Why People Switch

Four reasons Eternal Collagen wins

1

Nearly double the collagen per serving

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.

2

Two collagen types, not one

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.

3

A routine you will actually keep

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.

4

19 vitamins and minerals, not just one

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.

The Ritual

Three steps, done by breakfast

Step 1

Keep it chilled

Store the bottle in the fridge after opening. Cold is when the natural sweet tropical flavour comes through.

Step 2

Pour 25ml

One 25ml serving a day. Use the measure and pour. No water, no shaker, no blender.

Step 3

Drink and go

Take it any time of day. Consistency matters more than timing, and a 500ml bottle covers 20 days.

Brand Ambassador

"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."

Questions

Before you switch

How is Eternal Collagen different from Absolute Collagen?

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.

How much do I take, and when?

One 25ml serving a day, any time that suits you. Most people take it in the morning. Consistency matters more than timing.

What does it taste like?

Naturally sweet and tropical with a citrus note. Keep the bottle refrigerated after opening. Chilled is when the flavour is at its best.

How long does one bottle last?

Each 500ml bottle holds 20 servings at 25ml a day, so one bottle covers 20 days and the three bottle subscription covers two months.

Can I cancel my subscription?

Yes. Pause, skip or cancel anytime from your account. No notice period and no phone calls.

When will my order arrive?

Orders are dispatched from our UK warehouse on Royal Mail Tracked 48 or DPD Local, and you will get tracking by email.

What is the returns policy?

Unopened bottles with the security seal intact can be returned within 14 days of delivery. Return postage is paid by the customer and refunds are processed within 5 to 10 working days of inspection. Full policy at eternalcollagen.co.uk/pages/returns-policy.
