It is tasteless so I’m more likely to use it often. I have noticed a difference with more strength and less pain when doing manual labor soi know it’s effective. With all the shoveling and carrying wood in all the time for the stone, I really needed this! Plus I trust this company for quality products and whenever I need something high quality, I choose them
