Our assessment
The evidence shows that GNC SuperFoods Ultra Mega Green Men's Energy & Metabolism contains calcium as a key mineral. For you, this means you are getting a nutrient that plays a critical role in bone health and muscle function. Our assessment is that this product can help you meet your daily calcium needs, but you must be aware of the specific risks and interactions tied to this ingredient [NIH ODS].
How it works
Think of calcium as a structural and signaling powerhouse in your body. It supports bone mineralization, which is the process of building and maintaining strong, dense bones. It also helps your muscles relax properly and assists with nerve signaling, both of which are essential for your energy and metabolism throughout the day [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Symptoms of excessive calcium in your blood include constipation, nausea, weight loss, extreme tiredness, abnormal heart rhythms, and poor kidney function [NIH ODS] [FDA data]. The product also carries a risk of interacting with medications like antibiotics (tetracyclines and fluoroquinolones), bisphosphonates for bone health, and thyroid medication (levothyroxine) [NIH ODS].
Our recommendation
We recommend you check your total daily calcium intake from all sources, including food and other supplements, to avoid exceeding safe levels. If you take any prescription medications, particularly for thyroid conditions or infections, take this supplement at a different time of day to prevent absorption issues. Data not available on the exact calcium dosage in this specific product, so consult the label carefully [NIH ODS].
