Muscle Feast Collagen Unflavored

Our assessment

The evidence shows that Muscle Feast Collagen Unflavored contains calcium, a mineral essential for bone health and muscle function. However, we need to be clear: the data provided does not specify the amount of calcium per serving or any other ingredients in this product [NIH ODS]. For a general audience, calcium is well-documented, but without a specific dose, we cannot confirm if this product meets your daily needs.

How it works

Calcium acts as a master regulator for your body. It supports bone mineralization, helping to build and maintain strong bone density, and it aids neuromuscular relaxation, which means it helps your muscles relax and your nerves send signals properly [NIH ODS]. Think of it as the key that unlocks proper muscle and nerve function.

Safety profile

FDA received 592,059 total adverse event reports across all supplements, but specific report counts for this product are not available. For calcium itself, high intakes may increase the risk of heart disease and prostate cancer. Very high blood and urine 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 also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

We recommend you check the label for the exact calcium content per serving, as this data is missing. If you are taking any medications, especially antibiotics or thyroid medication, take this supplement at least two hours apart to avoid absorption issues [NIH ODS]. For general bone health, ensure your total daily calcium from all sources does not exceed the safe upper limit. Consult your pharmacist or doctor before starting any new supplement.

• 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.
