ResVitale Collagen & Grape Seed Extract
Brand: ResVitale · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this product combines two ingredients with different levels of scientific support. For the Calcium component, data supports its role in bone mineralization and neuromuscular relaxation [NIH ODS]. However, for the Grape Seed Extract and Collagen components in this specific product, data is not available from the provided sources regarding their mechanisms or efficacy. Our assessment is that the Calcium in this formula has well-documented benefits, but you should not expect the same level of evidence for the other ingredients.
How it works
Think of the Calcium in this supplement as a structural building block for your bones. It supports bone density by aiding in mineral deposition and also helps your muscles relax and your nerves signal properly [NIH ODS]. The Grape Seed Extract and Collagen components are included in the product, but their specific mechanisms of action are not described in the data provided.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but the specific report count for this product is not available. For the Calcium ingredient specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels of calcium can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you are taking this product for bone health, the Calcium content is supported by data, but you should be aware of the potential for reduced absorption of other medications you may take. We recommend taking this supplement at least two hours apart from any prescription medications, especially antibiotics and thyroid medication [NIH ODS]. Do not exceed the recommended dose, as high calcium intake carries significant health risks [NIH ODS]. For the Grape Seed Extract and Collagen components, data is not available to make a specific recommendation.
