About the Ultimate Vitamins Blood Test

Check and manage the level of vitamins B12 (both active and total), vitamin B9 (folate) and Vitamin D, in your body, with this test.

Vitamin B12

Vitamin B12 is essential for most body systems, particularly in haematology with the manufacture of blood cells and hence healthy function of the organism as a whole, including the nervous system. Symptoms of low vitamin B12 are abundant, including tiredness, lack of energy, headaches and many others.

This test measures both active and total levels of Vitamin B12

Total B12 refers to the measurement of all forms of vitamin B12 present in the blood. This includes both active B12 (methylcobalamin and adenosylcobalamin) and inactive B12 forms (such as cyanocobalamin). The measurement of total B12 provides an overall picture of the total B12 content in the bloodstream, regardless of whether the B12 forms are actively available for body use.

Active B12, also known as cobalamin, refers to the biologically active forms of vitamin B12 that are immediately available for the body to use. The two primary active forms are methylcobalamin and adenosylcobalamin. These active forms play essential roles in various physiological processes, particularly in energy metabolism and nerve function.

Why it is important to measure both.

The distinction between total B12 and active B12 is crucial because not all forms of B12 are biologically active or readily usable by the body. Cyanocobalamin, for example, is an inactive form of B12 that requires conversion into active forms before the body can utilise it. Methylcobalamin and adenosylcobalamin are already in their active forms and can be directly utilized by cells.

In some cases, only total B12 levels are measured, which may not give a complete assessment of B12 status. It is often beneficial to measure active B12 levels (or other markers like free B12/holotranscobalamin) to better understand the body`s immediate access to functional B12.

This test measures both forms.

Vitamin D

Vitamin D is a fat-soluble vitamin that plays a crucial role in various physiological processes in the human body. Vitamin D is produced in the skin when it is exposed to sunlight and manifests itself in the more biologically active form of D3.

Vitamin D is important for the following:

Bone Health: Vitamin D is essential for the absorption of calcium and phosphate from the gastrointestinal tract. These minerals are critical for maintaining strong and healthy bones. Without enough vitamin D, the body cannot absorb enough calcium, leading to weakened bones and conditions like rickets in children and osteoporosis in adults.

Immune System Support: Vitamin D plays a role in supporting the immune system. It helps the body fight off infections and illnesses, and deficiencies in vitamin D have been associated with an increased risk of infections.

Cell Growth and Function: Vitamin D is involved in regulating cell growth and differentiation. It may have a role in preventing the development of certain cancers, though more research is needed in this area.

Mood and Mental Health: Some studies suggest that vitamin D may have a role in mood regulation, and deficiencies have been linked to conditions like depression and seasonal affective disorder (SAD).

Heart Health: Adequate vitamin D levels are associated with a lower risk of heart disease. It may help regulate blood pressure and reduce inflammation.

Muscle Function: Vitamin D is important for muscle strength and function, and deficiency can lead to muscle weakness and pain.

Autoimmune Diseases: Some autoimmune diseases, such as multiple sclerosis, rheumatoid arthritis, and type 1 diabetes, have been linked to low vitamin D levels.

Regulation of Calcium: Vitamin D helps maintain proper levels of calcium in the blood, which is crucial for muscle function, nerve transmission, and blood clotting.

Longevity: Some research suggests that maintaining adequate vitamin D levels may be associated with a longer lifespan and reduced risk of chronic diseases.

Vitamin D can be obtained through dietary sources such as fatty fish (e.g., salmon and mackerel), fortified foods (e.g., fortified milk and cereals), and supplements. However, the body can also produce vitamin D when the skin is exposed to sunlight. Therefore, a balance between sun exposure, diet, and supplements can help ensure sufficient vitamin D levels in the body.

It is important to note that excessive vitamin D intake can lead to toxicity, so it is advisable to consult with a healthcare professional before taking high-dose supplements. Additionally, individual vitamin D requirements can vary, so it is essential to monitor your levels through blood tests if you have concerns about deficiency or excess.

Vitamin B9 - Folate

Vitamin B9, also known as folate or folic acid, is a water-soluble B vitamin that plays a crucial role in various essential functions within the body. It is an essential nutrient, meaning that it must be obtained from the diet because the human body cannot produce it on its own.

4 Biomarkers


    - Total Vitamin B12
    - Active Vitamin B12
    - Vitamin D
