Our assessment
The evidence shows that Metagenics MetaFiber, which contains calcium, is best viewed as a supplement to support your bone health, but the data comes with important cautions. Calcium is essential for bone mineralization and neuromuscular relaxation [NIH ODS]. However, we must be straightforward: the data does not provide specific dosage information for this product, so you need to check the label carefully.
How it works
Think of calcium as a builder and regulator for your body. It supports bone density and mineral deposition, helping keep your skeleton strong, and it also aids in muscle relaxation and nerve signaling [NIH ODS]. If you are taking this supplement to address a specific deficiency or to support bone health, it can play a useful role in your daily regimen.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but specific side effect counts for this product are not available in the data provided. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by reading the label on your Metagenics MetaFiber product to confirm the exact calcium dosage. Do not exceed the recommended daily intake without medical supervision. If you take any prescription medications, separate your supplement from those doses by at least 2 hours to avoid absorption issues [NIH ODS]. Consult your healthcare provider before starting this supplement, especially if you have a history of kidney problems or heart disease [NIH ODS].
