What's Inside Marine Collagen

200mg of hydrolysed Type I and III collagen peptides, plus 200% NRV biotin. The two ingredients your body actually uses to build skin, hair and nails.

Hydrolysed Type I and III Peptides

Marine Collagen

200mg · Bioavailable equivalent

Type I and III are the collagen types your skin, hair, nails, joints and blood vessels are actually made of. Hydrolysed means broken into peptides small enough for your gut to absorb. We use marine sourced collagen because it absorbs faster than bovine.

Biotin image

Vitamin B7

Biotin

100mcg · 200% NRV equivalent

Biotin is the B vitamin most associated with hair, skin and nails. Collagen gives your body the structural protein. Biotin gives it the cofactor it needs to actually build with it. The two work better paired than alone.

The collagen is sourced from sustainably caught fish. Pectin based, no gelatin. No synthetic dyes, no artificial sweeteners, no gluten, dairy, nuts, GMOs or fillers.

Directions

Each monthly bag contains 30 daily mini pouches. Each mini pouch contains six different gummies: one Mushroom, one Daily Greens+, one Marine Collagen, one ACV, one Sea Moss and one Metabolic. Take all six together once a day, with or after food.

Benefits

Marine Collagen supports the structural protein in your skin, hair, nails, joints and connective tissue. Paired with biotin (the B vitamin most associated with hair and skin), the gummy delivers both the protein building blocks and the cofactor your body needs to use them.

Why Take Marine Collagen?

Collagen is the most abundant protein in your body. It's what your skin, hair, nails, joints, tendons and blood vessels are made of. The catch is that you stop making as much of it once you hit your late 20s, and the drop accelerates from there. By 40 most people have lost around 10 to 15% of the collagen they had at 25.

You can't really eat collagen the way you eat protein. Whole collagen molecules are too big for your gut to absorb. That's why a marine collagen supplement uses hydrolysed collagen, broken into small peptides that pass into your bloodstream and circulate to where they're needed. The marine version (sourced from fish) absorbs faster than the bovine (cow sourced) version, and the peptide profile is closer to human collagen.

The other half of the story is biotin. Vitamin B7 is the cofactor your body uses to assemble keratin and collagen from raw protein. Without enough biotin, even abundant collagen intake doesn't build as efficiently. This is why collagen and biotin go together. The protein needs the cofactor.

Our marine collagen gummy gives you 200mg of Type I and III hydrolysed peptides plus 100mcg of biotin (200% NRV). One gummy a day, alongside the other five in your daily mini pouch.

30 Your collagen production drops from this age

Natural collagen production peaks in your 20s and begins declining by around 1% a year from your late 20s onwards. By 40, the drop is visible in skin elasticity, hair thickness and joint comfort.

200mg Hydrolysed peptides per serving

Hydrolysed collagen has been broken into small peptides your gut can actually absorb. Whole collagen molecules are too big to pass into the bloodstream. Hydrolysation is what makes a collagen supplement work.

I+III The collagen types in your skin, hair and nails

Of the 28 known collagen types, Types I and III make up around 90% of the collagen in your body. They're what your skin, hair, nails, tendons and blood vessels are built from. We use both.

200% NRV of biotin in every serving

Biotin (Vitamin B7) is the cofactor your body uses to actually build hair and skin from the protein you eat. We pair 100mcg of biotin in marine collagen with another 30mcg in Daily Greens+ for a 200% total.

Marine Collagen Questions, Answered

The things people actually ask us before they buy.

Can I buy Marine Collagen on its own?

Not as a standalone. Marine Collagen is one of six gummies in every GUUDIES daily mini pouch. The mini pouch covers your collagen, multivitamin, mushroom, ACV, sea moss and metabolic needs in one go, which works out cheaper than buying any of them separately.

Why marine collagen and not bovine?

Marine collagen peptides are smaller and more bioavailable than bovine, meaning your gut absorbs more of what you take. The amino acid profile is also closer to human collagen, particularly the glycine and proline ratios that show up in skin and joint tissue.

Is 200mg enough collagen to do anything?

Studies on hydrolysed collagen show benefits at doses from 2.5g to 10g, which makes 200mg in a gummy look small at first glance. But there's an important point. Daily Greens+ is part of a six gummy daily pouch, not a standalone collagen supplement. For people whose diets already include collagen sources (bone broth, fish, meat), 200mg of bioavailable peptides plus 200% biotin is a meaningful daily addition.

If you're targeting high dose collagen specifically, you'd want a powder alongside. Most customers find the gummy is the right level for general skin, hair and nail maintenance.

How long until I see results?

Skin and nail changes typically appear at 4 to 8 weeks of consistent daily use. Hair growth is slower, often 8 to 12 weeks, because hair grows from the follicle outward. Joint comfort improvements (if relevant) usually take 8 to 12 weeks. Consistency matters more than dose.

Is it suitable for pescatarians? Vegans?

Pescatarian yes (the collagen is from fish). Vegan no, this is the only non vegan gummy in the daily mini pouch. The other five (mushroom, Daily Greens+, ACV, sea moss, metabolic) are all vegan.

What kind of fish is the collagen from?

Sustainably caught wild fish, primarily white fish species. The collagen is extracted and hydrolysed from fish skin and scales, the parts that would otherwise be waste. No fishy taste in the finished gummy thanks to the natural fruit flavouring base.

Can I take this alongside a collagen powder?

Yes, no interaction concerns. If you're already taking a high dose collagen powder, the gummy adds biotin (which most powders don't include) and supplements your existing routine. If you stop the powder later, the gummy continues to support your baseline.
