Meet Louise Arnold
Some of the most inspiring Kollo community stories are from people who started something completely new in their late 30s and early 40s and just kept going. Today we'd like to introduce you to Louise Arnold — personal trainer, mother, first-time marathon runner at 41, and one of our UK ambassadors.
Hi there, I'm Louise. A personal trainer, mother, crafter, nature lover, runner and goal chaser.
Initially, I was drawn to Kollo as I am a dedicated runner and have recently completed my first marathon at the age of 41. I only started running as I approached 38 — please never think you're too old to start something new! As an active woman navigating my 40s, I wanted to invest in daily habits that support my long-term training and general wellness.
The first thing I noticed after taking Kollo for about 4 weeks was how nice and strong my nails had become. Just before I turned 40 — which is when I first started taking Kollo — I also started growing out my hair from all the old hair dye and highlights. My natural grey hair is now so soft, I've never had soft hair before.
I often get compliments on how nice and smooth my complexion is, which is rather nice too.
I love the fact that Kollo has added B vitamins (B1, B5, B6, B12) which contribute to normal energy-yielding metabolism, vitamin C which contributes to the normal function of the immune system, and l-lysine — an essential amino acid the body uses in various protein synthesis processes. Kollo has a lovely tropical punch flavour, so absolutely delicious.
I am looking to compete in my first triathlon in the summer and I appreciate having Kollo as part of my daily routine through the months of training ahead.

Why we love working with Louise
Louise represents something we care about deeply at Kollo — the idea that new chapters aren't age-restricted. Starting running at 38, completing her first marathon at 41, and now training for her first triathlon isn't just admirable; it's genuinely useful proof for anyone reading this who's told themselves it's too late. As Louise says: please never think you're too old to start something new.
What we especially love is her openness about growing out her natural grey hair. Softness returning to hair that's spent years being coloured is often one of the most noticeable early changes people report on marine collagen — and Louise talking about it honestly matters, because it's a change many of our community will recognise from their own experience.
