ProCaps Laboratories Vitamin B12-100
Brand: ProCaps Laboratories · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this product contains calcium, not vitamin B12 as the name suggests. For calcium, our assessment is that it is a well-supported mineral for bone health, but you must be careful with dosing and interactions. The data confirms that calcium supports bone density and mineralization [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. For you, this means it helps maintain strong bones and supports proper muscle function.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high blood and urine levels include 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 [NIH ODS]. Calcium can also reduce absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Because the label lists calcium instead of vitamin B12, you should verify the product you have. For calcium, start with dietary sources first. If you take supplements, be aware of the interactions with other medications listed above [NIH ODS]. Do not exceed recommended intakes without medical supervision.
