I buy clean B12 and clean collagen from British supplements and also take iron supplements (purchased elsewhere). I can honestly say I feel much healthier after taking them as I was suffering from fatigue and brain fog. The communication received from the company is good and reassuring especially as a new customer. They were delivered in good time and packaged well. I have ordered from them twice now increasing my order the second time and will continue to use them as I believe it is a quality product. I recommend this company.
