Hi, I'm Dr. Blane.
For 30 years, I've been the doctor women over 35 come to when nothing else has worked. When the diets stop moving the scale. When the trainers stop helping. When their old doctor tells them "it's just aging" and shows them the door.
What I've learned in those 30 years is that most of these women don't have a fat problem. They have a belly full of inflammation their body can no longer clear on its own. And once you fix that, the belly finally moves.
This page is what I tested to find out what actually works.
You can find out more about me on Instagram.
Why a Family Medicine Doctor Started Looking at Glutathione
The women walking into my clinic today are not the same women I saw when I started practicing 30 years ago.
The food we eat today has fewer nutrients than it did a generation ago. Our air, water, and household products expose us to more toxins than any generation before us. Stress levels are higher. Sleep is worse. All of that forces the body to burn through its master antioxidant — glutathione — faster than it can make it. By 35, women's levels start dropping off a cliff. And once they do, the body loses its ability to clear the daily inflammation. That's the belly that won't move. That's the puffy face. That's the weight stuck no matter what you eat.
↓ GSH
Glutathione levels drop by up to 50% between ages 20 and 65
↑ Toxins
The average American is exposed to over 80,000 chemicals daily, most unregulated
40%
Over 80% of my female patients over 35 report bloating that "won't respond to diet"

After 30 years of practice, this isn't news to me. But it's something I couldn't ignore anymore.
Before I go any further: no supplement replaces movement, sleep, and eating like an adult. Those are the foundation. I make sure every patient has those locked in first. Supplements are the final piece — not the starting point. But if a woman's body after 35 can't produce enough of its own master antioxidant to keep up with modern life, even with a clean diet, then smart supplementation isn't optional. It's insurance.
Here's what I keep seeing in my clinic, over and over.
A woman in her 40s walks in. She's frustrated. She's been trying to lose 15 pounds for four years. She's cut carbs. She's added protein. She's been to the gym five days a week. Nothing moves. Her belly sticks out over every pair of jeans she owns. She feels puffy from the moment she wakes up. By noon she looks like she's six months pregnant. And every other doctor she's seen told her the same thing — "it's just aging, try harder."
So she started looking at the shot. Everyone's on it. Her sister's on it. Two women at work are on it. It's $1,000 a month, hollows out her face, gives her nausea, steals her muscle along with the fat, and the second she stops, the weight comes right back. But at least, she thinks, it moves the scale.
Here's what I tell her, and what took me 30 years to fully understand.
Most women over 35 don't have a fat problem. They have an inflammation problem. What they're seeing in the mirror isn't extra fat — it's swollen, inflamed tissue their body has stopped clearing. The scale hasn't gone up because they're eating too much. It's gone up because their body is holding onto years of inflammation it can't get rid of anymore. The shot doesn't fix that. It just overrides your appetite until you stop paying.
Fix the inflammation, and the "weight" comes off — because a lot of it was never fat to begin with.
That requires specific support that a shot, a greens powder, a berberine pill, or another generic multivitamin simply doesn't provide
So I set out to find the best solution specifically for women over 35 stuck in this exact place. I pulled apart the five options my patients ask me about most — the shot, the viral pills, the greens powders, and two of the most popular glutathione products on the market. I analysed every one professionally. I tested them on my patients over 8–10 weeks each. And one result genuinely surprised me.
My #1 pick wasn't a brand I'd ever heard of. I discovered it because I noticed 308 clinicians on FrontrowMD — real doctors, nurse practitioners, and physician associates who put their license on the line — kept sharing it with their own patients. When I pulled apart the formula, I understood why.
How I Tested
12 months total. 8–10 weeks per solution with washout periods between them. Anything shorter tells you nothing.
Professional label analysis. I cross-referenced every ingredient against the clinical research on absorption, cofactor synergy, and inflammation. Verified manufacturing claims and certifications independently.
