9. High Blood Pressure and Heart Problems
Vitamin D3 helps regulate blood pressure and cardiovascular health. A deficiency may lead to:
- Elevated blood pressure (hypertension)
- Higher risk of heart disease and stroke
- Increased inflammation in blood vessels
Since hypertension and heart disease are influenced by multiple factors, Vitamin D3 deficiency is rarely considered as a contributing cause.
10. Digestive Issues and Poor Nutrient Absorption
Vitamin D3 is fat-soluble, meaning it needs healthy digestion and fat absorption to be properly utilized. People with digestive disorders are at higher risk of deficiency and may experience:
- Bloating, gas, or stomach pain
- Diarrhea or constipation
- Malabsorption of other nutrients, leading to further deficiencies
Those with Crohn’s disease, celiac disease, IBS, or gallbladder issues should be especially mindful of their Vitamin D3 levels.
