GNC Women's Collagen
Brand: GNC · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that GNC Women’s Collagen contains calcium, a mineral with well-documented benefits for bone health. For you, this means the product may support your skeletal strength and muscle function, but it is important to understand the specific role of this ingredient. Data not available on the total amount of calcium per serving from the product label, so you must check the label to determine if the dose is appropriate for your needs [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a key player in your nervous system. It supports bone mineralization, which helps maintain bone density, and it aids neuromuscular relaxation, which helps your muscles and nerves signal properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, the data shows that high intakes might increase the risk of heart disease and prostate cancer. Side effects from excessive calcium can include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease. You should also be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [FDA data] [NIH ODS].
Our recommendation
Check the label on GNC Women’s Collagen to confirm the exact calcium content per serving. If you take other medications, take this supplement at least two hours apart from them. Do not exceed the recommended dietary allowance for calcium from all sources combined. If you have a history of kidney stones, heart disease, or prostate cancer, consult your doctor before starting this product [NIH ODS].
