As we know, one of the best nutrients for boosting natural testosterone is Vitamin D3.
Vitamin D3 is one of the most underrated vitamins in the health industry and is technically classed as a hormone.
If you’re looking to naturally boost your testosterone this is an essential nutrient you want in your stack.
This article will teach you the benefits of Vitamin D3, the best source of it and why you should be supplementing it.
How do we get Vitamin D3?
Although a vital nutrient, Vitamin D3 can be one of the hardest nutrients to get enough of on a daily basis.
It has been reported that over 1 Billion people may be Vitamin D deficient. 
That’s because most of the vitamin D you get throughout the day is synthesized through your skin from the sun’s rays and affects around 2000 genes in your body.
Getting enough Vitamin D from the sun is allows us to enjoy the following benefits:
- Higher Testosterone Levels
- More Energy in the Day
- Prevents illness and promotes immunity
- Stronger bones and joints
However not everyone gets enough Vitamin D3 – and the problem is modern living.
That’s right, your country and lifestyle may be a key factor in deducing if you are getting enough Vitamin D throughout the day – and if you’re testosterone levels are well supported.
If you feel tired and sluggish on a daily basis, your lack of Vitamin D may be the problem.
Usually most people who work in offices or live in more overcast countries like the UK experience the worst of this as they are not exposed to enough sunlight throughout the day for their body to benefit.
And that makes a big difference.
But can’t I get Vitamin D3 in my diet?
Technically you can get Vitamin D in your diet, but there’s a drawback.
The places that you can find Vitamin D are usually in diary products and milks.
This is Vitamin D2 – a synthetic and weaker alternative.
This is a form of Vitamin D that our body struggles to absorb, and even if it does the effects aren’t that beneficial, with numerous studies vouching that:
- D2 is more toxic than D3
- D2 is less stable than D3
- Studies have shown that D2 is harder to absorb
- D3 has a lot more clinical evidence behind it
There are numerous studies that vouch for D’s effectivness over D2 
The Studies Behind Vitamin D3
If you’re concerned that you’re not getting enough Vitamin D, supplementing it is the answer.
Various studies have been published throughout the years vouching for Vitamin D3’s effectiveness.
One of the best studies that reflects the effectiveness of Vitamin D3 supplementation involved a group of men taking 3,332 IU of D3 for a year. The changes in their T-levels were dramatic with high raises in blood and serum testosterone being reported. 
There’s also some good evidence for it helping with the immune system. A study that involved supplementing Vitamin D3 in school children showed a 58% reduction in breakouts of influenza among the participants. 
Aside from it’s abilities to help raise testosterone and strengthen the immune system, Vitamin D3 is also good for the bones and can help towards stronger bones and teeth as you get older.
How should I be getting Vitamin D3?
If you’re part of the 1 billion that aren’t getting enough Vitamin D3 each day, supplementing it is definitely the right way to go.
Natural Testosterone Boosters are a good choice and contain a wide range of nutrients targeted to raising T-levels and promoting overall health. The top ones on the market use plenty of Vitamin D3 along with other core ingredients such as zinc and magnesium to make sure you have everything you need.
