Vitamin D Deficiency is a Worldwide Epidemic

Updated: Sep 5, 2022

In the past 50 years our world has changed drastically. And with all of these changes, vitamin D deficiency is now a global public-health problem affecting an estimated 1 billion people worldwide. Why though? Well, we are no longer outdoors like we were in years past. We work inside, play inside, and have allowed air conditioning and technology to keep us inside. The result on society is a vast increase of obesity, a plethora of health problems, and even a major crisis of vitamin D deficiency.

What the big deal? Aren’t we all deficient in some vitamins? Well, sure; however, there is something very unique about vitamin D. It becomes a secosteroid hormone in our bodies. It is an extremely important vitamin that affects many parts of our body, including; our skeletal structure, but also our blood pressure, immunity, mood, brain function, and ability to protect ourselves from cancer!

The best source of vitamin D is direct sunlight, without sunscreen or skin protectors. Our bodies can absorb up to about 10,000 units of natural vitamin D in just 15 minutes of sunlight a day. Unfortunately, with our busy indoor lives, we do not always have even that amount of time to get the vitamin D our bodies so desperately need. Even if we do get the exposure to sun, if we shower or bath less than 48 hours afterwards, we prevent the vitamin D absorption from our skin.

There are some great food sources we can eat regularly to help get the vitamin D we need as well. A few to add to your diet are; salmon, sardines, egg yolk, wild caught shrimp, eel, halibut, carp fish, mackerel, portobello and maitake mushrooms, tuna and raw milk.

Supplementation of vitamin D3 is vital because it gives us the assurance that we are getting enough of the vitamin D our bodies need to fight diseases and help us remain healthy!

Let’s take a deeper look into why vitamin D is vital:

First, let look at the risk factors.

  • Living near highly polluted areas

  • Using sunscreen

  • Spending most of your time indoors

  • Living in big cities with tall buildings

  • Having darker skin

  • Bathing regularly

What are the signs of vitamin D deficiency?

  • getting sick often

  • fatigue

  • depression

  • severe bone or muscle pain

  • weakness

  • wounds that do not heal quickly

  • stress fractures, especially in your legs, pelvis, and hips

  • bone loss

  • hair loss

  • cognitive impairment in older adults

What are the Benefits of Vitamin D?

Vitamin D fights disease, including cancer! One study in, The Journal Anticancer Research showed that breast cancer patients with healthy levels of vitamin D are twice as likely to survive the disease as patients with lower levels!

There have been numerous studies showing the many positive affects of vitamin D in our bodies:

  • Reduced risk of cancer (1)

  • Stronger bones

  • Reduces depression

  • Decreases your chance of developing heart disease (2)

  • Reduces chances of developing flu (3)

  • Boosts weight loss

  • Decreased risk of type two diabetes (4)

  • Improved muscle function

  • Reduces your risk of multiple sclerosis. (5)

  • Cognitive health. (6)

  • Help prevent osteoporosis.

  • Treat rickets.

It is clear that we must make getting enough vitamin D in our bodies a priority. We carry a physician-grade liquid Vitamin D3 in our natural pharmacy and we offer lab work to measure vitamin D3 levels. It is believed to be the closest to what sunlight produces when our skin works to convert UV. It also absorbs at a faster rate than other types of vitamin D.
