FAQs

Frequently asked

Can NAG help with leaky gut?

Yes, NAG provides the substrate for the intestinal mucus layer, which is vital for maintaining gut barrier integrity and can help address issues related to increased intestinal permeability.

Is NAG safe for people with shellfish allergies?

While NAG is often derived from shellfish, allergen-considerate forms are available. It's important to check the product label or consult with a healthcare provider if you have a shellfish allergy.

How long does it take to see results from NAG for joint pain?

Benefits for joint health are typically observed after consistent daily intake for 4 to 12 weeks, as it supports the gradual synthesis of cartilage components.
