High End Ingredients

Why I Formulated This

Most myo-inositol supplements stop at myo and D-chiro-inositol alone. But inositol works better when your body can keep making and using its own. I've built that in. Magnesium is the cofactor for the enzyme that lets you synthesize myo-inositol yourself. Vitamin C clears methylglyoxal, a toxic byproduct of high insulin that blocks your body's ability to make its own myo-inositol. Skip either and you're pouring inositol into a system that can't ever make its own supply.†

Both ingredients here are naturally fermented and food-sourced, not synthetic isolates — the same myo-inositol and D-chiro-inositol 40:1 ratio the research uses, cleaner starting material.

How to Use It

Dose: 4 capsules daily (2,000 mg myo-inositol, 50 mg D-chiro-inositol), ideally split 2 morning and 2 evening with a meal. This 40:1 ratio is the most studied combination for supporting healthy ovulatory function and hormone balance.†

How long does myo-inositol take to work? Some women notice subtle shifts such as steady energy, and craving support within the first few weeks, though this varies person to person. Blood sugar markers can start responding in 8–12 weeks; cycle regularity support usually takes 3–6 months. Skin and hair-related support are the slowest to appear. †

Give it a full 3 months minimum before judging results.

When to Use It

Daily and ongoing to support regular cycles, especially with blood sugar swings, women focused on fertility and trying to conceive, or pregnancy.†

Pregnancy safety: Myo-inositol has a strong pregnancy safety record for a supplement. Seven randomized controlled trials have supplemented myo-inositol from the first trimester onward, studying its role in supporting healthy blood sugar and blood pressure during pregnancy. Still confirm with your OB before starting anything new in pregnancy.

Signs to Pause or Stop

  • GI upset in the first week or two? Start at 2 capsules daily for the first week, then work up to the full 4. Take it with a meal that has some protein or fat in it, not on an empty stomach and not with just carbs. Drink enough water throughout the day..
  • Still uncomfortable after 10 days at full dose? Drop back to 2 capsules.
  • No change at all after a full 3 months? Pause and talk with your doctor. You may need different support.
  • On metformin or another insulin-sensitizer? Check with your health professional first. The mechanisms overlap.

Stack Recommendations

  • Prenatal Essentials — if pregnant or conceiving, no timing conflict. Can take it together.
  • Fish Oil — same meal, reinforces insulin sensitivity†
  • Metabolic Nutrients — add if blood sugar balance is the main thing you want to support; hits the same pathway from a second angle. You can take this together or any time of day after food.†

Your cycle shows up whenever it feels like it, and you're tired of not knowing what's coming. Blood sugar swings and unpredictable cycles tend to travel together. If your period is more of a surprise than a schedule, a myo-inositol supplement built for cycle and blood sugar support is worth a look.†

You're trying to conceive and your cycle isn't cooperating. Ovulation depends on hormone and blood sugar signaling working together. This myo and D-chiro inositol formula is built to support that signaling, and inositol has a well-studied role in fertility support.†

Your weight won't move no matter what you do, and the cravings never let up. Sugar cravings and stubborn weight are often blood sugar problems wearing a different disguise. This works upstream of both to support healthy metabolism and blood sugar balance.†

You're seeing acne along your jawline, or hair where you don't want it and thinning where you do. These are often androgen-driven, and androgen production is closely tied to insulin. Support one, and you're supporting the other.†

You're pregnant or planning to be, and you want extra support for healthy blood sugar. Talk to your OB first. Myo-inositol has a solid body of pregnancy research behind it.†

You've been managing this for years and you're just tired. Fatigue, mood swings, cycle chaos, and cravings all in one body gets exhausting. If you've been white-knuckling it for a while, this hormone balance support is worth trying.†

This product is probably not right for you if:

  • You're on lithium. Inositol works on the same signaling pathway and can interfere with it.
  • You're on metformin or another insulin-sensitizer without your prescriber's input. Check with them first.
  • You want to see results in a week. This takes consistent use over months, not days.
  • Your cycle is already regular and your blood sugar is already stable. You don't need this.

