Our assessment
Metamucil MultiHealth Fiber Psyllium Fiber Capsules + Calcium is a combination product. The evidence shows that the calcium in this supplement supports bone mineralization and nerve signaling [NIH ODS]. However, the data on psyllium fiber is limited in the information provided. Our assessment is that you should be aware of the specific risks and interactions associated with the calcium component.
How it works
Think of calcium as a structural building block for your bones. It supports bone density and mineral deposition, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. This is why getting enough calcium is critical for maintaining strong bones and proper muscle function.
Safety profile
FDA received a total of 592,059 adverse event reports for products in this database. For the calcium component specifically, the data notes that high calcium 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].
Our recommendation
Be cautious with this product, especially if you are taking other calcium supplements or medications. Calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Do not exceed the recommended dose. If you have a history of kidney stones, heart disease, or prostate cancer, consult your doctor before use.
