70 Years of Science: The Story Behind Every Shaklee Product

When you take a Shaklee supplement, you’re getting more than a bottle of vitamins — you’re benefiting from nearly 70 years of dedicated scientific research. Since Dr. Forrest C. Shaklee’s earliest work in nutritional science, the company has built its reputation on rigorous testing, real clinical research, and a refusal to cut corners.

A Legacy Rooted in Research

Shaklee was founded in 1956, but its scientific roots go back even further — to 1915, when Dr. Forrest Shaklee developed Vitalized Minerals, widely recognized as one of the first multivitamin products created in the United States. That early commitment to formulating supplements based on real nutritional science set the tone for everything that followed.

More Than 100 Clinical Studies

Today, Shaklee has published more than 135 scientific papers and presentations, including over 90 clinical studies in peer-reviewed journals — an unusually high bar for a supplement company. Shaklee reports more than 110 clinical studies overall, backed by over 70 patents and patents pending and a research investment measured in the hundreds of millions of dollars.

Testing That Goes Beyond What’s Required

Every batch of Shaklee product undergoes rigorous quality testing — more than 100,000 tests each year — to verify purity and potency before it ever reaches a customer’s home. Formulas are held to standards stricter than what the law requires, a philosophy that has remained constant since the company’s earliest days.

Why It Matters to Us

At Spano Health & Wellness, we don’t just sell supplements — we stand behind the science that goes into them. When we recommend a product, it’s because we trust the research, the testing, and the decades of consistency behind the Shaklee name. That’s the “Real Science” in Real Science. Real Results. Real Life — and it’s the foundation everything else we do is built on.
