Nattokinase+ is built the way a dietitian would: real ingredients, at real doses, chosen for how they work together. Curcumin is notoriously poorly absorbed on its own, which is why it's paired with bromelain, which potentially aids absorption, and piperine, well known for enhancing bioavailability.

Nattokinase is a fibrinolytic enzyme that may help support healthy circulation. Bromelain and curcumin together may also support the body's inflammatory pathways. Vitamin C and zinc contribute to normal immune function, alongside black seed extract, a traditional botanical in the formula.

Take 1 capsule daily with water, ideally between meals and away from protein-rich food.

Each bottle holds 30 capsules, one month’s supply. Taking it at the same time each day makes it easier to stay consistent.

No overnight miracles. We recommend at least three months of daily use, alongside a varied, balanced diet and a healthy lifestyle.

Do not exceed the recommended daily dose. Food supplements should not be used as a substitute for a varied diet. If you take any medication, especially blood thinners, check with your doctor or pharmacist first.

Nattokinase+ is manufactured in a GMP-certified facility in Ireland, following strict quality and safety standards at every stage of production.

Raw Material Testing & Certification

Every ingredient batch is supplied with a Certificate of Conformance, confirming independent testing for:

  • Microbiological contaminants
  • Heavy metals
  • Irradiation
  • Ingredient quantity (potency verification against label claims)

All raw materials are also confirmed non-GMO and TSE/BSE-free, in full compliance with EU food safety regulations.

Finished Product Testing

Independent microbiological testing is carried out on the finished product, via an accredited third-party laboratory, through our manufacturer, before any batch is released for sale.

The vitamin C content of the finished capsule has also been independently verified by a state analytical laboratory, confirming it matches the quantity stated on the label.

Why 4000 FU matters

FU (Fibrinolytic Units) measures the enzymatic activity of nattokinase—not only its weight. Nattokinase products containing the same weight may have different activity levels. This formula provides 4000 FU of standardized nattokinase activity.

Amazing stuff!! The benefits from taking Nattokinase+ over the last 3 months are so noticeable. I don’t have that groggy feeling that I used to have in the mornings and I find I don’t crash in the evenings like before. After coming down with the flu 2 weeks ago, I feel that, once I had kicked it, I was back to full health so quick - no lingering symptoms for weeks like I have experienced in the past!

Overall, I’m delighted with this supplement and will be continuing with my subscription far into the future!

I took this product for 3 months and felt great. More energy less pains in the bones and just feeling a bounce. As the summer draws to a close I have just purchased a further 3 months supply to give me a winter boost.

Game changer product. Had issues for years with low energy, no matter what I took supplements wise or the amount of sleep I got, nothing worked
Since taking Nattokinase+ I’ve felt the best I have in years. I would recommend this product to everyone

I’ve been taking Nakinatose for almost a year now. I feel so much better my joints ache so much less, my sleep is much more consistent and I’ve only had one chest infection since taking them. Before this I’d have had 3 or 4 infections a year. I definitely feel that these have helped me. I’m 61(F)

Really felt the effects after 2/3 weeks. My energy levels were more consistent & felt better all round!

I have asthma and for the last few winters I was getting a lot chest infections. They were coming nearly every 6-8 weeks. Since September I’ve been using nattokinase+ and I haven’t gotten sick once or even a chest infection which is some change! Great product.

Brilliant product I started at the end of last year. I was able to get back to feeling normal and energetic again after some bad viruses. Since I started, a lot of my family are now on it too and reaping the benefits massively!

I have been taking Nattokinase for approximately 6 months now. I have more energy and definitely sleeping better. I would recommend it to anyone and have done so.

I have been taking Nattokinase+ for 5 months and highly recommend it to anyone who needs a little boost. I took a chest infection in December and couldn't shake it off, after 3 antibiotics and a course of steroids my immune system was in my boots. I was literally struggling to get going every day and stay awake without a 4pm snooze. I've never been one for taking vitamins, enzymes or supplements as to be honest there are so many available it just confused me when I'd try to work out what I actually needed. It was only when Nattokinase+ was recommended to me by my aunt that I actually started to look into it. I took 2 every day for 6 weeks and then cut it back to one every day ever since. I can honestly say this has been the boost my system has needed for a long time so if you're feeling sluggish and need to get your body in recovery mode, Nattokinase+ has everything packed into one little tablet a day to get you boosted! Give it a go, you won't be disappointed!

