Unique in that it can be synthesized by the body through skin exposure to sunlight, specifically ultraviolet B (UVB) radiation, Vitamin D is also found in certain foods. However, factors such as living in areas with limited sunlight, spending more time indoors, or using sunscreen can contribute to insufficient Vitamin D levels. Dietary sources like fatty fish, cheese, egg yolks, and fortified foods (e.g., milk and cereals) can help, but it may be difficult to meet daily requirements through diet alone.

As a biomarker, Vitamin D is often assessed through a simple blood test, typically measuring the level of 25-hydroxyvitamin D (25(OH)D) in the blood. This form of Vitamin D is the best indicator of your overall Vitamin D status.

Vitamin D deficiency is defined as a 25(OH)D level below 20 ng/ml (50 nmol/l), while insufficiency ranges from 20–29 ng/ml (50–74 nmol/l). Normal levels are considered to be above 30 ng/ml (75 nmol/l), though the optimal level may vary slightly depending on expert opinion.

Vitamin D Deficiency Can Lead to:

Bone Health Issues: Rickets in children (soft bones and skeletal deformities) and osteomalacia in adults (weak bones and muscle weakness).
Weakened Immune Function: Increased vulnerability to infections.
Chronic Diseases: Low Vitamin D levels may be linked to an increased risk of certain cancers, autoimmune diseases, neurological disorders, insulin resistance, and cardiovascular disease.
Home health tests for Vitamin D levels are especially important for individuals at higher risk, such as older adults, those with limited sun exposure, individuals with darker skin, and those with conditions that hinder the body’s ability to absorb or convert Vitamin D. It’s essential to consult a healthcare provider about your results, who can offer tailored advice and recommend treatment options if your Vitamin D levels are low.

Our Welzo HDL test measures your HDL levels and provides valuable insights on how to improve them, empowering you to take proactive steps toward better cardiovascular health.

Elevated CRP levels are also commonly found in individuals with chronic inflammatory conditions like rheumatoid arthritis, as well as those who have recently experienced a heart attack or stroke. Monitoring CRP can provide important insights into your risk for cardiovascular issues and inflammation-related health concerns.

Cortisol is essential in the following areas of human health:

Stress Response: When you encounter stress, such as physical injury or emotional pressure, your brain signals the adrenal glands to release hormones, including cortisol and adrenaline. This surge prepares your body for a “fight or flight” response—adrenaline increases heart rate and blood pressure, while cortisol helps prioritize energy and restricts non-essential functions.

Metabolism Regulation: Cortisol helps regulate blood sugar levels and the metabolism of carbohydrates, proteins, and fats. It ensures your body has a constant supply of energy by supporting the breakdown of these nutrients.

Inflammation Reduction: With its anti-inflammatory properties, cortisol plays a key role in reducing inflammation, making it vital for managing conditions like asthma and rheumatoid arthritis.

Blood Pressure and Cardiovascular Health: Cortisol helps maintain stable blood pressure and supports cardiovascular function, contributing to overall heart health.

Sleep/Wake Cycle: Cortisol follows a daily rhythm, peaking in the morning to help you wake up and gradually decreasing throughout the day, helping regulate your circadian rhythm.

While cortisol is necessary for these functions, maintaining a balance is crucial. Chronic high cortisol levels can lead to conditions like Cushing’s syndrome, while low levels can result in Addison’s disease.

As a biomarker, cortisol levels are often assessed to evaluate the body’s response to both acute and chronic stress, and to diagnose adrenal gland disorders. Cortisol can be measured using blood, saliva, or urine tests, providing valuable insight into your stress levels and overall health.

Monitoring triglyceride levels is crucial when assessing overall cholesterol health, as high triglycerides often accompany high LDL (“bad”) cholesterol and low HDL (“good”) cholesterol, contributing to a higher risk of heart-related conditions.
