Product Overview

  • Dietary Supplement
  • Pharmaceutical Grade
  • Non-GMO
  • Vegan
  • Kosher- Star K
  • GRAS- Generally Recognized As Safe

Neprinol Supports:

  • Normal Inflammatory Response
  • Normal Immune Function
  • Enhanced Blood Cleansing
  • Normal Blood Viscosity
  • Optimal Circulatory Health
  • Healthy CrP and Fibrin Levels

Neprinol is a proprietary combination of systematic enzymes including serrapeptase, nattokinase, bromelain, papain, and lipase. These enzymes were specifically formulated to support a healthy inflammatory response and defend the body from the damaging effects of fibrin. As fibrin accumulates within the bloodstream, it may impair circulatory health and amplify blood viscosity. Neprinol can help maintain normal fibrin, blood viscosity and joint health.

Suggested Use

Take Neprinol with 8 oz of water on an empty stomach, or as directed by your healthcare practitioner. Larger amounts may be divided into 2 or 3 servings per day.

Maintenance: 2-3 Capsules per day

Increased Support: 4-6 Capsules per day.

Therapeutic: 9 Capsules per day.

Other Ingredients

Cellulose (acid armor capsules)

Neprinol is free of dairy, gluten, and soy allergens. Contains no artificial colors or preservatives.

Neprinol utilizes phthalate-free Acid Armor capsules which have enteric properties that protect the enzymes from stomach acid without the use of chemicals and plastics commonly found in traditional enteric coatings.

Love this product. First ordered and used it for 6 months while deployed in Iraq. It help remove scar tissue, boosted my immunity, and made my body feel better, as in no physical issues, pains, etc. after constant patrols, fighting, etc. I recommend this product to all having fibrin issues. After literally 6 months use and only at 4 pills per day, it cleared up scar tissue issues that had built up within my body.

Expensive but well-formulated

Posted by Reviewer1236145 on Aug 14, 2010

Using this as part of a successful heavy-metal removal protocol. I have some VitalzymeSEB on hand but this seems more potent. I've found that taking equal amounts of each product to be quite effective. Oddly, I've noticed that taking 40% Neprinol and 60% VitalzymeSEB to be far less effective than a 50/50 split. Perhaps the body is ultra-sensitive to the final ratios of the underlying components (note that both products have similar ingredients). Both products are helpful for runaway middle ear inflammation (search for web article by Dr. James Howenstine).

After taking 9 tables 3x day on empty tummy for 3 weeks, i have not noticed any difference. Maybe fibrin was not the cause of a few things I wanted to resolve. Thank you

Neprinol AFD

Posted by Reviewer2228001 on Jun 29, 2011

Neprinol AFD has made a huge difference for us. We feel more energetic over all; digestion has improved also. Your prices for Neprinol are the lowest we have seen.

powerful and effective

Posted by 4815945088390607511 on Aug 10, 2014

After taking 10 caps a day to help heal an injury, I noticed that some 20 year old scar tissue under the skin in a different part of my body disappeared. I've been taking 4 caps a day every day for over a year. It's hard to quantify but I feel stronger and far less sore after gym workouts. |After my own experience and much research, I consider this well worth the price and one of my most important supplements.
