Ingredient Quality
Horbaach was one of only two brands to pass SORA Labs testing among eight tested. It came in at 3,720 FU against a 4,000 FU claim — 93%, comfortably within an acceptable range for a delicate enzyme. While it didn't exceed its claim like NF, delivering 93% of stated potency puts it far ahead of the many brands that fail badly.
Value Analysis
Horbaach is priced below NF Supplements while still being independently verified, which makes it our best-value verified option. Note that it is no longer available to buy within the UK, so it must be imported — which adds cost and delivery time.
Effectiveness
At a verified 3,720 FU per capsule, Horbaach delivers a genuine, research-relevant nattokinase dose. The higher per-capsule potency means you may want to adjust your serving size depending on your target dose.
Who Is This Best For?
Buyers who want independently verified potency without paying the NF premium, and who are happy with slightly less batch-by-batch transparency.

Horbaach Nattokinase 4,000 FU FAQ
Did Horbaach pass independent testing?
Yes — SORA Labs measured Horbaach at 3,720 FU against its 4,000 FU claim (93%), within an acceptable range. It was one of only two brands to pass among the eight tested.
How does Horbaach compare to NF Supplements?
