Visceral Fat Reduction

01

Reduce Deep Visceral Fat (The Type Menopause Specifically Increases)
When estrogen drops, your body stops storing fat around your hips and thighs and starts packing it deep around your internal organs. This is visceral fat — the hard, pregnant-looking kind a scale can't measure. You can weigh the same and still watch your waist change.

Ashitaba contains two rare chalcones — 4-hydroxyderricin and xanthoangelol — that activate AMPK, your body's cellular fat-burning switch. In a 12-week randomized, double-blind, placebo-controlled trial, adults taking this standardized extract showed a statistically significant reduction in visceral fat measured by CT scan.

A Smaller Waistline

02

Shrink Your Waistline (Even When the Scale Won't Move)

You cut calories. You lost 20 pounds. Your waist didn't change. This is the frustrating reality of menopausal fat storage — the scale moves but the midsection stays stubborn, no matter how hard you try.

The same 12-week human trial tracked waist circumference and found a significant decrease starting as early as week 8. Ashitaba targets the specific deep fat that makes the waist resistant, helping your clothes fit better before the scale even moves.

Blood Sugar & Belly Fat

03

Support Healthy Blood Sugar (The Hidden Driver of Belly Fat)

When estrogen drops, insulin sensitivity shifts. Your cells stop responding to insulin properly, sugar circulates instead of being used for fuel, and your body stores more of it as abdominal fat — a loop that gets harder to break over time.

In preclinical studies, Ashitaba's chalcones have been shown to activate AMPK and improve markers of insulin sensitivity and blood glucose. This helps explain why Ashitaba may support healthy blood sugar in a way that makes it easier to burn fat for fuel instead of storing it.

Ashitaba Influence How the Body Handles Fat

04

Support Healthy Adiponectin Levels (The Hormone That Tells Your Body to Burn Fat)

As visceral fat expands, it suppresses adiponectin — the hormone that signals your body to burn fat and improves insulin sensitivity. The more belly fat you have, the more your body silences the very signal that would help you lose it. It's a locked loop that gets harder to break the longer it goes on. Low adiponectin is tied to insulin resistance, which makes it easier to gain abdominal weight and harder to lose it.

In preclinical models, Ashitaba's chalcones have been shown to support healthy adiponectin levels, reduce fat accumulation in fat tissue, and lower circulating triglycerides. When adiponectin signaling is supported, the body is better positioned to pull fat out of storage and burn it for fuel — rather than hold onto it.

The Daily Bloat

05

Flatten the Bloating (It's Not Just Fat — It's Daily Discomfort)

Many women deal with two problems at once: deep belly fat that feels stuck, and daily bloating that makes the stomach look and feel even bigger. You eat half a bowl of soup and your stomach balloons for hours. Popular belly-fat supplements like high-dose berberine often make it worse.

Ashitaba's golden sap has been used for centuries as a digestive aid. Its compounds are naturally anti-inflammatory in the gut lining and help balance gas-producing bacteria. And because it's a liquid softgel, not a dry compressed pill, it glides through digestion without adding heaviness or water retention.

Meet Ashitaba's Signature Chalcones

06

Because Ashitaba is still unfamiliar in the US market, not every product labeled “Ashitaba” is delivering a meaningful amount of the specific compounds that were actually studied. The research above isn’t about Ashitaba in general; it’s about 4-hydroxyderricin and xanthoangelol specifically, at a measured dose.

Each 2-softgel serving of Yuuki contains 275 mg of standardized Ashitaba extract, providing 22 mg of naturally occurring chalcones. That means the amount of the active compounds is clearly stated rather than hidden behind a generic Ashitaba amount or proprietary blend.

This is the difference between an ingredient chosen because it photographs well on a label, and one chosen because there’s a specific, measurable amount tied to a specific body of research. It’s why Yuuki’s formulation uses a standardized, clearly measured amount of the compounds behind the research, rather than a marketing-friendly guess.

Why the Formula Includes MCT Oil

07

Chalcones are fat-soluble plant compounds, which is part of the reasoning behind formulating Yuuki with a source of dietary fat alongside the Ashitaba extract.

Each 2-softgel serving pairs 275 mg of standardized Ashitaba extract, providing 22 mg of naturally occurring chalcones, with 650 mg of MCT oil. It keeps the formulation focused on the Ashitaba and the compounds behind the research rather than adding a long list of unrelated ingredients.

Yuuki is also third-party lab-tested for purity and potency, with its Ashitaba sourced from Japan. The formula is non-GMO and gluten-free, adding another layer of transparency around what’s actually inside each serving.

before you go: the questions worth asking

Is this a weight-loss drug or a treatment for a medical condition?

Yuuki is a dietary supplement, not a medication, weight loss drug, or treatment for medical conditions. It isn’t intended to diagnose, treat, cure, or prevent any disease, including obesity or metabolic conditions. The research above reflects a specific clinical study on Ashitaba chalcone extract; individual results will vary.

Is it safe? Are there side effects?

Across the published human trials on Ashitaba chalcones, doses ranging from 16 mg of isolated chalcones up to 200 mg of chalcone powder were reported as well tolerated, with minimal side effects. As with any supplement, it’s worth checking with a doctor first if you’re pregnant, nursing, managing a health condition, or taking other medication.

How is this different from other menopause supplements?

Most menopause-support supplements are built around hormone-adjacent ingredients. Yuuki takes a different route: it’s built around a compound with a specific, published human study measuring visceral fat directly, rather than a broad blend of “supportive” herbs.

What should I look for to know it’s a quality product?

Check the details behind the ingredient name. Look for clear sourcing, a standardized extract, a stated amount of active chalcones, and independent testing for purity and potency. Yuuki checks each of those boxes, with Ashitaba sourced from Japan, a standardized chalcone-containing extract, and third-party lab testing.

“My Waist Finally Started Changing”

For years, my stomach was the one area that never seemed to respond the way the rest of my body did. I could lose a few pounds, but my waist still looked and felt the same. After staying consistent with my healthier routine and adding Yuuki, I started noticing my clothes fitting more comfortably around my middle. Seeing progress in the area that frustrated me most has been incredibly motivating.

“I’m Finally Seeing Progress Around My Middle”

I’ve always carried most of my extra weight around my stomach. Even when the scale moved, that round belly seemed to stick around. I started taking my diet and daily activity more seriously and added Yuuki to the routine. Over time, I began noticing a difference around my waist and my shirts started fitting better through the middle. That’s the kind of progress I actually wanted to see.

“I Feel Like My Health Is Moving in the Right Direction”

I originally started looking into Ashitaba because I wanted to do more for my metabolic health and the stubborn weight around my middle. I’ve been more mindful of what I eat, walking regularly, and taking Yuuki consistently. I’m feeling better about my routine, my waist doesn’t feel quite as stubborn, and overall I finally feel like I’m moving in the right direction instead of fighting the same battle over and over.

“Calmer overall after eating.”

It’s not about instant results, but the steady improvement is what made me keep using it consistently over time. I finally feel like my body is responding in a more balanced way.
