Our assessment
The evidence shows that Jarrow Formulas Methyl B-12 Lemon Flavor 1000 mcg is a straightforward vitamin B12 supplement. However, the data provided is almost exclusively about calcium, not the methylcobalamin in this product. For the specific ingredient in this supplement, key data is not available. We must base our full analysis on the calcium data provided, which is not the active ingredient here.
How it works
Calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. For the vitamin B12 in this product, think of it as a key support nutrient for nerve health and red blood cell formation. Specific mechanism details for methylcobalamin are not available in the provided data.
Safety profile
Based on the calcium data provided, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High calcium levels can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms [NIH ODS]. The total adverse event reports across all supplements in the FDA database is 592,059 [FDA data]. Specific adverse event counts for this product are not available.
Our recommendation
Because the data provided does not cover the active ingredient (methylcobalamin), we cannot make a specific recommendation for Jarrow Formulas Methyl B-12. For general calcium use, be cautious of high intakes and interactions with medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Talk to your doctor to determine if this B12 supplement is right for you.
