Best nutrition shop I’ve ever been to hands down. Brian takes the time to listen to your goals, designs a meal plan for you and recommends the right supplements to achieve your goals with out trying to up sell you on products you just don’t need. If you are just starting out, or hit a plateau in your workout, or are a season vet, go see Brian. You won’t regret it.

By far the best nutrition shop. Every time I go in Brian is always in and helps out. Went in today to grab some bcaas and he threw me a free shirt and a new shaker bottle. Definitely would recommend this shop to everyone. I definitely will be back.

Normally, I don't like going into these types of stores, but Big Daddy's Nutrition is different. I don't feel intimidated or embarrassed and Brian is very nice, knowledgeable and extremely helpful. I highly recommend the bars. The Almond one is very yummy and tastes almost like an Almond Joy! So many flavors to choose from. Thank you Big Daddy's and see you soon!!!

This is Faith, I was in your store on Saturday morning with my friend Rufus. I'd like to start with saying, "Thank you sooo very much" for all of your help, guidance, advice and for the GREAT deals that you gave me. We will definitely be back to see you. You made us feel at home in your store and you have given me added motivation to get healthy and to continue eating right...
