I have had several capsules broken in the container. This causes a messy yellow powder to spread throughout the container.

Hi William, thanks for bringing this to our attention. We pride ourselves on our high standards so this is disappointing to hear, and we’ll be looking into this. If it’s ok with you, we’ll be in touch to get a few more details from you and rectify the situation. In the meantime, as long as the seal was still in tact on the bottle, the capsules that aren’t affected are still perfectly safe to consume. Of course, that said, this isn’t an acceptable situation and we apologize this product hasn’t reached you in the condition we would like it to. We’ll be in touch to sort it. Thanks for giving us the heads up on this!

Doris! It's so good to hear from you. We're really pleased you're feeling the benefits of Flex. As well as protecting against stiffness and joint aches, Flex can also protect against free radicals, strengthen bones and improve shock absorption and resilience. In essence: all that good stuff that goes on behind the scenes! This routine maintenance will keep a spring in our step Doris! We hope you are well, and thanks for taking time to leave us a review. It's great to have you with us.
Performance labs have very good service, also to deal with, FLEX is a good product that helps me a bit, l know it not meant to work miracles, as l have fairly severe osteoarthritis in both knees , both hips and lower back, it helps keep me moving.

Colin, thanks so much for sharing your experience with us. We're so sorry to hear you're dealing with OA. Staying as active as you can is obviously really important to managing your condition, so to hear that Flex is helping you move is music to our ears. The Boswellia in Flex offers anti inflammatory effects. We chose that because clinical trials showed it offered anti-inflammatory and anti-arthritis effects, and may improve pain and physical function for anyone with joint disorders. We really hope you're feeling that Colin. Thanks so much for taking time to share your experience. It's great to have you with us.
Excellent product. I have back issues and Flex has given me more movement and enabled me to enjoy many activities such as going for walks. climbing stairs etc.

Hey Carryn, thanks for sharing your experience of Flex, this is so good to hear. We're pleased Flex is giving you that all-round joint support you're looking for. It's amazing how good getting outside and going for a walk can make you feel, so anything that helps with that, has to be a good thing! Thanks for taking time out to leave this review, and thanks for your custom Carryn, we can see you've been with us a while, we appreciate that!
I love Performance Lab's Flex! I have been using it for about 4 years now. I am 72 and it really helps my joints and somehow improves my mood as well. I started taking this after reviews showed it is a better product than Relief Factor.

Carol! Thanks so much for getting in touch, it's always great to hear from our long-term customers. This is music to our ears. Flex is an all-round approach to joint health, so the benefits can be far reaching and varied depending on the individual. Not only is it designed to soothe stiffness and joint aches, it can also protect against free radicals, strengthen bones and improve shock absorption and resilience. As for the improvement in mood Carol, it could be all of those endorphins you're getting from being so active! Whatever it is, keep going! Thanks so much for taking time to write us this review, we really appreciate it.
This is one of the most effective supplements that works best for me and is the most cost effective that I have found. Customer service and support has been great!

Hi there, we're so pleased to hear that! Thank you so much for taking the time to leave this positive review, we're glad you're feeling the benefits of Flex.
I have used Flex for several years now and I love it. I feel it helps my joints stay flexible. I workout with a trainer every week and she says I do the deepest squats she's ever seen. I am 72 years old and going strong! Thank you, Flex!
