Backed by science. Seen in the mirror

Collagen peptides are one of the most studied nutrients for skin. In a placebo-controlled trial, women drinking collagen daily saw wrinkle depth fall by 26.8%, more than four times the placebo group. In another, a marine collagen drink lifted the healthy-hair score by 31.9%.
Core™ gives you 11,000 mg of hydrolysed marine collagen in every serving, with vitamin C, biotin and hyaluronic acid working alongside it.

One formula, done properly. Made to be kept up
We kept seeing the same thing. Women buying a collagen powder for their skin, a second jar for hair, something for energy, something else for the thyroid, and giving up on all of it within weeks. Not because they did not care, but because no routine survives five jars.
So we made one. Core™ puts marine collagen and the nutrients women actually look for into a single daily serum, and nothing they do not need: no sugar, no fat, no capsules to swallow.
You take it every day, so we hold it to a higher standard. Core™ is made and packed in Sweden, it is lab tested, and its collagen peptides were studied on 106 women before we put our name on it.

Why is Core™ lab tested?
Most people assume a supplement is checked before it reaches the shelf. It isn’t. In the EU, food supplements don’t need approval before they’re sold, so testing is left to each brand, and many simply skip it. Independent tests of collagen and protein products have repeatedly found heavy metals in products already on sale.
Marine collagen carries a particular risk. Fish can carry heavy metals such as mercury and lead, and a liquid supplement has to stay free from bacteria.
So we test for both. Core™ is lab-tested for heavy metals and bacteria, and pH-stabilised for purity, so it stays clean and fresh in the pack. The collagen in Core™ has been clinically studied, and Core™ is made in Sweden to GMP, HACCP and ISO 22000 food safety standards.
In short: what’s on the label is in the pack, and nothing that shouldn’t be.
Why is there more than collagen in it?
Because collagen alone does not cover what women need. Vitamin C is what your body uses to form its own collagen. Biotin and selenium are there for hair and nails, the B vitamins for energy, selenium for the thyroid, B6 for hormonal activity and vitamin D for bones and muscles. One drink covers the whole list, so you are not juggling five jars.
30-day money-back guarantee
Yes. Every order comes with a 30-day money-back guarantee. Full details are in our Returns & refunds policy.
Where is Core™ made?
In Sweden, to EU food supplement standards.
Why marine collagen, and why hydrolysed?
Marine collagen is rich in types 1 and 3, the collagen your skin is built from. Hydrolysing breaks it into small peptides that dissolve fully in the drink and are easy for your body to absorb, which is why Core™ is a smooth liquid, not a gritty powder.
Does it help if I am noticing more hair shedding?
Biotin and selenium are in Core™ for hair, and in the eight-week study of Core’s collagen peptides 86% of women reported healthier hair. In a separate 12-week trial, a marine collagen drink lifted the healthy-hair score by 31.9%.
How does Core™ support hormones and the thyroid?
Vitamin B6 contributes to the regulation of hormonal activity. Selenium supports normal thyroid function. Two separate jobs, both in the same daily drink, alongside the B vitamins that keep your energy steady.
