Every 25ml serving of Eternal Collagen contains 15,000mg of hydrolysed marine collagen. Absolute Collagen's 10ml sachet contains 8,000mg. Both numbers come straight from each product's own labelling, so the maths is simple: one shot of ours delivers almost twice the collagen of one of their sachets.
Absolute Collagen states on its own website that its formula uses Type I marine collagen. Eternal Collagen is hydrolysed marine collagen carrying both Type I and Type III, the two most abundant collagen types in the body, broken down into peptides in a ready to drink liquid.
No shaker, no scoop, no washing up. Keep the bottle in the fridge, pour 25ml, drink it. Chilled is when the naturally sweet tropical and citrus flavour is at its best. The whole thing takes seconds, which is why it becomes a habit instead of a cupboard ornament.
Absolute Collagen adds vitamin C to its formula. Eternal Collagen carries 19 added vitamins and minerals alongside the collagen in every serving, so one shot covers what would otherwise be a handful of separate supplements, shipped tracked from our UK warehouse.
Store the bottle in the fridge after opening. Cold is when the natural sweet tropical flavour comes through.
One 25ml serving a day. Use the measure and pour. No water, no shaker, no blender.
Take it any time of day. Consistency matters more than timing, and a 500ml bottle covers 20 days.
"With seven kids I've got no time for complicated routines. One little shot from the fridge in the morning and I'm done. It's the easiest thing I do all day."

Both are UK sold liquid marine collagens, but the labels read differently. Eternal Collagen delivers 15,000mg of hydrolysed marine collagen, Type I and Type III, plus 19 vitamins and minerals per 25ml serving. Absolute Collagen's sachet delivers 8,000mg with vitamin C added. On subscription, ours works out at £1.50 a day and around 10p per 1,000mg of collagen, against £2.00 a day and around 25p per 1,000mg for theirs.
One 25ml serving a day, any time that suits you. Most people take it in the morning. Consistency matters more than timing.
Naturally sweet and tropical with a citrus note. Keep the bottle refrigerated after opening. Chilled is when the flavour is at its best.
Each 500ml bottle holds 20 servings at 25ml a day, so one bottle covers 20 days and the three bottle subscription covers two months.
