The Herds We Stand Behind

Everything we make starts with grass-fed British tallow - and every month we're out on British farms, filming the breeds and the people feeding the nation. Different farms, different herds, same mission. Buy a jar, fund the coverage.

Blagdon Estate

Blagdon Estate

White Park Cattle • Northumberland

Home to one of Britain's oldest cattle breeds, they bring fresh milk straight to the local community through their mobile milk van. We filmed their Open Farm Day and captured how they're diversifying beyond the farm.

Hadrian's Meat Co

Hadrian's Meat Co

Belted Galloways • Northumberland

Tommy farms Belties, butchers his own beef and sells it direct. We spent a day on the block with him - he does beef boxes too. Give him a follow.

Tranwell FarmPrize-winning

Tranwell Farm

Coloured Ryelands • Northumberland

A proper family farm. Philip and Sarah's sit-down interview is the most-watched film we've made - every farm has a story, and theirs is a belter.

Britain's Fittest Farmer

Proud Sponsor

We back the competition that celebrates the people who feed the country.

Made by hand in Morpeth

Rendered slow. Whipped in small batches. Poured, labelled and boxed by hand — by us, in Northumberland. Not a white-label factory with our sticker on it.

If a batch isn't right, it doesn't ship. That's the quality-control department: us, refusing to send you anything we wouldn't put on our own kids.

Questions? Answered.

Everything from ingredients to subscriptions is answered here, so you can feel confident.

Simply mix 1 scoop (approx. 10g) daily into warm or cold beverages such as coffee, tea, smoothies, or water. Because it is completely unflavored and easily dissolvable, it won't change the taste or texture of your favorite drinks. You can also add it to overnight oats and other recipes.

Store your collagen in a cool, dry place, away from direct sunlight. For optimal freshness, make sure the bag is sealed. No refrigeration is required.

Most people begin noticing benefits - such as improved skin hydration, stronger nails, and joint comfort - within 4 to 8 weeks of consistent daily use. For optimal skin elasticity and hair strength, long-term daily use is recommended.

Yes! Our collagen peptides are heat-stable, meaning you can mix them into hot soups, oatmeals, or baked goods like protein pancakes and muffins without losing any nutritional value.

Absolutely. Daily supplementation helps replenish the body's natural collagen stores, which naturally decline as we age. It is a pure, single-ingredient formula designed for everyday wellness.

Meet the founder, Ryan.

I started Fat Cow because my own skin was a state and the ingredient lists were a joke. It's made in Morpeth, from British farms we back publicly - because if farming goes, this product can't exist. Try it for 30 days. If your skin doesn't rate it, I'll refund you myself.

Love the product and your fallow skincare is 10/10 just home from holidays and it's been a lifesaver

Customer video review of Grass-Fed Collagen Peptides

Loving this product so far! It’s high quality and totally tasteless so mixed well with my multivitamin drink and other supplements. I’ve only been taking it for a few weeks but already noticing stronger hair and nails!

Grass-Fed Collagen Peptides

Customer photo review of Grass-Fed Collagen Peptides

I have very eczema prone skin. Since using fat cow I think parts of my skin are more moisturised but I haven’t been able to stop using my steroids yet. It feels gentle on my skin and the moisturising feel lasts but it’s not all better yet.

As first time users of collagen this seems to be working wonders on my skin.

Grass-Fed Collagen Peptides

Customer video review of Grass-Fed Collagen Peptides

Too early to comment on the effects (hoping to make my hair grow faster and longer) but it really is tasteless and so quick and easy to mix up.

Grass-Fed Collagen Peptides

Customer photo review of Grass-Fed Collagen Peptides

Been taking the collagen for about 6 weeks and it has done wonders for my nails! They were very weak / brittle but now they are actually growing evenly and much stronger! I think I have noticed a reduction in my joint pain too so definitely seems to be going in the right direction. I wasn’t keen on the flavour in tea / coffee but mixed in with a ginger or elderflower cordial it is lovely. I use a shaker and there’s no lumps at all.

