Metagenics Intrinsi B12/Folate
Brand: Metagenics · Form: TABLET [E0155]
Our assessment
The evidence shows that Metagenics Intrinsi B12/Folate is a targeted supplement designed to support healthy levels of vitamin B12 and folate. While the product label lists these ingredients, the data provided focuses on calcium, not B12 or folate. For calcium, our assessment is that this mineral is essential for bone health, but you need to be careful with dosing to avoid risks [NIH ODS].
How it works
Think of calcium as a structural builder for your bones and a signal conductor for your nerves. It supports bone mineralization and density, and it also helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements in their database. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels in your blood or urine can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you choose to take Metagenics Intrinsi B12/Folate, follow the label directions. For calcium, if it is part of your regimen, do not exceed the recommended intake without medical supervision. Be aware of potential interactions with your prescription medications, and always discuss new supplements with your pharmacist or doctor [NIH ODS].
