I like that the product is made in USA, hence more trustworthy than the Chine made products. Since I started taking this supplement my BP has gone down from 135/110 (with medication) to 112/78 (still on the same medication). This is my personal experience only, so take it with a grain of salt :)

Seems good so far

I have been taking nattokinase for years and decided to give this a try, I have to say that this is the only one that have a plastic chemical aftertaste and smell right out of the container that makes me gag each time. Still give it a go but the aftertaste and chemical burp after despite how much water I take is a huge turn off. I also find my tummy hurting every time so not sure what's up with this product.
I know it is high mg but don't see the health benefits like my other ones. My previous one I can see the difference on inflammation the next day but this one is not.
Value wise I don't think it is worth it.
Not for me!

Lunakai USA Made Nattokinase Supplement-I eat natto, but this is a nice way to get heart and circulation support without having to eat a good amount of natto. Nattokinase is a specific enzyme created when fermenting/making natto. The capsules are easy to swallow with no aftertaste or smell, an you don't have to take it with meals. You get 60 in a bottle, so a month's worth. I like that it's 3rd party tested and manufactured in the US. The only other extra ingredients are white rice flour and hypromellose for the capsule. If you are allergic to soybeans, you shouldn't take this. I had no side effects and quite happy with this supplement.

I've been using the Lunakai Nattokinase Supplement for a few weeks, and I'm really happy with the results! Each 400mg capsule packs an impressive 4000 FU, delivering robust support for heart health and circulation. I feel more energized and notice improved blood flow during my daily activities. The fact that it's USA-made, non-GMO, and comes in a convenient 60-count bottle is a huge plus. The capsules are easy to swallow with no aftertaste. Highly recommend this high-quality supplement for anyone looking to boost their cardiovascular wellness! A good buy for the money.
