Solgar Psyllium Husks Fiber 500 mg
Brand: Solgar · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Solgar Psyllium Husks Fiber 500 mg is a source of dietary fiber, but data on its specific ingredient composition is limited. For the ingredient calcium, which is listed on some fiber supplement labels, the data confirms a role in bone health and nerve function [NIH ODS]. However, the specific amount of calcium in this product is not provided, so we cannot evaluate its contribution to your daily needs.
How it works
Think of psyllium husk as a bulk-forming fiber that absorbs water in your digestive tract, helping to promote regularity and support healthy bowel movements. For calcium, the mechanism involves bone mineralization — it helps deposit minerals into your bone matrix for strength — and neuromuscular relaxation, supporting proper muscle and nerve signaling [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplement categories, but specific report counts for this product are not available. For calcium, the data notes that high intakes might increase the risk of heart disease and prostate cancer. Very high levels can cause constipation, nausea, weight loss, extreme tiredness, poor kidney function, and abnormal heart rhythms [NIH ODS]. Interactions include reduced absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start with a low dose of this fiber supplement, taken with a full glass of water, and increase gradually to avoid digestive discomfort. If you are taking any medications, separate the fiber supplement by at least two hours to prevent absorption issues. For calcium, the data does not provide specific dosing for this product, so consult your healthcare provider before adding it to your routine [NIH ODS].
