world and manufactured in Australia.

Quote from the founder:

“I believe everybody wants to improve their health, but it’s hard to know which supplements are right for you, if you come along this journey with me you will learn exactly what you are taking and why it will benefit you specifically and that all you need is one daily dose of STMNA”.

We completed a pre-launch trial of our product 'Healthspan'.

This is what some of them had to say:

No more Nurofen

Rated 5 out of 5

I play hockey and had got into the bad habit of taking Nurofen before and after each game to manage stiffness and joint pain in my knees. Taking STMNA has enabled me to break the habit as I have had significant reduction in inflammation. No more Nurofen for me! Notably better sleep quality and more energy as well.

No afternoon crash!

Rated 5 out of 5

After taking STMNA I have noticed longer lasting energy levels and less of a crash in the afternoon. This has been great as I do night shifts, I love knowing exactly where the ingredients come from and the fact they work together and benefit each other.

Great sleep and more concentration

Rated 5 out of 5

I have been struggling with insomnia for years, but after a few weeks of STMNA I was finally getting a good nights sleep. I have also been waking up feeling well rested each day. I have noticed an increase in concentration throughout the day too.

Mental clarity and energy

Rated 5 out of 5

I have battled with exhaustion and brain fog for many years, throwing every aspect of my daily life into disarray. Since taking STMNA I have found more energy throughout the day, helping me return to and maintain routine. Now I’ve finally got back the mental clarity and concentration I have been searching so long for.

All up - great result!

Rated 5 out of 5

“I subscribed to STMNA Bioactives because I liked the idea of natural treatments for common ailments with the view to ultimately coming off my prescription medication.
I have to say that since taking STMNA Bioactives I have experienced better blood circulation, and found my gut health improved as well as improved sleep and energy levels.
My GP has been supportive and I’m working with him to wean myself off the prescription meds. All up – a great result.”

Reduced inflammation and improved digestion

Rated 5 out of 5

I have really been noticing reduced inflammation in my body, around my joints and legs in particular. Usually I am very sore from working all day, but I haven’t been feeling the pain as badly!
My digestion and gut health has also improved and that is having positive outcome on my mental state too.
