An antioxidant supplement designed to support bone health at the cellular level.
A pure, single-molecule antioxidant for everyday immune support.
Daily face care that targets harmful skin bacteria while preserving healthy skin flora.
Oral microbiome support spray — a simple add-on to daily brushing and flossing.

Dual-action sanitizer: kills on contact, then leaves an invisible protective coating.
Frankly, the many and varied health benefits documented for protocatechuic acid (PCA) reported in the literature and discovered in our studies are unbelievable. That would be so except for the fact they have been proven true by multiple credible publications and independent laboratory evidence.
Dr. Lanny does not do this for fame or money.
He developed this for the benefits it can have for others. For the first time in years, I sleep on both shoulders. I am no longer dependent upon OTC pain medicine. Remarkable product!

Since 2000, I’ve studied PCA, a unique reagent that not only reduces inflammation but also boosts joint health—so unique, it was patented, meaning there’s nothing else like it.

Yes, as a method for treating or reducing the severity of a joint injury or disease. Abundant evidence supported the various claims showing its effect to have prophylactic and therapeutic on surgically created arthritis in the experimental animal. US patent # 11,980,635 B.
Yes, in many health and wellness roles, but especially in joint health as determined by human and animal studies.
Yes. The FDA has ruled it is generally recognized as safe.
PCA will have the most benefit for early-stage injury or disease but not end stage bone on bone conditions.
As early as a few days with decease in swelling or inflammation. It may be as long as 4-6 weeks for some conditions. It is not usually helpful in end stage bone on bone joint changes.
You will not readily perceive PCA helped the cartilage. This is a silent benefit appreciated over time with good joint function.
PCA has dual action of decreasing the body’s anti-inflammation function plus increasing the integrity of the articular cartilage structure not found in other food supplements or over the counter medicines.
No injections. No prescriptions.
Daily treatments. More active as soon as a few weeks.
