Plant-based bioactives that are scientifically proven to optimise your daily health and to prolong your healthspan.

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.

prolong your 'healthspan'

Why choose STMNA Bioactives?

STMNA [stamina] bioactive formulations are natural plant-extracts, fully backed by scientific evidence to support daily health as well as healthy ageing. They unlock your body’s full potential – to be healthier for longer or improving your “healthspan”.

what is healthspan?

Healthspan is a term used to describe the period of a person’s life during which they are generally healthy and free from significant illness or chronic disease.

Due to many factors such as lifestyle choices, environmental factors, chronic stress, mental health and sedentary lifestyle, the average ‘healthspan’ is rapidly declining.

While anti-aging and increasing lifespan are popular topics, we believe that increasing the time you are healthy for is the key to wellbeing.

What if we told you there was a simple step you can take today to put your health first and increase your healthspan?

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”.

I feel calmer now, I have been taking them for a year now and can’t see my routine without them. They have definitely helped regulate my nervous system 🙂

Longer lasting energy

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.

I am feeling more alert and have more energy which is great. Great idea and environmentally friendly to have the refill pouches as opposed to bottles each time you order.

Like everything, it takes time and consistency to see compounding results. The support from Holly over the last 2 years has been undoubtedly the most helpful.

I felt the difference in the first two weeks. Sleep was so much better, no fog brain at 3 in the afternoon and helped me keep a decent weight. With these I am now able to control my stressful times much better. Thanks STMNA and Holly 🙂
