Frequently Asked Questions

How long until I see results?+
Most women notice improvements in energy and mood within the first 2–4 weeks. Cycle regularity typically follows at weeks 4–8. Fertility outcomes — like confirmed ovulation and regular cycle length — generally show meaningful improvement between months 2 and 4 with consistent daily use. Give it at least one full cycle before evaluating.
Why does the 40:1 ratio matter so much?+
Your ovarian follicular fluid naturally contains myo-inositol and d-chiro inositol at a 40:1 ratio. When that ratio is off — which happens with PCOS and insulin resistance — ovulation gets disrupted. Supplementing at 40:1 helps restore the balance your body is trying to maintain. Most inositol products use myo-inositol alone or use an arbitrary ratio. We use the one that matches the research.
I don't have PCOS — will this still help me?+
Yes. Inositol supports healthy ovulation and hormonal balance in all women — not just those with a PCOS diagnosis. Many women with irregular cycles, luteal phase defects, or unexplained fertility challenges have benefited from inositol supplementation. If you're trying to conceive or simply want better cycle health, the formula works regardless of diagnosis.
Is it safe to take while pregnant or trying to conceive?+
Inositol is one of the most studied supplements in reproductive medicine and has a strong safety profile in both preconception and early pregnancy. It's widely used in fertility clinics. That said, always check with your OB or midwife before starting any new supplement during pregnancy — they know your specific situation best.
Can I take this alongside other supplements or medications?+
Inositol is generally well-tolerated alongside prenatal vitamins, folate, CoQ10, and most common supplements. If you're taking metformin or medications for insulin resistance, let your doctor know — inositol has similar mechanisms and your provider may want to adjust dosing. For most women it's a clean, safe addition to their routine.
How do I take it?+
Mix one scoop into 8–12 oz of cold water, juice, or a smoothie once daily. Morning with breakfast works best for most women. Consistency is everything with inositol — it builds up in your system over time, so daily use matters more than timing.
What if it doesn't work for me?+
You're covered by a full 30-day money-back guarantee. If you don't notice a meaningful difference in your cycle or how you feel, email us and we'll refund you completely — no questions asked.

What Our Customers Are Saying

Thousands of women have made Terva Labs part of their daily routine. Here's what they experienced.

★★★★★

"My cycle came back after 11 months"

I have PCOS and my period had been completely absent for almost a year. My OB mentioned inositol and I found Terva Labs. I was skeptical but within 6 weeks I had my first real period in nearly a year. I cried. My husband cried. I'm now on my third regular cycle in a row and we're actively trying. I tell every woman I know about this.

"The Strawberry Acai flavor is actually unreal"

I'll be honest — I bought this mostly because the flavor looked good and I was tired of choking down chalky pills. The Strawberry Acai mixed into sparkling water is genuinely something I look forward to every morning. But then around week 5 I realized my mood swings had basically disappeared and I'd had two normal cycles back to back. The taste got me here, the results are keeping me here.

"My fertility specialist recommended the exact ratio in this"

I've been seeing a reproductive endocrinologist for 14 months. She specifically told me to look for myo and d-chiro inositol at a 40:1 ratio. I researched every brand I could find and Terva Labs was the only one that got it right AND came as a powder I could actually stomach. My LH surge came back on cycle day 14 for the first time in over a year. My RE was genuinely pleased at our last appointment.

"Tried the cheap inositol capsules first — huge difference"

I'll be real — I bought a generic myo-inositol powder from Amazon first because I didn't want to spend more. Took it for two months, noticed basically nothing. Then I read about the 40:1 ratio and why it matters and understood what I'd been missing. Switched to Terva Labs. Within three weeks my skin was clearer and I could feel my cycle starting to normalize. The research actually matters. You get what you pay for.

"My husband noticed the difference before I did"

About three weeks in my husband said "you seem different lately — in a good way." Less irritable, sleeping better, more energy in the evenings. I hadn't even connected it to the supplement yet. Then I realized I hadn't had a single mood swing that week and my bloating was almost completely gone. Month two my cycle came in at 29 days — first time in three years it's been under 35. He bought me a three-month bundle without me asking.

"30 days in and my acne is almost completely gone"

I've had hormonal chin and jaw acne since I was 22. Tried everything — spironolactone, every skincare routine you can imagine. My dermatologist finally mentioned that hormonal acne often signals androgen excess and suggested looking into inositol. One month on Terva Labs and my skin is the clearest it's been in six years. The Strawberry Acai mixed into my morning smoothie doesn't even taste like a supplement. Genuinely obsessed.
