We’ve worked with fertility doctors to develop vitamins good for fertility . Thanks to our research-intensive formulas, we have favored nutrients that ensure maximum absorption.
+fertiwomen Inositol contains optimal doses of 15 premium essential nutrients, including Myo-Inositol, active folate Quatrefolic® (5-MTHF), Coenzyme Q10, selenium, chelated iron bisglycinate, and L-Arginine .
Our +fertiwomen range uses only pure Myo-Inositol in the form that has been most extensively studied and proven to be most effective for female fertility (rather than D-chiro-inositol alone). This form, which occurs naturally in the body, is immediately active and acts directly on insulin sensitivity and egg quality, even in cases of PCOS or insulin resistance.
Myo-Inositol is relevant for both women and men. Numerous independent studies show that it improves egg maturation, increases spontaneous ovulation rates, and improves sperm parameters (motility and morphology) in men. It is now considered the number one “natural hormone regulator” for fertility.
Higher intakes of Myo-Inositol have been correlated with: – restored ovulation in 65-88% of women with PCOS – improved egg and embryo quality in IVF – a significantly higher clinical pregnancy rate (up to +20% in combination with folic acid) – a shorter time to conception and a reduced risk of miscarriage¹²
Myo-Inositol contributes to normal insulin metabolism and ovarian signaling.

Vitamin C is an essential antioxidant for men and women who want to become parents. In women, this vitamin increases hormone levels and helps regulate menstruation.
Studies have also shown that taking vitamin C is effective in stimulating fertility.
Vitamin C increases iron absorption.
Vitamin C helps protect cells against oxidative stress.
Vitamin C contributes to the normal functioning of the immune system.

Recent scientific studies confirm that coenzyme Q10 supplementation clinically significantly improves fertility parameters in women and men (egg quality and maturity, sperm motility and vitality).
In +fertiwomen and +fertimen, we have selected the ubiquinol form (the reduced and active form of CoQ10) because it can be used directly by the body, is much better absorbed than traditional ubiquinone and acts more quickly as a powerful antioxidant. Ubiquinol protects oocytes from daily oxidative stress while optimising energy production in the mitochondria of reproductive cells – two essential mechanisms for improving egg quality and promoting natural conception.
The dose has been determined by our medical formulators based on current scientific data: it offers optimal, safe and effective support for women trying to conceive, without the risk of side effects or overdose. Much higher doses (200 to 600 mg) are generally only justified in specific situations (IVF, age > 38, confirmed low ovarian reserve) and should always be preceded by a medical diagnosis.
Arginine is one of the 20 amino acids that make up our proteins.
Taking L-Arginine is beneficial for both male and female fertility. It is often recommended for couples trying to conceive. It helps the body produce nitric oxide, which promotes blood flow to the genitals and ovaries.
L-Carnitine is present in very high concentrations in follicular fluid and mature oocytes, where it plays an essential role in transporting fatty acids to the mitochondria to produce the energy needed for oocyte maturation and early embryonic development. It also protects oocytes from oxidative stress by acting as a natural antioxidant, thereby reducing oocyte DNA fragmentation and improving egg quality.
Recent meta-analyses and trials confirm these effects: after 2 to 3 months of L-carnitine supplementation, the oocyte maturation rate increases by 10 to 25%, the fertilisation rate by 8 to 18%, and the rate of good-quality blastocysts by 12 to 30% compared to placebo, with particularly marked benefits in women over 35 and in cases of poor ovarian response.¹
That is why our medical formulators have included L-carnitine in +fertiwomen at the optimal dose: safe, effective daily support with no side effects, working in perfect synergy with ubiquinol and the other active ingredients in the formula to maximise your chances of natural conception.

An increased intake of vitamin E can lead to a significant increase in fertility in both men and women.
Vitamin E helps protect cells against oxidative stress.
+ferti has been designed with ferrous bisglycinate, which has been shown to be easily absorbed, causing fewer side effects and less likely to block the absorption of vitamin E and calcium.
Iron plays a role in the cell division process.
While most prenatal vitamin supplements use vitamin D from an animal source (lamb’s wool), our +ferti range has been designed with vitamin D carefully extracted from seaweed to provide an easily absorbable vegan form of vitamin D3. Made with Vita-algae D, a sustainable, vegan form of cholecalciferol (vitamin D3).
Vitamin D plays a role in the cell division process.
Calcium and vitamin D are necessary for normal growth and bone development in children.
Selenium contributes to normal spermatogenesis.
Selenium helps protect cells against oxidative stress.
Selenium contributes to the normal functioning of the immune system.

Our +ferti range uses only Quatrefolic®, the most bioavailable patented form of 5-MTHF folate on the market (rather than synthetic folic acid). This active form can be used immediately by the body, even in cases of MTHFR mutation. Read our article to find out more.
Folic acid is important for both women and men. The results of two independent studies suggest that high doses of supplemental folate can help the body reduce the negative effects of environmental pollutants on fertility. It is also described as the vitamin of life.
Higher intakes of 5-MTHF Quatrefolic® have been linked to a reduced risk of infertility, shorter time to pregnancy, lower risk of miscarriage and better fertility treatment outcomes.¹
Folate plays a role in the process of cell division.

