Dr. David Williams Probiotic Advantage
Brand: Dr. David Williams · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that Dr. David Williams Probiotic Advantage contains Calcium. Data on this specific product is limited, but we can assess the primary ingredient. Calcium is a critical mineral for bone health and nerve function [NIH ODS]. However, you should be aware of the risks associated with high intake, as the data does not support routine supplementation for everyone [NIH ODS].
How it works
Think of calcium as a structural builder and signaler for your body. It supports bone mineralization and density, and it helps your muscles relax and your nerves send signals properly [NIH ODS]. This ingredient works alongside other nutrients to maintain your body's foundational structure and communication systems [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all products. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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 several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by evaluating your dietary calcium intake from food sources before adding this supplement. If you take this product, follow the label direction and do not exceed the recommended dose. You should also separate your dose from any medications by at least two hours, especially those listed for drug interactions [NIH ODS]. Always consult your healthcare provider before starting a new supplement, particularly if you have a history of kidney stones or heart conditions [NIH ODS].
