What You Need To Know About The Link Between Vitamin D and Fertility
Since the early 2000s, a pandemic linked to vitamin D and fertility has spread across all ethnic groups in the United States. Vitamin D is often referred to as the “sunshine vitamin” since it is generated in the skin in reaction to sun exposure and may also be obtained via diet and supplements.
But, there was a roughly 2-fold increase in the likelihood of vitamin D deficiency from 1994 to 2004. Since then, many scientific studies have been conducted that link vitamin D to various health advantages, one being improved fertility, and better, overall pregnancies for women who are attempting to conceive.
You may be at risk of vitamin D insufficiency if you avoid the sun, have milk allergies, or maintain a consistent vegan diet. We’ll explain the effects of low vitamin D, how vitamin D helps fertility, and the recommended doses of vitamin D.
Effects Of Low Vitamin D
Effects of low vitamin D have been linked to the following:
- Increased risk of mortality from cardiovascular disease
- Cognitive impairment in elderly people
- Severe asthma in children
- Different types of cancer
- Rickets-like condition, where bone tissue does not mineralize correctly causing bones to become soft and abnormalities to occur.
More studies indicate the critical significance of vitamin D, including the prevention of various diseases like type 1 and type 2 diabetes, hypertension, glucose intolerance, and multiple sclerosis.
The Relationship Between Vitamin D and Fertility
Vitamin D has been suggested as a hidden factor in the success of solving fertility issues.While data on the direct relationship between vitamin D and fertility is inconclusive, many studies have shown that vitamin D blood levels of 30 ng/mL or above are associated with increased pregnancy rates.
Recently, a meta-analysis of many studies has shown that vitamin D blood levels are related to live birth rates in women receiving reproductive treatments. Those with higher levels of vitamin D (30 ng/mL or more) had higher live birth rates than women with lower levels (under 30 ng/mL).
How Does Vitamin D Help Fertility?
Vitamin D (calcitriol) in its active state actually provides a variety of functions in female reproduction.
Calcitriol, when bound to its receptor, exerts control over the genes responsible for oestrogen production. The uterine lining generates calcitriol in reaction to the embryo entering the uterine cavity soon before implantation. Calcitriol is a transcription factor that regulates many genes involved in embryo implantation. After a woman gets pregnant, her uterus and placenta continue to produce calcitriol, which aids in the organization of immune cells in the uterus, allowing infections to be treated without endangering the foetus. Vitamin D deficiency has been linked to a number of pregnancy problems, including gestational hypertension and diabetes.
According to recent research, women with greater vitamin D levels were substantially more likely to achieve pregnancy through IVF than women with lower vitamin D levels. Thus, it is beneficial for both mom and baby to continue taking vitamin D supplements when pregnant. Vitamin D supplementation of 2,000–4,000 IU per day has been proven to be safe and effective in maintaining a normal vitamin D level in pregnant women and avoiding vitamin D insufficiency in infants.
How Can You Tackle Vitamin D Deficiency?
To improve bone health, the Institute of Medicine increased the recommended dietary intake (RDA) of vitamin D to 600 international units (IU) for all people between 1 and 70 years old and to 800 IU for persons over age 70. Additionally, the safe upper limit was increased to 4,000 IU.
Regardless of the possible link between vitamin D and fertility, patients should be educated on the need of adequate vitamin D intake for general health benefits, which include bone health, pregnancy health, and risk reduction for chronic illness.
