Best Nattokinase Supplements in Australia (2026)
, 6 min reading time
Our picks of the best nattokinase supplements in Australia for 2026, compared by FU strength, format, price per capsule and who each one suits.
Last reviewed: October 2026
There is no single best nattokinase supplement for everyone. The right choice depends on the FU strength you want, how much you want to spend per capsule, and whether you prefer a standalone product or a combination formula. Below are our picks from the range we sell, with current prices in AUD, so you can compare like with like. For a full list, see our nattokinase supplements Australia collection.
How We Chose These Nattokinase Supplements
These picks are based on information printed on each product label and on current price. We compared:
- FU strength per capsule. FU (fibrinolytic units) measures enzyme activity, so it is the number worth comparing, not milligrams.
- Price per capsule or softgel. Larger bottles often cost far less per serving.
- Format. Standard, delayed-release or enteric-coated capsule, vegan or not.
- Added ingredients. Standalone nattokinase versus formulas with vitamin K2, CoQ10 or serrapeptase.
Please note: we have not independently lab-tested these products, and we don't make third-party testing claims on the manufacturers' behalf. If testing or certification matters to you, check the product page and manufacturer's information. This article is general information, not medical advice.

Lowest Price to Start: Nutricost Nattokinase (30 Capsules)
At $19.84 for 30 capsules of 2,000 FU, Nutricost Nattokinase is the lowest-cost way to try a standard-strength standalone nattokinase. If you decide to continue, the 120-capsule bottle at $38.56 works out to roughly 32 cents a capsule, the lowest price per capsule in our 2,000 FU range.
Best Delayed-Release: Dr. Murray's Nattokinase
Dr. Murray's Nattokinase provides 2,000 FU in a delayed-release vegan capsule, starting at $22.51 for 30 capsules. It suits shoppers who specifically want a delayed-release format at a low entry price.
Best Known Standalone Brand: Doctor's Best Nattokinase
Doctor's Best Nattokinase is a standalone 2,000 FU vegan veggie capsule in 90 or 270 capsule packs, from $42.72. The label notes it is non-GMO and contains soy. It is a good fit if you recognise the brand and want nattokinase without added ingredients. Doctor's Best also makes a CoQ10 + Nattokinase formula.
Best Available at Woolworths: Eumundi Botanicals Nattokinase
If you want the same product you may have seen at Woolworths, Eumundi Botanicals Nattokinase Natural Soy Enzyme (2,000 FU, 60 capsules) is $39.95 here. See our retailer breakdown for what Woolworths, Chemist Warehouse, Priceline and Coles stock.
Best Higher Strength: Arthur Andrew Medical Nattovena (4,000 FU)
Nattovena provides 4,000 FU per vegan capsule and comes in 30, 90 and 180 capsule sizes, from $37.92. The label directions state a number of capsules per day, so check the pack size against the directions before you buy. Other 4,000 FU options include Source Naturals NSK-SD ($64.18, 30 vegan capsules). A higher FU number is not automatically better for everyone, so speak with your doctor or pharmacist first.
Best High-Strength Value: Micro Ingredients Enteric Coated Softgels
The Micro Ingredients 240 Enteric Coated Softgels provide 4,000 FU per softgel for $85.92, which works out to roughly 36 cents per softgel. It is the lowest price per serving of any 4,000 FU product in our range, as long as you are comfortable buying a large bottle.
Best With Vitamin K2: Swanson Vitamin K2 with Nattokinase
Swanson Vitamin K2 with Nattokinase combines 50 mcg of vitamin K2 (MK-7) with 100 mg nattokinase at 2,000 FU in a once-daily softgel, $43.95 for 30. The Vitacost Vitamin K2 MK-7 with Nattokinase is a K2-led formula (100 mcg K2 with 320 FU nattokinase) from $23.95. Read our guide to taking nattokinase with vitamin K2 before choosing.
Best With Serrapeptase: Doctor's Best Natto-Serra
Doctor's Best Natto-Serra pairs 2,000 FU nattokinase with 40,000 SPU serrapeptase in one daily delayed-release vegan capsule, 90 capsules for $75.95. For a higher-FU enteric-coated option, compare Solaray Nattokinase Serrapeptase (3,000 FU nattokinase and 60,000 units of serrapeptase, $72.66).
How to Choose a Nattokinase Supplement
- Check FU, not just milligrams. Our dosage and FU guide explains what each strength means.
- Compare price per capsule, not bottle price.
- Check allergens. Nattokinase comes from fermented soybeans, and many labels state that the product contains soy.
- Check warnings. Nattokinase has fibrinolytic activity. Talk to your doctor or pharmacist before using it if you take blood-thinning medication, have a bleeding disorder, are pregnant or breastfeeding, or have surgery planned.
- Check AUST L status on the product page if it matters to you, as not every imported product carries it.
Frequently Asked Questions
What is the best nattokinase supplement in Australia?
It depends on your priorities. Nutricost and Dr. Murray's are low-cost 2,000 FU options, Doctor's Best is a widely recognised standalone brand, and Nattovena is a 4,000 FU option. Compare FU, price per capsule, format and warnings against your own needs.
Which nattokinase strength is most common?
2,000 FU is the most common strength sold in Australia. Higher-strength products start at 4,000 FU.
Is there a 10,000 FU nattokinase in Australia?
We don't currently list one. The highest per-capsule strength in our range is 4,000 FU. Some products state potency per gram rather than per capsule, so read the label carefully.
Where can I buy nattokinase in Australia?
Online supplement retailers carry the widest range, and Woolworths stocks one dedicated product. See our full guide to where to buy nattokinase in Australia.
Is nattokinase safe to take with blood thinners?
Not without medical advice. Nattokinase has fibrinolytic activity, so combining it with anticoagulant or antiplatelet medication may increase bleeding risk. Speak with your doctor first.
