Nature's Sunshine Probiotic Eleven
Brand: Nature's Sunshine · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Nature's Sunshine Probiotic Eleven contains calcium as a key ingredient. Our assessment is that while calcium is essential for bone health, you should be aware of the specific risks and interactions associated with supplementation. The data for this product is limited to its ingredient list, so we will focus on the calcium component.
How it works
Calcium acts as a master regulator for your body's structural and signaling systems. It supports bone mineralization and density, and it also promotes neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
There have been 592,059 total adverse event reports across all supplements in the FDA database. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Side effects from high levels in the blood and urine 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 [FDA data] [NIH ODS].
Our recommendation
You should be cautious with calcium supplementation. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. We recommend you speak with your healthcare provider before using this product, especially if you take any of those medications or have a history of kidney issues or heart disease.
