4 Reasons Your Body Needs Vitamin D3 & How To Tell If You’re Deficient

 

 

Key findings:

 

  • Vitamin D3 is essential for immunity since it regulates the activity of critical immune cells.
     
  • Vitamin D3 regulates neurotransmitters involved in feelings of well-being and happiness. This may help explain the link between Vitamin D deficiency and depression/seasonal affective disorder.
     
  • Vitamin D3 plays an essential role in joint and bone health by supporting calcium absorption in the intestines and regulating inflammation. Deficiency could lead to achy and painful joints and sore muscles.

  • Vitamin D3 also regulates blood sugar balance by helping to increase the body’s sensitivity to insulin.

  • Taking a Vitamin D supplement is the most effective way to ensure you're getting sufficient Vitamin D, especially when you're not getting regular sun exposure.
  •  

    With over 40% of Americans suffering from low Vitamin D3 levels, it’s safe to say this deficiency is an epidemic! And it’s pretty likely you’re not getting enough. Our bodies need Vitamin D3 to function correctly, and low levels can leave you tired and under the weather, weakening your immunity and bone health. [1] No thanks!

    Vitamin D is called the sunshine vitamin since it’s produced in our bodies when our skin cells are exposed to UV rays from the sun [2]. But with modern lifestyles and seasonal changes, it can be challenging to get enough. Even though it’s found in some foods, it’s almost impossible to get adequate quantities through diet alone, leading to Vitamin D deficiency.

     

     

    What are the symptoms of Vitamin D deficiency?

     

    • Fatigue or tiredness
    • Bone pain or muscle weakness
    • Depression
    • Impaired wound healing
    • Hair loss
    • Increased risk of infections
    • Softening of the bones (osteomalacia)
    • Delayed growth in children
    • Bone fractures in older adults

     

    N.B: The above symptoms may not only be specific to low Vitamin D levels - a doctor's diagnosis is necessary to confirm Vitamin D insufficiency. 

    Keep reading to find out how Vitamin D3 works its magic in your body and the best way to raise your levels fast and effectively to avoid Vitamin D deficiency...

     

     

    1. Immune Health

     

    Your immune system is packed with Vitamin D3 receptors. Vitamin D3 comes in to fill these receptors, regulating the activity of critical immune cells in the process [3].

    Vitamin D3 also increases cathelicidin, a chemical with potent antimicrobial properties that helps to fight off foreign invaders and improve immune function. Studies even show that supplementation with Vitamin D3 may reduce the risk of respiratory tract infections [4] [5].

     

     

    2. Sunny Mood

     

    Feeling blue? Clinical trials have shown that Vitamin D3 deficiency and depression go hand-in-hand. Vitamin D3 affects mood in multiple ways by regulating serotonin and dopamine, two essential neurotransmitters involved in feelings of well-being, happiness, and sleep [6] [7].

    There may also be a link between Vitamin D3 deficiency and seasonal affective disorder (SAD) since Vitamin D3 stores are typically depleted during the winter months as people get less exposure to sunlight. With this link in mind, researchers found that Vitamin D3 supplementation was associated with a significant improvement in depression scores in those with SAD! [8]

    Doctors in the northern hemisphere commonly prescribe a Vitamin D supplement to maintain adequate levels, particularly during winter.

     

     

    3. Joint & Bone Health

     

    One of Vitamin D’s top roles in the body is to support calcium absorption in the intestines. Calcium is an essential mineral required for strong bones and muscle contraction. And because of Vitamin D’s prime role in its absorption, Vitamin D deficiency may also be associated with low calcium levels. Calcium absorption is essential for maintaining bone mineral density [9] [10].

    Not only is Vitamin D3 essential for bone health, but research also shows that deficiency in this vital vitamin may result in achy, painful joints and sore muscles. Clinical studies have found that supplementing with Vitamin D3 may help soothe joint discomfort by supporting healthy inflammatory responses [11] [12].

     

     

    4. Blood Sugar Balance

     

    Blood sugar balance is an essential foundation for overall health. Keeping your blood glucose levels stable can help to support sustained energy and weight loss, protect brain health and even support healthy cardiovascular function! [13] [14] 15] [16] 

    Vitamin D3 plays an essential role in how your body regulates blood glucose, so much so that Vitamin D3 deficiency has even been associated with an increased risk of developing type 2 diabetes! You see, Vitamin D3 helps to increase your body’s sensitivity to the hormone insulin, which transports glucose out of the blood and into your cells to produce energy [17] [18].

     

     

     

    The Best Way To Benefit From Vitamin D3

     

     

    Vitamin D3 supplementation is the most effective and efficient way to get your Vitamin D stores to optimal levels, especially if your access to sun exposure is or you have a history of skin cancer.

    However, not all Vitamin D supplements are created equal, and many fall short... This is why we created AdaptoZen Vitamin D3 + K2 Drops!

    Vitamin D3 is the most bioactive and bioavailable form of Vitamin D, proven to boost Vitamin D levels significantly more than Vitamin D2. That's why we’ve included a potent dose of 5000 IU of D3 in our convenient, fresh peppermint-flavored formula. Since Vitamin D3 is a fat soluble vitamin, we’ve also included organic olive oil and MCT oil for maximum absorption. [19] [20].

    But did you know that taking dietary supplements containing only Vitamin D3 isn’t the best idea? As mentioned, Vitamin D supplementation enhances calcium absorption, which can be problematic since excess calcium can get stored in soft tissues like arteries, which may increase the risk of heart disease. 

    Vitamin K2 helps to direct calcium into your bones where it is needed, preventing calcium deposits in soft tissue. This makes Vitamin D3 and Vitamin K2 the perfect partnership! [21]

    Before you go, if you’d like to increase your Vitamin D intake through dietary sources, you may be wondering what foods are highest in Vitamin D. Let’s take a look:

    • Fatty fish such as salmon, tuna, and mackerel
    • Egg yolks
    • Mushrooms
    • Beef liver

     

     

     


    Final Thoughts

     

    In conclusion, Vitamin D3 is a vital nutrient for our overall health and well-being. It plays a crucial role in immunity, mood regulation, joint and bone health, and blood sugar balance. With over 40% of Americans suffering from low levels of Vitamin D, it's clear that this deficiency has reached epidemic proportions. The best way to ensure you're getting enough of the sunshine vitamin is to add a Vitamin D3 + K2 supplement to your daily regimen, especially when there is limited sun exposure.

    Don't let a deficiency hold you back, boost your levels and feel the magic of Vitamin D3 working its wonders in your body!
