Absorption matters
It’s not just what you take. It’s what your body can actually use.
We select ingredients in forms supported by human research and designed for bioavailability. That means:
Standardised botanical extracts
Bioavailable nutrient forms
Fat-soluble nutrients paired appropriately
Doses aligned with research
Because a supplement only works if it’s absorbed.
Independent testing
Every batch is independently tested for purity, safety, and consistency — including heavy metals and microbiological screening.
The details matter.
Curious about what goes into your supplements? Here's a little more about our ingredients, formulations and commitment to quality.
We believe great supplements start with great ingredients. Every formula is thoughtfully developed with carefully selected ingredients, purposeful doses and quality at its core.
No unnecessary complexity. Just supplements designed to make your daily wellness routine simpler and more enjoyable.
Science plays an important role in how we develop our products. We look at nutritional research when selecting ingredients, choosing their forms and deciding how much to include.
Our goal is to create considered formulations, rather than simply following the latest wellness trends.
Our supplements are manufactured by trusted partners in the UK and Europe, with a focus on quality, safety and consistency.
We carefully select our manufacturing partners to help ensure every product meets our standards.
Yes. Independent laboratory testing forms part of our approach to quality assurance, helping us check that our products meet the relevant specifications.
We believe you should feel confident about what you're putting into your body.
Not all forms of an ingredient are the same. Factors such as how a nutrient is delivered, its chemical form and how it's processed can influence how the body uses it.
That's why we consider more than just the amount listed on the label when developing our formulas.
Every ingredient needs a purpose.
We consider the available research, ingredient quality, dosage and how different ingredients work together when developing our supplements.
Our philosophy is simple: include what matters, leave out what doesn't.

Certificates and awards
Our gummies include a high-quality Lion’s Mane fruiting-body extract, chosen for its concentration of naturally occurring beta-glucans and active compounds. Every extract batch is verified in an independent German laboratory to confirm purity and consistency before it ever reaches our formulation. By incorporating a meaningful amount of Lion’s Mane into each serving (700mg), we bring one of nature’s most researched functional mushrooms into your daily routine: clean, tested, and expertly crafted.
High-quality Cordyceps sinensis extract, valued for its naturally occurring cordycepin and polysaccharides. Sourced from controlled fermentation rather than wild harvesting, it offers consistency, purity, and a significantly lower environmental impact. Each batch is independently tested to verify identity and screen for impurities, ensuring a clean and reliable extract every time. By incorporating a meaningful amount of Cordyceps into our formulation, we bring one of the most studied functional fungi into your daily routine—steady, potent, and professionally crafted.
Our formulation features a carefully sourced Chaga fruiting-body extract, valued for its exceptionally high antioxidant content and naturally occurring beta-glucans. Every batch undergoes independent laboratory testing in Germany to confirm quality, purity, and consistency before it enters production. Delivered at a functional 700mg per serving, Chaga brings long-term, everyday support — not quick fixes — into your routine.
We use a premium Reishi fruiting-body extract, chosen for its concentration of beta-glucans and bioactive compounds traditionally associated with balance and resilience. As with all our extracts, each batch is independently verified by a German laboratory to ensure purity and consistency before formulation. Included at 700mg per daily serving, Reishi supports calm, steady foundations — the kind you build habits on.
KSM-66 Ashwagandha, one of the most clinically researched Ashwagandha extracts available and renowned for its high concentration of root-only withanolides. Produced through a specialised extraction process that preserves the plant’s natural profile, KSM-66 is backed by numerous human studies exploring its effects on sleep, performance, and overall balance. Every batch is independently tested to confirm purity and standardisation, ensuring we’re using a consistently verified ingredient. By including a meaningful amount of KSM-66 in our formulation, we bring a globally respected botanical into your daily routine with precision and integrity.
Plant-based source of Omega-3 DHA and EPA, derived directly from sustainably cultivated algae rather than fish. Algae is the original source of marine Omega-3s, allowing us to deliver these essential fatty acids in their pure form without ocean contaminants or environmental impact. Each batch of algae oil is rigorously tested for purity, stability, and oxidation markers to ensure clean, consistent quality. By incorporating a meaningful amount of DHA and EPA into our formulation, we bring a highly bioavailable, vegan-friendly Omega-3 source into your daily routine - cleaner for you, and cleaner for the planet.
ur gummies also include a thoughtfully balanced blend of essential vitamins and minerals: Vitamin B5, Vitamin B6, Vitamin B12, Zinc, and Vitamin D3.
