Nature Made Vitamin B12 1000 mcg
Brand: Nature Made · Form: SOFTGEL CAPSULE [E0161] On Market
Our assessment
The evidence shows that this product contains 1000 mcg of vitamin B12, which is well above the Recommended Dietary Allowance for most adults. However, based on the data provided, the primary ingredient with available safety information is calcium, not vitamin B12. Our assessment is that while the product is formulated with a high dose of B12, you should be aware that data on the specific safety profile of this B12 supplement is not available from the sources provided.
How it works
Think of vitamin B12 as a key player in your body's energy and nerve functions. It helps your red blood cells form properly and supports your nervous system. While the specific mechanism for this product is not described in the data, calcium—which is listed as a related ingredient in the data—supports bone mineralization and neuromuscular relaxation [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this exact product or for vitamin B12 alone are not available in the provided data. For calcium, which is referenced in the data, side effects at high levels include poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Data for B12-specific side effects is not available.
Our recommendation
Our recommendation is to consult your healthcare provider before starting this supplement, especially if you take medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin, as calcium supplements may reduce their absorption [NIH ODS]. Since the data does not provide specific safety information for the vitamin B12 in this product, we advise relying on professional guidance to determine if this dosage is appropriate for your individual needs.
