Brand: Douglas Laboratories · Form: LOZENGE [E0174] On Market
Our assessment
The evidence shows that Douglas Laboratories Vitamin B12 is a straightforward supplement. For a general audience, vitamin B12 is essential for nerve function and red blood cell formation. However, based on the data provided, we cannot make a specific claim about this product's effectiveness because no specific data on its ingredients or clinical studies was provided. The data only includes information on calcium, not vitamin B12. Therefore, our assessment is limited: if you are looking for a B12 supplement, this product may be suitable, but we cannot confirm its benefits from the given information.
How it works
While the data provided does not include information on vitamin B12, we can explain the role of calcium, which is listed in the data. Calcium supports bone mineralization by helping deposit minerals into bone tissue, and it aids neuromuscular relaxation by supporting nerve signaling and muscle function [NIH ODS]. For vitamin B12 specifically, data is not available in the provided materials.
Safety profile
The FDA adverse event database contains a total of 592,059 reports across all supplements, but no specific report count for Douglas Laboratories Vitamin B12 is provided. For calcium, which is the only ingredient with safety data, high intakes can cause constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. High calcium levels in the blood and urine may also increase the risk of heart disease and prostate cancer [NIH ODS]. Additionally, calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. For vitamin B12 side effects, data is not available.
Our recommendation
Based on the data, we cannot make a specific recommendation for Douglas Laboratories Vitamin B12 due to missing information on its ingredients and clinical studies. If you are considering this supplement, consult your healthcare provider, especially if you take medications that may interact with calcium (if the product contains calcium). For general health, ensure you meet your B12 needs through diet or a trusted supplement. Data for a more detailed recommendation is not available.
