Prolog Preconception Formula






Ultimate Preconception Formula is a nutritional supplement that may enhance female fertility. This product has been developed to meet the nutritional requirements associated with successful conception and reproductive health and these levels of specific, fertility-promoting supplements would be difficult to achieve through diet alone.

This product is designed for the female who may have impaired egg quality. It is also for the couple where at least one partner is greater than 35 years of age, as well as those having difficulty conceiving, undergoing fertility treatments by inseminations or IVF, or with unexplained infertility.

Partial Ingredient List:

Vitamins A, C, E: Help protect oocytes and other cells from oxidative stress and cellular damage.

Selenium: A component of enzymes involved in antioxidant protection and thyroid hormone metabolism. Selenium plays a role in preventing lipid peroxidation and membrane damage.

Ubiquinol: Coenzyme Q (CoQ 10) is mainly known for its role as a proton and electron carrier in mitochondria (the cell’s power plant”) and is also an antioxidant, ubiquitous in cell membranes.

Lycopene, Grape seed extract, Quercetin: Potent antioxidants that promote normal cell development and guard against oxygen radicals.

B vitamins: These key nutrients help the formation and maturation of egg cells as well as pregnancy outcome.

Folate: As a coenzyme, folate is essential for DNA synthesis and cell division as well as amino acid metabolism and cell maturation. Folate is crucial for normal embryonic development. When taken prior to and during the first thirty days of pregnancy, adequate amounts of folic acid may reduce the incidence of neural tube defects such as spina bifida, myelomeningocele and anencephaly. Folate may also help prevent premature deliveries, low birth weight babies, and congenital defects cleft lip and palate.

Iron, Magnesium, Zinc and Trace minerals: Help red blood cell and other cell growth and function.

The Scientific Basis:

Generally, 40% of the couples with impaired fertility have a female factor as primary cause. There is increasing evidence that preconceptional nutritional status plays an important role in fertility and long-term health of the offspring and dietary interventions and nutritional supplements may counteract the deleterious effects of oxidative stress on female fertility and oocyte (egg) health.

During normal metabolism, reactive oxygen species (ROS) are generated on an ongoing basis, either by external or internal causes and ROS are critical for many processes in the human body, including certain intracellular signaling pathways. However, when there is an imbalance between oxidants and buffering antioxidants there is oxidative stress. Oxidative stress can negatively impact fertility by directly and indirectly affecting multiple processes in the female reproductive system. ROS, or oxygen radicals, such as hydrogen peroxides, superoxide anions, singlet oxygen and hydroxyl radicals, are the natural byproducts of oxygen metabolism. Oxygen radicals, however, are unstable, toxic molecules that contain one unpaired electron. These unpaired electrons make free radicals highly reactive such that they can react with lipids, amino acids and DNA/RNA in their vicinity. One free radical can spark a chain reaction, instantly causing a cascade of new free radicals. In the normal state, the follicular fluid contains antioxidants which both negate the effects of these ROS and which protect the egg cells from oxidative damage. However, during times of physical or environmental stress, the concentration of ROS can increase markedly, leading to extensive egg DNA damage. It has been suggested that in addition to damaging oocytes within developing follicles, oxidative stress may affect oocyte maturation, fertilization and embryo development and may be involved in the planned cell damage and death (apoptosis) of oocytes associated with the age-related decline in female fertility.

Coenzyme Q10, ubiquinone, present in circulating lipoproteins is a potent antioxidant. At the cellular level it can increase energy production and affect gene expression. Observational studies have suggested that supplementation may improve pregnancy rates in women greater than 35 years of age. A recent clinical study that was not sufficiently powered to achieve statistical meaning, involving Coenzyme Q10 in the IVF setting revealed a higher clinical pregnancy rate in the Coenzyme Q10 group (33%) versus the control group (26.7%). In addition, the rate of aneuploidy (abnormal chromosome copy number in cells) in embryos was higher in the control group (62.8%) relative to the Coenzyme Q10 group (46.5%).

Observational studies have shown oxidative stress markers in high concentrations in the follicular fluid and serum of women with infertility; however, there can be no cause and effect relationship confirmed from such studies. Studies of antioxidants in female infertility have been reviewed in a Cochrane review published in 2013. The quality of evidence was “very low” to “low” due to methodologic problems with the reviewed studies. However, no evidence revealed a difference in adverse outcomes between antioxidant groups and control groups. It must be further noted that treatment with nutritional supplements with or without standard infertility treatments (ovulation induction, IVF) has not been subject to statistically robust prospective, randomized clinical trials.

Some supplements may have side effects, may affect underlying medical conditions, or may interact with prescription medications. Therefore, Prolog Health vitamins and supplements are recommended for use under the direct supervision of your physician.
