The Vitamin D testosterone relationship has been clearly established before-it absolutely benefits testosterone levels and helps when it comes to fertility and sperm motility. The vitamin isn’t just for T though, as it’s considered an “overall health” vitamin.



What Really Is Vitamin D?

Despite the word "vitamin" in its name, vitamin D is technically a prohormone. This sets it apart from other vitamins because it can be produced by the body (though, to be clear, you can still get it from food).

Known as the "sunshine vitamin", vitamin D is made by the body (the skin to be precise) following a period of sun exposure, especially in the morning.

It’s a fat-soluble vitamin, meaning it is stored in the fatty tissues and in the liver. Unlike water-soluble vitamins, vitamin D residue takes longer to be eliminated from the body because of its fat-soluble nature.

The vitamin comes in two common types: D3 or cholecalciferol and D2 or ergocalciferol. D3 is mainly produced by the skin, while D2 is found in food and in supplements (though D3 is also commonly found these days as well)

The top benefits of taking vitamin D include maintaining bone health and density, and regulating insulin levels. It also makes it easier for you to increase your muscle mass.


Serum Vitamin D and your Testosterone levels are intricately linked; low Vitamin D equates to low T.

By using pregnenolone cream or pregnenolone supplements, the levels of the compound in the body increases, and this brings about various benefits such as fatigue relief, and delay of the aging process.

A Testosterone Advantage

As revealed in a study, taking vitamin D regularly for a year can result in up to a 25% increase in testosterone levels. Study participants were divided into two groups;

The first group received 3,332 IU (international units) of Vitamin D daily. On the other hand, the second group received a double-blind placebo-controlled dose (meaning nada).

Results showed that year-long supplementation had boosted calcifediol concentrations in the body. Calcifediol is a prehormone that the liver produces when processing vitamin D3.

Like most of our readers, you’re probably more interested in ways to increase testosterone. Well, these numbers might just satisfy your curiosity.

  • Total testosterone levels increased from 10.7 ± 3.9 nmol/L to 13.4 ± 4.7 nmol/L
  • Bioactive testosterone levels increased from 5.21 ± 1.87 nmol/L to 6.25 ± 2.01 nmol/L
  • Free testosterone levels increased from 0.222 ± 0.080 nmol/L to 0.267 ± 0.087 nmol/L

Another study links Vitamin D with the stimulation of Leydig cells under the influence of luteinizing hormone (LH), resulting in enhanced testosterone production. Leydig cells are known to be “T-factories” and are found in the testes.

On Hormones and Fertility

Given all these, it isn’t surprising at all that vitamin D appears to be involved in male steroidogenesis by significantly stimulating the production of testosterone.

Steroidogenesis is the process of producing androgens (or other steroid hormones), which help with the development of male sexual organs (during puberty) as well as secondary sex characteristics.

The testes, prostate glands, and spermatozoa (mature sperm cells) all have vitamin D receptors (VDRs) that specifically receive vitamin D in the male reproductive tract.

Vitamin D also contributes to sperm quality, with higher blood levels ofthe vitamin positively associated with enhanced sperm motility. This suggests a role for vitamin D in maintaining reproductive health.


Shields You from Disease

Aside from getting higher testosterone levels, improving your hormonal balance, and making you more virile, vitamin D supplementation lowers your risk of developing certain illnesses.

Higher blood Vitamin D levels is associated with reduced incidence of hypogonadism , as wasmade clear in a cross-sectional study conducted on European middle-aged men ranging in age between 40-79 years old.

Another study foundthat vitamin D inhibits the growth of prostatic epithelial cells, preventing prostate cancer. Research also suggests that vitamin D supplementation lowers the risk for both Alzheimer’s disease and dementia.


About Sources and Choices

Now that you’re aware of the benefits that this vitamin provides, you might be thinking of one particular question—what are the best ways of getting more vitamin D?

Food

Not many natural food sources contain the vitamin. Still, if you want to meet your daily requirements through dietary means, you should probably consider these:

Sun Exposure

The National Institutes of Health recommends 5 to 30 minutes of sun exposure, ideally between the hours of 10 AM to 3 PM. This allows the body to produce a sufficient amount of vitamin D.

Supplements

Vitamin D can also be taken in supplement form. As you’d expect, it isn’t hard to find supplements that either contain just vitamin D or have it combined with micronutrients and other testosterone boosters.

Our favorite dietary supplement for Vitamin D is made with the purest ingredients and doesn’t contain gluten. It even has a metered dispenser that allows for easy dosing.


Getting the Correct Dosage

According to the National Institutes of Health, 600 IU or 15 mcg of vitamin D is recommended for men aged 18-70 years old, while 800 UI or 20 mcg is recommended for men 70 years and older.

Because vitamin D requirements vary by age and health status, it would be best to visit your doctor or pharmacist before taking vitamin D supplements or loading up on food rich in the prohormone in order to establish your optimal dosage.

Getting too much of it may cause side effects such as insomnia, stomachache, and in some cases, fatigue and toxicity. Vitamin D toxicity symptoms include anorexia, weight loss, polyuria, and heart arrhythmias.

In addition, don’t ever forget that overexposure to sunlight will increase your chances of developing skin cancer. So, be sure to stay within the prescribed exposure durations.


Not Just Another Vitamin

A good vitamin D status is tied to healthy testosterone levels. By getting enough of the vitamin, you’ll enjoy improved masculinity and enhanced virility—all while safeguarding yourself from many health maladies.

With lots of studies proving the benefitsof ensuring you meet your Vitamin D requirements, there is no reason why you shouldn’t pay more attention to it.
