Country Life Methyl B12 3000 mcg Berry Flavor

Our assessment

The evidence shows that this product, Country Life Methyl B12 3000 mcg Berry Flavor, contains one key ingredient for which we have data: Calcium. However, the provided data does not confirm the presence or absence of Methyl B12, so we cannot assess that ingredient. For calcium, the data supports its role in bone health, but you should be aware of specific safety considerations and potential medication interactions [NIH ODS].

How it works

Think of calcium as a structural builder for your skeleton. It works by supporting bone density and mineral deposition, which is crucial for maintaining strong bones. Additionally, it plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].

Safety profile

For the calcium in this product, safety data shows that high intakes might increase the risk of heart disease and prostate cancer. Very high levels of calcium 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]. The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product or its ingredients are not available [FDA data].

Our recommendation

Because the data does not confirm the presence of Methyl B12 in this product, we cannot recommend it based on that claim. If you are taking calcium for bone health, be aware that it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available on the berry flavor or other ingredients. We recommend consulting your healthcare provider before starting this supplement, especially if you take any of the listed medications.