Real patient tracking. Bloating at 7am, 12pm, 4pm, 9pm. Waistband tightness. Morning puffiness. Bathroom regularity. Energy consistency. Whether their jeans buttoned by week six.
Cost and side-effect analysis. Price per month, plus what patients actually gave up to take it — face volume, muscle mass, energy, digestion.
My non-negotiables:
— Actually addresses the root cause (inflammation), not just the symptom (appetite)
— Full dosage transparency — no proprietary blends
— Third-party testing for purity and potency
— Ingredients at clinically studied doses
— Doesn't leave patients worse off when they stop
My Top 5 — Ranked
These are the five solutions women in my clinic ask me about the most. Each addresses the same problem — the belly that won't move, the weight that won't budge — from a completely different angle. Only one addresses the root cause. The others treat symptoms.
Fair warning: my #1 pick wasn't a brand I'd heard of before. I discovered it because 308 clinicians on FrontrowMD — real medical professionals sharing supplements with their own patients — kept including it on their personalised patient pages. That made me curious enough to pull apart the formula. What I found surprised me.
🥇
BEST OVERALL — #1 PICK
★★★★½ 4.9 / 5
Cata-Kor Liposomal Glutathione
The formula that actually addresses the inflammation
~ $1.33 / day
The only solution I tested that fixes the root cause of the belly instead of overriding the symptom. Trusted by 308 clinicians on FrontrowMD — real doctors sharing it with their own patients.
I'd never heard of Cata-Kor before this comparison. The reason I included it? I kept seeing it show up on the personalised patient pages of clinicians I respected. 308 medical professionals were including it in the products they share with their own patients. These are people whose license depends on two things: what they recommend being safe, and it actually working. If clinicians at that level are sharing a supplement, the formula has to be bulletproof.
So I ordered it, pulled apart the label, and was genuinely impressed. Here's what's inside:
FULL FORMULA — 5 INGREDIENTS, FULLY DISCLOSED
Liposomal Glutathione (1,000mg) · Resveratrol (100mg) · Vitamin C (50mg) · Selenium (55mcg — 100% DV) · Riboflavin B2 (5mg — 385% DV)
WHAT I LOVE
Actually addresses the inflammation driving the belly, instead of just overriding appetite like the shot
Full 1,000mg glutathione dose — highest oral dose I found in any product
Only formula with a real cofactor stack — resveratrol tells the body to make more of its own glutathione, vitamin C recycles it, selenium fuels the enzymes that neutralise inflammation
Liposomal delivery — wraps glutathione in a lipid layer so it survives digestion and reaches the bloodstream, same idea as an IV drip without the needle or the $300 clinic visit
NSF Certified, ISO/IEC 17025 lab tested, GMP facility, Non-GMO, Vegan
Capsule format — no sulfur taste, no gag, no refrigeration
+ Capsule format — no sulfur taste, no gag, no refrigeration
~$1.33/day — a fraction of what the shot costs, a fraction of what Cymbiotika costs
90-day money-back guarantee
Free NAD+ Core bottle, free Biological Age Test, free shipping
4.9 star average plus 308 FrontrowMD clinicians sharing it
WHAT I LOVE
Contains soy (from the sunflower/soy phospholipid used in the liposome)
Newer brand — fewer years on the market than Cymbiotika
MY EXPERIENCE
Around week two, my patients started messaging me that the belly they'd accepted as "just how I look now after 40" was softening. By week four, their waistbands weren't digging into them by 3pm anymore. Their faces looked less puffy in morning selfies. A few told me their husbands asked what they'd done differently. One patient — I'll call her Sarah, 43, two kids, four years post-baby, three years of asking me about the shot — buttoned her pre-pregnancy jeans for the first time by week six. She'd been sucking her stomach in behind the wheel for four years. After 30 years of professionally sceptical practice, that consistent pattern across multiple patients is what actually addressing inflammation looks like.
