I buy RJ from Holland & Barrett, they do capsules. Groomers also produce a liquid supplement, I don't have the link to their site but you can get the details from the back of their EPO shampoo's in Pets At Home!
Forever Living also produce RJ capsules too. Mia had a very severe coat drop one year and I think the combination of Quistel washes & RJ helped to bring her coat back in quicker than before. I must admit I am very impressed by the Salmopet supplement I am giving the dogs too, both Mia & Curtis have lovely shiny (The shiniest Curtis's has ever been) coats.
You may be mistaking your neighbour for me!!!!! Sounds just like me! ;)
