Moss Nutrition B12 Methylfolate Select Natural Berry Lozenge

Our assessment

The evidence shows that Moss Nutrition B12 Methylfolate Select Natural Berry Lozenge is a supplement designed to support methylation and energy production. However, based on the data provided, we cannot make specific claims about this product's effectiveness or safety because the ingredient list is marked as "See label" and no specific ingredient data was supplied for B12 or methylfolate. We must rely on the only ingredient data available: Calcium. Our assessment is that without complete ingredient information, a full evaluation is not possible, and you should consult the product label directly for a list of active ingredients and their amounts.

How it works

Based on the data provided, the only ingredient with a mechanism described is Calcium. Calcium works through bone mineralization, supporting bone density and mineral deposition, and through neuromuscular relaxation, helping muscles relax and nerves signal properly [NIH ODS]. If this product contains calcium, it would function in those ways. However, since the product is named for B12 and methylfolate, and no specific data for those ingredients is available, we cannot describe how they work in this supplement.

Safety profile

The FDA adverse event database contains a total of 592,059 reports across all supplements, but no specific report count is available for this product [FDA data]. For calcium, the data shows that high intakes might increase the risk of heart disease and prostate cancer. 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]. Calcium can also reduce the absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available for side effects specific to B12 or methylfolate in this product.

Our recommendation

Data not available to make a specific recommendation for this product. You should review the product label for a complete list of ingredients and their amounts. If you are considering this supplement, speak with your healthcare provider, especially if you take medications that interact with calcium, such as thyroid medication or antibiotics [NIH ODS]. Without ingredient-specific data, we cannot recommend a dosage or duration of use.
