Is Flow Nattokinase worth it?

It depends on whether you want a high-dose nattokinase powder with added K2. At $59.99 for 30 days, it costs more than many capsule products, so compare the FU per dollar against capsule options.

How does it compare with nattokinase capsules?

The powder delivers 10,800 FU per serving with 180 mcg K2, which is on the high end. Capsules are easier to dose on the go, but this formula is soy free and vegan, which some capsules are not.

How much nattokinase do I get per serving?

Each serving provides 10,800 FU of nattokinase activity, plus 180 mcg of vitamin K2 as MK-7. The tub is a 30-day supply.

Does it contain soy or caffeine?

No. It is soy free and caffeine-free, and it is also non-GMO and vegan.

What does it taste like and how do I take it?

It is a chocolate-flavored powder, so it can be mixed into water or a smoothie. Follow the serving size on the label rather than guessing.
