NeoCell Super Collagen+C

Our assessment

The evidence shows that NeoCell Super Collagen+C is a supplement providing collagen and vitamin C, but the data available for its key mineral component, calcium, requires careful consideration. Data not available for the specific collagen or vitamin C content of this product. For the calcium component, our assessment is that the RDA for most adults is 1,000 to 1,200 mg daily from all sources [NIH ODS]. You should evaluate your total calcium intake from food and supplements to avoid exceeding safe levels.

How it works

Think of calcium as a structural building block for your skeleton. It supports bone density and mineral deposition [NIH ODS]. Additionally, calcium plays a role in neuromuscular relaxation, supporting muscle relaxation and nerve signaling [NIH ODS]. The vitamin C in the product is involved in collagen synthesis, which may support the health of your skin, joints, and connective tissues.

Safety profile

FDA received 592,059 total adverse event reports for products in this category [FDA data]. For the calcium component specifically, some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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

Start by calculating your daily calcium intake from all sources, including food. If you are already meeting your needs through diet, you likely do not need additional calcium from this supplement. Take calcium supplements with food to improve absorption, and do not exceed the tolerable upper intake level of 2,500 mg per day from all sources [NIH ODS]. If you take any of the medications listed above, separate your calcium dose by at least two hours [NIH ODS]. Data not available for the specific dosage of collagen or vitamin C in this product.
