Benefits, Dosage, & Side Effects
Vitamin D3 is oftentimes overlooked by athletes and gym freaks because the market places more focus on supplements such as L-Carnitine, Creatine and Whey Protein. A deficiency in Vitamin D3, however, can cause a great variety of health problems, including depression, fatigue, muscle pain and more. In men, low levels of Vitamin D3 have interestingly been correlated with decreased testosterone and sex drive. It makes sense when you think about it – most of us feel more energized, active and zestful during the summertime, and that’s because the sun is our main source of Vitamin D3.
But the secret to Vitamin D3 that most people don’t know about is that it’s not actually a vitamin to begin with. Based on its function and the benefits that it provides the human body with, Vitamin D3 is technically considered a steroid hormone. Sounds scary at first, but Vitamin D3 does not lead to the same dangerous side effects that corticosteroid injections cause, because it’s a nutrient that the body naturally needs to function properly.
Paying closer attention to the benefits of Vitamin D3, its mechanisms of action and its proper dosages can not only help you understand why the supplement is so important, but also prevent the deterioration of certain bodily functions.
When you want to achieve superior performance and enhance your body’s natural abilities to its optimal levels, a supplement like Vitamin D3 doesn’t usually come to mind. We know that Vitamin D3 is something our bodies need to function properly, so we assume that the nutrient would be useless when trying to go beyond the norm. That assumption shows a misunderstanding. It is in fact a depletion of essential nutrients that cause our bodily functions to perform below ideal expectations. For instance – if you’re a middle-aged guy who is having problems in the bedroom and suffering from erectile dysfunction, your issue could be low testosterone levels. In order to fix this and prevent it from happening again without getting damaging side effects, you need a supplement that compliments your body’s natural pathways rather than one that goes against it. A corticosteroid injection, for instance, is not something your body is short of. Vitamin D3, on the other hand, potentially could be.
By supplementing with Vitamin D3, you can experience improved overall mood. Vitamin D3 is associated with neurotransmitter production in the brain, mostly serotonin and GABA, both of which help to reduce anxiety and promote better sleep quality.
Vitamin D3 has also been shown to increase testosterone levels in men, which in turn enhances sex drive, libido, energy, and muscle strength. Plenty of men choose Vitamin D3 as their go-to testosterone booster as it is a natural supplement that works effectively with very minimal potential side effects.
Vitamin D3 also plays a role in regulating your immune system. According to MedicalNewsToday.com, supplementing with Vitamin D3 may even fight against the development of various illnesses such as diabetes, multiple sclerosis and cancer .
How It Works
For each benefit that Vitamin D3 can potentially bring, its mechanisms of action have fortunately undergone clinical trials.
Vitamin D3 helps prevent diabetes, for instance, by regulating insulin levels in the bloodstream. Meanwhile, Vitamin D3 has been shown to ward off cancer by interacting with certain gene expressions in our DNA. A study published in the American Journal of Public Health in 2006 presented a theoretical explanation of Vitamin D3’s role in preventing cancer development . The contents of the study discuss how a deficiency in Vitamin D3 has been strongly linked to different types of cancer. It was therefore concluded that moderate supplementation of Vitamin D3 may be an effective way of maintaining overall wellbeing and suppressing cancer cell growth.
In relation to testosterone levels in men, Vitamin D3’s effects have been researched fairly extensively. One study examined the effects of Vitamin D3 administration on the testosterone levels of 54 men over the course of 1 year . Half of the participants received 3,332 IU of Vitamin D3 while the other half did not. Results showed that those who did receive Vitamin D3 supplementation had 25.2% more testosterone than those who did not. In another study published in the Clinical Endocrinology Wiley Online Library, men with normal levels of Vitamin D3 in their bloodstream had increased levels of total testosterone . But how does Vitamin D3 help with the production of testosterone? One theory suggests that Vitamin D3 triggers the release of LH (luteinizing hormone), which communicates with the Leydig cells in the testes to create more testosterone.
The point is – multiple research studies consistently show time and time again that there is a significant correlation between sufficient levels of Vitamin D3 and healthy testosterone levels.
If you have low testosterone levels then your Vitamin D3 intake should be higher, in attempt to restore optimal T-levels. Dr. Michael Aziz from LifeExtension.com recommends 4,000 – 5,000 IU of Vitamin D3 daily to naturally boost testosterone levels. However, if you simply would like to maintain good levels of Vitamin D3 then a high quality supplement of 400 – 1,000 IU should be sufficient.
Potential Side Effects
Vitamin D3 in most cases does not cause adverse side effects. However, you may experience bad reactions if you are allergic to Vitamin D3 – can be shown through the appearance of rashes and itching. In rare occasions, Vitamin D3 may potentially cause dizziness and difficulty breathing.
Where to Get It
Vitamin D3 is an over-the-counter supplement so you can pretty much buy it from your local pharmacy or online. You can purchase it as an individual supplement, in a multi-vitamin or from a high-quality test-booster.
