Natures Plus Vitamin B12 1000 mcg
Brand: Natures Plus · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that this product’s active ingredient—calcium—plays a foundational role in bone health, but the data does not support using it for any other condition in a general healthy adult. Natures Plus Vitamin B12 1000 mcg is labeled as containing calcium as an ingredient, and the data we have applies to calcium, not vitamin B12. Data for vitamin B12 itself is not available. Our assessment: calcium is well-supported for bone mineralization, but the specific benefits of this product depend on whether you actually need additional calcium [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, and it also plays a role in neuromuscular relaxation—helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels 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 the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Before taking this supplement, check your dietary calcium intake. Most adults get enough from food. If you do need a supplement, start with a low dose and take it with food. Always separate calcium from thyroid medication or antibiotics by at least 4 hours [NIH ODS]. Because the product label lists "Natures Plus Vitamin B12 1000 mcg" but the only ingredient data provided is for calcium, we cannot confirm the vitamin B12 content or its effects. Speak with your doctor before starting this supplement [FDA data] [NIH ODS].
