Supplement Giant is a great store with a huge and wide selection of high-quality supplements, protein snacks, vitamins, and ready-to-drink or eat items. The staff is super knowledgeable, friendly, experienced, and always helpful, providing excellent and honest customer service without pushing products. The folks there are amazing and offer great service and great prices. For the best no-BS experience in the Denver area, these are the guys.
Wanted to change my daily vitamins. The mgr was super friendly and knowledgeable. Not a salesman type but like you were talking to an informed friend. So far I think he nailed it and I’m enjoying my new vitamins. I would definitely recommend and will be a returning customer.
