"A midwife recommended Ovastart to me, and I’ve been taking it regularly for a little over a year. My PCOS symptoms have improved: my periods are lighter and less painful, and my ovaries now appear almost “normal” on the ultrasound."

Is it right for me?

Ovastart is especially recommended if you experience:

  • Irregular or absent cycles
  • Fatigue or low energy
  • Hormonal acne
  • Hair thinning or shedding
  • Excess hair growth
  • Hormonal imbalance symptoms
  • Sugar cravings or blood sugar fluctuations

Why Ovastart works better for these symptoms:
Most supplements only use Myo-Inositol. Ovastart combines Myo + D-Chiro (~4 g) with active folate, B6 P5P, and Zinc Bisglycinate, offering broader support for both hormonal and metabolic pathways.

Benefits & Effectiveness

Two sticks per day. What are the benefits?

  • Supports normal fertility and reproduction thanks to zinc
  • Helps maintain normal testosterone levels in the blood, and supports healthy skin and hair (zinc)
  • Contributes to normal carbohydrate metabolism (zinc)
  • Helps regulate hormonal activity through vitamin B6
  • Helps reduce tiredness and fatigue thanks to vitamins B6 and B9
  • Supports pregnancy preparation, as vitamin B9 contributes to maternal tissue growth during pregnancy

Regulations limit how much detail we can provide about individual ingredient benefits. If you’d like to explore the science further, we encourage you to consult resources such as PubMed.

Ingredients

For 1 stick:
Inositols (2000 mg) – 1981 mg Myo-Inositol + 19 mg D-Chiro-Inositol
Vitamin B9 Quatrefolic® (100 μg – 50% NRV*)
Zinc Bisglycinate (5 mg – 50% NRV*)
Vitamin B6 Pyridoxal-5'-phosphate (1 mg – 70% NRV*)

For 2 sticks:
Inositols (4000 mg) – 3962 mg Myo-Inositol + 38 mg D-Chiro-Inositol
Vitamin B9 Quatrefolic® (200 μg – 100% NRV*)
Zinc Bisglycinate (10 mg – 100% NRV*)
Vitamin B6 Pyridoxal-5'-phosphate (2 mg – 140% NRV*)

*NRV: Nutrient Reference Value

How to use

For optimal use, take 2 sticks per day: one stick just before your first meal of the day and the other just before your last meal — ideally morning and evening.

If you skip breakfast, take your stick with your lunch.

When you notice significant improvement in your symptoms over several months, you can reduce to 1 stick per day only.

If you forget to take your stick at the beginning of your meal, you can perfectly take it before or after the meal. If you experience sensitivity to zinc when starting the product (digestive discomfort, nausea), we recommend beginning with an adaptation phase: take 1 stick per day with your meal for one week.

Compatibility & contraindications

Ovastart is compatible:

  • During IVF or assisted reproduction treatments (PMA/FIV)
  • With treatments for hyperandrogenism
  • With hormonal and non-hormonal contraceptives
  • If you are taking antidiabetic treatments: please consult your doctor
  • During pregnancy and breastfeeding: please consult your doctor

Warnings:
Food supplements should be used as part of a healthy lifestyle and should not be used as substitutes for a varied and balanced diet.
Do not exceed the recommended daily dose.
Keep out of reach of young children.

The ingredients

Inositol

Powerful benefits of this ingredient

Inositol, in its two forms — myo-inositol and D-chiro-inositol — is a nutrient naturally present in the body. These two isomers work together at the cellular level to support overall metabolic balance and help maintain regular menstrual cycles.

Zinc (Zinc Bisglycinate)

Regulates LH and FSH

Zinc is an essential mineral involved in more than 200 enzymatic reactions in the body. It plays a key role in the growth of female reproductive cells, fertility, and pregnancy. Beyond its reproductive functions, zinc is vital for various aspects of cellular metabolism — supporting immunity, protein synthesis, cell signaling and division, maintaining healthy skin and hair, promoting normal glucose metabolism, and protecting cells from oxidative stress.

