Study 1 — 2021

Body Composition & Liver Function

8 weeks 60 participants Overweight adults (BMI 25–30) Randomised, double-blind, placebo-controlled

Participants received 500mg fermented turmeric daily for 8 weeks. All outcomes measured against placebo group. Statistical significance threshold: p < 0.05.

Gut Health, Inflammation & Oxidative Stress

12 weeks 52 participants Adults with mild digestive discomfort Randomised, double-blind, placebo-controlled

Participants received 500mg fermented turmeric daily for 12 weeks. Primary endpoints: inflammatory markers, gut microbiome composition, oxidative stress.

Study 3 — S-Equol

Menopause, Skin & Cardiovascular Health

Women's Wellness 12 weeks 101–134 participants Randomised, double-blind, placebo-controlled

S-equol is a postbiotic metabolite produced from soy isoflavones by gut bacteria - but only 20-30% of Western women can make it. Women's Wellness delivers it directly. Aso et al. (2012) in the Journal of Women's Health randomised 126 non-equol-producing postmenopausal women to 10mg S-equol daily for 12 weeks, recording a 58.7% reduction in hot flush frequency vs. 34.5% in the placebo group (p=0.009). A parallel mood trial documented significant improvements in depression, tension, and fatigue scores. Oyama et al. (2012) in Menopause showed significant reductions in crow's-feet wrinkle area at both 10mg and 30mg doses (p<0.05). Further trials documented LDL reduction (p<0.01), arterial stiffness improvement, and bone mineral density preservation (p=0.027).

Study 4 — Nattokinase

Blood Pressure & Coagulation Factors

Men's Wellness 8 weeks 86 participants Randomised, double-blind, placebo-controlled

Nattokinase is a fibrinolytic enzyme produced during soybean fermentation, studied for cardiovascular and coagulation effects in peer-reviewed human trials. Kim et al. (2008) in Hypertension Research randomised 86 participants with untreated elevated blood pressure to 2,000 FU nattokinase or placebo for 8 weeks. Both systolic and diastolic blood pressure fell significantly vs. placebo, with renin activity also reduced - suggesting an ACE-inhibitory mechanism. Hsia et al. (2009) in Nutrition Research enrolled 45 participants across healthy, cardiovascular risk, and dialysis groups receiving 2,000 FU nattokinase daily for two months, recording significant reductions in fibrinogen, factor VII, and factor VIII - three independent risk factors for thrombotic events.

All highlighted results met the p < 0.05 threshold for statistical significance.

Ethics Approved

All human trials reviewed and approved by independent ethics boards.

Third-Party Verified

Studies conducted at independent research facilities, not in-house.

Questions

About the evidence.

All trials follow the gold standard: randomised, double-blind, placebo-controlled. Participants were randomly assigned to treatment or placebo groups. Neither participants nor researchers knew who received what. This eliminates bias and confirms that observed benefits come from the formula, not chance.

The 8-week trial showed significant body composition and liver improvements. The 12-week trial demonstrated substantial inflammatory and microbiome changes. For meaningful outcomes, we recommend consistent daily use for at least 8 weeks before assessing results.

These studies report average outcomes across all participants in the treatment group. Individual results vary based on baseline health, diet, lifestyle, and genetics. The statistically significant results indicate that the majority of participants experienced measurable improvements compared to placebo.

Across all human trials, no serious adverse events were reported. The formula was well-tolerated by all participants, with compliance rates exceeding expectations.
