Brand: Reserveage Nutrition · Form: POWDER [E0162] On Market
Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health, but the data does not confirm the specific benefits of this collagen powder formulation. Our assessment is that you should understand the role of calcium before considering this supplement, as the collagen-specific effects are not supported by the data provided.
How it works
Calcium works through bone mineralization to support bone density and mineral deposition, and through neuromuscular relaxation to support muscle relaxation and nerve signaling [NIH ODS]. Think of calcium as a building block your body uses to keep your skeleton strong and your nerves communicating properly.
Safety profile
Data not available for this specific product's side effects. However, FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High levels 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
We recommend you get your calcium needs met through food first, as the data does not support the collagen powder form. If you choose to supplement, be aware of the serious risks from high intakes and the medication interactions listed above. Consult your healthcare provider before starting, especially if you take any prescription medications [NIH ODS].
