Moss Nutrition B12 Methylfolate Select Natural Berry Lozenge

Our assessment

The evidence shows that this product contains two well-studied nutrients, but the specific formulation of Moss Nutrition B12 Methylfolate Select Natural Berry Lozenge is not fully detailed in the data provided. Based on the ingredients, you are getting a combination of vitamin B12 and methylfolate, which are critical for energy metabolism and cell division. However, data on this exact branded product is limited.

How it works

Think of these ingredients as cellular fuel. Methylfolate is the active form of folic acid, which your body uses to produce red blood cells and support DNA synthesis. Vitamin B12 works alongside it to maintain nerve health and help convert food into energy. The natural berry lozenge is designed for sublingual absorption, which may help bypass digestive issues for people with absorption problems.

Safety profile

Data not available for this specific product. The FDA has received a total of 592,059 adverse event reports across all supplement categories, but no specific side effect counts are provided for this product or its individual ingredients (B12 and methylfolate) in the data you supplied. High calcium intake, which is not relevant here, can cause constipation, nausea, and abnormal heart rhythms [NIH ODS]. No specific side effects for B12 or methylfolate were listed in the provided data.

Our recommendation

Because the data does not include specific dosage information, efficacy studies, or side effect reports for this product, we cannot make a confident recommendation at this time. If you are considering this supplement for a known B12 or folate deficiency, consult your healthcare provider for a blood test first. The total FDA data shows that supplement use carries some risk, but without product-specific data, we cannot assess this lozenge’s safety profile [FDA data].
