Frequently asked questions

How is the Vitamin B12 test performed?

Our Vitamin B12 test is a home test. After ordering, we will send you a kit with everything you need to collect your blood sample. Then you simply return your sample to us in the included prepaid return envelope.

Why do you measure active B12 instead of total B12?

Active B12 (Holotranscobalamin) is the form that the body's cells can actually utilize. A standard test can show normal levels even if the active form is too low, as active B12 only accounts for 10-30% of total B12.

Who should test their B12 levels?

Vegans, vegetarians, older adults, people with gastrointestinal disorders or who have had stomach surgery, as well as those experiencing fatigue, weakness, memory problems, or neurological symptoms should consider a B12 test.

When should I take the test?

It is recommended to take the test on an empty stomach in the morning for the most accurate results.

How quickly will I get my results?

Once we have received your sample, the average turnaround time is 10-15 business days to receive results.