Bottom line: The only solution I tested that goes after the root cause — the inflammation that's been holding onto the weight — instead of overriding a symptom for as long as you're willing to keep paying. Highest dose, only real cofactor stack, capsule convenience, full transparency, clinician-endorsed, and a fraction of what most of my patients are spending on the shot. This is the one.

#2 — BEST LEGACY SUPPLEMENT BRAND
★★★★ 4.2 / 5
Cymbiotika Liposomal Glutathione
Premium liquid pouch
~$3.05 / day ($88/month)
Endorsed by celebrities like Kendall Jenner and Hailey Bieber. The most aspirational glutathione brand on the market — but only 150mg per pouch. My patients love the taste. They just don't lose the belly.
Cymbiotika is the aspirational category leader. 200+ million pouches sold. In Target and Ulta. Full transparency on every dose. Their Citrus Vanilla flavour is legitimately good tasting. It's the brand every woman coming into my clinic has already heard of. So I had to include it.
FULL FORMULA — (per pouch)
Reduced Glutathione (150mg) · Phosphatidylcholine (20mg) · CoQ10 as Ubiquinol (20mg) · PQQ · Riboflavin B2 (1mg)
WHAT I LOVE
Full transparency on every dose — no proprietary blends
Soy-free (uses sunflower phospholipids)
Includes CoQ10 for mitochondrial support
Genuinely enjoyable citrus vanilla flavour
Massive brand trust — 4.9 stars across thousands of reviews
Convenient single-serve pouches for travel
WHAT COULD BE BETTER
Only 150mg glutathione per pouch — 6.7x less than Cata-Kor
No resveratrol, no selenium, no meaningful vitamin C — missing the cofactors that actually turn glutathione into real inflammation control
$88/month one-time — nearly triple the cost per serving of Cata-Kor for a fraction of the dose
Recurring customer complaints on Trustpilot and iHerb about "makes my stomach bubble all day" and "gave me nausea"
Absorption claims (3x higher, 50% blood level increase) come from an internal brand-funded study that outside labs have not verified
MY EXPERIENCE
My patients on Cymbiotika enjoyed the ritual and the taste. A few reported skin looking slightly brighter within a couple weeks. But the belly and bloating shift I saw with Cata-Kor wasn't there. At 150mg with no cofactor stack, the formula simply doesn't have enough working ingredients to move the needle on the inflammation driving the weight. One patient did the math and realized she'd need almost seven pouches a day at $88/month to match Cata-Kor's dose.
Bottom line: A lovely product for daily skin glow if you love the ritual. But if you're here because your belly won't move, 150mg without cofactors is not going to solve the problem. My patients loved it, then quietly stopped ordering it.

#3 — THE OPTION MOST WOMEN CONSIDER FIRST
★★★½ 3.5 / 5
The Shot (GLP-1 Injections)
Weekly injection
~$1,000+ / month
The shortcut every woman in my clinic asks about. It works — until it stops. And it comes at a cost most women don't understand until it's too late.
I'm not against the shot. For a specific patient — significant clinical obesity, real metabolic disease, exhausted other options — it can genuinely change their life. But that's not who's asking me for it. Who's asking me for it is a woman with 15–20 pounds of stubborn belly and puffiness that won't move. And for her, the shot is the wrong tool.
HOW IT WORKS
A synthetic version of a hormone (GLP-1) that overrides your appetite. You stop feeling hungry. You eat less. The scale drops. That's it.
