Questions
What is Four Leaf?
Four Leaf is a women's hormonal wellness brand built around one belief: that supporting your body's natural balance works better than overriding it. Our first product, Myo & D-Chiro Inositol+, restores the physiological 40:1 ratio your body already keeps.*
What's the difference between MI and DCI?
Myo-inositol (MI) and D-chiro-inositol (DCI) are two related nutrients your body converts from one another. MI primarily supports FSH signaling and egg quality, while DCI supports insulin sensitivity and androgen regulation. The ratio between them determines whether they help or work against each other.*
Why 40:1 specifically?
Research measuring healthy follicular fluid found MI and DCI naturally occur in a 40:1 ratio. Clinical trials comparing multiple ratios found 40:1 most effective for restoring ovulation and normalizing hormonal markers — while higher DCI ratios were linked to reduced egg quality.*
How long until I notice a difference?
Most women in clinical studies were assessed at 3 to 6 months of consistent daily use. This is a ritual, not an overnight fix — we recommend committing to at least one full subscription cycle before evaluating results.*
Is this safe with birth control or other medication?
Inositol is generally well tolerated, but we always recommend talking with your doctor before starting any new supplement — especially if you're currently taking medication, are pregnant, or are trying to conceive.*
