Solgar Vitamin B12 100 mcg
Brand: Solgar · Form: TABLET [E0155]
Our assessment
Our assessment: The evidence shows that Solgar Vitamin B12 100 mcg is a targeted dose for supporting nerve health and energy metabolism. However, it is important to note that the primary ingredient in the data provided is Calcium, not Vitamin B12. For calcium, the data indicates a role in bone mineralization and neuromuscular relaxation [NIH ODS]. You should verify the product label to confirm it contains B12, as the specific ingredient data for B12 is not available here.
How it works
Think of calcium as a structural builder and a signal regulator. It supports bone density through mineral deposition and helps your muscles relax and nerves signal properly [NIH ODS]. If the product is indeed Vitamin B12, it typically supports red blood cell formation and neurological function, but specific mechanism data for B12 is not provided in this dataset.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements in this dataset. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer, and can cause side effects such as constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms [NIH ODS] [FDA data]. Data for side effects of Vitamin B12 at this specific dose is not available.
Our recommendation
Our recommendation: Start by confirming the product label to ensure it contains Vitamin B12 as intended. If you are taking this for calcium, be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Talk to your healthcare provider before starting any new supplement, especially if you take prescription medications.
