Product Overview


  • Dietary Supplement
  • Hypoallergenic

Altered intestinal microbial flora can occur alone, but it is often just one component of less than optimal gastrointestinal health, which can also include malabsorption and increased gut permeability. In the latter, molecules that would otherwise be too large to cross the gut mucosa are absorbed into the bloodstream, which can result in food allergies, autoimmune processes, and other systemic symptoms.

Perma-Clear provides nutrients and botanicals that nourish the intestinal tract and promote normal gut permeability. Glutamine nourishes and soothes intestinal mucosal cells, N-acetylglucosamine promotes a normal mucus layer in the gut and the growth of desirable Bifidobacterium bifidum; ginger provides antioxidant activity; and quercetin dampens histamine release. Lactobacillus sporogenes promotes beneficial gut flora and Saccharomyces boulardii stimulates immune health in the gut.

Suggested Use

Take 3 capsules two times daily or as recommended by your health-care practitioner.

Hypromellose (derived from cellulose) capsule, silicon dioxide.

Contains ingredient derived from shellfish (crab and/or shrimp).

High quality gut health product but the price has increased almost 30% since I last bought. I can find better in another product.

This is an excellent product. I feel that it is soothing if my gut is not feeling so good. It helps to keep me regular. I have been taking it for a year or so and feel overall my digestion is better and more immunity from tummy bugs

After a ten day course of three different types of antibiotics, I suffered symptoms from a permeable gut, such as cold/ flu symptoms , fatigue and crushing headaches. After a couple of days of permaclear (as recommended by my nutritional GP.) , my symptoms started to clear. I'm now two weeks into permaclear and I'm recovering to full health for the first time in six months.😊
