My husband (65) and I (62) both take this Tri-Color Maca powder, it's been 1 month now and we noticed a difference in the first week or 2. Our focus is more sharper and the energy levels are incredible. We only take 1tsp each A day in the morning. We have been adding it to a drink we have been drinking since 2020. 1 Tblsp of high quality olive oil, 1 Tblsp of juice from a lemon and 1 Tblsp of local honey in 6-8ozs of warm water and the results have been rewarding. We are very blessed to have ran across this product..The company is right on making sure everything is OK and even sends updates, sales and article's to read by emails, very helpful and kind company. Don't ever change except to better yourselves. THANK YOU MACA TEAM.
