★★★★★

We just completed a very large Homeopathic tablet order that required involvement from 4 different facilities. There was nobody else in the country that was willing to help us that we called until we found superior. First shipment came last week and we couldn’t be happier or more impressed with the team. Thank you Justine, Phil, Stephenie you are the best!

★★★★★
I was choosing between two companies to create a formulation, and it came down to their level of service, expertise and confidence in their ability to execute. After speaking to Phil, their lead guy who knows all things supplements and is very easy to communicate with, was enthusiastic and helped to create a strategy to see my vision through. The last thing you want is a transactional relationship in this industry, so whether you’re a first timer or a veteran, these guys know how to add value no matter what level you’re at. Highly recommend Superior and their team to get the job done.
★★★★★
When they say “Superior” they aren’t kidding. Of over 100 companies on our NSF list that we called, and over 20 that we talked to, Superior was the ONLY one that consistently answered their phones, worked incredibly diligently to problem solve and R&D an incredibly complex patented proprietary product, and consistently was two or three steps ahead of us, the landscape and their competitors. Looking forward to a long relationship Superior!
★★★★★
We’ve been using Superior for over 5 years. We came to them because our last manufacturer stopped making the capsule size I needed. I looked everywhere for a replacement. Luckily, I found Superior. They quoted me a fair price and sourced a hard to find ingredient quickly. In the 5 years we’ve had them make our product, which is a custom formulation, they have never delivered late once. Quality control is very high and I get constant updates from Phil our point person while it is being manufactured. I cannot recommend them enough.
★★★★★
Our previous manufacturer was 3 months late on a production and barely spoke with us. We have run many runs with Superior and as with all manufacturing, there was an order that was a little late because of poor crop growth. Not only did they warn us ahead of time they showed us the list of suppliers they were calling day and night to try to find replacement material. Best company ever!
★★★★★
Jake, Justine and Phil are just a few of the team members we have had the pleasure of working with at Superior. As a marketing agency working in the supplement industry, we work with many suppliers on behalf of our clients. I especially appreciate Superior Supplements Manufacturing because of their dedication to customer relationships. They go to extreme measures to ensure quality ingredients, fair pricing and great turn around times. The staff is also extremely knowledgeable. I would highly recommend this team.
