Serra RX80

(35 customer reviews)



Science & Research / FAQ-Frequently Asked Questions

Serra RX80®(serrapeptase) is a powerful systemic enzyme that supports the body’s response to inflammation and the respiratory and sinus systems. Providing 80,000 SU (serrapeptase units) of activity per capsule, Serra RX80 is unrivaled among products of its kind.

Serrapeptase – also known by serrapeptidase, serratiopeptidase and serratia peptidase – is a powerful proteolytic enzyme derived from a species of bacteria originally found in the intestine of silkworms. The bacterium, Serratia mercesans, produces the enzyme serrapeptase to enable the silkworm to dissolve its silken cocoon and emerge after metamorphosis. Don’t worry – no worms were harmed in the making of Serra RX80. Serratia is now grown in cultures to produce serrapeptase by fermentation.

Serra RX80 supports our body’s systems with the bio-energetic charge of enzymes to help them operate optimally, and address issues such as inflammation, excessive mucus in the respiratory and sinus systems and fibrin build-up.*

Serrapeptase has the unique ability to digest non-living tissue that is a by-product of the healing response without harming living tissue. Fibrin is a tough protein arranged in long fibrous chains. It is formed from fibrinogen, a soluble protein produced by the liver and found in blood plasma. Fibrin tends to form circulating complexes that create barriers against the absorption of healing nutrients in and around areas of inflammation.*

Numerous research and clinical studies have demonstrated serrapeptase has anti-inflammatory, proteolytic (protein dissolving) and fibrinolytic (fibrin dissolving) properties. This unique activity of Serra RX80’s enteric-coated serrapeptase supports normal fibrin metabolism, blood viscosity and blood flow. Serrapeptase supports healthy inflammatory response by reducing metabolic inflammation, usually an asymptomatic inflammatory process in response to stress, improper nutrition and other environmental issues. In addition, there is evidence of inhibition of C-reactive protein, a marker of inflammation that has been linked to cardiovascular health.*

How do SU’s relate to IU’s?

Enzyme activity is often measured through a FCC (Food Chemicals Codex) or USP (United States Pharmacopeia) assays and is denoted by IU, or international unit. Some enzymes don’t have a standard FCC or USP assay, such as serrapeptase. However, Japanese Pharmacopeia (JP) has established an activity assay specific for serrapeptase, which measures activity in SU, or serrapeptase unit.

You may see IU or SU used interchangeably on different serrapeptase products. While we do not know what sort of assays other companies use to test their enzymes, you can still compare the activity level on a one-to-one basis. So 80,000 IU is 80,000 SU, but SU is specific to serrapeptase.

Unlike other supplements, the weight (mg) of an enzyme supplement carries no significance. It is not the amount but the potency, or activity, of the enzyme that really matters. Guaranteeing the ingredients are available to the body is more important than how much of the ingredient is listed on a supplement label.

  1. If I could hug you through my computer I would!

    Diane C.

    I have been using Serra RX and Serracor NK for several months. I have had severe eye swelling due to lymph removal in my neck. I was diagnosed with Lymphedema. I have been through Hodgkins Disease and Breast cancer. I have been to countless doctors and none of them knew what to do. I have spent hundreds of dollars trying everything that claimed to help. Nothing worked. I was researching on-line and stumbled upon your website I called and asked a lot of questions. I thought why not give it a try I’ve already spent a ton of money. After 4 weeks I started to notice the swelling was less. After 2 months it is so small that my friends and family can’t notice it anymore. The pain and swelling are nearly gone. I have literally cried with relief. I did a lot of research about the product and I have found nothing but positive responses. If I could hug you through my computer I would. I swear this is the truth. Please try these products. I know people say this but truthfully this is the first product review I have ever written. I intend to use these products forever.

  2. Excellent products!

    Robert B

    Excellent products! After 24 months of using Serracor-NK and Serra Rx my IPF has remained stable!! My respiratory specialist thinks I should have been dead about 21 months ago, he’s a bit upset.

    Have also started using Prostate Rx 14 which has reduced my PSA reading from 12.25 to 9.49 in 3 months

  3. I've regained my stability


    I was diagonised with extramural fibroids in 2006 , I’ve been having pressure in my body that was giving me headache especially if I wear a trousers or skirt that is tight on my waist , I was really feeling uncomfortable , weak and unstable, was having blotted stomach. I started taking Serracor-NK and Serra RX now 6 weeks , I’m feeling strong, the pressure has gone I can wear tight trousers, I can exercise, I’m feeling stable and strong, my last month period was very heavy with big clots. I’m going to have a MRI scan next week I hope the size will be reduced.

  4. I feel like a new man

    Paul S

    I had a lot pain, due to a lot of scar tissue from four back surgies. I’ve been taking Serracor-NK and Serra RX for a month now and have had great results. I feel like a new man. Thank you Bio medic Labs!

  5. Wonderful Products!!


    I have been taking Serracor-NK & Serra RX 80 now since May 23, 2014. I have had years of pain throughout my body since a hit on the head with a steel bar at the gym.

    Nothing and I mean nothing has helped me, massage, chiropractic, cranial sacral, etc. You name it, I have tried everything and at a tremendous expense as you know insurance does not pay for these type of therapies.

    The above two products have helped me so much with the pain throughout my body and my lungs have become more clear.

    I would definitely tell anyone with pain to try it and be faithful in taking the high doses for 2-3 months. I plan to continue another month and then go on to the maintenance dosage..

  6. Tendonitis

    Pat Micallef

    I am writing in regards to your products, Serracor-NK and Serra RX 80. I have been taking both products faithfully for about two months now and would like to tell you the changes I have noticed.

    I worked at Ford Motor Company for 31 years and developed a bad case of Tendonitis in my right arm. Ford send me for therapy on many occasions with no relief. I have been retired now for 10 years with the tendonitis flaring up throughout those years.

    This past winter, I noticed it getting worse plus moving to my wrist and shoulder. I felt I was eventually going to lose use of my arm. The pain and movement of my arm was terrible.

    On June 1, 2014, I started taking these two products and hoped for the best. I want you to know that within the last two weeks, I have noticed that the pain is gone and I am getting the mobility back in my arm. I couldn’t believe this has happened after all the years in pain.
    Another bonus to go with this is the general well-being.

    Thank you for these wonderful products.



    I purchased SERRA RX80 & SERRACOR for circulation problems. After taking these for 2 weeks, my migraine headaches started to become less frequent and less severe. After 2 months, I was down to 1 headache/month. I tried twice to stop taking product due to expense, but the headaches were back within 2 weeks of stopping. I Have been on it over a year and haven’t had a headache in months. I took 6 of each capsule for 2months, then leveled off at 3 each/day. This stuff fixed what two medical doctors couldn’t help.

  8. Amazing Results!

    Sabrina S.

    I have had amazing results combining dietary changes and serracor/serrarx and dimpro rx. I have seen a 5 inch reduction in very large uterine fibroids. These products are amazing for both fibroids and inflammation.

  9. Good results


    I am experiencing some good results with this product. My periods have gotten lighter. Because I have fibroids, and have only been on this product for a few weeks, I am expecting I will see and feel some actual shrinkage of my fibroids.

  10. Only product that helped my husband.

    Joanne Lee

    This product helps my husband to be able to breath better and cuts down on his coughing. We’ve had wonderful results with it.
