Serretia works

Good stuff!



A proteolytic (protein digesting) enzyme with potent fibrinolytic activity. It has been shown to support healthy sinus activity and promote a normal inflammatory response to overexertion.

Serrapeptase was discovered as scientists were studying silkworms and their ability to break down silk cocoons. They found that the silkworm excreted an enzyme that was responsible for breaking down the silk. As they looked further into the enzyme, they found a specific type of bacteria within the silkworm that was producing the enzyme, now referred to as Serratia E-15.

Serratia E-15 is used during the manufacturing process of serrapeptase today. Silkworms are not used in the production of serrapeptase, they were simply how the enzyme was discovered.

What is Serretia?

Serretia is comprised solely of serratiopeptidase, more commonly known as serrapeptase. Serrapeptase is a proteolytic enzyme originally discovered in the intestine of silkworms and is produced through the isolation of the microorganism Serratia E-15.

How does Serretia work?

Taken on an empty stomach, serrapeptase (a fibrin digesting enzyme) enters the bloodstream via the small intestine. Serrapeptase triggers fibrinolytic activity within the body. Its inherent ability to digest proteins enables the enzyme to support normal sinus activity as well as a normal inflammatory response to overexertion.

Why should I take Serretia?

Serretia helps to speed recovery after sports injuries, surgeries, muscle tears and pulls, as well as promote healthy sinus activity.

Can I take too much of serrapeptase?

Although Serretia contains highly potent serrapeptase, it can be safely incorporated into your supplement regimen. There have been no serious adverse events reported from the use of Serretia. However, it is important to follow dosage instructions unless otherwise directed by your healthcare provider.

Is Serretia enteric coated?

Enteric coatings are designed to protect enzymes and other supplements from stomach acid. Plastic-like chemicals known as phthalates are often used in this coating process. Phthalates are actually banned in children's toys in Europe and Mexico, so why would we ever include these in our formulas?

Arthur Andrew Medical has instead developed an all-natural, chemical-free acid armor capsule. These capsules are comprised of an extra-thick layer of cellulose (vegetable capsules) with a micro-threaded locking mechanism to prevent leaking. Acid Armor capsules have been designed to delay the release of the capsule's contents for up to an hour, without the use of potentially harmful chemicals.

When is the best time to take Serretia?

For best results, take the product at least one hour prior to eating and/or two hours after a meal.

Can I take Serretia with other supplements? Serretia can be used safely with other dietary supplements. In fact, we recommended taking it in conjunction with NEPRINOL or SYNTOL for additional fibrinolytic and probiotic support.

How long does it take for Serretia to work?

Although every person is different, some have reported feeling the effects of systemic enzymes in as little as 45 minutes. For therapeutic regimens, the progression may be slow for some and quicker for others. Serrapeptase has been clinically shown to thin mucosal secretions and limit pain due to injury. Those effects are typically noticed within days, however other benefits of taking Serretia on a regular basis will progress over time.

Is Serretia Kosher?

The formula is Kosher, and a copy of the certification is available by request.

Is Serretia vegetarian or vegan?

The formula is vegetarian in accordance with the guidelines of the AMERICAN VEGETARIAN ASSOCIATION.
