Vitamin D is one of the most studied and researched micro-nutrients over the past decades. There are a few forms of this vitamin and two of them are very important for humans: vitamin D2 (made from plants) and vitamin D3 (made by human skin exposed to sunlight).
This vitamin is responsible for maintaining bone health, decreasing bone fractures, osteoporosis prevention, protection against high blood pressure, cancer and other diseases.
Vitamin D3 Deficiency
A large percentage of individuals are deficient in this very important micro-nutrient. In addition, as we get older we become less equipped to produce adequate amounts of Vitamin D3.
When you take into consideration all the medical research and studies, it becomes clear that Vitamin D affects human health in so many different ways.
Not obtaining adequate amounts of Vitamin D3 can leave us exposed to a number of health conditions.
Vitamin D3 is the only micro-nutrient our body can produce from sunlight exposure, and because of this supplements are especially important for people who do not get enough sun exposure. For example, older people who are not spending a lot of time outdoor or people living in northern latitudes.
Daily recommendations for healthy people from 1 to 70 years of age are 600 IU, and for people over 71 are 800 IU. These RDA recommendations are meant to prevent symptoms related to deficiency.
Higher-risk populations will benefit from doses between 2000 and 4000 IU, which is also the tolerable upper intake level.
Vitamin D3 Benefits
If you’re wondering what is vitamin D3 good for, we’ll give you a breakdown of it’s most important benefits.
This amazing nutrient has a very important role in our overall health and its benefits are both preventative and reparative. Individuals with adequate amounts of vitamin D3 are more likely to have better immune system and avoid a number of health problems.
People that already have certain conditions can also gain welfare from taking this nutrient as it will help them on their way towards disease-free life.
Some of the benefits it provides:
- Reduces blood pressure
- Promotes strong bones and provides bone health

Are there any side effects?
Generally there are no vitamin D side effects, unless it is consumed above it’s recommended dosage.
It is likely to be safe if taken in doses up to 4000 IU daily and applied to the skin alone or in combination with corticosteroids for up to three months.
If you have a particular concern about using a supplement, consult with your family doctor to determine the best steps to take.
There are some cases when it should be used cautiously, for example:
- Pregnant women at risk of high blood pressure associated with pregnancy
- Breastfeeding women
- People with immune disorders, hearth and other diseases
There are many Vitamin D supplements available on the market and most of them will do the job just fine. When choosing a supplement one of the most important things is to select the one with the proper dosage. You may also want to adjust the dosage (take less pills per day) if you spend enough time in the sun.