I’m a 61 year old female and I have been taking these for about 6 months now. The difference I feel in my joints is amazing. I can run up and down stairs now. I feel totally energized. I highly recommend them to everyone.

I absolutely love this product, it's full of so much goodness and has made a huge difference to my energy levels. I am taking it for 3 months now and noticed a difference more or less immediately, within a few days for certain. I have much more clarity and focus at work, my concentration has improved, I sleep very well and wake in the morning feeling as if I have too. I highly recommend it to anyone feeling sluggish and tired all the time, this will give you a whole new lease of life. Well done Nattokinase+, 5 stars from me. ⭐️ ⭐️ ⭐️ ⭐️ ⭐️

I started taking this vitamin to support my immune system and boost my energy, and I’ve genuinely noticed a difference. When I first arrived in Australia, I was really struggling with jet lag, but this helped me feel more balanced and get back into a routine much quicker than I expected.

I’ve also felt more consistently energised, which has been such a bonus. I would highly recommend!!!

I have been using Nattokinase+ since September. In just under 2 weeks i began noticing improved overall sharpness and cognitive function when carrying out tasks at work, all that dreaded post covid brain fog significantly reduced. I can say for sure that my overall mental clarity has improved greatly since I began supplementing Nattokinase+.
Worth mentioning that I don’t remember the last time I had a cold or even a cough or runny nose – which, over the years I’d be the first one to catch as soon as flu season hit.

I have been using this product for over a month now and since week 2/3 have noticed a massive increase in my energy levels along with improvement in my sleep quality. I usually track sleep quality/recovery with a smartwatch and the results have been improving massively in the last month.

My energy levels continue to improve and generally feel much sharper and better focused as time goes on. I have recommended to family members who have issues with sleep quality and low energy levels and would recommend to anyone else with the same issues. Will continue to use and recommend this product going forward

I’m on my 2nd batch of Nattokinase+ now and find it a wonderful food suppliment, energy levels and focus are great. After a bad flu leading in to Christmas this has really helped me get back on track. Highly recommend

John Enda Flannelly

Since taking Nattokinase+, I have noticed improvement in my energy levels and I started sleeping better with weeks. Also, I have had bad eczema for the last 2 years and since taking Nattokinase+, I have noticed huge improvement with it. Would highly recommend to anyone.

Conor Weir

Have been taking Nattokinase+ consistently for 3 weeks and have started to find a number of improvements to my overall health after having long COVID.

The first benefit I noticed was my mental clarity, I felt this after 2 weeks, I am able to get out of bed with a clear head and no feelings of grogginess or brain fog.

Now, after the 3 week mark I feel my cardiac health slowly starting to improve again. During training I can feel my breath coming back a lot quicker and my heartbeat feels a lot more controlled.

I would highly recommend this product, not just for those who suffer from long COVID but for overall & general health.

Áine O'Malley

I started taking Nattokinase+ in November. After 3 weeks I started to recognise the benifits. I was
sleeping better and my energy levels were increasing. Having finished chemotherapy this year, Nattokinese+ has helped so much with reducing my brain fog. It is something I will continue to take.

Theresa Lydon

I was recommended Nattokinase+ by a friend who had seen reviews that it helped with post covid fatigue.
I had a recent sickness that left me feeling drained, fatigued so decided to give it a go. I’m 3 weeks in and I have to say I have so much more energy , less fatigued and brain fog has improved.
I used to wake up feeling exhausted despite a night’s sleep now feel more rested and definitely more energetic.
Highly recommend this product have family members on it now also.

As a healthcare professional I found 6 weeks of using Nattokinase very beneficial in terms of increased energy levels, mental clarity and less joint and muscle pain. I woke up feeling less fatigued and found myself an appropriate level of tired in the evenings.

