Vitamins For Female Fertility
Vitamins and minerals are powerful regulators of female fertility and numerous studies have pinpointed specific nutrients that can help women to up the odds of conception. Even a simple multivitamin has been shown to up pregnancy rates.
Recently researchers of natural treatments have becoming increasingly interested in how specific nutrients and vitamins in the follicular fluids - in which the egg matures - affect egg quality and pregnancy rates. IVF provides the perfect situation for analyzing the effects of nutrients as the fluid within the follicle can be analyzed at egg retrieval and compared with IVF success rates. This has been done with melatonin, vitamin D and other nutrients showing that low levels of these -and other nutrients - correlate with lower success rates.
These novel studies give a different view of infertility proving that sometimes nutrient levels, diet and lifestyle choices are huge factors in infertility. At every level, good nutrient levels help to improve the frequency and timing of ovulation, determine egg quality and promote the ideal hormonal secretions for optimum fertility. Here is a list of some of the nutrient superstars that are worth considering in your quest to conceive.
That said, every woman's infertility is different and depending upon your diagnosis, your age and the treatments that you are pursuing you will likely benefit from certain nutrients combinations and not others. Nutritional care for fertility is not a one-size-fits-all magic bullet treatment, it can require some care to pinpoint the nutrients that are best for you, and you should always ask your physician before trying anything new.
* Vitamin D has been shown to have a powerful effect on increasing the odds of IVF success and has been shown to be important for a healthy pregnancy too. Blood tests for 5-hydroxy-vitamin D can readily check your levels so you can supplement effectively.(

* Zinc has been shown to be critical to the rapid development of the egg within the follicle especially with IVF where many eggs are developing at once. Zinc is usually present at higher levels in prenatal vitamins compared to multivitamins, another reason to find a good prenatal vitamin. (

* L-Arginine has been shown in some studies to boost IVF success rates in 'poor responder patients' but other studies have shown poor results at high doses (16 g per day). L-Arginine and has a special place in pre-IVF nutrient protocols at some IVF clinics - at lower doses (2000 mg per day) - and has been proven to increase uterine blood flow. (

* Fish Oil provides DHA which is important for very early neurological development. Taking it pre-conceptually allows you to build up good levels before you conceive. Additionally it's powerful anti-inflammatory effects may help curb conditions such as endometriosis.
* Vitamin C - in small doses of 750 mg a a day - has been shown to correct luteal-phase-defect which is marked by low progesterone in the second half of the menstrual cycle. The treatment boosted progesterone and estrogen levels and resulted in a 25% pregnancy rate within six months. Fertility and Sterility (2003;80:459–61).
* Melatonin has been shown in multiple studies to improve egg quality and almost double IVF success rates when taken for 1-3 months at a dose of 3 mg at night. Melatonin can theoretically elevate thyroid hormone levels so care should be taken if you are borderline hyper-thyroid. (

* DHEA has proven it's worth in improving IVF success and egg quality when taken at a relatively high dose of 75 mg per day and is increasingly being recommended by fertility specialists before IVF. (

* CO Enzyme Q10 - although not backed by human studies - is thought to have a special place in improving egg quality because of it's powerful effect on regenerating the mitochondria - the tiny energy factories of each cell - known to be a factor in age-related infertility. It is recommended by some of the top infertility clinics.
* Myo-Inositol has been the subject of multiple studies for it's ability to help women with PCOS to restore their fertility. Myo-inositol is also known to improve egg quality which is especially valuable for the over 35's. Studies have used a dose of 2 grams twice a day. (

* N-Acetyl Cysteine has shown promise for women with PCOS when given at a dose of 1.2 grams a day alongside Clomid in clomid-resistant women. (

* D-Chiro-Inositol has shown multiple benefits for women with PCOS helping to restore ovulation and combat the other aspects of the syndrome. (

* Alpha-Lipolic Acid is another nutrient that may be helpful to women with PCOS when give as a twice daily controlled release 600 mg tablet. (J Diabetes Sci Technol. 2010 Mar 1;4(2):359-64 Effects of controlled-release alpha lipoic acid in lean, non-diabetic patients with polycystic ovary syndrome. Masharani U, et al.)
* Iron has been shown to reduce the incidence of ovulatory infertility by 50% and is a very common deficiency.
