Our assessment
The evidence shows that Simply Right Fiber Capsules contain **calcium**, a mineral essential for bone health and nerve function. Our assessment is that while calcium is a critical nutrient, you need to be aware of the specific risks and interactions before adding this supplement to your routine [NIH ODS].
How it works
Think of calcium as a structural builder and a signal messenger. It supports bone density and mineral deposition, which is key for strong bones. It also assists in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports for this product category. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High levels in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by checking your current calcium intake from food and other supplements. Because of the potential for serious side effects and drug interactions, you should only use this product if you have a confirmed need. Do not exceed the RDA without medical supervision, and always take it separately from medications listed above [NIH ODS].
