Our assessment
The evidence shows that this product contains calcium, a mineral with a clear role in bone health, but the data provided is incomplete for a full evaluation. Based on the information available, we can only assess the calcium component. You should be aware that for the complete formula, significant data — including specific dosages, other active ingredients, and their evidence — is missing. Our assessment is therefore limited to what the data confirms about calcium.
How it works
Calcium works through two primary mechanisms. First, it supports bone mineralization, helping deposit minerals into your bone matrix to maintain density and strength. Second, it facilitates neuromuscular relaxation, playing a critical role in nerve signaling and allowing your muscles to relax after contracting [NIH ODS].
Safety profile
From a safety standpoint, the FDA has received a total of 592,059 adverse event reports for all dietary supplements. For calcium specifically, the data warns that high intakes may increase the risk of heart disease and prostate cancer. 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
Given the incomplete data — specifically, the lack of a full ingredient list, dosages, and studies for this product — we cannot confidently recommend Nature's Sunshine Probiotic Eleven. You should consult your healthcare provider before starting this supplement. If you choose to use it, be aware of calcium's potential side effects and interactions with medications. For bone health, a targeted calcium supplement with a known dose is a more evidence-based choice [NIH ODS]. Data not available for the product's other ingredients or any clinical studies.
