An overview of Glow25 collagen products: Which one is right for you?
Buying guide
Glow25 now offers six different collagen products – from the purist powder to a flavoured water blend. That's great for choice, but not always easy for decision-making. In this guide you'll find every collagen product compared side by side, plus an interactive Collagen Finder that suggests your best match in under a minute – based on your answers, not guesswork.
In short: no need to click through six separate product pages to figure out which collagen fits your routine, your taste and your goal.

How to choose the right collagen product
If you're wondering which collagen actually suits you, these six criteria matter more than any marketing claim:
- Collagen source & type: bovine collagen (type I & III) is the broadest base for skin, bone and connective tissue; fish collagen like in Collagen Intensive stands out for its especially small molecule size.
- Daily dose: look at how much collagen hydrolysate is actually in one serving, and how easily that amount fits your day – 15 g of powder vs. 2.5 g of sticks makes a noticeable difference in handling.
- Added nutrients: vitamin C, zinc and biotin carry EU-authorised health claims around collagen formation and the maintenance of skin and hair – worth it if you want more than plain collagen.
- Purity & lab testing: all Glow25 products are regularly checked by independent labs for heavy metals, hormones and microbiology.
- Format & everyday fit: powder for coffee/smoothie fans, sticks for your travel bag, capsules for anyone who'd rather not stir.
- Flavour: taste-neutral for maximum flexibility, or one of the flavoured variants if you want collagen to feel like a small ritual too.
Why Glow25?
With so many collagen products on the market, the real question is rarely "which collagen" – it's why this one specifically. Glow25 is Germany's best-selling collagen brand, built around a clear pro-ageing approach rather than classic anti-ageing thinking: ageing isn't hidden, it's supported consciously with the right nutrients. Founded in 2021 in Berlin, with the goal of taking collagen supplementation out of pure marketing and grounding it in real, traceable formulas.

Since 2026, the brand also has a new face: Sarah Jessica Parker has joined Glow25 as Chief Creative Officer, actively shaping brand strategy, campaigns and product development. The partnership launches with the "Nothing to Hide" campaign – a statement about not hiding the process of ageing, but living it visibly as part of your own story.

Collagen Finder: find your match in 60 seconds

Every product in detail
Here's an honest breakdown of what each of the six collagen products is actually made for, who it suits, and what's inside.
Collagen – Original with Vitamin C
The Original is the pure basic routine: 99.8% bovine collagen hydrolysate plus vitamin C, with no further additives. It's completely taste-neutral, which makes it our best-selling collagen product for anyone just starting out with collagen, or who prefers it pure, without extra vitamins or minerals. Vitamin C contributes to normal collagen formation for the normal function of skin.
Collagen Plus
Collagen Plus is built on the same bovine collagen base as the Original, enriched with zinc and biotin. Zinc contributes to the maintenance of normal skin, hair and nails, and biotin further supports skin and hair. Just like the Original, Collagen Plus is taste-neutral – ideal if you want the extra nutrients without any added flavour.
Plus Strawberry & Plus Lemon
Both flavours share the Collagen Plus formula (vitamin C, zinc, biotin) and are purpose-built for cold water – they dissolve without residue and turn your daily glass of water into a small ritual. Choose Strawberry for a fruity-sweet note, or Lemon for something brighter and more citrus-forward. If you're not sure which one, the Collagen Finder above will suggest the right pick.
Both flavours: €39.99 each · Strawberry · Lemon
Collagen Intensive
Collagen Intensive is our only product based on fish collagen (tilapia) and uses especially small tripeptides of just 500 Dalton – considerably smaller than the 2,000–4,000 Dalton of Original and Plus. The daily dose is only 2.5 g per stick, so each stick is precisely pre-measured instead of using a scoop. If you travel a lot, a single stick fits in any bag, no shaker needed. If you have a fish allergy, choose one of the bovine-collagen variants instead.
Collagen Capsules
Looking for the most low-effort routine possible? These capsules combine collagen type 1 with hyaluronic acid, vitamin C and pomegranate peel extract – just swallow five capsules a day with water, no stirring, no measuring. Hyaluronic acid is a natural moisture reservoir for the skin and complements the collagen inside. Great for travel, minimalists, or as an add-on to your collagen powder.
Frequently asked questions about Glow25 collagen products
For getting started, we usually recommend the Original: taste-neutral, no further additives, with vitamin C for normal collagen formation. If you'd like added zinc and biotin from day one, start with Collagen Plus instead.
Neither is objectively better – it depends on your routine. Powder mixes flexibly into drinks and lets you adjust the amount; capsules are pre-dosed and ideal for travel or anyone who'd rather not stir.
Yes, for example Collagen Intensive in the morning and a Plus powder in the afternoon. Just make sure the combined daily amount of zinc and vitamin C from multiple products stays within the recommended limit stated on the packaging.
All products except Collagen Intensive are based on bovine collagen. If you have a known fish allergy, Collagen Intensive (fish collagen from tilapia) is not a suitable choice – the finder above automatically excludes it if you flag this.
All collagen products are available directly in the official Glow25 shop, including a 60-day money-back guarantee and ongoing savings with the subscribe & save plan.

Our verdict
There's no single "best" collagen product – there's the product that fits your routine, your taste and your goal. Original and Plus are the reliable base, the two flavours turn collagen into a small daily ritual, Intensive is the compact option for life on the go, and the capsules are the fastest option with no stirring at all. Feel free to use the finder above if you're still unsure.