WHAT I LOVE
The scale genuinely moves — patients see 15-30 pounds down in the first few months
Well-studied for actual diabetes and clinical obesity
Prescribed by a real doctor, real monitoring
Simple weekly injection
WHAT MOST WOMEN DON'T HEAR UNTIL AFTER
~$1,000/month, mostly not covered by insurance
73% of women on it report gastrointestinal side effects — nausea, vomiting, diarrhea
"Ozempic face" is real — the fat loss hollows out cheeks, temples, under-eyes, leaving women looking gaunt and older
Steals muscle along with fat, which slows metabolism long-term
The second you stop, the weight comes back — often faster than it came off
Emerging side effects the medical community is still catching up on — menstrual changes, hair loss, muscle loss, mood changes
It doesn't fix any of the underlying inflammation — it just overrides your appetite for as long as you keep paying and injecting
MY EXPERIENCE
I have patients who did well on the shot. I also have patients who lost 25 pounds, hated how their face looked, stopped injecting, gained 22 back in six months, and now have less muscle than they started with. The scale isn't the whole picture. Muscle, face volume, energy, and long-term metabolic health matter too. And none of my shot patients felt that their underlying inflammation, digestion, or energy improved — they just weren't hungry.
Bottom line: If you have significant clinical obesity, talk to your doctor about it. If you're a 45-year-old woman with 15 pounds of stubborn belly that won't move, the shot is the wrong tool for the job. It doesn't fix what's actually wrong. It just overrides the symptom for as long as you keep paying — and the second you stop, you're back where you started, minus a chunk of your face and your muscle.

#4 — THE VIRAL "NATURAL SHORTCUT"
★★★ 3.0 / 5
Berberine ("Nature's Ozempic")
Daily capsule
~$25–40 / month
The viral supplement every woman on my Facebook feed has Googled. It has real research behind it — but the reality is a lot smaller than the headlines.
Berberine went viral in 2023 as "nature's Ozempic." It's a plant compound with genuine research on blood sugar and insulin sensitivity. My patients ask me about it constantly. Here's the honest picture.
HOW IT WORKS
Plant-derived compound that modestly improves insulin sensitivity and blood sugar regulation over time.
WHAT I LOVE
Genuinely helps insulin sensitivity in people with metabolic issues
Cheap
Widely available
Some real research supporting modest weight-related outcomes
WHAT'S OVERSOLD
The "nature's Ozempic" comparison is marketing, not science — the actual weight loss in studies averaged about 5 pounds over 8+ weeks at high doses
GI side effects are extremely common — cramping, diarrhea, nausea, especially at the doses needed for any effect
Interacts with common medications including statins, blood thinners, and diabetes medications
Doesn't address inflammation at all — it's purely an insulin play
Most viral berberine brands are underdosed relative to the studies
MY EXPERIENCE
I've had patients try berberine hoping for the viral results. What they got was a modest improvement in energy and some stomach discomfort. The scale barely moved. It's not useless — for a patient with actual insulin resistance it can help. But for the average 40-year-old woman looking to fix her belly, it's not the answer. It's targeting the wrong mechanism.
Bottom line: Berberine is a fine tool for insulin sensitivity in the right patient. But the "nature's Ozempic" framing is oversold, it doesn't touch the inflammation actually driving the belly, and the side effects catch most people off guard.

#5 — THE VIRAL "FLAT BELLY" GREENS
★★ 2.5 / 5
Bloom Nutrition Greens & Superfoods
Daily greens powder
~$40 / month
The Instagram-viral greens powder promising a "flat belly." My patients bring it up constantly. What most of them don't know: the reviews complaining about bloating outnumber the ones praising it.
Bloom is one of the most-marketed greens powders on the internet. It has a beautiful brand. It tastes like candy. And it built its entire positioning around a "de-bloat" promise. So I dug into it.
