Who should take the test?

The B Vitamins test is strongly recommended for individuals who may encounter a spectrum of symptoms linked to B Vitamin deficiency. These symptoms encompass hair loss, muscle weakness, fatigue, memory issues, headaches, depression, numbness and tingling in the hands and feet, anemia, and a diminished sense of taste.

Considering that as many as 6% of individuals under the age of 60 and up to 20% of those over 60 in the United States may not meet the recommended vitamin B9 and B12 intake, our test offers a valuable opportunity for those concerned about deficiency or interested in monitoring their B9 (Folate) and B12 levels to gain insights into their health and well-being.

Test measures
For the B Vitamins Test we analyze:
  • Vitamin B12
  • Vitamin B9 (Folate)
Vitamin B12

Vitamin B12, scientifically known as Cobalamin, is a water-soluble essential nutrient, meaning our bodies cannot produce it on their own, necessitating a sufficient dietary intake.

This crucial vitamin plays a pivotal role in breaking down individual fatty acids, facilitating blood formation, supporting nerve function, and promoting cell division. Consequently, a deficiency in Vitamin B12 can have far-reaching effects, affecting various bodily systems, including the eyes, nerves, muscles, and even hair.

Symptoms of this deficiency encompass hair loss, muscle weakness, fatigue, memory impairment, headaches, depression, tingling sensations in the limbs, anemia, and allergies.

The daily recommended intake of Vitamin B12 for adults is approximately 4µg, primarily sourced from animal products like meat, fish, dairy, and eggs. Consequently, individuals adhering to vegan or vegetarian diets may be at higher risk of Vitamin B12 deficiency if they do not supplement their intake.

Additional risk factors include autoimmune disorders, pregnancy, impaired gut absorption (e.g., in conditions like celiac disease or Crohn’s disease), and certain medications, such as those for diabetes and acid indigestion.

Importantly, the risk of overdosing on Vitamin B12 is exceedingly low, as the body efficiently eliminates any excess through the kidneys.

Vitamin B9 (Folate)

Vitamin B9, also known as folate, plays a crucial role in various metabolic processes such as protein and DNA synthesis, making it essential for cell division.

Rich sources of folate include spinach, lettuce, asparagus, cereals (especially wheat germ), and liver, as other foods generally contain low levels of folate. It’s important to note that folate is sensitive to heat and can be diminished through cooking and frying.

Folate deficiency is not uncommon, with pregnant women, breastfeeding women, and smokers being more susceptible. A lack of folate can result in a shortage of red and white blood cells, leading to anemia. In pregnant women, folate deficiency increases the risk of neural tube defects in the developing fetus, potentially causing congenital defects and malformations.

Additional symptoms of folate deficiency may include muscle weakness, reduced sense of taste, depression, numbness and tingling in the extremities, diarrhea, but overdosing on vitamin B9 is highly unlikely to pose health risks.

Symptoms the B Vitamins Test is suitable for:
  • Tiredness
  • Lack of concentration
  • Allergies
  • Poor memory
  • Depressive moods
  • Muscle weakness
  • Anemia
  • Hair loss
  • Headaches
  • Reduced sense of taste

Any Questions?

Here are some of the most frequently asked questions regarding this test. Your question is missing? Please contact us at:

I am not getting enough blood from my finger, what can I do?

In order to draw more blood from your finger, begin by warming your hand under running warm water for a few moments and gently rotate your arm to enhance blood circulation. When it's time to prick your finger, aim for the side of the finger rather than the tip. It's often easier to use the middle or ring finger of your non-dominant hand. To prevent any involuntary withdrawal during the piercing, place your finger firmly on a stable surface. Finally, apply a gentle squeeze and massage towards the fingertip to encourage blood flow.

What exactly is Vitamin B12 deficiency?

Vitamin B12 deficiency is a condition where the body lacks an adequate amount of vitamin B12, a vital water-soluble nutrient. It can result from factors like inadequate dietary intake, poor absorption due to medical conditions or medications, and can lead to symptoms such as fatigue, anemia, cognitive problems, nerve damage, mood changes, and more. Severe or prolonged deficiency can lead to serious health issues and should be managed under medical guidance.

How can I tell if I have a deficiency of Vitamin B9 (Folate)?

A Vitamin B9 (Folate) deficiency may show signs such as anemia, neurological symptoms like numbness, digestive issues, mood changes, reduced immunity, altered taste perception, mouth sores, pregnancy complications, fatigue, and muscle weakness.

Are excess amounts of Vitamin B9 and B12 dangerous?

Excessive intake of Vitamin B9 (Folate) and B12 (Cobalamin) is generally considered safe because these water-soluble vitamins are excreted by the body when not needed. However, it's essential to follow recommended intake levels and avoid high-dose supplements without a specific medical reason, as excessive supplementation can have potential side effects or mask other deficiencies, particularly with synthetic folic acid in the case of B9.

Can I supplement my Vitamin B9 and B12 levels through food?

Yes, you can boost your Vitamin B9 (Folate) and B12 (Cobalamin) levels through dietary sources. Foods like dark leafy greens, legumes, citrus fruits, animal products, and fortified options are rich in these vitamins. However, in some cases, dietary restrictions or specific health needs may require supplementation.