Thomas Magee

Since starting Nattokinase+, I have experienced significantly improved sleep and energy levels, which has had big impacts on my activity levels and recovery as a result.

C
Conor Cusack

Before taking Nattokinase+ I struggled a lot with brain fog and sleep quality. After about 3-4 weeks I noticed a significant improvement in both of these and found my concentration and energy improve as a result. I used to depend on caffeine a lot to get through energy crashes throughout the day but these have reduced dramatically. I would highly recommend Nattokinase+ to anyone who has similar issues.

R
Robert Reapy

Nattokinase + increased my energy levels and helped relieve my muscle aches and joint pains. I also felt less brain fog and sharper.
Highly recommend

Basia Szperling

Ever since covid, I’ve been dealing with constant fatigue and brain fog. It felt like I was always tired, no matter how much sleep I got, and staying focused—especially at work—was a real struggle.
I decided to give this supplement a try, and honestly, I’m so glad I did. I’ve noticed a big difference in how I feel. Mornings aren’t a nightmare anymore—I actually wake up feeling refreshed and ready to start the day. That’s a huge deal for me, considering I used to sleep through my alarms more often than not.
The brain fog has definitely improved too. I feel more clear-headed and it’s so much easier to concentrate on what I’m doing, whether it’s at work or just day-to-day stuff.
Overall, I’m really happy with the results so far. It’s helped me feel more like myself again.

E
Evan O'Brien

Since I have started taking this supplement I have found my energy levels have increased and my sleep performance has shown positive trends! I would recommend this supplement to anyone looking to eliminate fatigue symptoms throughout the day!

M
Michal Sydor

Since starting this supplement, I’ve noticed a huge improvement in my energy and overall well-being. Before, even with 7–8 hours of sleep, I’d wake up tired and sluggish, struggling to get through the day. Now, my sleep feels deeper and more restorative, and I wake up feeling refreshed, energized, and ready to be productive right from the start of the day. It’s made a real difference in reducing my fatigue and improving my daily focus.

J
Jack Flanagan

Since taking Nattokinase I feel sharper and more capable of doing my day to day work without any brain fog, something I have been struggling with.
My sleep has definitely improved, before I used to wake up 2-3 times a night now I sleep all the way through.
Highely recommend this product for anyone struggling with these same issues !

Questions, answered plainly.

Everyone responds differently. Some people report improvements in energy and overall wellbeing within a few weeks, while others may need longer. Consistent daily use for 8–12 weeks is recommended to support longer-term recovery and resilience.

If you take any medication, especially blood-thinning medication, or if you have a medical condition, please check with your doctor or pharmacist before taking Nattokinase+.

Stop taking Nattokinase+ at least two weeks before any planned surgery or dental procedure.

Nattokinase+ is not recommended during pregnancy, while trying to conceive or while breastfeeding.

Nattokinase supports healthy circulation, but recovery involves more than one pathway. Nattokinase+ combines nattokinase with curcumin and bromelain to support inflammatory balance; vitamin C, zinc and black seed extract to support normal immune function; and piperine to enhance curcumin absorption. It provides broader nutritional support in one carefully formulated supplement.

FU stands for Fibrinolytic Units and measures the active enzyme strength of nattokinase not simply its weight in milligrams. Each Nattokinase+ capsule contains 100 mg of nattokinase providing 4,000 FU.

Individual experiences can vary, and food supplements should complement not replace—medical care, a balanced diet or a healthy lifestyle. If you experience an adverse reaction, stop taking the product and consult a healthcare professional. For questions about an order or return, contact info@fianahealth.ie before returning your product.

Nattokinase is an enzyme traditionally produced from natto, a fermented soybean food. The nattokinase in Nattokinase+ is derived from soy, so soy is declared as an allergen on our label.

If you have a soy allergy, we don’t recommend taking Nattokinase+. The enzyme goes through purification, but we can’t guarantee that no soy proteins remain. Even small traces can cause a reaction in some people.

If you’re unsure whether your sensitivity rules it out, please speak with your GP, allergist or pharmacist before use. You can also contact us for the full allergen information.
