Our assessment
The evidence shows that Douglas Laboratories Multi-Probiotic 40 Billion is a supplement containing calcium. Based on the data provided, we can only assess the calcium component. Our assessment is that calcium is essential for bone health, but you need to be aware of specific risks and interactions [NIH ODS].
How it works
Think of calcium as a building block for your skeleton and a signaling molecule for your nerves and muscles. It supports bone mineralization and density, and it is critical for neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports for all supplements combined. Data not available for specific side effect reports for this product. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels in the blood 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] [FDA data]. Calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Because this product contains calcium, take it at least 2 hours apart from any medications you may be using, especially thyroid medication or antibiotics. If you have a history of kidney stones or heart disease, consult your doctor before use. Data not available on the specific probiotic strains or their benefits in this product [NIH ODS].
