New Sun Fiber Cleanse

Our assessment

The evidence shows that New Sun Fiber Cleanse contains Calcium as an ingredient. Our assessment: this product does not provide any unique or proven benefits for "fiber cleansing" based on the data provided. The only active ingredient data available is for calcium, which is a mineral for bone health, not a fiber or a cleanser [NIH ODS]. You should be aware that this product's name may be misleading regarding its actual function.

How it works

Calcium primarily works through two mechanisms: Bone mineralization, where it supports bone density and mineral deposition, and Neuromuscular relaxation, where it supports muscle relaxation and nerve signaling [NIH ODS]. Data not available on how this specific product acts as a "fiber cleanse."

Safety profile

FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, some research suggests that 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]. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

We cannot recommend New Sun Fiber Cleanse for "cleansing" purposes, as no data supports this claim. If you are seeking calcium supplementation, be cautious with dosage. Avoid taking this product within 2 hours of any medications listed above to prevent absorption issues [NIH ODS]. Given the potential risks of high calcium intake and the lack of data for this product's intended use, our recommendation is to avoid this supplement and focus on a balanced diet for your fiber and mineral needs [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.
