Doctor Life / 01

Nattokinase & OPC

Made for your daily routine.

Each capsule provides 100 mg of nattokinase with an activity of 2,000 FU and 260 mg of grape seed extract. The extract supplies 225 mg of OPC and 20 mg of catechins and epicatechins, making its main fractions clear.

One capsule daily on an empty stomach provides a simple routine, with 60 days of use per bottle. It combines nattokinase and grape seed extract, with particular caution required for medication affecting blood clotting.

Nattokinase & OPC

Why care for circulation every day?

The circulatory system delivers oxygen and nutrients to tissues. Activity, nutrition, sleep, blood pressure management, and medical care are its foundation. Nattokinase is being studied in fibrinolysis-related processes, while grape seed proanthocyanidin research includes vascular function and oxidative stress.

Nattokinase & OPC

What research informs Nattokinase & OPC?

A study using a single 2,000 FU serving of nattokinase reported temporary changes in selected fibrinolysis and clotting measures. Reviews of grape seed extracts have assessed vascular outcomes. The finished combination in Nattokinase & OPC has not been established by those studies, so it should not be treated as an anticoagulant or a replacement for medical treatment.

Important information

Do not exceed the recommended daily serving. Food supplements should not replace a varied diet. A balanced diet and a healthy lifestyle are recommended.

If you take medication, use only under medical supervision. Consult your doctor if you take medicines, especially anticoagulants such as warfarin (Coumadin).

Science & sources

Understand the formula.

Nattokinase studies focus on fibrinolysis and blood pressure, while research on grape seed extracts examines OPC polyphenols in relation to vascular measures. These publications did not study the finished Nattokinase & OPC combination.

These publications concern the studied ingredients or formulas. They do not all evaluate the finished Doctor Life product, and research results do not guarantee individual outcomes.

01A single-dose of oral nattokinase potentiates thrombolysis and anti-coagulation profiles

Yuko Kurosawa, Shinsuke Nirengi, Toshiyuki Homma et al.

Scientific Reports (2015), 5, 11601. DOI: 10.1038/srep11601; PMID: 26109079.

In a double-blind crossover study, a single 2,000 FU dose of nattokinase affected several measures of fibrinolysis and clotting, with values remaining within normal ranges. One capsule of this product provides the same declared activity.

02Effects of nattokinase on blood pressure: a randomized, controlled trial

Ji Young Kim, So Nam Gum, Jong Keun Paik et al.

Hypertension Research (2008), 31(8), 1583-1588. DOI: 10.1291/hypres.31.1583; PMID: 18971533.

An eight-week randomized study evaluated nattokinase in people with elevated blood pressure. Favorable changes in systolic and diastolic blood pressure were observed. The study examined nattokinase, not its combination with OPCs.

03The impact of grape seed extract treatment on blood pressure changes: A meta-analysis of 16 randomized controlled trials

H. Zhang, A. Liu, P. Niu et al.

Medicine (Baltimore) (2016), 95(33), e4247. DOI: 10.1097/MD.0000000000004247; PMID: 27537554.

A meta-analysis of 16 randomized trials examined grape seed extracts, a source of proanthocyanidins. The findings showed favorable changes in selected blood pressure measures, but the formulations and doses differed from Nattokinase & OPC.

FAQ / Nattokinase & OPC

Good questions. Clear answers.

Talk to us ↗

Why combine nattokinase with OPC?

Nattokinase provides 2,000 FU of enzyme activity, while grape seed extract supplies proanthocyanidins and polyphenol monomers. The formula combines these distinct ingredients in one capsule.

What does 2,000 FU mean?

FU stands for fibrinolytic units. It describes the enzyme's activity rather than simply its 100 mg weight.

How much OPC is in each capsule?

One capsule contains 260 mg of grape seed extract, including 225 mg of OPC and 20 mg of catechins and epicatechins.

Why take the capsule on an empty stomach?

Take one capsule on an empty stomach with water, separate from a meal.

How long does a bottle last?

A bottle of 60 capsules provides a 60-day supply at one capsule daily.

Does the product contain soy?

Yes. The nattokinase is derived from fermented soybeans. Do not use if you are allergic or intolerant to the product.

Can I take it with medication?

If you take medication, use this product only under medical supervision, particularly with anticoagulants such as warfarin (Coumadin).
