CytoSport Monster Series Monster Amino 6:1:1 Grape

Our assessment

Our assessment: The evidence shows that the calcium in CytoSport Monster Series Monster Amino 6:1:1 Grape is a mineral primarily known for bone health, but the data does not support using this product for muscle-building or amino acid support. You should be aware that calcium supplements carry specific risks, and the reported benefits are limited to bone mineralization and nerve signaling [NIH ODS].

How it works

Think of calcium as a structural builder — it supports bone density and mineral deposition, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. The product label does not provide specific dosage information for the calcium content, so you cannot verify how much you are actually getting from each serving.

Safety profile

The FDA received 592,059 total adverse event reports across all supplements, though specific report counts for calcium alone are not available in the provided data [FDA data]. 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]. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Data not available to support a specific dosage for this product. Because the product label information is incomplete, we cannot recommend CytoSport Monster Series Monster Amino 6:1:1 Grape for calcium supplementation. If you need calcium, choose a supplement with a clearly stated dose on the label and talk to your doctor about your individual needs, especially if you take any medications that interact with calcium [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.
