I'm not very good at taking supplements, but this is now part of my daily routine. Tastes great, no powdery/grittyness, mixes really well and no horrible after taste! What's not to like.
I've seen a real difference in my performance and so has my PT.
After being on HRT for 3 years I decided to come off it last June as I didn't feel it was helping. A friend told me about creollagen in December and I've not look back.
Current deadlift PB 111kg not bad for a 54 year old!

Creollagen® Amalfi Lemon | Creatine & Collagen Powder

Tastes okay mixed well with water

Banging flavour, not tried anything else since

Love this product! I was previously taking collagen tablets daily and didn’t notice much difference as they were very low dose. Then I found this product which gives a high dosage of both collagen and creatine which is perfect. This products targets exactly what I’m looking for and I have noticed a difference in my skin and muscle recovery after using it for a month. The product tastes great which makes it easy to stick to. I am looking forward for my next one and watching the improvements!

Tastes great, dosages are unreal for the money compared to other brands I’ve used

Easy to shop and navigate, clear ingredients, info and advertising.

Onto my second bag of this already and I can’t recommend enough. No taste, goes well in my porridge or yoghurt. Never seen a collagen product with that much collagen in it!

Creollagen® Unflavoured | Creatine & Marine Collagen Powder

Tremendous flavour setting the new benchmark in the market. Lifted my baseline power and gives me the assurance of overall muscle integrity. Tastes phenomenal and organic, great with a meal!
