Our assessment
The evidence shows that Nature's Sunshine Intestinal System Probiotic Eleven contains calcium, a mineral essential for bone health. However, our assessment is that the specific health benefits of this product depend entirely on the complete ingredient list, which is marked as "See label" and is not fully provided in the data. For the calcium component, the data is clear: it supports bone mineralization and neuromuscular relaxation [NIH ODS]. You should consult the product label for the full list of ingredients to understand what you are taking.
How it works
Think of calcium as a structural builder for your skeleton. It works by supporting bone density and mineral deposition, which is crucial for maintaining strong bones as you age. Additionally, calcium plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after activity [NIH ODS]. For a probiotic product, the specific mechanism for digestive health would depend on the bacterial strains listed on the label, which are not provided in the data.
Safety profile
Safety data is based on the calcium ingredient. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels in the blood and urine 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]. The FDA has received a total of 592,059 adverse event reports across all supplement categories, but a specific report count for this product is not available [FDA data]. You should also know that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Our recommendation is to check the product label for the complete ingredient list and the specific probiotic strains included. For the calcium component, do not exceed the RDA without consulting your doctor, especially if you have a history of kidney disease or heart conditions. Take calcium supplements separately from your other medications to avoid absorption issues [NIH ODS]. If you are looking for a probiotic, data on the specific bacterial strains in this product is not available, so you should compare it with other products that list their strains and colony-forming units (CFUs) clearly.
