Metagenics Intrinsi B12/Folate
Brand: Metagenics · Form: TABLET [E0155]
Our assessment
The evidence shows that Metagenics Intrinsi B12/Folate is a targeted supplement for supporting vitamin B12 and folate levels. However, you should be aware that the available data on this specific product is limited, and our assessment must rely on the ingredient information provided. The product contains calcium, but specific data on B12 and folate from the provided sources is not available for this formulation.
How it works
Think of calcium as a structural support for your bones and a nervous system regulator. It supports bone mineralization and density, and it helps with muscle relaxation and nerve signaling [NIH ODS]. For the B12 and folate components, specific mechanistic data was not provided in the data set.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements, though specific report counts for this product are not available. For the calcium component, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Use this product only if you have a confirmed need for B12, folate, or calcium supplementation. Be cautious with additional calcium from other sources, as high intakes carry significant risks [NIH ODS]. Check with your doctor about potential interactions with any medications you take. Data on the specific B12 and folate dosages in this product is not available, so verify the label for exact amounts before use.
