GeneIII's 8 Clinical Trials: Real Data Behind the Supplement

GeneIII has conducted 8 human clinical trials on L-Ergothioneine, covering 7 health areas: liver health, menstrual pain, ovarian function, postpartum recovery, cognitive health, kidney health, and men's health.

The goal behind these studies is to provide consumers with verifiable data for the health concerns they actually care about — so that everyone who chooses GeneIII knows there's real clinical evidence backing the product they're taking every day.

When Late Nights and Busy Schedules Take a Toll on Your Liver

Irregular sleep, frequent socializing, a few too many drinks — and then your annual checkup shows liver enzyme numbers creeping up. You might not think of yourself as having a "liver problem," but those slowly rising numbers are telling you something.

GeneIII addressed this with a 30-day human trial (ChiCTR2400093739). Participants took 60mg of GeneIII L-Ergothioneine daily.

Results showed: ALT decreased by 21.52%, AST decreased by 19.64%, and GGT dropped significantly. Physical function improved by 39%, and sleep disturbance decreased by 51%. Zero adverse events throughout.

GeneIII L-Ergothioneine capsules contain 30mg each — the study dose was 2 capsules per day. If your checkup numbers are starting to trend upward, this is a daily option with clinical data behind it.

A Better Way to Deal with Monthly Cramps

Period pain is something many women deal with every single month. Painkillers help in the moment, but relying on them long-term isn't ideal.

GeneIII's dysmenorrhea trial (ChiCTR2500112557) offers a different approach. Participants took 120mg/day for 3 menstrual cycles. Results: 84% of participants saw meaningful symptom improvement, with an NNT of 2.0 — meaning for every 2 people who took it, about 1 experienced real relief. Zero adverse events. The preprint is published on medRxiv (DOI: 10.64898/2026.03.26.26349375).

GeneIII L-Ergothioneine is not a hormone medication or a painkiller. The study dose was 4 capsules per day (120mg). If you're looking for a long-term approach that doesn't depend on painkillers, this research provides a data-backed starting point.

Supporting Your Body After 35

Many women start paying closer attention to ovarian health after 35 — not necessarily because something is wrong, but because AMH levels are dropping on lab reports, or friends are starting to talk about it. You want to do something, but it's hard to know where to begin.

GeneIII conducted a dedicated trial on ovarian reserve function (ChiCTR2500104484), tracking core hormonal markers including AMH, FSH, E2, and Kupperman scores — all objective indicators of ovarian function. The trial is completed with published results.

If you're at this stage and want to be proactive, taking 1–2 GeneIII L-Ergothioneine capsules daily is a simple, data-backed way to start.

Getting Your Energy Back After Having a Baby

Postpartum recovery isn't just about healing physically. Many new mothers experience a persistent, hard-to-describe fatigue — poor sleep, low energy, feeling stuck at a low baseline for weeks or months.

GeneIII's postpartum recovery trial (ChiCTR2500114171) focused on exactly these issues. Results showed: quality of life scores improved by 35.94%, and fatigue levels decreased by 27.78%.

For women in the postpartum stage, GeneIII L-Ergothioneine capsules — 1–2 per day after a meal — can be incorporated into your daily recovery routine. It doesn't replace medical guidance, but it provides an additional layer of cellular-level support during a demanding period.

Keeping Your Mind Sharp as You Age

Cognitive decline is a slow process — by the time you clearly notice your memory slipping, the underlying damage has often been building for years. More people are recognizing that brain health needs attention early, not after problems become obvious.

GeneIII partnered with Anhui Medical University Affiliated Chaohu Hospital to conduct a trial on mild cognitive impairment (ChiCTR2500112606), currently underway. This marks an important step in extending GeneIII's research from physical health into brain health.

Data is still being collected, but if you have a family history of cognitive decline or notice your focus and memory aren't what they used to be, this is a direction worth watching. GeneIII L-Ergothioneine capsules — 1–2 daily — can be part of your long-term approach to brain health.

What GeneIII Is Working on Next

Kidney Health (ChiCTR2500108897) — Trial completed with published results, supporting L-Ergothioneine's potential role in kidney function.

Men's Sperm Vitality (ChiCTR2500111625) — Randomized, placebo-controlled, blinded design. 60 participants, 90 days. Results are expected soon, marking GeneIII's first completed study in men's health.

GeneIII's clinical program isn't a one-and-done effort. 8 registered trials across 7 health areas, with more underway.

For consumers, choosing a brand that keeps investing in research means the evidence behind your health choices keeps getting stronger over time.

GeneIII L-Ergothioneine capsules are one of the few L-Ergothioneine products backed by multiple human clinical trials.

Each capsule contains 30mg — the same ingredient, same purity standard used across all 8 studies.

Take 1–2 daily after a meal, and adjust based on your health needs.
