Vitamin D3

Vitamin D3 is a fat-soluble vitamin that’s considered by sports scientists to be essential for boosting the immune system, enhancing recovery and ultimately helping the entire body cope with the physical stress it’s put under during periods of intense training.

It has also been shown to play an important role in reducing inflammation in body tissue, again a common problem of overtraining and intense exercise. More traditionally Vitamin D3 was recommended for its general health benefits and its ability to improve the maintenance of bones, teeth, and joints.

Vitamin D3

Vitamin D3 has been considered an essential vitamin in sports nutrition for years, which is why it is recognized as a must-have supplement at TPW™ Towers today. Along with its immune boosting properties, Vitamin D3 also contributes to overtraining prevention and recovery. Vitamin D is found in foods such as oily fish, milk and eggs, although to meet your daily requirements, taking a tablet form, such as TPW™ Vitamin D3 2500iu tablets, is much more convenient.


Vitamin D3 Benefits

Now specifically for athletes and those who train, when working at 90% of your maximum heart rate or near exhaustion your immune system can become suppressed. This is because your oxygen usage skyrockets which in turn causes an increase in lactic acid accumulation in the muscles, which in turn causes your body to pull alkaline reserves from bones and other mineral dense sources. It’s what’s known as an ‘immune crash’ and it’s during this time that your body is susceptible to viruses, bacteria and overtraining. Vitamin D3 has been shown to help combat this since it plays a crucial role in activating the body’s 'T' Cells (the cells in the body that seek and destroy anything ‘foreign’ that enters the body such as bad bacteria or a virus). Vitamin D3 is therefore a great supplement for those who want to prevent overtraining.


Vitamin D3 Health Benefits

Vitamin D3 has also been shown to play a role in reducing inflammation in body tissues, again a common problem of overtraining and intense exercise. This is especially important for athletes who undergo heavy, compound movements on a regular basis or anyone who continually loads their body above its habitual level during training or competition.

Furthermore, more recently there’s been promising evidence that suggests Vitamin D3 levels are associated with the maintenance of power and strength by potentially increasing the size and number of fast twitch fibres. This means that Vitamin D3 supplementation could not only improve immune function and prevent overtraining, but actually have performance enhancing properties too.

Whilst Vitamin D3 is often used as a permanent supplement in most athlete’s nutrition plan, it’s particularly important during winter training since it’s during this period when the body can become deficient in it due to lack of sunlight. This is why it’s recommended to take Vitamin D3 in the months leading up to the winter so it can accumulate in the body and therefore boost immune health.

Whilst studies vary on the adequate amount of Vitamin D levels in the body, the most often cited amount is 2000iu per day.

Vitamin D3 is a great product to further enhance the immune system when combined with Green Tea and Green Coffee, It also works well in boosting testosterone levels in males.

It can also help strengthen bones, I find it is essential to supplement this in the winter months when we do not get much sun to keep levels topped up.

Since using these and Green Tea Extract I no longer get colds or Flu from work colleagues and have increased energy levels and strength, this is a great product for anyone requiring more performance at the gym.

great for mood, great for keeping those irritating colds at bay. feel 100% when supplementing with this vitamin! an essential in my daily routine!
Great addition to any supplement stack. Vitamin D has been linked to both immune system support and happiness levels so I make sure to take them even if I am taking a multivitamin.
I've never taken these before,but I started to take them a few weeks ago as an insurance policy against the stresses and strains of heavy ,intense prolonged training and so far so immune system is in tip top shape and I feel really good in myself.I take one of these along with vitamin c,glutamine and supergreens advanced in the morning.
Having a period of sustained heavy training/cutting diet so felt I needed a boost to protect my immune system and these have really helped me! I take one in the morning with Breakfast and even with a punishing routine of gym/day-job/calorie deficit/carb back-loading I still feel fresh every day.
Great value, great happy pills!

My whole family take these now as a little boost.
Definitely feeling a huge difference in energy levels after introducing these to my supplement stack! Would definitely recommend these!
