Our assessment
The evidence shows that the primary active ingredient in Nature's Sunshine Everybody's Fiber is calcium. Based on the data available, we cannot assess the fiber component specifically, but we can provide a thorough analysis of the calcium content. This supplement is likely best used to support bone health, but you should be aware of important safety considerations and potential medication interactions.
How it works
Think of calcium as a structural building block for your bones. It supports bone mineralization and density, and also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. This means it helps keep your skeleton strong while also supporting proper muscle and nerve function.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories, though specific reports for this product are not available. Regarding 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]. You should also know that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you are taking any medications for osteoporosis, thyroid conditions, or infections, take this supplement at least two hours apart from those medications [NIH ODS]. Start with the lowest dose on the label and do not exceed the recommended daily intake for calcium, which is 1,000–1,200 mg for most adults from all sources combined. Data not available for the fiber content or specific dosage of this product. Consult your healthcare provider before starting, especially if you have kidney issues or a history of heart disease.
