author avatar Dr. Eric Berg 04/17/2024

While most people know that getting enough vitamin D and calcium is important, many do not understand the full ramifications of having deficiencies in those areas.

Learn about what vitamin D and calcium do in your body, the common symptoms of a deficiency, and what you can do to increase your intake of these vital nutrients.

Understanding Vitamin D3 and Calcium Deficiency Symptoms

Vitamin D3 and calcium deficiencies can lead to a host of health problems. Inadequate levels of vitamin D3 may be linked to chronic backaches, bone soreness, and muscular frailty.

Symptoms of Vitamin D3 Deficiency

If you constantly feel tired or experience mood swings, it could be due to insufficient vitamin D3.

Frequent sickness or infection is another red flag since vitamin D strengthens our immune system.

Symptoms of Calcium Deficiency

Likewise, with calcium deficiency - its symptoms aren't always evident at first but gradually become more severe over time. Initial signs might include numbness around the mouth or fingertips.

  • Around one billion people worldwide have a deficiency in either vitamin D or Calcium, which is almost one-seventh of the world's population.

  • Osteoporosis is responsible for approximately three-quarters of a million fractures annually. This condition could be due to long-term calcium shortages.

The Role of Vitamin D in Calcium Absorption

Many people are unaware that vitamin D3 is essential for efficient and easy calcium absorption.

The Impact of Vitamin D on Calcium Absorption

Vitamin D acts as a gatekeeper for calcium. It increases the absorption rate by 20 times, mainly in our small intestine.

Without vitamin D's guidance, calcium struggles to reach its destination efficiently.

This means we need enough vitamin D for its benefits and because it helps us use calcium.

Natural Sources of Vitamin D and Calcium

Acquiring adequate amounts of vitamin D and calcium is essential for optimal well-being. Don't just depend on supplements for your vitamin D and calcium needs.

Cod Liver Oil as a Source of Vitamin D

Cod liver oil is an excellent choice for a potent source of vitamin D due to its high nutrient content and additional omega-3 fatty acids.

Not only does it offer an impressive amount of this essential nutrient, but it also provides vital omega-3 fatty acids that promote overall wellness. Cod liver oil benefits are far-reaching, so adding this supplement could benefit your diet.

Dietary Sources of Calcium

Milk often comes to mind first when we think about getting more calcium. However, there are plenty of other food sources out there. Leafy green vegetables like kale or spinach pack a severe punch for this mineral.

Also, nuts and seeds contain reasonable amounts, such as almonds or chia seeds. The key is variety; including diverse foods in your meals can help ensure you receive all necessary nutrients.

Conditions Resulting from Vitamin D3 and Calcium Deficiencies

Health issues may manifest when insufficient amounts of vitamin D3 and calcium are consumed.

Rickets - A Result of Vitamin D or Calcium Deficiency

A common condition resulting from these deficiencies is rickets. It's a disorder that leads to soft bones in children due to insufficient mineralization.

This occurs when the body doesn't have enough vitamin D or calcium. The bone tissue does not stiffen as it should, leading to skeletal deformities such as bowed legs and thickened wrists and ankles.

Besides affecting bone structure, rickets can lead to dental problems and increased infection susceptibility. Thankfully, rickets are preventable with adequate vitamin D intake through diet, supplements, or sensible sun exposure, paired with sufficient dietary calcium.

Factors Affecting Calcium and Vitamin D Absorption

Several factors can influence the human body's ability to absorb calcium and vitamin D. This section will examine these influences in depth, helping you understand how your lifestyle might impact the levels of these essential nutrients in your system.

The Role of Stomach pH in Calcium Absorption

The acidity level significantly impacts your stomach's calcium absorption or pH. The higher the stomach acid level, the better our bodies absorb calcium. So it's crucial to keep that gut health balanced.

Kidney Problems and Calcium Absorption

If you have kidney issues, then this could be affecting your body’s ability to absorb calcium effectively. Kidneys play a crucial role in regulating overall calcium balance within our bodies.

The Impact of Diet and Lifestyle on Vitamin D Levels

Your diet has a direct influence on vitamin D levels. Limited sun exposure, low-fat diets, or certain medical conditions, such as gallbladder or liver problems, can lead to lower-than-optimal vitamin D status.

Stressful situations also tend to decrease nutrient absorption rates, including vitamin D.

How Diet and Other Factors Affect Calcium Levels

Apart from diet, other factors like EMF exposure (think excessive use of electronic devices) may affect how well we manage our calcium levels. In today's tech-filled world, it is essential to consider the potential effects of EMF exposure on calcium balance.

Vitamin D Intake and Dosages

When considering vitamin D intake and dosages, it's essential to recognize the potential benefits of higher doses like 5000 IU. Vitamin D is crucial for various bodily functions, including bone health, immune system support, and mood regulation.

Many individuals opt for vitamin D3 supplements at the 5000 IU level to maintain optimal levels, especially when sunlight is limited. These higher dosages can be particularly beneficial for people with vitamin D deficiencies or those seeking to address specific health concerns.

It's essential, however, to consult with a healthcare professional to determine the correct dosage for your individual needs and to understand the benefits of vitamin D3 in promoting overall well-being.


Maintaining sufficient levels of vitamin D3 and calcium is essential for overall health. Deficiencies in these nutrients can lead to various health problems, including bone issues like osteoporosis and conditions like rickets.

Recognizing symptoms early is crucial for intervention. Vitamin D3 aids in calcium absorption, emphasizing their interconnectedness in supporting bone health.

Natural sources such as cod liver oil and calcium-rich foods like leafy greens are essential.

Lifestyle factors and consultation with healthcare professionals play a role in ensuring adequate intake. By prioritizing these nutrients, individuals can safeguard their health and well-being.
