Lee Haney's Nutritional Support Systems Herbal Laxative High Potency Fiber Complex

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health. For a general audience seeking digestive support, it is important to understand that the primary active ingredient for laxative and fiber effects is not calcium. Our assessment is that you should not rely on this product for calcium supplementation without understanding the specific dose per serving, which is data not available from the provided information.

How it works

Calcium supports bone mineralization by helping deposit minerals into your skeleton and aids neuromuscular relaxation, which is important for proper nerve signaling and muscle function [NIH ODS]. As a fiber complex, the product is designed to support regularity, though specific mechanism data for the fiber blend is not available in the provided materials.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. High blood and urine calcium 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 reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

We recommend you check the product label for the exact calcium content per serving, as that data is not provided here. If you are taking any prescription medications, particularly antibiotics or thyroid medication, take this supplement at least two hours apart to avoid absorption interference [NIH ODS]. For general bone health, the evidence supports obtaining calcium primarily from food sources, and you should not exceed the tolerable upper intake level without medical supervision [NIH ODS].

Supplement labels contain several key sections regulated by the FDA:

• Serving Size — The recommended amount per dose. Always check this — some products require multiple capsules per serving.
• Amount Per Serving — Shows the quantity of each nutrient in the product, typically in IU (International Units), mg (milligrams), or mcg (micrograms).
• % Daily Value (%DV) — Indicates how much a nutrient in a serving contributes to a daily diet. 5% DV or less is low; 20% DV or more is high.
• Other Ingredients — Lists inactive ingredients like fillers, binders, and capsule materials (e.g., gelatin, cellulose, magnesium stearate).
• Suggested Use — The manufacturer's recommended directions for taking the supplement, including timing and dosage.
