More Than a Vitamin Shop
Fullerton’s Natural Health Shop for Over 30 Years!
GMP Vitamins isn’t your average supplement store. Walk through our doors, and you’ll find something rare. A place where over three decades of expertise, genuine care, and deep passion for natural wellness all live under one roof. We carry vitamins, supplements, homeopathic remedies, sports nutrition, natural foods and teas, pet health products, and so much more. But what truly sets us apart has never been the products on our shelves. It’s the person behind the counter.
Meet Robert Kanter, ND
The Man Behind GMP Vitamins
Robert Kanter founded GMP Vitamins after noticing a problem in the health and wellness industry. Vitamin stores were everywhere, but genuine expertise was nowhere to be found. Customers were overwhelmed and misinformed, walking out with products that didn’t actually address their needs. Robert decided to do something about it.
Determined to give his customers real answers, Robert pursued extensive training in naturopathy and earned board certification as a Naturopathic Doctor. He built GMP Vitamins around a simple, but powerful idea. Every person who walks through the door deserves personalized, knowledgeable guidance, not a generic recommendation from someone reading the back of a label.
More than 30 years later, that mission hasn’t changed. Robert is still here, still learning, and genuinely invested in the health of every customer he sees.
What Makes Us Different
We’re Not Just a Store, We’re a Resource
Most vitamin shops sell products; we offer something more, a genuine health partnership. Here’s what you’ll find at GMP Vitamins that you won’t find anywhere else in Fullerton:
Live Cell Analysis
Robert specializes in Live Cell Analysis, a powerful wellness screening tool that examines a single drop of your blood under a high-powered microscope in real time. You’ll see exactly what’s happening in your body and leave with a personalized supplement plan tailored to you. Not a guess. Not a generic protocol. YOURS.
Diagnostic Testing On Site
We offer A1c (blood sugar testing) and cholesterol testing right here in the store. Fast, affordable, and without the wait of a doctor’s visit.
A Curated, Extensive Selection
From homeopathic remedies and essential oils to sports nutrition, natural foods, and pet supplements, we carry an incredibly diverse selection, all hand-chosen, with quality and efficacy in mind. If we don’t have it, ask us; special orders are always available.
Guidance You Can Trust
Every recommendation we make comes from genuine knowledge and genuine care. Whether you’re brand new to supplements or a longtime wellness enthusiast, we meet you where you are and help you find what actually works for you and your body.
Our Store
A Place Unlike Any Other
Step inside GMP Vitamins and you’ll immediately notice it doesn’t feel like a chain store. The walls are lined with framed artwork, anatomical charts, and decades of collected history. A massive homeopathic remedy cabinet holds hundreds of remedies. Robert’s microscope sits ready at his desk, waiting to inform you and Robert about your body’s needs and how we can serve you to get your body back into balance. It’s a store with soul. A place where regulars are greeted by name, questions are always welcome, and nobody leaves without an answer. Customers drive from across Orange County and further (Anaheim, Corona, Los Alamitos, Placentia) because what Robert offers can’t be found anywhere else.
