"I built Vetta Bio because I was tired of recommending supplements I couldn't fully stand behind. Every formula we make starts with the question: would I give this to my own clients?"

Andrew's Philosophy
Most of the supplement industry operates on marketing logic, not clinical logic. Products are formulated to look impressive on a label — not to deliver measurable outcomes for real people.
Andrew's approach is different. Every recommendation — whether in a private consultation or in a Vetta Bio formula — starts with the peer-reviewed literature. If the evidence doesn't support a claim, the claim doesn't get made.
Peer-reviewed research over industry marketing
Clinically relevant doses, not label-dressing amounts
Transparent sourcing and third-party testing
Protocols built for real schedules, not ideal conditions
Honest about what supplements can and cannot do
The Vetta Bio Mission
A supplement brand built by a practitioner, for practitioners and the professionals they serve.
Evidence First
Every recommendation Andrew makes is grounded in peer-reviewed research. If the evidence doesn't support it, he won't recommend it — regardless of trends or commercial pressure.
Built for Real Life
Protocols designed for people with demanding schedules, not athletes with unlimited time and resources. Practical, sustainable, and realistic.
Honest Guidance
Andrew will only recommend products — including his own — where there is a genuine clinical rationale. No upselling. No conflicts of interest dressed up as advice.
Whole-System Thinking
Supplements are one tool. Andrew looks at sleep, stress, nutrition, movement, and gut health as an integrated system — because optimising one lever in isolation rarely works.
Work with Andrew
Whether you want a personalised protocol or simply want to start with the product Andrew formulated for professionals like you.
