Their product lineup looks legit -- lots of supplements, protein, vitamins, and performance stuff -- and it seems like they cater to both serious lifters and regular people just trying to stay healthy. The store also looks clean and well set up from photos, and reviews mention knowledgeable staff, which is always a good sign. I haven't made it in yet, but it's definitely on my list next time I'm in the market for supplements and want to support a local spot instead of ordering online. read more

The products here are all products I've seen over the years stand the test of time. Brands that try to reformulate or tweak based on science and feedback. The staff is always attentive at any location I visit and extremely knowledgeable. The price point is on par with purchasing from the brands direct. supplement Giant does a great job marketing by keeping us engaged but not using unrealistic fitness models regurgitating buzz words and pseudo-science. They have actual athletes and local legends to speak to their repertoire of rocket fuels. They don't try to stack cheap shirts and branded things and instead have a tasteful curated select few items allowing us to show our support, which shows me they have integrity and believe in their products. I am anaphylactic allergic to milk and unfortunately allergic to wheat. Those allergies make it difficult to navigate supplements, and I still find options there. At this location Jacob has been exceptionally welcoming and informative in regards to things he can procure if needed, as well as turning me on to products I wasn't aware existed. I do estate gardening/landscaping and am an endurance athlete so, it goes without saying eating can be a full time job, I need supplements to help buy me time between meals and for recovery. I'm so glad to live close to a Supplement Giant again. Thank you so much for your commitment to efficacy and integrity as a business. Thank you for hiring people who seem motivated to help. If I had one wish, it would be for a vegan protein that is strawberry flavored. But, please not pea protein. If you were Santa, I'd ask for a soy-based strawberry vegan protein or a blend. However, I understand supply and demand so, it is what it is. ‍ read more

By far the best supplement shop! Cheaper than Amazon and they really care about their customers!

This store is the bomb, always has what I need, always helpful. Check them out! Always great staff

I went in to supplement giant today to get a 5lb tub of protein. I asked if they price matched their local competitors and they said yes. I gave them a reciept showing the price I paid from their competitor just 10 minutes earlier. The guy spoke to the manager and he said they wouldn't price match because it was lower than their cost and that I should go to the competitor to buy more. If you're going to say you price match then you should honor your word. I ended up going to GNC and they were more than happy to do the price match for me which saved me a 20 minute trip across town. I will do all of my business at GNC and supplement world and I will tell everyone I know to do the same. read more

My husband and I stop by the stop supplement Giant and we bought a can of Isothority and it is a great product my husband loves it plus at the store they have excellent customer service very nice people always very helpful. I recommend anyone to stop by . read more

I love Supplement Giant. I've been going here for years and anyone who goes to GNC is a noob!!! I've done price comparisons, and I've found that the protein here is cheaper than what I've found on Amazon Prime or other competitor stores. They always give you free samples, the staff/owner knows what to recommend for your supplement stack if you're a competitor. I've been to a normal GNC store and I'm SOOOO shocked with what type of junk the employees try to sell me... it's like 'do you even lift bro?' Supplement Giant for LIFE! read more

Jessie was awesome! Cool guy with lots of knowledge. I usually hate supplement shops because they pressure you into the stuff they make the most profit on. Not here ! An awesome selection as well! read more

Supplement Giant - Vitamins & Supplements Near Me - Denver, Colorado

Supplement giant literally has all your fitness/health needs. All the staff are super knowledgeable of products and can help with any questions. Also right now during covid;customers that don't feel comfortable coming into store can pick up curb side. I would never shop anywhere else for my supplement needs. read more

The employees are really cool with assisting you in finding the right stuff for your fitness goals! They also always give out samples to try new pre workout or bcaa's, That's super helpful. BUT..... I have yet to find a protein that works for me. I've tried Nativ and isothority and I have issues with both! Mostly taste and consistency! Too sweet, too thick... makes it super difficult for me to get the protein down! I'll keep looking until I find the right one but not sure I will find it here. read more

Weird customer service felt very uncomfortable and awkward . I'm Sure the products are good ! Kinda gives you the feeling of talking down to you and very suspicious behavior . Recommend gnc up the road or Amazon .Hope it helps out and saves you time ! read more

Best supp store in Denver. They have everything great prices and best help. Wont go anywhere else

If you believe in the importance of local businesses to a community then you will see the value in this store. The prices are competitive or better than online outlets. The ability to discuss goals and expectations of products is crucial to any person who puts effort into their health and performance. The staff here is always helpful and will make recommendations or even steer you from a product if they do not think it will meet your expectations. I personally cannot afford to buy several products that do not work for me then have them sitting around or have to spend money finding something that works towards my intended goal. Personal discussion limits these wasted purchases. Like all business, this place is here to have a sustainable customer base. I have found that they make an effort to match you with a product that you will be happy with. That is really all I could ask from a supplement store. So I always come back for personal service and good selection at a fair market price. read more

Great business, great selection, no pressure, and the most knowledgeable staff there is in the supplement business.

My boyfriend and I have been buying all of our supplements at this location since it opened. We absolutely love Adam. He is very knowledgeable about all of the products and has even brought in a few items that we have requested. The store has everything you could possibly need and the level of customer service is top notch! The prices are extremely competitive and fair. We stop into the store once or twice a week and always look forward to seeing Adam. read more

Just moved to town and found this place thru yelp and proximity to my house. I was glad to hear that they don't sell/carry any proprietary products so there is no "push" towards any brand. I wasn't familiar with many they had but Colin was very helpful with his recommendations, friendly and gave me some samples to try at home. Then to my surprise weeks later received a hand written card in the mail checking in. I'll definitely be back. read more

I come here for all of my supplement needs. They have a friendly and knowledgeable staff willing to work with your lifestyle.

Supplement giant has every supplement you could possibly need. I am always blown away by how quickly they restock their product and they even notify me when my favorite creatine (Creagon) comes in. Stellar customer service! read more

This was our first time to visit this store. Drove from Pueblo co to check it out and I will say me and my wife are very happy that we did, very very knowledgeable staff and friendly from the time we walked in to the time we walked out we felt welcomed, had everything we needed plus more, also recommended other supps that I will be back for, upon checking out one of the workers gave us a few complimentary products that we didn't expect. All around great place to shop I will say from today on this will be my go to supp store and I will travel to get my supplements because of the great service and quality of store and customer service also unbeatable prices, I highly recommend this shop to anyone who has questions about product or just to buy if you already know what you need.. thanks guys for the great customer service. read more
