Great company and wonderful products!

Have been ordering and using some of Ossa’s products for a while now….. always excellent. There was a slight mix up with my latest order and one item was incorrect….. however these things happen and they couldn’t have been more helpful or quick in sorting it out. Really first class customer service.

J Reynolds

Promp and efficient service.

Katz Cowley

My (somewhat spoilt!) dog and I absolutely love the bone broth and I love that it thickens into a jelly once opened and placed in the fridge, showing how much goodness is in there!
I make broth smoothies and they get super frothy with the collagen in the broth!
(I add salt, lemon, cayenne, turmeric, ginger & honey, tastes DIVINE, and great for the gut!!).
I'm going to try their ghee now, after seeing the reviews! :)

Love Ossa Organic. I've been buying from them for about half a year now. I love the quality of the products especially the collagen peptides and bone broth. I would highly recommend. In fact I gave my mother who is in her 70's a bag of the collagen peptides and she has noticed she has been growing more hair!

Serra Kuman

Excellent taste, fast shipping, great customer service.

Teresa Brown

Excellent products and helpful and caring team.

I love Ossa organic products, good customer service and fast delivery.
Their Collagen powder is a must have- its great as it doesnt taste of anything, i mix it with my coffee every morning, can even mix it towards your foods ie pancakes batter, shakes or soups.
Also in love with their Ghee, it tastes amazing my kids loved it so much. I use it to make egg fried rice for them and alternative to sauté when i make my stews.
their customer service is amazing, they got back to my queries efficiently.

Peter Reed

Usual 5 star service & product

Amazing to buy from

Naomi Shaw

I’m delighted to have found Ossa Organic products as I’ve been looking for healthy alternatives to items such as collagen, ghee and tallow. I also love the bone broth as it saves a lot of time (we had been making our own). Having it readily available in the freezer means it’s easy to add to any meal at a moments notice.

I cannot rave enough about Ossa's products! Absolutely hands down the best bone broths, tallow, ghee, collagen and gelatine around.

Everything is clean, organic, grass fed, the company's ethos is brilliant. Totally worth investing in your health and your family's health by buying from Ossa. I don't have a huge income but when I can, I always make sure I buy what I can from Ossa because in my opinion they are the best. They have a sister skincare brand Fierce Nature which is full of epic clean and natural treats for your skin and hair. If you haven't checked it out yet you should!
