Global Healing Vitamin B12 5000 mcg
Brand: Global Healing · Form: LIQUID, SUPPLEMENT FORM [E0165] On Market
Our assessment
The evidence shows that the primary active ingredient in this product is calcium, not vitamin B12 as the name might suggest. For calcium, the data supports its role in bone health, but the high dose is a concern. Our assessment: you should not take this product without a clear medical need, as the risks may outweigh the benefits for most people [NIH ODS].
How it works
Think of calcium as a structural architect for your bones and a signal messenger for your nerves and muscles. It supports bone mineralization and density, and it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports across all supplements. For calcium specifically, high intakes can increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high blood or urine levels include 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 medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by getting your calcium from food. If you must supplement, choose a dose of 500-600 mg or less, and take it with food. Do not exceed the Tolerable Upper Intake Level unless directed by your doctor [NIH ODS]. Data for vitamin B12 at 5000 mcg is not available in the provided data set.
