Our assessment
The evidence shows that this product, HARD RHINO Pure Vitamin B12 Cyanocobalamin 1% Pure Powder, contains the ingredient calcium. However, the specific dose per serving is not provided in the data, which is a critical limitation. Based on the available information, calcium is essential for bone health, but the lack of dosing details for this specific product makes it impossible to offer a precise recommendation. Data not available for the intended use of this specific product [NIH ODS].
How it works
Think of calcium as a structural builder and a cellular messenger. It supports bone mineralization by helping deposit minerals into your skeleton, and it plays a key role in neuromuscular relaxation, allowing your muscles to relax and your nerves to signal properly after contraction [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, potential side effects from high intakes include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms. High blood and urine levels of calcium can also lead to poor muscle tone, poor kidney function, and a high risk of death from heart disease [FDA data] [NIH ODS]. Calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Because the exact dosage of calcium in this product is not provided in the data, we cannot recommend it as a reliable source for meeting your calcium needs. If you are considering a calcium supplement, first check your total intake from food and other supplements. For general health, aim for the RDA from dietary sources when possible, and consult your healthcare provider before adding any new supplement, especially if you take prescription medications [NIH ODS].
