Science
A science-first guide to the nutrients inside Libré Daily Vitality ,and why they support conception, egg quality, and hormonal balance.
Most fertility supplement guides hand you a list of brand names and prices. This one is different. Instead of telling you what to buy, we're going to explain why specific nutrients matter for conception — and show you that Libré Daily Vitality Essential already contains all of them, in bioavailable forms, at clinically relevant doses. No fertility-specific label required. Just a smarter daily supplement.
— THE FOUNDATION —
Why what you take — and how it's formulated — determines everything
Fertility is not a single variable. It involves egg quality, hormonal signalling, mitochondrial energy, thyroid function, inflammation, and DNA integrity. No single ingredient fixes all of this — but the right combination of nutrients, in their most bioavailable forms, creates a physiological environment where conception is far more likely to succeed.
The critical error most women make: taking supplements too late (after trying to conceive, rather than 3–6 months before), or using inferior forms of nutrients — like folic acid instead of L-Methylfolate — that their bodies can't efficiently use.
Why form matters |
Up to 40% of women carry an MTHFR gene variant that significantly reduces their ability to convert synthetic folic acid into the active form their body needs. Libré uses L-Methylfolate (Vitamin B9 as L-Methylfolate) — the bioactive form that bypasses this genetic bottleneck entirely. |
— THE INGREDIENTS —
Ingredients inside Libré Daily Vitality that support female fertility
Every nutrient below is present in Libré's Daily Vitality Essential formula. These are not marketing claims — each has a specific, researched mechanism relevant to conception and reproductive health.
Vitamin B9 — L-Methylfolate (as L-Methylfolate)
The most critical pre-conception nutrient
L-Methylfolate is the active, immediately usable form of folate (B9). It is essential for DNA synthesis, cell division, and neural tube development in the embryo. Studies show higher folate intake is linked to improved implantation rates, better oocyte quality in IVF, and lower risk of ovulatory infertility. Crucially, Libré uses L-Methylfolate — not synthetic folic acid — making it effective even for women with MTHFR polymorphisms.

CoQ10 (Coenzyme Q10)
Mitochondrial fuel for egg quality
CoQ10 is a powerful antioxidant naturally produced in the body that declines with age. Eggs require enormous mitochondrial energy to divide correctly — and suboptimal CoQ10 levels are linked to poor egg quality and higher rates of chromosomal abnormalities. A 2020 meta-analysis of 5 RCTs found CoQ10 supplementation doubled clinical pregnancy rates in women undergoing ART (28.8% vs 14.1%). Libré includes CoQ10 to support exactly this mechanism.

Vitamin D3 (Cholecalciferol)
Hormonal regulator and endometrial health
Vitamin D3 functions like a hormone in reproductive tissue. Receptors for vitamin D are found in the ovaries, uterus, and endometrium. Research consistently shows women with sufficient vitamin D levels have better IVF outcomes, improved embryo implantation rates, and more regular ovulatory cycles. Studies indicate that correcting vitamin D deficiency — which is extremely common — may independently improve fertility outcomes.

