I am so thankful to have found out about Lifesource vitamins. I questioned the quality of big brand vitamins found on store shelves after researching and learning that a lot of ingredients are sourced from all over, even overseas. I wanted to feel confident that the vitamins I take are true quality and US sourced. I am confident when taking Lifesource vitamins knowing that care and accountability are a core value in the making of their products. I have been extremely satisfied with all the products I have tried so far and highly recommend their products. Thank you, Lifrsource!
