Is Your Nattokinase Supplement Effective?

How To Pick A Nattokinase Supplement That Works
- And Get It At A Great Price!

From fermented soybeans to supplement shelves, Nattokinase is having a moment. So we decided it was time to write an in-depth analysis of Nattokinase and what you want to look for when buying a supplement. Nattokinase, a powerful enzyme derived from natto, has gained attention for its potential role in supporting circulation and heart health.

With the growing interest in this ingredient, supplement manufacturers have been creating their versions of a Nattokinase product, with wild claims as to its actual benefits. As each new company bursts into the market, it becomes harder to separate fact from fiction, premium product from worthless imitation.

We decided it was time to analyze the products ourselves to find out which were subpar, which were flat-out lying about what was even in their pills, and which, if any, might actually be worth a try. First and foremost, we wanted to come up with specific criteria to establish what would make an effective supplement for supporting circulatory health with Nattokinase. Here's what we came up with.

It’s hard to believe, but most companies slap on a label that says ‘Nattokinase Supplement’, often without even mentioning how much Nattokinase is in each pill or with misleading information.

What Did We Research?

With hundreds of manufacturers out there, we wanted to figure out what to look for and how to overcome our concerns regarding supplements for cardiovascular support. We started the process by making a list of the main concerns we have over buying a Nattokinase product.

  • It’s not going to be effective. The truth is, there are a lot of products that don’t work at all. Typically, this is because they don’t contain the right ingredients or the right proportions. A lot of interested consumers don’t realize how exact of a science it is to create an effective supplement.
  • It’s going to be too expensive to afford. As we conducted our research, we found that some companies sell Nattokinase supplements for $100 or more! Who wants to risk that kind of money on what could just be snake oil salesmanship?
  • The company I buy from might just be exploiting another fad. How can you tell when a manufacturer is just trying to cash in on the latest health trend? Most of those companies are all gimmick and no substance. How do you know that the company you choose to buy from is giving you the real deal?

Finding High-Quality Nattokinase Supplements

So, how can you identify the legitimate products through all the smoke and mirrors? There are a few key factors to look for that can all but guarantee the product is genuine.

  1. Third-Party Monitoring: Independent monitoring companies track each company’s reputation and customer satisfaction. One of the most important qualities for a supplement manufacturer is their reputation. Look for a company with a solid reputation backed by third-party monitoring.
  2. Risk-Free Money-Back Guarantee: Go with a company that guarantees their product and offers your money back if you aren’t satisfied. If the company is not willing to put their money where their mouth is, that means they don’t believe in their own product.
  3. Third-Party Testing: Different from third party monitoring, third-party testing verifies the quality of each company’s products. Third-party testing is really expensive for manufacturers, since it can actually disqualify entire shipments of pills. But when companies don’t have independent quality control, there is no guarantee that their products are what they claim to be.

Our Research On Nattokinase Supplement Brands

Your time and money are valuable and we don’t want you to waste either one. So we did research on most of the top supplements available for supporting healthy blood flow with Nattokinase.

We studied each product to determine which consistently had not only the right ingredients, but also the right proportions. We disqualified the ones with unnecessary, synthetic fillers, and those whose contents differed drastically from pill to pill.

We didn’t stop there. After all, numbers and percentages are only part of the story. We went on to seek out real customers who had used the products we tested. We asked them for testimonials and compared them with our notes, and then compiled this information to give you a list of the best products on the market.

What Our Research Uncovered

A good Nattokinase supplement should contain a clinically effective daily dose of 2,000 FU (fibrinolytic units) per serving. It should be derived from non-GMO soybeans. Ideally, it should also contain BioPerine® or a similar thermogenic enhancer to improve absorption. There is no need for any additional unnecessary ingredients, binders, fillers, additives, or preservatives.

We found only one product that met this criteria. Our #1 product choice contains:

  • Active Nattokinase standardized to 4,000 FU.
  • Non-GMO, vegan-friendly formula, and free from common allergens (excluding soy).
  • 2 capsule dosage for maintaining effects throughout the day.
  • BioPerine® to enhance absorption and efficacy.
  • Free of Vitamin K2 to prevent an adverse interaction with anticoagulant medications.
  • No unnecessary ingredients, binders, fillers, additives, or preservatives.

Most products did not pass the above criteria.

Most manufacturers do not use 2,000 FU of active Nattokinase per capsule, allowing for up to 4000 FU per day. Many cut corners with low-quality or unstandardized products. Rarely do products include BioPerine® or similar ingredients to improve absorption. Other companies filled their supplements with cheap fillers and unnecessary additives. Almost all of them avoided quality control testing.

The brands we did pick, we stand by. We are confident that these products can help you achieve your goals and get the results you so desire.

#2 Pick

Klair Labs Nattokinase NSK-SD

Klair Labs Nattokinase NSK-SD Klaire Labs, now transitioning to the SFI Health brand, offers a Nattokinase supplement that delivers a solid dose of 4,000 FU per day using the clinically studied and patented NSK-SD®. This formula is split into two capsules for flexible dosing and has earned high customer ratings. While it meets many of the criteria we look for, including being GMP-certified and free from Vitamin K2, it lacks BioPerine® for enhanced absorption and only comes with a 30-day refund policy. Additionally, a past recall from the brand raises some concerns about product testing transparency.

Rating: OK

#3 Pick

Allergy Research Group Nattokinase

Allergy Research Group brings over four decades of industry experience to its Nattokinase supplement, which contains the well-researched NSK-SD® at a daily dose of 4,000 FU. It comes with a 60-day satisfaction guarantee and delivers a comparable dosage. However, it differs in several ways that could impact its value. The formula comes in softgels, introducing extra ingredients not typically found in capsules, and it lacks BioPerine® to aid absorption. While the company advertises the Nattokinase as vegan-derived, the product itself includes animal-derived ingredients and is not suitable for vegans. Despite some user-reported side effects, most reviews are positive, suggesting it works well for many people.
