TABLE OF CONTENTS
What is serrapeptase?
Serrapeptase, also known as serratiopeptidase or silkworm enzyme, is an enzyme derived from silkworms commonly used as a dietary supplement for improving digestion. This article is about the main benefits of serrapeptase, its potential side effects, the best time to take it, and more.
Possible benefits
All of the potential benefits mentioned below are dose-dependent. As with most other supplements, there is a sweet-spot dose that allows you to get most of the benefits without causing meaningful side effects or tolerance buildup in the body. We will discuss the best dosing protocol later in this article.
Minor benefits
Possible side effects
The side effects below are dose-dependent. The risk for them increases (often linearly but sometimes exponentially) as you increase the dose. Some of the side effects only apply to very high doses.
Who should not take serrapeptase?
You should probably avoid taking serrapeptase if you:
Who will benefit the most?

How much serrapeptase should you take?
The sweet spot dose typically ranges between 10-20 mg or 20,000-40,000 enzymatic units (sometimes labeled IU or SPU) daily for most people. This amount should provide most of the benefits without meaningful side effects.
The higher end of this range usually provides slightly more benefits in the short term. If you plan to take this supplement for a longer time (multiple months or years), the lower end is probably a better way to go since it is safer, and you would develop tolerance faster if you were to take higher doses.
The upper safety limit for this supplement is not well-established. To stay on the safe side, don’t take more than the recommended dose unless you have a great reason to do so. Higher amounts may cause problems if you take the supplement for a prolonged period.
Like most other supplements, it is best to cycle serrapeptase and take about two days off weekly to reset your tolerance. That will allow you to keep getting the benefits in the long term.
Best time to take serrapeptase
The best time to take serrapeptase for improving digestion is about 30 minutes before or 2 hours after eating a meal.
Serrapeptase is water-soluble, so you don’t have to take it with food to absorb it well.
Whether you take the supplement in the morning or the evening does not make much difference. Both options are fine so feel free to experiment.

Where to buy serrapeptase?
In most countries, Amazon is the best option for ordering serrapeptase supplements. They offer some very affordable products backed by many positive reviews. Also, you can choose from a wide range of brands without having to search through other markets on the Internet.
Some brands display the dosage per serving instead of per pill or capsule. Therefore, you may accidentally buy something less potent than you intended. Do not fall for this marketing trick.
