About this product

The Healthy Gut Girl EstroClear Smart Stack is an advanced estrogen metabolism and detox-support formula built around three core pathways: estrogen metabolism, methylation, and antioxidant detox defense.

With DIM, Choline, NAC, Milk Thistle, Zinc Picolinate, Vitamin C, and Organic Broken Cell Chlorella, EstroClear is designed for women who want targeted support for healthy estrogen metabolite processing, liver detox pathways, glutathione status, and whole-body antioxidant defense.

DIM anchors the formula for estrogen metabolism support. Choline supports methylation capacity. NAC supports glutathione-related antioxidant defense. Milk Thistle supports liver health. Chlorella adds a green detox and elimination-support angle, while Vitamin C and Zinc round out antioxidant and cellular support.

EstroClear is a more complete approach than a basic DIM-only supplement — designed to help you metabolize, methylate, and defend.

Suggested use

Take one daily serving as directed on the label, preferably with food. EstroClear is best used consistently as part of a broader routine that supports digestion, elimination, adequate protein intake, hydration, and liver health.

Do not exceed the suggested serving unless directed by your healthcare provider.

About monthlees

The supplement industry is built on inflated pricing, confusing labels, and aggressive marketing.

Monthlees exists to fix that.

We believe:

  • Supplements should be clinically dosed
  • Pricing should be transparent
  • Testing should be independent
  • And customers shouldn't pay for influencer commissions or retail margins

Instead of hiding costs inside the product price, we use a simple membership model — so you pay what supplements actually cost to make.

Shipping & returns

• Shipping: Orders are processed within 1–2 business days. Standard delivery takes 3–7 business days depending on your location.

30 Day Money Back Guarantee

Your routine should feel simple, supportive, and worth it. If EstroClear is not a fit for you, contact support@monthlees.com within 30 days and we’ll help make it right.

Estrogen support far beyond DIM alone

EstroClear was built to support the full estrogen-clearance pathway in the body: metabolism, methylation, liver support, antioxidant defense, and elimination.

  • DIM

    DIM

    The primary estrogen metabolism ingredient in the stack, included at 300 mg per serving.

  • Choline

    Choline

    Supports methylation capacity through one-carbon metabolism, helping round out the estrogen metabolite processing story.

  • NAC + Vitamin C

    NAC + Vitamin C

    Antioxidant-support nutrients that help support glutathione status and cellular defense.

  • Milk Thistle + Organic Chlorella

    Milk Thistle + Organic Chlorella

    A liver and green-detox pairing for women who want broader clearance and elimination support.

How it works

  1. Metabolize

    Step 1: Metabolize

    DIM supports healthy estrogen metabolism, helping the body process estrogen metabolites through natural pathways.

  2. Methylate

    Step 2: Methylate

    Choline supports methylation capacity through one-carbon metabolism, an important part of healthy estrogen metabolite processing.

  3. Defend

    Step 3: Defend

    NAC, Milk Thistle, Vitamin C, Zinc, and Chlorella support glutathione status, liver detox pathways, antioxidant defense, and natural clearance.

The science behind the ingredients

EstroClear is built around research-supported pathways involved in estrogen metabolism, methylation, glutathione-related antioxidant defense, and liver support. DIM has human evidence for influencing urinary estrogen metabolite ratios. Choline supports methyl-donor pathways through one-carbon metabolism. NAC is included for antioxidant and glutathione-related support around reactive estrogen metabolite defense. Milk Thistle is included for liver and antioxidant support, with human liver-health evidence that is promising but still mixed and context-dependent.

Human study DIM

DIM and urinary estrogen metabolite balance

Human research has found that DIM supplementation can modulate estrogen metabolism, including an increased ratio of 2-hydroxyestrones to 16α-hydroxyestrone. This supports DIM as the estrogen-metabolism anchor of the EstroClear formula.
Pilot study DIM

DIM supplementation and urinary hormone metabolites

A pilot study in postmenopausal women with a history of early-stage breast cancer evaluated the effects of DIM supplementation on urinary hormone metabolites. This adds support for DIM’s role in estrogen-metabolism research, while the PDP should avoid disease-treatment claims.
Mechanistic research NAC

NAC and reactive estrogen metabolite defense

Research on catechol estrogen quinones and estrogen-DNA adducts identifies N-acetylcysteine as a compound of interest for reducing formation of estrogen-DNA adducts. This supports an antioxidant defense angle, not a direct claim that NAC clears estrogen.
NIH fact sheet Choline

Choline as methylation support

NIH notes that choline needs rise when folate intake is low because choline can serve as an alternate methyl-donor pathway. This supports the formula’s methylation-positioning for healthy estrogen metabolite processing.
Systematic review Milk Thistle / Silymarin

Silymarin and liver enzyme research

A systematic review suggests silymarin may have favorable effects on liver enzyme levels in some contexts, especially metabolic liver conditions, but findings are context-dependent. This supports cautious liver-support language rather than aggressive detox claims.

How EstroClear stacks up against typical hormone-support formulas

Many estrogen-support products stop at DIM. EstroClear is designed to support a broader estrogen-processing story: metabolism, methylation, liver support, glutathione-related antioxidant defense, and green detox support.

The honest math on building an estrogen-support stack

To recreate EstroClear separately, you would typically need multiple products: DIM, Choline, NAC, Milk Thistle, Vitamin C, Zinc, and Chlorella. EstroClear puts the core stack into one streamlined daily system.

Frequently asked questions

Everything you need to know about Monthlees member pricing, subscriptions, and how checkout works.

Is EstroClear just a DIM product?
No. DIM is the estrogen metabolism anchor, but EstroClear also includes Choline for methylation support, NAC for glutathione-related antioxidant defense, Milk Thistle for liver support, plus Vitamin C, Zinc, and Chlorella.
Why did you include Choline?
Choline supports methylation capacity through one-carbon metabolism. That makes it a smart addition for a formula focused on healthy estrogen metabolite processing.
Can I take EstroClear while pregnant, nursing, or trying to conceive?
Do not use EstroClear during pregnancy, nursing, or while trying to conceive unless specifically directed by your healthcare provider. You should also consult your healthcare provider if you use hormone therapy, take medications, or have a hormone-sensitive condition.

Why I created monthlees...

When I was 19 years old, I was diagnosed with a brain tumor. That experience forced me to start asking deeper questions about how the human body actually works.

Over the next 18 months, I immersed myself in studying health, nutrition, and neuroscience — eventually earning my degree in Neuroscience from Duke University. Along the way, I discovered something powerful: the body is incredibly resilient & inherently self-healing when it’s given the right support.

Strategic nutrition and supplementation became a major part of my own health journey. And over the last two decades, I’ve devoted my life to helping millions of people around the world take a more proactive role in their health.

That experience completely changed how I thought about health — and ultimately shaped the way Monthlees was built.

I created Monthlees because I was tired of seeing people pay premium prices for supplements that were under-dosed, over-marketed, and difficult to trust.

My goal is simple: build the kind of brand I would want for myself and my family — with better ingredients, transparent formulas, meaningful dosages, and a business model built on long-term trust.
