Natrol Probiotic High Potency

Our assessment

The evidence shows that calcium is a critical mineral for bone health, but the data on Natrol Probiotic High Potency is limited to the ingredients listed. Our assessment is that this product contains calcium, which plays a key role in bone mineralization and neuromuscular relaxation [NIH ODS]. However, we must be transparent: specific data on the probiotic strains themselves is not available in the provided information.

How it works

Think of calcium as a structural building block for your bones. It supports bone density and mineral deposition, and it also helps your muscles relax and your nerves signal properly [NIH ODS]. If you are taking this probiotic for digestive health, note that the provided data does not include studies on probiotics from the list you supplied.

Safety profile

FDA received 592,059 total adverse event reports across all supplements, but specific reports for this product are not available. For calcium, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high calcium levels include 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 medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

If you are using this supplement for calcium, be mindful of your total daily intake from all sources. Start by checking your current calcium consumption from food and other supplements to avoid excessive levels [NIH ODS]. Because specific probiotic study data is not available, we cannot confirm any digestive health benefits for this product. Our recommendation is to consult your healthcare provider, especially if you take any of the medications listed above, to ensure safe use.
