Frequently Asked Questions

What is Protective Complex?
Protective Complex is a dietary supplement built on a short chain amino acid complex, delivered in a stable salt form in oral capsules. Each capsule provides 500 mcg.
Why the salt form?
Short chain amino acid complexes are fragile in stomach acid. Binding the complex as a salt improves its stability and its absorption when taken orally, which is why we use it instead of a plain free form.
How do I take it?
One capsule daily on an empty stomach, or as directed by your healthcare practitioner. Most people take it first thing in the morning.
Is it third-party tested?
Yes. Every batch is tested at Janoshik Labs to 99%+ purity. The current Certificate of Analysis is published under Practitioner Resources on this page.
Where is it made?
Protective Complex is manufactured in the United States in a cGMP and NSF certified facility.

Overview

Protective Complex, explained.

Protective Complex is a short chain amino acid complex delivered in oral capsules, with 500 mcg in every capsule.

It is bound in a stable salt form, which protects it through stomach acid and improves oral absorption compared with a plain free form, and it pairs with an absorption carrier so it reaches the digestive tract intact.

Protective Complex works with your body to support normal digestive function, joint and soft tissue comfort, and normal nitric oxide production.*
