Vitamin D Deficiency Symptoms: Is Your Body Trying to Tell You Something?
Vitamin D is often called the “sunshine vitamin”, but many people don’t realize just how essential it is for energy, immunity, bone strength, and even mood. Low vitamin D levels can creep up quietly—until your body starts sending signals.
Sneaky Symptoms of Low Vitamin D
If you’re experiencing any of the following, it may be a sign your vitamin D levels are too low:
Slow wound healing
Bone pain or achiness in the lower back (without injury)
Chronic fatigue or low energy
Seasonal depression or low mood
Hair thinning or hair loss
Getting sick often or recovering slowly
Muscle weakness or frequent cramps
High blood pressure
Unexplained weight gain
How Do We Get Vitamin D?
About 90% of vitamin D comes from UVB sunlight exposure and the remaining 10% from food sources like fatty fish, eggs, liver and mushrooms. In the darker winter months, it’s easy to fall short.
Why Vitamin D Is Essential
Vitamin D supports:
Bone health – strengthens bones and teeth by improving calcium absorption
Heart health – helps regulate blood pressure and cardiovascular function
Immune function – reduces the risk of frequent infections
Calcium balance – keeps calcium moving to the right places in the body
Vitamin D3 + K2: The Power Duo
When supplementing, look for Vitamin D3 with K2. Here’s why:
Vitamin D3 is more effective than D2 for treating deficiencies and boosting blood levels.
Vitamin K2 works with D3 to send calcium to your bones and heart instead of soft tissues like arteries.
Types of Vitamin D
Vitamin D2 (Ergocalciferol): Plant-based, less effective for raising vitamin D levels
Vitamin D3 (Cholecalciferol): Found in sunlight and animal-based sources, most effective for correcting deficiencies
Risks of Vitamin D Deficiency
Low vitamin D has been linked to:
Osteoporosis and bone fractures
High blood pressure
Type 1 diabetes
Multiple sclerosis
Preterm birth and pre-eclampsia
Rheumatoid arthritis
Certain cancers
Frequent respiratory infections
The Bottom Line
If you’ve been feeling tired, achy, or just “off,” your body may be signaling a vitamin D deficiency. Especially in the fall and winter months, consider adding a D3 + K2 supplement to keep your bones strong, immune system resilient, and mood balanced.
How can we help you do this?
With our monthly vitamin D3 injection of 50,000 IU. This is the standard monthly dose to help you avoid daily vitamins which are easy to forget. If you are deficient, you may need a loading dose of more than one shot per month until levels improve.
Other recommendations:
Get as much sunshine as possible during the winter.
Eat foods rich in vitamin D like sardines, fatty fish, eggs, liver, mushrooms, organic dairy products.
Take a D3 supplement with K2. D3 helps transform the vitamin into calcium for a healthy lifestyle and the K2 tells the calcium where to go. It’s best to take this with a fatty meal.
