Douglas Laboratories Multi-Probiotic 15 Billion
Brand: Douglas Laboratories · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that Douglas Laboratories Multi-Probiotic 15 Billion is a product that contains calcium, but specific data on this probiotic blend’s efficacy is not available in the provided data. We must focus on the calcium component, as that is the only ingredient with detailed information. Calcium is a well-studied mineral for bone health, but it is not a probiotic, so this product’s primary label claim is not supported by the data we have [NIH ODS].
How it works
When you take calcium from this product, it acts as a key structural component for your skeleton. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. However, since the product is marketed as a probiotic, you should know that the data does not provide any mechanism or evidence for probiotic benefits for this specific product.
Safety profile
FDA has received 592,059 total adverse event reports for all dietary supplements, but specific report counts for this product are not available. For the calcium component, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine calcium levels can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Based on the data provided, we cannot recommend Douglas Laboratories Multi-Probiotic 15 Billion as a probiotic because no probiotic-specific data was supplied. If you are taking this for the calcium, proceed with caution. Check your total calcium intake from all sources, and take this product at least two hours apart from any medications listed above. For probiotic benefits, data is not available for this product, so you may want to consult your healthcare provider for a product with documented probiotic strains [NIH ODS].
