Lab Marker of the Week: Vitamin D
Vitamin D is often referred to as the "sunshine vitamin," but it's actually a hormone that plays a vital role in many of the body's physiological processes.
While it's best known for supporting bone health, adequate Vitamin D is also essential for:
• Immune system function
• Muscle strength and recovery
• Cardiovascular health
• Healthy inflammatory response
• Mood and cognitive function
Low Vitamin D levels are common and may contribute to symptoms such as:
• Fatigue
• Muscle weakness or aches
• Frequent illness
• Low mood
• Slow recovery from exercise or injury
Many factors can influence Vitamin D status, including:
• Limited sun exposure
• Geographic location and season
• Age
• Skin pigmentation
• Diet and nutrient absorption
At Science Based Nutrition, we believe that optimizing Vitamin D status is about more than supporting healthy bones, it's about promoting whole body wellness through personalized, data driven care.
Because when it comes to long-term health, even one nutrient can have a widespread impact
