The Nutrient Deficiency That’s KILLING Your Gym Performance

Right now, there’s a nutrient deficiency plaguing the world. 

As well as robbing people of strength and muscle…

It may also be a cause of fat gain…

And can lead to a whole host of health issues, including arthritis, diabetes, autoimmune disease, cardiovascular disease, and cancer.

Vitamin D deficiency is thought to affect 1 billion people worldwide...

And there’s a chance it’s affecting you too.

As well as seeing your health skyrocket, correcting this deficiency may also help you to:

  • Build more muscle
  • Lose more body fat
  • Increase your bone density 
  • Strengthen your immune system 
  • Lower your risk of colds and flu

Just imagine seeing rapid changes in your training performance and recovery…

Whilst seeing your physique change shape…

Also from just one single nutrient. 

Pretty cool, right?

It’s Like No Other Vitamin… 

Unlike other vitamins that can only be consumed in foods, Vitamin D can be synthesized by the body via sunlight. 

The UVB radiation from sunlight enters the body via the skin and converts something called ‘7-dehydrocholesterol’ into prev-vitamin D, which is then quickly converted into vitamin D3.

The vitamin D3 is then metabolized in the liver into ’25-hydroxyvitamin D’ (25(OH)D3), which is then metabolized in the kidneys into the active form ‘1,25-dihydroxyvitamin D’. The active form of vitamin D is actually a hormone, known as ‘calcitriol’.

Do You Get Enough Sunlight?

A review from 2007, titled ‘Vitamin D deficiency’ stated that 1 billion people worldwide were estimated to be deficient or at least, insufficient.

2 of the possible causes for widespread deficiencies in this important nutrient are: - 

  1. The lack of sunlight in the winter months
  2. The overuse of suncream in the summer months (an SPF 15 or higher will block 99% of all UVB radiation)

UVB radiation is very limited at latitudes above 35° (every state above the northern Tennessee border), and completely non-existent between November-February. 

A high prevalence of vitamin D deficiency has been found in the USA, with up to 35% of adults in the USA being deficient in this essential nutrient. 

Sources Of Vitamin D

Although Vitamin D can be obtained from the diet from foods such as wild-caught fatty fish and eggs, the quantities are negligible in comparison to what can be created from sun exposure.

Whilst you may be able to maintain optimal vitamin D levels via diet alone, if you are currently suffering from a deficiency, then the quantities in food may be too low to help restore you to optimal levels.

Therefore, outside of the summer months, the most simple way to ensure you’re getting enough of this life-enhancing nutrient is to take it as a supplement. 

Take The Right Supplement

When supplementing with Vitamin D, be sure to choose vitamin D3 over vitamin D2. 

Whilst they’re both dietary forms of vitamin D, vitamin D3 has been shown to be far more superior at raising vitamin D levels in the body. 


Every cell in the human body has a receptor for vitamin D, which means there isn’t a single cell that vitamin D doesn’t influence. 

The benefits of supplementing a vitamin D deficiency are vast, and may include - 

  • Improved insulin sensitivity 
  • Improved appetite control 
  • Increased strength and muscle 
  • Decrease the risk of cardiovascular disease
  • Decrease the risk of flu
  • Decreased bone fracture risk
  • Decreased risk of some cancers
  • Supports the maintenance of healthy bones and teeth
  • Supports a healthy immune system
  • Supports cardiovascular function and calcium absorption

NSP Vitamin D3-5000

NSP has created an ultra-potent vitamin D3 supplement, containing a massive 5,000iu of D3, manufactured into a liquid softgel form that is easily absorbed by the body. 

How To Take

Take 1 x softgel a day.

Dietary sources of vitamin D (including supplements) are incorporated into ‘chylomicrons’ (a combination of triglycerides, phospholipids, cholesterol, and proteins) before entering circulation.

For this reason, make sure you take vitamin D supplements with a source of dietary fat to aid with absorption.
