Our assessment
The evidence shows that Nature's Sunshine Liquid - Methyl Vitamin B12 Complete contains Calcium, a mineral essential for bone health. Our assessment: this product may help support your bone density and nerve function, but you need to be aware of potential risks if you take high doses or have certain health conditions [NIH ODS].
How it works
Think of calcium as a structural builder for your bones. It supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA has received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels in your blood or urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [FDA data] [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start with the dosage listed on the label. Be cautious if you take any of the medications listed above, and separate calcium intake by at least two hours. If you have kidney disease, a history of heart problems, or prostate cancer concerns, consult your doctor before use. Data not available for specific dosage recommendations for this liquid form [NIH ODS].