I’m using this collagen peptides in my morning bulletproof coffee. It dissolves easily using a hand whisk it adds a nice creaminess to the coffee , with no bad aftertaste in fact, it’s quite complementary to the bulletproof coffee so a great addition to my morning ritual.

Customer photo review of Grass-Fed Collagen Peptides

I’ve been using collagen for about a month now & I can already see a difference in my nails & hair. I love it I always have it in my morning coffee can’t even tell it’s in there.

Customer photo review of Grass-Fed Collagen Peptides

I recently began incorporating collagen peptides into my daily routine, and although it’s early days, I’m already eager to share my initial impressions. Each morning, I either mix it with my oatmeal or stir it into my tea. While the collagen has a slight taste, it's not overpowering and blends well with both. I purchased this product primarily because I am interested by its potential health benefits. Collagen is known for its properties that aid in rebuilding and restoring joints and muscles, and it promises to promote glowing, youthful skin. Given these benefits, I'm hopeful to experience positive changes over time. In addition to the collagen, I've also started using Fat Cow Skincare's tallow soap. This combination means I am nurturing my body both internally, with the collagen, and externally, with the nourishing soap. I’m optimistic about seeing improvements in my skin and overall well-being in the coming weeks. Regarding the packaging, I find the design of the packet quite appealing; it’s visually pleasing and informative. However, I do encounter some challenges when closing the seal, as it can be a bit tricky at times. Overall, while I am only at the beginning of my journey with this collagen peptides, I am pleased with my decision to try it and am looking forward to observing the benefits it may bring.

Grass-Fed Collagen Peptides

Been taking for over 30 days now, and I have noticed a difference in my skin, and my hair. As someone who was loosing their hair it’s definitely has helped. I know more benefits will keep coming as I continue to use it. It’s a great product and love adding it my protein shake or morning coffee.

Grass-Fed Collagen Peptides

On my second pouch and can honestly say I’m really happy!! From someone who has tried numerous collagen powders some of which were very expensive. My nails are stronger and hair feels lovely. Also had no side effects in relation to gut so I will definitely keep my subscription. Would highly recommend!!

Grass-Fed Collagen Peptides

Delighted! Tasteless, blends easily and does the job. I'm a repeat customer 😁

Grass-Fed Collagen Peptides

I love all your products. My skin is better , my hair better. Can’t praise it highly enough. I’d give it 10 stars if I could.

Grass-Fed Collagen Peptides

Great product, this is my second time ordering and I’m very happy!

Grass-Fed Collagen Peptides

Easily dissolves in tea and coffee. Barely notice the taste. Have only been taking it for a week, so not seeing any obvious benefits yet.

Grass-Fed Collagen Peptides

I have had a couple of collagen powders over the last few years. But this feels clean and mixes well with drinks, and I have noticed a less crinkly neckline since using this! Only drawback I can think of is when you get to using the last 1/2 of the bag and your hand goes into the bag it is covered in powder!! Would be nice to maybe have a plastic container option to use for continued use, to prevent this happening. Would be much cleaner and more user friendly too.

Grass-Fed Collagen Peptides

Grass-Fed Collagen Peptides

Great product, really easy to add into your daily life to enhance your wellbeing. Looking forward to seeing the longer term effects.

Grass-Fed Collagen Peptides

Really easy to take just stirred into milk or tea Take it every morning really helps the stomach get ready for the day

Grass-Fed Collagen Peptides

I use this in my morning coffee, it dissolves easily and gives no ‘taste’ to the coffee. I’m hoping it’s helping as I have arthritis and am osteopenic so need all the help I can get!

Grass-Fed Collagen Peptides

I have not took any photos as I have only been using it for 2 weeks. but everyone has noticed the difference in the appearance of my wrinkles and skin. They are already looking at buying it for themselves.

Grass-Fed Collagen Peptides
