Nature's Plus Shot-O-B12 5000 mcg
Brand: Nature's Plus · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this product contains 5000 mcg of vitamin B12, a water-soluble vitamin. For most adults, this is a high dose, but the data indicates that excess B12 is typically excreted in urine. However, we must be clear: the specific safety data for this exact product is limited, and the overall FDA database for all supplements shows 592,059 total adverse event reports [FDA data].
How it works
Think of vitamin B12 as a cellular energizer. It plays a key role in nerve function and the formation of red blood cells. The ingredient calcium is also listed on the label, which supports bone mineralization and neuromuscular relaxation [NIH ODS].
Safety profile
Data not available for specific side effects of this exact product. However, for the ingredient calcium, high intakes might increase the risk of heart disease and prostate cancer, and can cause constipation, nausea, and abnormal heart rhythms [NIH ODS]. The FDA has received 592,059 total adverse event reports across all supplement categories [FDA data].
Our recommendation
Start by consulting your doctor to confirm you need high-dose B12. If you have a known deficiency, this product may be appropriate. Be aware that calcium can reduce the absorption of medications like tetracycline antibiotics and levothyroxine, so take it at a different time [NIH ODS].
