The Happenstence Story

2022: The Name

Why Happenstence?

The name came from a moment of serendipity — a blend of "happenstance" and Cooper Stence. It captures the spirit of how this whole thing started: by chance, driven by curiosity, and built into something intentional.

The Mission

Supplements You Can Actually Understand

We're committed to high-quality, effective supplements rooted in nature and backed by research — pure ingredients, responsible sourcing, and the educational content to explain why each one matters. No vague labels or blends designed to obscure.

The Standard

Manufacturer-Level Transparency

We work exclusively with globally trusted manufacturers like Creapure® in Trostberg, Germany — who produces the purest Creatine on Earth. Our mushroom suppliers verify active compounds at the source: >20% Polysaccharides in Lion's Mane, beta-glucan content in Turkey Tail, and 99.9% purity in our creatine. You can see the lab reports yourself.

The Approach

Educational-First, Always

An informed customer is an empowered one. That's why we don't just sell supplements — we publish deep-dive content on our blog covering health trends, ingredient science, and lifestyle insights so you can make confident decisions about what goes into your body.

Radical Transparency, Start to Finish.

We publish the same documentation and testing our manufacturers use. Every ingredient listed and verified. No vague labels, no B.S.

Sourcing

Real Fruiting Body Extract

Our core mushroom products are built around real fruiting body extract. Every ingredient is selected for quality standards, with sourcing documentation reviewed before it goes into a formula.

Active Compounds

Verified for Active Compounds

Our manufacturers verify for active compounds — not just weight. Polysaccharide content, beta-glucan levels, and purity specs are documented in supplier COAs on our testing page.

Documentation

Manufacturer-Level COAs Available

We make the same Certificates of Analysis our manufacturers provide us available to you. Raw material identity, active compound verification, and finished product specs documented on our site.

Labeling

No Proprietary Blends

Proprietary blends let brands hide underdosed ingredients behind a single total weight. We list every ingredient individually with its amount, with the exception of our Mushroom Complex.

Our Commitment

Good for You. Good for the Planet.

Profits aren't everything. We believe in being good stewards of the planet — through every order, every refill, and every dollar we reinvest into the world.

3 Trees

Refill & Reforest

Every refill order funds the planting of 3 trees in Kenya's mangrove forests — the world's largest continuous mangrove ecosystem. Through our partnership with Earth Lungs & GoodAPI, reforestation is verified and tracked monthly.

What Our Customers Say

Frequently Asked Questions

Where are your products made?

It depends on the product. Our Creapure® Creatine is manufactured by AlzChem in Trostberg, Germany — the gold standard for pharmaceutical-grade creatine. Our Lion's Mane capsules are encapsulated in the USA using organic fruiting body extract sourced from verified growers using log culture.

How do I know your products are actually what you say they are?

We publish manufacturer-level COAs on our Lab Reports page — the same documentation our suppliers provide us. For mushroom extracts, supplier COAs confirm polysaccharide and beta-glucan content. For Creapure®, every container includes a QR code authentication seal you can scan yourself.

What's the story behind the name?

Happenstence is a combination of "happenstance" — meaning something that happens by chance — and Cooper's surname, Stence. The name reflects how the brand started: a serendipitous interest in functional supplements that grew into an obsession with quality and transparency. Read the full story on the blog.
