Nature's Way Liquid Fiber Sugar Free Orange

Our assessment

The evidence shows that this product contains calcium as its primary ingredient, which is widely recognized for its role in bone health. However, it is important to note that this supplement is labeled as a fiber product, and the data provided does not confirm the amount or type of fiber present. Our assessment is that you should verify the specific calcium dosage on the label and consider whether a fiber supplement is truly your primary need, as the data focuses on the mineral calcium rather than fiber content [NIH ODS].

How it works

Think of calcium as a structural building block for your bones. It supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. While the product is marketed as a fiber supplement, the data only provides details on calcium, so its function as a fiber source is not supported by the information given.

Safety profile

FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product or its exact side effects are not available. Based on the calcium data, high intakes might increase the risk of heart disease and prostate cancer. 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]. Additionally, calcium can reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

We recommend that you check the product label for the exact calcium dosage and fiber content, as this data is not provided. If you are taking any medications, particularly antibiotics or thyroid medication, take this supplement at a different time of day to avoid absorption issues [NIH ODS]. Start with the lowest effective dose and consult your healthcare provider to ensure this product meets your specific health needs, especially since the primary data available is for calcium, not fiber [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.