Omega-3 EPA + DHA (from Algae Extract)
Anti-inflammatory support for ovulation and implantation
Omega-3 fatty acids — EPA and DHA — regulate inflammation throughout the reproductive system, which is a key factor in both ovulation and embryo implantation. Libré uniquely sources its Omega-3s from algae extract (not fish oil), making it vegan-compatible and free of heavy metal contamination risk. Studies show women with higher omega-3 intake are up to 1.5 times more likely to conceive, with particular benefits for women over 35 and those undergoing ART.
Selenium (as Selenomethionine)
Antioxidant protection for eggs and embryos
Selenium is an essential trace mineral and key component of glutathione peroxidase — the body's primary antioxidant enzyme system. It protects egg cells from oxidative damage during development and maturation. Selenomethionine (the form used in Libré) is the most bioavailable form of selenium, with research showing superior absorption compared to inorganic selenite. Abnormal selenium levels are associated with impaired follicular development and higher miscarriage risk.
Zinc (Bisglycinate)
Cell division, DNA repair, and egg development
Zinc is required for virtually every stage of egg maturation, fertilization, and early embryo development. Lower blood zinc levels have been associated with longer time-to-conception in research from the University of Adelaide. Zinc bisglycinate — the form in Libré — is chelated to glycine for superior absorption and gentler gastrointestinal profile compared to zinc sulfate or oxide. Zinc also supports healthy progesterone levels post-ovulation.
Vitamin B12 (Methylcobalamin)
DNA integrity and homocysteine regulation
Vitamin B12 works synergistically with folate in the methylation cycle — the process that controls DNA repair, gene expression, and amino acid metabolism. Methylcobalamin is the active neurological form of B12 and is directly bioavailable, unlike cyanocobalamin which requires conversion. B12 deficiency — common in vegans, vegetarians, and women over 30 — can impair the folate cycle and raise homocysteine, which is associated with recurrent miscarriage and implantation failure.
Iodine (as Potassium Iodide)
Thyroid function — the silent fertility regulator
The thyroid is a master hormonal regulator of the menstrual cycle, ovulation, and early pregnancy maintenance. Even subclinical hypothyroidism — often caused by iodine insufficiency — can prevent ovulation and dramatically increase miscarriage risk. Libré includes iodine as potassium iodide to ensure adequate thyroid support, particularly important for women avoiding iodized salt or dairy.
Magnesium (as Magnesium Bisglycinate)
Stress, sleep, and hormonal balance
Magnesium is involved in over 300 enzymatic reactions, including those governing sex hormone production and insulin sensitivity. Chronic magnesium deficiency — extremely common in modern diets — is associated with elevated cortisol, disrupted sleep, and impaired progesterone production. Magnesium bisglycinate, the form in Libré, crosses the blood-brain barrier and is highly bioavailable without the laxative effect of cheaper forms like magnesium oxide.
Vitamin C (L-Ascorbic Acid)
Antioxidant and progesterone support
Vitamin C is concentrated in the corpus luteum — the structure that forms after ovulation and produces progesterone. Adequate vitamin C supports robust progesterone levels in the luteal phase, which is critical for embryo implantation and early pregnancy maintenance. As a potent antioxidant, it also protects follicular fluid from oxidative stress during egg development.
— TIMING —
When to start — the 90-day fertility window
Egg maturation (folliculogenesis) takes approximately 90 days from primordial follicle recruitment to ovulation. This means the nutritional environment you create today directly influences the quality of eggs that will be available for conception three months from now.
The 90-day rule |
Fertility specialists recommend beginning a comprehensive supplement protocol at least 3 months before trying to conceive. This allows nutrients like CoQ10, folate, and selenium to accumulate in follicular fluid and exert their effects on oocyte development. Starting Libré Daily Vitality now means your eggs — and your body — will be better prepared when it matters most. |
Libré Daily Vitality is not a fertility supplement — it's a daily women's health formula that happens to contain every fertility-relevant nutrient in its optimal bioavailable form. That's the point: rather than stacking a pile of separate supplements, women get comprehensive support from a single daily habit.

Common questions about fertility supplements
Q: Do I need a separate fertility supplement if I take Libré?
A: For most women who are healthy and trying to conceive, Libré Daily Vitality provides the foundational fertility-relevant nutrients in their optimal forms. It is not marketed as a fertility supplement, but it contains L-Methylfolate, CoQ10, Vitamin D3, Omega-3s, Selenium, Zinc, B12, and Iodine — the exact stack fertility specialists recommend. Always consult your healthcare provider for personalised advice.
Q: Why L-Methylfolate instead of folic acid?
A: Up to 40% of women have MTHFR gene variants that impair their ability to convert synthetic folic acid into the active L-Methylfolate their body actually uses. Libré skips that step entirely by providing the active form directly, ensuring efficacy regardless of your genetic profile.
Q: How long before trying to conceive should I start?
A: At least 90 days (3 months), ideally 6 months. Egg maturation takes roughly 90 days, so the nutrients you take today influence the eggs ovulated in three months. Folate, CoQ10, and selenium all require time to build up to therapeutically relevant levels in follicular fluid.
Q: Is the algae-derived Omega-3 in Libré as effective as fish oil?
A: Yes. DHA and EPA from algae are chemically identical to those from fish — fish get their omega-3s from algae in the first place. Algae-derived omega-3s are also free from heavy metal contamination risk and suitable for vegans and pescatarians alike.
