WHY COLLAGEN: Collagen is the largest and most abundant structural protein in the human body so it has a huge impact on overall body health. In particular, collagen forms and affects our skin, hair and nails. Research shows that our collagen levels begin to deplete from the age of 25 so that by the time we are 50, we will have lost around half of our natural collagen supply, causing signs and sensations of ageing.
AWARD WINNING LIQUID COLLAGEN: Each 10ml serving is packed with 8000mg of hydrolysed collagen - the most concentrated daily collagen supplement on the market. By using hydrolysed collagen peptides which are small enough to pass into the bloodstream, our liquid formula is also highly bioavailable, meaning that your body absorbs 90-95% of each dose for maximum results.
REAL RESULTS: Our loyal customers consistently feed back about the benefits of drinking collagen on their hair, skin, nails and overall well-being. Based on an AC Brand Discovery & Consumer self-assessment study, 93% of our customers noticed an improvement in their skin whilst 83% noticed their hair was thicker and/or shinier.
QUALITY INGREDIENTS: Our collagen supplements for women are made from 100% natural ingredients and don't include any artificial flavours, colours or added sugar. It's also free from gluten, soy, wheat, lactose, starch, yeast, alcohol, fat and cholesterol.
WHY CHOOSE ABSOLUTE COLLAGEN: Our award winning collagen drink is packed with premium marine collagen, protein and essential amino acids and is enriched with Vitamin C for optimum effectiveness. Join tens of thousands of customers who love us, and start feeling your absolute best today.
