i take this product to help clear microclots from long COVID. i recommend this product as it's the only one here with NSK-SD graded ingredients, straight from Japan. don't risk it with dubious quality ones. great job, source naturals!

Seems to be working very well with complimentary supplement feeling the benefits after just a few days. Very happy with the brand for the price. Great.

I'm using this pills for healthy heart, but can't tell now about the effect, will add after check at my Doctor. But feeling better

Experiment at the beginning, but there are a lot of expectations. Blood vessels give thanks

Nattokinase works well in supporting the circulatory system and lowering blood pressure.

got this after learning nattokinase is a good supplement that can slow down aging... trusting source naturals brand so gettting this

Combined with another product I can have my blood flow better.

Not the best purity or does not fit me. After using got headache. Price is good.

Love the easy to take capsules.

What a good products. I always take it.
