Our assessment
The evidence shows that while calcium is essential for bone health, the specific product you asked about — Dr. Mercola Methyl B12 Energy Boost — does not contain calcium as a listed ingredient. Data on this specific product’s benefits is not available. For general calcium guidance: the mineral supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural builder for your bones and a signal regulator for your nerves. It supports bone density through mineral deposition and helps muscles relax after contraction [NIH ODS]. Your body tightly controls calcium levels in the blood, but supplementing can raise those levels if you take too much [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories, but specific report counts for calcium alone are not available. High levels of calcium in the blood and urine can cause 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 absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Because the Dr. Mercola Methyl B12 Energy Boost product does not contain calcium, our recommendation for calcium specifically is to get your intake from food sources first. If you do use a calcium supplement, take it separately from your thyroid medication or antibiotics by at least two hours to avoid interaction [NIH ODS]. For this specific product, data on its benefits and risks is not available, so consult your healthcare provider before use.
