My husband has a small bottle of Miralax that he usually refills from a double pack of Sam's brand lately. He puts it near the coffee maker with a jar of collagen powder, which also helps the go as well as adding protein. He has a scoop of each in his coffee every morning. No taste, no smell, no problem. It was easy for him to make it a habit that way, too.

Our favorite collagen was the Trim Healthy Mama brand from their store, but during COVID, they were out a lot, so we started buying Native Path. They almost doubled their price, so we ended up with the blue Vital Proteins from Walmart. There are a lot out there, but I found that some of them did have a smell, and that bothered me, so I am happy with the price and lack of smell with Vital Protein. It helps the nails, hair, and skin, too.
