This has become our go-to supplement shop. Every time we stop in, we're greeted with a smile and treated like customers, not just another sale. What stands out most is the staff. They're friendly, approachable, and actually take the time to answer questions. If they don't know something, they don't make up an answer they'll check with someone who does or look it up to make sure you're getting the right information. That kind of honesty goes a long way. The prices are fair, especially considering the quality of the products they carry. We've never felt pressured to buy something we didn't need, which is refreshing. If you're looking for a supplement store with knowledgeable people, reasonable prices, and great customer service, this is definitely a place worth checking out. read more

NSS Nutritional Sport Supplements - Vitamins & Supplements Near Me - La Habra, California

Sub-satisfactory customer service. Lack of initial greeting and not assisting in the product that needed to be purchased.

Been coming here for years. The owners are always super helpful. My BF and I get our protein, creatine, fat burner and workout products from here. They legit have everything and always well stocked. Anytime I have a question on something, they always guide me in the right direction and provide good feedback. They're super knowledgeable about the products they sell. read more

Great place. Bought some of the older Jack3d here a long time ago. Bit overpriced but eh. A chill small shop that has lots of great supplements. Price wise, it's okay. You can find some cheaper online, but in retail, it's a good deal. If you need supps quick check this place out! Support your local! read more

Great place to get everything you need. No nonsense and even carry things you can usually only get on the Internet at better prices. Super nice folks!! read more

That's Right 1st Reviewer! This place is my favorite supplement place! They pretty much carry everything you need "supplement" wise. This place is 10x time cheaper then wack ass GNC and max muscle, but max muscle is better then GNC. They also price match, but theres no need because there always the cheapest. Everytime I need protein this is where I go! If your looking for a certain supplement call them and ask them, they will get it for you! I highly recommend this spot for anyone! Please note supplements dont work unless you exercise and diet correctly LOL - Peace read more

Lived nearby for a few years now and never really noticed this place! I always would get my supplements (whey, pre , bcaas, shakers) from other places. Found this place and met Maricio. Awesome service and had everything I was looking for at a great price. I called gnc and this place was cheaper! It's my new supplement spot now. Thanks again! read more

I've been here a few times and the nice lady always takes care of my husband and i. I recently returned a meal replacement tub that I purchased and luckily she had given me a sample to try cause when I tried it, I didn't care for it. This saved me from opening the sealed tub and rendering the product unreturnable. She gladly took the unopened tub back and traded me for a different product. She even recommended some good protein bars and energy drink. I love when places have helpful people who know the product they're selling. Thank you, girl! I shall be back for my coconut almond ONE bars! read more

Every time I come here, I get the BEST service from Araceli! They have the greatest prices or match what I've seen advertised. I don't even live near here, but when I'm in the area, I definitely make a special stop here to stock up! Araceli & other employees are educated on products I've asked about, are fully stocked with most proteins, pre workouts, amino acids, quest bars, fat burners, & my general health needs. read more

Absolutely the worst here. I came a few weeks ago to buy a meal prep bag. Some where in a bag and some were not. They opened the bag up so I can see inside and then ALL I did was put it in my trunk and on the floor in my room and that's it! I called and said if I could return it and they said yes, but when I came in she said it looked OLD, DUSTY AND DIRTY and used?! Like seriously?! All you had to do was wipe it down and it was clean again. She said she wouldnt take it back. Absolutely RIDICULOUS, they scammed me good. DO NOT COME HERE. Very upset EX customer read more

AMAZING nutritional supplement store. I get all of my essentials here : pre-workout, BCAA's, protein shake powder, and more! Love this place, love the employee's attitude. They are also slightly cheaper than GNC- if that matters to you! I would still come here just for the great service and to lend business to a small but great business such as this! read more

Great place to purchase all your supplement needs, I really like the One protein bar and the fact that they have a variety of everything is great! I've purchased the One bars on Amazon before but they just weren't up to par, maybe they were just a bad batch or just old. The staff and owners are WONDERFUL, professional, knowledgeable and very friendly. I also like supporting small businesses. I know I appreciate my small business having support. read more
