“I thought I just had to live with it…”

That’s what a lot of women believe.

And it makes sense.

Because most solutions don’t feel like solutions.

They feel like guesswork.

“Why does my body feel… off… and nothing I try seems to help?”

You eat clean.
You read labels.
You try the “good” supplements.

And still…

Something feels off.

Dryness.
Mood shifts.
That subtle feeling that your body isn’t responding the way it used to.

And the frustrating part?

You’re doing what you’re supposed to do.

It’s not your fault… and it’s probably not your body

Most estrogen products look clean on the front.

And then you turn the bottle around…

Fillers
Preservatives
Weak doses
Synthetic forms your body barely recognizes

And somehow, you’re expected to feel a difference.

Here’s the part most people miss

Your body doesn’t respond to labels.

It responds to what actually gets absorbed.

And when the formula is diluted, preserved, or poorly designed…

Your body quietly ignores it.

So what makes this different?

Simply Bi-Est was built on a simple idea:

If it’s not pure… it doesn’t belong.

✅ What you’ll find inside:

• Bioidentical estrogen is designed to match what your body already knows.
• A clean oil base for better absorption.
• No fillers.
• No preservatives.
• No unnecessary additives.

❌ What you won’t find:

• Cheap bulk ingredients.
• Hidden fillers.
• Artificial stabilizers.
• “Label dressing” ingredients that sound good and do nothing.

What this supports

Women use Simply Bi-Est Oil when they want support with:

• Hormonal balance during life transitions such as perimenopause, menopause, and post menopausal symptoms.
• Vaginal dryness and tissue comfort.
• Skin hydration and elasticity.
• Overall sense of hormonal stability.
• Systemic relief of perimenopausal, menopausal, and post menopausal symptoms. See below for detailed descriptions.
• Add this to your routine if progesterone-only therapy is insufficient to relieve your symptoms.
• Best when taken in combination with Simply Progesterone Oil. Especially if you still have your uterus.

Simply Bi-Est Across all stages (general benefits)

• Stabilizes body temperature regulation
• Supports libido and sexual function
• Helps maintain metabolic balance
• Contributes to overall well-being and energy

Simply Bi-Est for Perimenopause (transition phase)

Hormone levels fluctuate unpredictably here, and estradiol can help stabilize things.

Key benefits:

• Reduces hot flashes & night sweats (often inconsistent at this stage, works best when combined with progesterone)
• Improves mood swings & irritability by smoothing hormonal ups and downs
• Helps regulate menstrual irregularities
• Supports sleep quality
• May reduce brain fog and improve focus

Simply Bi-Est for Menopause (12 months after last period)

Estrogen levels drop significantly, leading to more persistent symptoms.

Key benefits:

• Relieves vasomotor symptoms (hot flashes, night sweats — one of the most effective treatments available)
• Improves vaginal and urinary health (reduces dryness, painful sex, urinary urgency, recurrent UTIs)
• Enhances mood and reduces the risk of depression
• Supports skin elasticity and hydration
• Improves sleep and overall quality of life

Simply Bi-Est for Postmenopause (long-term low estrogen state)

Now the focus shifts more toward long-term health protection.

Key benefits:

• Prevents bone loss (osteoporosis) Estradiol helps maintain bone density and reduces fracture risk
• Supports cardiovascular health (early use) May help maintain healthy blood vessels if started near menopause onset
• Maintains vaginal tissue health long-term
• May help preserve cognitive function (evidence is mixed but promising in early use)
• Helps maintain muscle mass and joint comfort

⚠️ Important considerations

Estradiol therapy isn’t one-size-fits-all:

• Often combined with progesterone if you still have a uterus (to protect the uterine lining).
• Risks can include blood clots, stroke, or breast cancer, depending on personal factors and dose. You should always use the lowest effective dose.
• Best outcomes are typically seen when started within ~10 years of menopause (“timing hypothesis”).

And it’s important to say this clearly...

This is not about forcing your body to do something unnatural.

It’s about giving it something it actually recognizes.

Why purity matters more than anything

You can take the “right” ingredient…

And still get no result.

Because:

• The form is wrong.
• The dose is weak.
• The formula is diluted.
• The formula has fillers that clog your skin's pores.

And when that happens, the outcome never shows up.

This is where things shift.

• When the formula is clean…
• When the ingredients are intentional…
• When nothing is in the way…
• Your body finally has a chance to respond.

Application Instructions

Shake well before each use.
Where to apply: Vulva, inner and outer labia.
How to apply: Place the desired dose on clean finger tips and rub into the inner and outer genitalia. It is not necessary to insert the dose inside the vagina.

Shelf Life: Preservative-free. Use within 1 year of opening.

For Topical Use Only - Not intended for oral supplementation.

Dosage Guidelines

Always use the lowest effective dose.

5-20 drops daily. Start with 5 drops and increase the dose by 5 drops after 6 weeks if the desired effect is not achieved. It is common to experience an adjustment phase each time you change the dose as your body adapts to the new hormone level.

How long before I see results?

Consistency matters more than intensity. Allow your body 6-10 weeks to adjust to the new hormone levels.

Your body responds over time, not overnight.

A simple decision

You can keep trying products that look good on paper…

And hope this time is different.

Or…

You can try something built on purity from the start.

The decision is yours.

Why HealthNatura

We don’t try to impress you with long ingredient lists.

We remove what doesn’t belong.

Because:

You’re not hard to help — you’re taking junk.

And once that’s gone…

Things start to make more sense.

Who is this for?

This product is designed for women who already know something is off and want a balanced estrogen therapy that addresses both the systemic symptoms of estrogen deficiency, like hot flashes and memory probelms AND the symptoms of vaginal atrophy, dryness, and urinary weakness. 

Not sure if Simply Bi-Est Oil is right for you?

You have options. First, read this article describing the symptoms of estrogen deficiency. Then, if you still suspect estrogen deficiency, consider a therapeutic trial using Simply Bi-Est or get some testing done: At-home hormone testing. Or talk to your doctor about testing your hormone levels.

Are you ready to stop guessing?

If that’s you, this may be worth trying.