Key Ingredients

Inside the Uncompromising Quality of Our Ingredients

  • Myo-Inositol (KeyPura™)
    This is a precision fermented myo-inositol, not extracted through chemical processing like most inositol on the market. Myo-inositol supports healthy insulin signaling and plays a central role in the hormone communication that ovulation depends on.†
  • D-Chiro-Inositol (Chirositol®)
    Extracted from carob pods without solvents. D-chiro-inositol works alongside myo-inositol in the body's natural 40:1 ratio, supporting healthy glucose metabolism and insulin sensitivity.†
  • Magnesium (as Di-Magnesium Malate)(Albion®)
    Magnesium is the cofactor for the enzyme your body uses to make its own myo-inositol. Without enough magnesium, that process slows down, so this formula supports your body's own inositol production, not just what's in the capsule.†
  • Vitamin C (as ascorbic acid)
    Vitamin C clears methylglyoxal, a byproduct of high insulin that interferes with your body's ability to make and use myo-inositol. This keeps the pathway clear so the rest of the formula can do its job.†

Frequently Asked Questions

What is the best myo-inositol and D-chiro-inositol ingredient?

Most inositol on the market comes from chemical processing of corn or wheat byproducts. This formula uses KeyPura which is a precision fermented myo-inositol. We also use Chirositol which is a D-chiro-inositol extracted from carob pods without solvents. Both are food based, not synthetic. I chose these specifically because clean sourcing matters as much as the dose.†

What is the best myo-inositol to D-chiro-inositol ratio?

The 40:1 ratio is the most studied combination, and it's the ratio naturally found in a healthy body. Products using a much higher D-chiro-inositol amount haven't shown the same benefit, and some research suggests too much D-chiro can work against you. I built this formula at 40:1 for that reason.†

How much myo-inositol should I take daily?

Most research on this myo-inositol supplement dose lands at 2,000 mg myo-inositol paired with 50 mg D-chiro-inositol daily, split into two doses. That's exactly what's in this formula: 4 capsules a day, 2 in the morning and 2 in the evening, with food.

How should I take myo-inositol?

Split the dose. Take 2 capsules in the morning and 2 in the evening, both with food, rather than all 4 at once. Inositol doesn't build up in your system, so splitting the dose keeps it working across the whole day instead of giving you one spike and then nothing. This is how the formula is dosed and how most of the research behind it was done.

Does myo-inositol support fertility?

Myo-inositol plays a role in the hormone and blood sugar signaling that ovulation depends on, which is why it shows up so often in inositol fertility support research. If you're trying to conceive, talk to your OB or fertility specialist about adding it to your routine.†

Is myo-inositol safe during pregnancy?

Myo-inositol has a strong safety record in pregnancy. Multiple studies have supplemented it from the first trimester onward at doses double what's in this formula, without an increase in serious adverse events. Still, always check with your OB before starting anything new in pregnancy.

What's the difference between myo-inositol and D-chiro-inositol?

They're both forms of inositol, but they do different jobs. Myo-inositol is the more abundant form and plays the bigger role in ovarian and insulin signaling. D-chiro-inositol supports a smaller, complementary piece of that same pathway. That's why the ratio between them matters more than the total amount.†

How long does myo-inositol take to work?

Some women notice subtle shifts within the first few weeks, though this varies person to person. Blood sugar markers can start responding in 8 to 12 weeks. Cycle regularity usually takes 3 to 6 months. Give it a full 3 months before you decide whether it's working for you.†

Can I take myo-inositol without a PCOS diagnosis?

Yes. This formula supports hormone and blood sugar balance, which matters whether or not you have a formal diagnosis. Plenty of women take it just for cycle support, cravings, or general hormone balance.†

Why does this formula include magnesium and vitamin C?

Because inositol works better when your body can keep making its own. Magnesium is the cofactor your body needs to make its own myo-inositol. Vitamin C clears methylglyoxal, a toxic byproduct of high insulin that blocks the process. Most d chiro inositol products skip both.†
