GrassrootsHealth collects information about supplemental intake amounts for a number of nutrients on its health and lifestyle questionnaire. In previous blogs we showed how much supplemental vitamin C, calcium, vitamin K2, and vitamin B6 GrassrootsHealth participants report taking. In today’s blog we will summarize reported intake amounts of supplemental vitamin B12.

What is Vitamin B12?

Vitamin B12, also known as cobalamin, is a vitamin most well known for its roles in helping to make red blood cells, maintaining proper nerve function, and maintaining normal levels of homocystein in the blood. Vitamin B12 is found in seafood, poultry, and red meat; deficiency is common among older adults and vegans, as well as among those with gastro-intestinal disorders or who regularly take antacids. Symptoms of deficiency may include tingling and numbness in the extremities, nerve damage, anemia, and memory loss. The recommended dietary allowance (RDA) for vitamin B12 ranges from 0.4 mcg/day for infants to 2.4 mcg/day for teenagers and adults.

Vitamin B12 Intake Among GrassrootsHealth Participants

Among participants who reported a value for supplemental vitamin B12, 58% reported taking some and 42% reported not taking any. The chart below shows the distribution of average daily supplemental vitamin B12 intake amounts for almost 3,000 participants.

Among those taking a vitamin B12 supplement, the median intake amount was 250 mcg/day. About one-third (31%) report taking less than 100 mcg/day, about one-third (35%) report taking between 100 and 999 mcg/day, and about one-third (34%) report taking 1,000 mcg/day or more.

Next, we will explore whether supplemental vitamin B12 intake affects vitamin D levels.

Will Your D Level Help Prevent Flu?

Your immune system needs vitamin D to be strong and healthy.  Make sure you know your vitamin D level, and take steps to keep it within a target of 40-60 ng/ml or 100-150 nmol/L!  Through GrassrootsHealth Nutrient Research Institute, you can also test your essential elements magnesium, copper, zinc and selenium, toxins such as lead, mercury and cadmium, as well as your omega-3 levels, inflammation levels and thyroid stimulating hormone (TSH) level.

To help you track your supplement use and nutrient levels, GrassrootsHealth has created the Personal Health Nutrient Decision System called

 

For each specific supplement, you can track what days you take it, how much, and many other details. This will help you know your true supplemental intake and what patterns of use work for you to reach and maintain optimum nutrient levels. Check it out today!

How Can You Use this Information for YOUR Health?

Having and maintaining healthy vitamin D and other nutrient levels can help improve your health now and for your future. Measuring is the only way to make sure you are getting enough!

STEP 1 Order your at-home blood spot test kit to measure vitamin D and other nutrients of concern to you, such as omega-3s, magnesium, essential and toxic elements (zinc, copper, selenium, lead, cadmium, mercury); include hsCRP as a marker of inflammation or HbA1c for blood sugar health

STEP 2 Answer the online questionnaire as part of the GrassrootsHealth study

STEP 3 Using our educational materials and tools (such as our dose calculators), assess your results to determine if you are in your desired target range or if actions should be taken to get there

STEP 4 After 3-6 months of implementing your changes, re-test to see if you have achieved your target level(s)