Vitamin B9

Supports embryonic development

Vitamin B9, in the form of 5-methyltetrahydrofolate (5-MTHF), is the active and directly bioavailable form of folate. It is essential for DNA synthesis and repair, as well as for the methylation of homocysteine — a crucial process for embryonic development and the prevention of neural tube defects. Unlike folic acid, 5-MTHF bypasses MTHFR gene polymorphisms, ensuring optimal effectiveness for everyone.

Unlike folic acid, 5-MTHF bypasses MTHFR gene polymorphisms, ensuring optimal effectiveness for everyone.

Vitamin B6

Promotes regular ovulation

Vitamin B6, in its active form (P5P), is an essential cofactor in amino acid metabolism, neurotransmitter synthesis (including serotonin and dopamine), and hormonal regulation. It supports the production of progesterone — a key hormone during the luteal phase — and helps reduce symptoms of premenstrual syndrome (PMS). Its role is crucial in maintaining the neuroendocrine balance required for regular ovulation and successful implantation.

Answers to your questions

SEE THE FULL FAQ

Why does Ovastart contain both Myo-Inositol and D-Chiro-Inositol

Most inositol supplements on the market only contain Myo-Inositol. But research suggests the two forms work together - Myo-Inositol supports hormonal signalling and ovarian function, while D-Chiro-Inositol plays a role in insulin and metabolic regulation.

Ovastart combines both at a full 4g clinical dose to address both sides of PCOS, something a single-form supplement simply can't do.

Can I take Ovastart if I haven't been formally diagnosed with PCOS?

Yes. If you experience irregular cycles, fatigue, hormonal acne, hair thinning, sugar cravings, or unexplained weight fluctuations, Ovastart may be beneficial.

It is also suitable for women with endometriosis, those trying to conceive, or those approaching perimenopause.

Can I take Ovastart alongside another supplement that already contains Inositol?

We don’t recommend taking Ovastart in addition to other supplements containing myo-inositol or D-chiro-inositol.

Avoid exceeding a total daily intake of 4,000 mg of inositol.

What does inositol powder do for women with PCOS?

Inositol powder - combining Myo-Inositol and D-Chiro-Inositol - helps improve insulin sensitivity, which in turn can lower elevated androgen levels.

This supports more regular menstrual cycles, clearer skin, reduced excess hair growth, and better energy levels. Ovastart delivers the full 4g clinical dose across two daily sticks, targeting both the hormonal and metabolic sides of PCOS.

How should I take inositol powder?

Divide your intake across two doses rather than taking it all at once - this helps maintain consistent levels throughout the day.

With Ovastart, take one stick just before your first meal and one before your last meal. The powder dissolves easily in water, or can simply be placed directly on the tongue with a sip of water. Clinical studies show that a continuous supplementation of at least 3 months is typically required to see a meaningful regulation of menstrual cycles and reduction in androgen levels.

Can I take inositol powder if I haven't been diagnosed with PCOS?

Yes. Inositol is generally safe and well-tolerated regardless of a formal PCOS diagnosis. It may still be beneficial if you experience irregular cycles, hormonal acne, fatigue, sugar cravings, or are trying to conceive. If in doubt, consult your healthcare provider before starting.

Does inositol powder help with stress and mood?

Inositol influences serotonin and dopamine pathways in the brain, which is why it is sometimes used to support emotional wellbeing, reduce anxiety, and ease premenstrual mood changes.

For women with PCOS, where hormonal imbalance often comes with mood fluctuations, this is a meaningful secondary benefit.

What foods are naturally high in inositol - and is diet enough?

Inositol is found naturally in fruits, legumes, whole grains, and nuts.

However, the amounts provided through diet alone are generally far below the 2–4g clinical threshold shown to support hormonal and metabolic health in women with PCOS. That's why a dedicated inositol powder supplement like Ovastart is the most reliable way to reach an effective daily dose.
