Martin Avenue Pharmacy Psyllium Fiber 500 mg
Brand: Martin Avenue Pharmacy · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that psyllium fiber is a well-studied supplement for digestive health, but the specific product "Martin Avenue Pharmacy Psyllium Fiber 500 mg" has limited data. The active ingredient, calcium, is present in this formulation, but the psyllium component itself is the primary focus for fiber benefits. For calcium, the data confirms it supports bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of psyllium as a bulk-forming laxative that helps regulate bowel movements by absorbing water and forming a gel-like substance in your gut. For the calcium component, it acts as a master regulator for bone density and muscle signaling — helping your body maintain strong bones and proper nerve function [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories, but specific data for this product is not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels can cause poor muscle tone, poor kidney function, 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 absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start with a low dose of this psyllium fiber product and increase gradually, drinking plenty of water. For the calcium component, be aware that high intakes may pose risks, so do not exceed the recommended daily allowance without medical guidance. If you take any medications, consult your pharmacist about potential calcium interactions. For specific safety data on this exact product, data is not available [NIH ODS].
