Meet the founder

Formulated by a biochemist

Holly Williamson, Founder, lead Chemist and Molecular Biologist.

STMNA Bioactives founder and formulator is an expert in biochemistry. She carefully chose six potent plant extracts each with bioactive compounds that are clinically proven to improve daily health as well as healthy ageing.

Each ingredient works in synergy, meaning that they work better together compared to the individual bioactive. The formula also has naturally enhanced bioavailability. This means you absorb the compounds much more easily, so you get their full health benefit.

Plant extract:

Curcuma longa rhizome (Turmeric) extract

bioactive compound:


dosage (IN 2 CAPSULES):

210 mg of extract

Equivalent to 200 mg of curcumin

Curcumin has been used traditionally for thousands of years in Ayurvedic medicine to treat inflammation, digestion and liver concerns. Scientific research in the 70’s revealed that curcumin had a number a therapeutic potentials. However, it was still not commercialised due to low bioavailability.

Current clinical studies focus on naturally improving bioavailability so that the benefits are much more potent. It has been shown in scientific research to have the benefits below and more.

Boswellia serrata

Plant extract:

Boswellia serrata (gum resin) extract

bioactive compound:

Boswellic Acids


400 mg of extract

Equivalent to 260 mg of Boswellic acids

Boswellia serrata is otherwise known as Frankincense and has been used traditionally as an incense. It has also many traditional ayurvedic uses to treat inflammatory conditions.

Research has shown that Boswellia works in synergy with curcumin to reduce pain and inflammation better than if they were taken alone.

Plant extract:

Vitis vinifera (grape seed) extract

bioactive compound:


Dosage (in 2 capsules):

100 mg of extract

Equivalent to 80 mg of procyanidins

Grape seed extract contains bioactive compounds called procyanidins. These polyphenol molecules are responsible for the purple colour in grapes. They have potent antioxidant activity.

Procyanidins support collagen production as they are a linker for the collagen molecule! This aids in improving skin, hair and nail quality – giving you that young glow!

Plant extract:

Withania somnifera root (ashwagandha) extract

bioactive compound:



200 mg of extract

Equivalent to 10 mg of withanolides

Ashwagandha has been used for thousands of years in traditional Ayurvedic medicine to treat stress and improve sleep quality.

Modern science has revealed that the active compounds in ashwagandha are called withanolides and are considered adaptogens. They protect the body from outside stressors such as environmental, emotional or physical stress.

Plant extract:

Reynoutria japonica root (resveratrol) extract

bioactive compound:


dosage (in 2 capsules):

200 mg of extract

Equivalent to 196 mg of Resveratrol (trans)

Resveratrol is a well-known molecule found in the skin of red wine grapes. It is famous as it was found in mice models to reverse the signs of ageing. Human clinical trials have not been able to prove this theory yet.

However, this polyphenol molecule is an antioxidant and therefore has scientifically proven health benefits.

Resveratrol usually has poor bioavailability, but when combined with piperine and grapeseed, it naturally increases the absorption substantially.

Plant extract:

Piper nigrum (black pepper) extract

bioactive compound:



10 mg of extract

Equivalent to 9.5 mg of piperine

Black pepper has been used traditionally in Indian cooking whenever combined with turmeric to help with absorption. It is also used in Ayurvedic medicine.

Piperine has been shown in scientific studies to improve the abroption of curcumin and resveratrol. It does this by inhibiting an enzyme that metabolises those molecules into inactive compounds.
