2026's Top 5 Nattokinase Supplements

We picked Luma Nutrition’s Nattokinase supplement for our top spot because it’s the only supplement that meets our strict criteria.

Luma Nutrition uses a powerful dose of pure Nattokinase. It contains 4,000 FU per serving. Double the dosage of most other products.

Also, Luma Nutrition has a few different special offers available that give customers a big discount.

Finally, they offer a fair, 90-day, risk-free, money-back guarantee. Most companies won’t do this, which shows how much they stand behind their products. Overall, Luma Nutrition is our top pick.

Number two on our list is NSK-SD by Allergy Research Group.

This is a well regarded brand, but the biggest problem is that it only contains 2,000 FU of nattokinase per serving.

The price is also quite high. Definitely a more expensive option.

Overall, NSK-SD by Allergy Research Group does use great ingredients, but falls short on the effective dose to the other products on this list.

Number three on our list is XYMOGEN Nattokinase.

Again, this is another brand with a very good reputation for quality. The issue with this product is that the dosage is a bit lower at only 2,000 FU per serving. They make it confusing on the label to make it seem like it contains 20,000 FU.

This one was also the more expensive products we analyzed.

Overall, XYMOGEN Nattokinase is not too bad, and could be an option if you are willing to spend top dollar. But it falls short when compared to other products on the list.

Number four on our list is Pure Encapsulations Nattokinase.

While this brand does have a good reputation, the biggest problem is that the supplement only contains 2,000 FU of nattokinase per serving. And they charge a very high price.

In summary, Pure Encapsulations Nattokinase does use quality ingredients, but it ranks lower because of the less potent dosage and high price.

Number five on our list is Nattokinase Plus by DAVINCI Labs.

This product is priced very high for only having 2,500 FU of nattokinase per serving,but it does appear to be good quality ingredients.

In conclusion, Nattokinase Plus by DAVINCI Labs is a good choice based on quality, but we have to rank it lower based on the high price and lower dosage.
