21st Century Psyllium Fiber
Brand: 21st Century · Form: CAPSULE [E0159]
Our assessment
The evidence shows that 21st Century Psyllium Fiber is a fiber supplement, but the data provided does not include specific information about psyllium itself. Our assessment is based on the ingredient listed in the NIH ODS data: Calcium. If this product contains calcium, you should be aware of its effects on bone health and potential risks. For psyllium-specific benefits, data is not available in the provided information.
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization, helping to deposit minerals into your skeleton for density and strength. It also plays a role in neuromuscular relaxation, ensuring your muscles and nerves signal properly [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might 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 need to urinate, 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
If you are taking 21st Century Psyllium Fiber for its fiber content, note that specific data on psyllium is not available here. If the product contains added calcium, do not exceed recommended intakes without medical supervision. Take calcium supplements at least 2 hours apart from medications like thyroid hormones or antibiotics to avoid absorption issues. Always consult your pharmacist or doctor before adding this supplement to your routine [NIH ODS].
