  • The daily dosage is split into two capsules for sustained effects.
  • It does not contain Vitamin K2 which could cause interactions.

Effectiveness

We found Research Verified Nattokinase to be a highly effective supplement for supporting cardiovascular health. This appears to be due to its high-potency formula and premium-quality ingredients. It delivers a strong daily dose of 4,000 FU, split between two capsules, and includes BioPerine® to boost nutrient absorption. Importantly, it does not contain Vitamin K2, and therefore helps reduce the risk of interactions with anticoagulant medications.

We appreciate that this product gives users flexibility - recommending 1 to 2 capsules per day - so you can choose between a half or full dose. Additionally, by taking 2 capsules throughout the day, it provides steady effects and better absorption than a sudden massive intake. The 4,000 FU daily amount is higher than many other products but is still within the studied range. In a clinical study, participants who took 2,000 FU twice daily (4,000 FU total) saw a reduction in blood pressure. Still, a 2,000 FU dose can be effective for many users, which makes this adjustable dosing a smart feature.

Overall, the combination of a well-formulated product, positive customer reviews, and a transparent, responsive company helped Research Verified Nattokinase check all the right boxes:

  • Natural ingredients
  • Customer satisfaction and results
  • Customer service

Safety

Research Verified Nattokinase appears to be a safe supplement when taken as directed. The formula is made with natural ingredients and is free from unnecessary additives, artificial fillers, and binders. It is manufactured in a cGMP-certified facility and undergoes third-party testing for purity and quality, providing an extra layer of assurance. Notably, it does not contain Vitamin K2—an important consideration for individuals taking blood-thinning medications, as K2 may interfere with anticoagulants. The product also offers dosing flexibility (1 to 2 capsules daily), allowing users to tailor their intake based on individual needs or health conditions. However, individuals with soy allergies should exercise caution, as the label notes the product may contain soy - a reasonable possibility given that Nattokinase is derived from fermented soybeans. As with any supplement, consult a healthcare provider before use, especially for those with underlying medical conditions or who are taking prescription medications.

Price

Research Verified Nattokinase earned our #1 spot not only for its quality and effectiveness, but also for its excellent value. The pricing is straightforward and competitive, with multiple options based on how much you buy: a 1-month supply costs $48, a 3-month supply drops to $33 per bottle, and the best deal is a 6-month supply at just $24 per bottle. There’s no auto-ship program or hidden recurring charges so what you see is what you get. Considering that many lower-dose 2,000 FU supplements are sold at similar prices, Research Verified offers significantly more value for your money.

All orders are shipped out within 24 hours (except for those ordered on weekends and holidays). They are also sent in discreet packaging to protect your privacy. To top it off, this company offers an unprecedented 365-day risk free trial. If for whatever reason customers are not 100% satisfied, they can ship the bottles back for a refund at any point within a calendar year. Now, that’s a guarantee we can get behind!