HOW IT WORKS
Fruit and vegetable powder blend with digestive enzymes and probiotics, marketed as a "de-bloating" morning drink
WHAT I LOVE
Genuinely tastes good — kids will drink it
Convenient way to add some fruit/veg flavor to your morning
Big trusted brand with good customer service
Not expensive relative to premium greens brands
WHAT COULD BE BETTER
The single most common negative review on Walmart, Amazon, and Trustpilot is that it causes bloating in the exact women it's marketed to
Another verbatim quote: "Although it says it helps with bloating, nope. I swell up again after this drink"
Another verbatim quote: "Although it says it helps with bloating, nope. I swell up again after this drink"
Contains a proprietary blend, meaning you can't verify the actual doses of anything
No glutathione, no cofactor stack, nothing that addresses the underlying inflammation driving the belly
Weight/de-bloat claims are marketing, not backed by clinical trials on the finished product
MY EXPERIENCE
I've had multiple patients come in complaining of worse bloating after starting Bloom. When I looked at the ingredient panel, it wasn't surprising — high-FODMAP ingredients that trigger bloating in a huge percentage of women over 35, combined with digestive enzymes at unspecified doses. It's a tasty morning drink. It's not a de-bloat solution. And for a lot of my female patients, it's actively making things worse.
Bottom line: If you like the taste and drink it as a treat, no harm done. But if you're buying it because Instagram promised a flat belly, look at the reviews before you commit. The complaint most people report is exactly the thing it's marketed to fix.
TRY Bloom Nutrition →What I Learned After 12 Months
When I started this comparison, I expected the shot to be the clear #1. It's what my patients ask about the most. It moves the scale the fastest. Every other option looked, on paper, like a compromise.
But when I stripped everything back and looked purely at what actually happens inside my patients' bodies over months and years — the ranking flipped completely.
Here are the four things twelve months taught me:
1.
Most women over 35 don't have a fat problem. They have an inflammation problem. What they're seeing in the mirror isn't extra fat — it's swollen, inflamed tissue their body has stopped clearing. That's why the diet doesn't work. That's why the gym doesn't work. That's why the shot moves the scale but doesn't make them feel better underneath. Fix the inflammation, and the "weight" comes off — because a lot of it was never fat to begin with.
2.
The shot is the wrong tool for the wrong problem for most women asking me for it. It doesn't fix the inflammation. It doesn't fix the digestion. It doesn't fix the hormones. It overrides one symptom — appetite — for as long as you're willing to inject and pay. And it costs you your face, your muscle, and thousands of dollars along the way. For a 45-year-old woman with 15 pounds of stubborn belly, that's not a solution. That's a hostage negotiation with your own body.
3.
The viral shortcuts don't fix the mechanism either. Berberine targets insulin, not inflammation. Bloom targets your Instagram algorithm, not your bloating. Cymbiotika targets skin at a dose too low to touch the belly. They're all treating different symptoms — none of them are fixing what's actually broken underneath.
4.
The best solution I found wasn't the most famous one. Cata-Kor was a brand I'd never heard of. But when I pulled it apart professionally and put it in front of my patients, it did what none of the others did — it fixed the underlying inflammation, and the belly, the puffiness, and the stuck weight followed naturally. Sometimes the best products don't have the biggest marketing budgets. They have 308 clinicians quietly sharing them with their own patients.
Final Recommendations
BEST OVERALL FOR WOMEN OVER
35 Cata-Kor Liposomal Glutathione. The only solution I tested that addresses the root cause — the inflammation driving the belly — instead of overriding a symptom. Highest dose, only real cofactor stack, full transparency, clinician-endorsed, and a fraction of what my patients are spending on the shot. This is the one.
BEST LEGACY SUPPLEMENT BRAND
Cymbiotika. A beautiful product for daily skin glow if you love the ritual. But at 150mg with no cofactors, it won't move the belly.
IF THE SCALE IS ALL YOU CARE ABOUT
The shot. Talk to your doctor. Understand what you're signing up for — the face, the muscle, the rebound, the monthly cost. It's not the wrong tool for every woman. But it's the wrong tool for most.
FOR INSULIN SENSITIVITY, NOT BELLY
Berberine. A real tool for the right patient. Not a weight loss shortcut. Skip it if bloating is your main issue.
SKIP THIS ONE
Bloom Nutrition Greens. Tasty morning drink. Not a de-bloating solution. The reviews tell the truth.
