NCT06183307

Brief Summary

The study aims to evaluate the effect of the nattokinase enzyme on inflammation and markers of cardiovascular risk in participants with dyslipidemia. A longitudinal double-blind randomized clinical trial will be carried out, involving hypertensive participants with dyslipidemia for two months.

Outcome Measures

Primary Outcomes (1)

  • Change of inflammatory status in the participants

    Get blood samples to evaluate the supplementation effects in inflammatory biomarkers: interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), C-reactive protein (CRP).

    Baseline and 8 weeks

Secondary Outcomes (1)

  • Change in plasma fibrinogen levels, lipid peroxidation and improvement in lipid profile.

    Baseline and 8 weeks

Study Arms (2)

Nattokinase group

EXPERIMENTAL

Participants will receive 1 capsule per day, providing the active nattokinase daily, at a dosage of 100mg, standardized at 2,000 Fibrinolytic Units.

Dietary Supplement: Nattokinase

Placebo Group

PLACEBO COMPARATOR

The placebo group will receive the same amount of 100mg placebo, at the same time, containing corn starch.

Dietary Supplement: Placebo

Interventions

  • TG (TG ≥ 150 mg/dL or ≥ 175 mg/dL, without fasting);
  • Reduction in HDL-c (men \< 40 mg/dL and women \< 50 mg/dL) alone or in association with an increase in LDL-c or TG. If TG ≥ 400 mg/dL.
  • Individuals who are already using lipid-lowering therapy (statins or non-statins) will also be included.

You may not qualify if:

  • Participants with autoimmune and infectious diseases, diabetes, cancer and AIDS;
  • Pregnant women;
  • Participants using catabolic drugs or antibiotics
  • Participants on anticoagulant medication
