My mom is in her 50s and has been using Vital Proteins for over a year now. The powder easily dissolves into any liquid and is tasteless (she puts in her morning coffee). She originally purchased this product seeking help for her joints and stated within a month she started noticing results. Besides helping with her joints she feels that the product has also helped with her skin, hair, and nails. The downside she joked is her nails are growing faster now so she’s has to get a pedicure more often! She did state that during her use she tried switching to a cheaper product, only to notice the difference in results and quickly went back to using Vital Proteins.