Answers to your most frequently asked questions
It is generally recommended that women of childbearing age take a prenatal food supplement if they are not trying to prevent pregnancy, if they are planning a pregnancy in the near future, if they are trying to get pregnant, if they are pregnant, or if they are breastfeeding.
This recommendation stems from the fact that up to 45% of pregnancies are unintended. Some of the most important growth for your baby occurs in the first month of pregnancy, often before you even know you’re pregnant. This is why obstetric gynaecologists recommend that you start taking a prenatal vitamin several months before you actively try to conceive.
For the entire preconception period, we recommend our best fertility supplements for women — +ferti food supplement, which contains all the nutrients you need to prepare for and start pregnancy. Once your pregnancy is confirmed, you can take our +mum food supplement.
Our dietary supplement has been carefully developed based on studies that reflect the latest research in fertility and conception. The development of the formula was led by our certified gynaecologist and obstetrician, Dr Alexandra Fischer-Stoca.
We’ve worked with fertility doctors to develop a fertility vitamin for females. Thanks to our research-intensive formulas, we have favoured nutrients that ensure maximum absorption.
+fertiwomen contains optimal doses of 15 high-quality essential nutrients, including folic acid, Coenzyme 10, selenium, iron and arginine.
+ferti capsules are formulated with premium, highly bioavailable ingredients for maximum effectiveness: active folate Quatrefolic® (5-MTHF), stomach-friendly ferrous bisglycinate chelated iron, and 100% vegan Vita-algae® vitamin D3. A premium selection designed to safely support your fertility.
Quatrefolic® is the patented form of 5-MTHF folate, the only form that is biologically active and directly usable by the body. Unlike conventional folic acid, it does not require conversion by the MTHFR enzyme, even in people with the MTHFR genetic mutation (up to 25% of the population, particularly the 677TT variant).
With Quatrefolic®, you are guaranteed maximum bioavailability, rapid and complete absorption, and optimal efficacy, whether or not you have the MTHFR mutation.
While most dietary supplements use vitamin D from lamb’s wool, our vitamin D is carefully extracted from seaweed to provide an easily absorbable vegan form of vitamin D3.
Every day: take 2 capsules a day, either in a single dose or one in the morning and one in the evening.
It’s up to you! We find it easier to remember when you take them all at once. But some people prefer to take one in the morning and the rest at bedtime.
Above all, we believe in confidentiality. Your Plusbaby supplements are delivered in a plain envelope, with no reference to Plusbaby. The envelope is small enough to fit in a letterbox slot, and no signature is required.

Yes, absolutely. Our +fertiwomen Inositol capsules can be taken with milk, yoghurt or any other food without any problem.
Yes, our formulas are designed for continuous daily use, even over several years, without the need for breaks.
We recommend starting the best female fertility supplement +Fertiwoman Inositol and +fertimen at least 3 months, but ideally 6 months, before the start of IVF or ART. This allows time for the nutrients (such as coenzyme Q10 and amino acids) to improve the quality of the eggs and sperm, enhancing motility and protecting against oxidative damage to maximise the chances of success.
No, we do not recommend taking them at the same time. +fertiwomen Inositol, the fertility vitamin for women, is specially formulated to optimise fertility and support the desire to become pregnant: it should be taken as soon as you start trying for a baby. Once pregnancy is confirmed (positive test), it is best to stop taking +fertiwomen Inositol and switch to +mum, which provides the specific nutrients necessary for the baby’s proper development (particularly iron bisglycinate).
This change ensures that you receive the right care at every stage, without any unnecessary duplication. If you have any doubts or if there is a very short cycle between trying to conceive and conception, simply ask your doctor or midwife for advice.
Yes, our products are generally compatible with hormonal treatments such as Clomid, Letrozole, Gonal or Menopur, as they are 100% natural and vegan, with no known interactions. However, we advise you to consult your doctor or best gynaecologist for personalised advice, especially if you are following a specific assisted reproductive technology (ART) protocol.
Yes, you can open the +fertiwomen Inositol capsules and mix the powder into yoghurt, compote or a smoothie. This makes it easier to take for those who have difficulty swallowing +fertiwomen Inositol capsules. Just make sure you consume the mixture immediately to preserve the nutrients, and follow the recommended dosage (2 capsules per day).
Do Plusbaby products contain gluten, lactose or soya?
No, our Plusbaby products are free from gluten, lactose and soya. They are 100% vegan, formulated with natural ingredients that are highly bioavailable, without additives or preservatives, to suit all diets and avoid common intolerances.
It is not mandatory to take them with meals, but we strongly recommend it for better absorption of nutrients (such as fat-soluble vitamins) and optimal digestive comfort. It is possible to take them on an empty stomach, but drink a large glass of water to avoid any discomfort.
