does vitamin d increase testosterone

Vitamin D plays a very important role in your overall health, but it’s often a difficult vitamin to get enough of naturally.

However, some studies show a strong link between high vitamin D levels and high testosterone levels, making it an essential vitamin for men of all ages.

Quick FAQs

Vitamin D is a vitamin that helps to improve different functions of the body including the immune system and the cardiovascular system.

Studies have found a correlation between high amounts of vitamin D in the blood and high amounts of testosterone.

Men should have at least 600 IU of Vitamin D a day. For supplementation purposes, a man should have 1,000 to 4,000 IU a day.

This guide will go over the benefits of vitamin D, how to get the most from it, and other ways to combat low testosterone.

What is Vitamin D, and Why is it Important?

Vitamin D is an essential vitamin that helps to:

  • Improve longevity
  • Reduce depression
  • Improve the immune system
  • Regulate hormones
  • Possibly prevent certain cancers
  • Improve heart health
  • Improve the cardiovascular system
  • And much more

It's also very easy to be deficient in since it’s not as abundant in foods as most vitamins are.

Some foods contain a high amount of it, such as:

  • Fortified milk
  • Cheese
  • Salmon
  • Fatty fish
  • Certain mushrooms

Vitamin D is also produced in high quantities when you’re exposed to sunlight.

Of course, overexposure to sunlight has its own risks, from sunburn to skin cancers. 

Some people also live in areas that have less sunlight throughout the year, making deficiencies quite common.

The downsides of a vitamin D deficiency are vast.

Everything from depression to insomnia and even low testosterone can be signs of a vitamin D deficiency.

Many men may experience these symptoms without realizing the true culprit.

Does Vitamin D Increase Testosterone?

Studies show that high amounts of vitamin D in the blood also correlate with high amounts of testosterone.

Even though there's a correlation between vitamin D and testosterone, does vitamin D boost testosterone as well? 

In some studies, they have found that increasing the supplementation of vitamin D can increase overall testosterone levels in men.

So how much vitamin D do men need for testosterone support?

The answer likely varies depending on the man's age and whether he's deficient in the vitamin. 

The average recommendation is 600 IU per day as a starting supplement, although doses starting at 1,000 IU are also common.

Along with increasing testosterone, vitamin D comes with many profound mental and physical benefits.

It can help increase bone density and lessen the risk of depression, making it a worthwhile supplement for most men.

Low Testosterone Symptoms

Some common signs and symptoms of low testosterone include:

  • A reduced libido
  • Erectile dysfunction
  • Pubic hair loss
  • Loss of body hair
  • Hot flashes
  • Shrinking testicles
  • Sudden weight gain
  • Insomnia
  • Fatigue
  • Loss of muscle mass
  • Loss of bone mineral density and bone strength

Ways to Boost Testosterone

Aside from increasing vitamin D, there are other natural and simple ways that can potentially increase testosterone levels.

Some simple at-home steps include:

  • Lifting weights
  • Getting enough sleep
  • Eating a healthy and well-rounded diet
  • Losing weight (especially if obese)
  • Limiting or avoiding tobacco and alcohol

Testosterone Replacement Therapy

If a doctor determines a patient has low testosterone, they may recommend testosterone replacement therapy or TRT for short.

TRT can help to:

  • Increase libido
  • Improve energy levels
  • Improve bone density
  • Strengthen muscles
  • Improve the cardiovascular system

As with any hormone therapy, there are some risks involved, including:

  • Acne
  • Weight gain
  • Prostate growth and if a nascent (sleeping) prostate cancer is present, TRT can stimulate its growth (TRT does not cause prostate cancer)
  • Blood clots

Although TRT can only be done with a doctor’s approval, it may prove to be a worthwhile treatment for those suffering from severely low testosterone.

While many of the tips on this list may help, TRT is one of the few concrete ways of quickly increasing testosterone in a controlled medical setting.

Foods to Boost Testosterone Levels

If TRT sounds like too much, there are a number of foods available that have been suggested to increase testosterone.

These are often fatty foods that are rich in vitamin D and other essential nutrients like magnesium and zinc.

Some of these foods include:

  • Salmon
  • Tuna
  • Kale
  • Spinach
  • Raw cocoa
  • Oysters
  • Shrimp
  • Steak


Supplements like vitamin D are great for potentially boosting testosterone, and some, like ashwagandha, show some promising results.

Fenugreek is another supplement that also may naturally increase testosterone in some men.

Products like ڤَيتا فلَكس can help to increase overall health by providing essential nutrients that can aid the cardiovascular system and improve libido.

How Much Vitamin D Does a Man Need?

Vitamin D is measured in international units or IU.

What is the daily recommended dose of vitamin D for a man?

An average man should have at least 600 IU per day, although, for supplementation purposes, many recommend between 1,000 to 4,000 IU per day.

4,000 IU is considered to be the maximum anyone should take per day.

Talk to your doctor if you feel you need a dosage beyond the 4000 IU per day recommended.

Symptoms of Vitamin D Deficiency

Vitamin D deficiencies are quite common since many people don’t supplement it, eat foods rich in it, or get enough sunshine to produce it naturally.

Some of the most common vitamin D deficiency symptoms include:

  • Low testosterone
  • Insomnia
  • Fatigue
  • Hair loss
  • Depression
  • Aches and pains
  • A weakened immune system
  • Appetite loss
  • Muscle weakness

Can You Overdose on Vitamin D?

It is possible to overdose on vitamin D, although the threshold is different for most people depending on age, gender, height, and weight, plus other individual factors.

The recommended max dosage is 4,000 IU per day. This should only be considered if your Vitamin D levels are severely below normal.

The overdose symptoms generally start after higher doses or long-term high dosage supplementation.

It’s important to supplement slowly in the beginning, and only go on to higher doses at a doctor’s recommendation.

Symptoms of Vitamin D Overdose

Some common symptoms of a vitamin D overdose include:

  • Nausea
  • Vomiting
  • Fatigue
  • Weakness
  • Frequent urination
  • Kidney pain
  • Calcium stones

Taking high doses of vitamin D for a long time may also lead to kidney problems along with other health complications.

Always stay within the recommended dose structure, and only take high doses if approved by a professional.


Vitamin D appears to have some health benefits for sexual health and overall well-being.

Many studies have found a correlation between high vitamin D levels and high testosterone levels, which is helpful in the fight against low testosterone.

If anyone is suffering from low testosterone, it may be worthwhile to supplement with vitamin D to raise testosterone.

It’s also beneficial to try eating foods that are rich in Vitamin D or getting more sunshine throughout the day (while still wearing sunscreen.)

Along with vitamin D, testosterone can also be raised through supplementation or TRT in the case of more severe deficiencies.
