Michael's Naturopathic Programs Fiber & More

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health and nerve function. However, the data we have is incomplete for the specific "Fiber & More" formula, as the full ingredient list is labeled "See label." Our assessment is based solely on the calcium component provided. For general bone support, calcium is well-established, but you must consider your total daily intake from all sources to avoid exceeding safe levels [NIH ODS].

How it works

Think of calcium as a building block for your skeleton and a messenger for your muscles and nerves. It supports bone mineralization, meaning it helps deposit minerals into your bone matrix to keep them dense and strong. It also plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves properly signal after they fire [NIH ODS].

Safety profile

Data not available for this specific product's side effects. However, for calcium supplements in general, high intakes can lead to serious risks. Some research suggests high calcium 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]. The FDA has received 592059 total adverse event reports across all dietary supplements, but this number is not specific to this product [FDA data].

Our recommendation

Before taking this supplement, you need to know the exact amount of calcium per serving. If the label is unavailable, we cannot recommend using it. If you do have the label, ensure your total daily calcium intake from food and supplements does not exceed the tolerable upper limit. Also, be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, so take this supplement at a different time of day than those drugs [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.
