Planet Paleo Collagen Review UK 2026: Tested and Rated by a Nutritionist

Short answer: Planet Paleo Pure Collagen earns 4.2/5 - a well-dosed, clean-label bovine collagen with competitive cost-per-10g against Ancient + Brave.

Planet Paleo sits at the premium end of the UK collagen supplements market. Its grass-fed, paleo-positioned packaging signals clean sourcing - but premium collagen is not automatically well-dosed collagen, and this Planet Paleo collagen review sets out to do the one check the brand and most retailers skip: what do you actually get per serving, and does the price hold up when you run it against the alternatives?

I reviewed the Pure Collagen, Marine Collagen, and Multi Collagen powders, checking each against the studied dosing range of 2.5-15g per day referenced in hydrolysed collagen research. The dose numbers are good. The sourcing claims stand up. Whether the price is justified depends on which product you choose - and the gap between the 225g and 450g options is wider than most buyers realise.

Planet Paleo Pure Collagen delivers 7.5g of hydrolysed bovine collagen per serving from a single-ingredient formula. That dose sits inside the 2.5-15g range studied in collagen research, the sourcing is traceable, and the clean label is genuine - no fillers, no flavourings. The Marine Collagen matches the dose and carries MSC certification for sustainable fishing.

Where Planet Paleo earns its price premium is quality assurance: lab testing for pesticides, heavy metals, and hormones, grass-fed certification on the bovine range, and MSC certification on the marine range. Where it loses ground is cost-per-10g collagen compared to positioned rivals like Ancient + Brave at matched daily doses.

Rating: 4.2/5

Who it is for: UK buyers who prioritise traceable sourcing, clean labels, and a dose that sits inside the studied range, and are comfortable paying a small premium for verified quality assurance.

Price per serving (Pure Collagen, one-off purchase): 77p per serving (225g at £22.99, 30 servings)

Cost per 10g collagen (Pure Collagen): approximately £1.02 at one 7.5g serving per day

Planet Paleo is a UK wellness brand founded on naturopathic principles. The range centres on collagen powders and bone broth products, with a positioning built around grass-fed sourcing, minimal ingredients, and what the brand describes as ancestral nutrition.

The core collagen range includes four products: Pure Collagen (bovine, single-ingredient), Marine Collagen (wild-caught, MSC-certified), Multi Collagen (five collagen types from bovine, fish cartilage, and eggshell membrane), and a Cacao Collagen blend. The brand also produces functional bone broth powders and collagen latte blends under the Collagen Hottie label.

Planet Paleo products are available direct at planetpaleo.co and through UK retailers including Holland and Barrett, Bodykind, Planet Organic, and Amazon UK.

The 'clean' and 'paleo' positioning is not purely marketing. The single-ingredient Pure Collagen contains nothing beyond grass-fed bovine collagen hydrolysate. The Multi Collagen adds vitamin C and bamboo extract (75% silica) alongside its three collagen sources - a short, readable formula by supplement standards.

My approach to any collagen supplement review involves four checks: verifying the stated collagen source against certification standards, confirming the dose per serving against the 2.5-15g range referenced in hydrolysed collagen research, reviewing the full ingredient label for unnecessary additives, and assessing taste and mixability across different preparation methods.

For Planet Paleo, I tested the Pure Collagen and Marine Collagen powders across a two-week period, mixed into cold water, warm water, and coffee. I also reviewed the Multi Collagen formulation and calculated cost-per-10g collagen across the range and against named UK competitors.

Friction Moment #1 - the dosing claim: Planet Paleo's recommended serving is 7.5g of collagen, taken once daily. That falls inside the studied range. However, the brand states "1-3 servings daily" on the Pure Collagen packaging. Three servings per day delivers 22.5g - above the upper end of commonly studied doses. The evidence base at doses above 15g is thinner than the evidence supporting the 2.5-10g range. One to two servings daily is the range best supported by current research; three servings is a product positioning choice rather than a clinically driven recommendation.

The single-ingredient formula is the clearest strength of the Pure Collagen. There is no proprietary blend obscuring the collagen content, no fillers, and no flavouring agents. You can calculate exactly how much collagen you are getting per serving because it is the only ingredient.

The MSC certification on the Marine Collagen is meaningful. It verifies sustainable fishing practices and chain-of-custody tracking from ocean to product. Buyers choosing marine collagen for ethical reasons have independent verification here rather than a brand claim alone.

The Multi Collagen is the most nutritionally complex product in the range. Type II collagen from fish cartilage is the collagen type associated with cartilage and joint support in the research literature. The addition of vitamin C is clinically sensible - the body requires vitamin C for endogenous collagen synthesis, and combining supplemental collagen with vitamin C is standard in well-designed formulations. The bamboo silica addition is a weaker inclusion by evidence standards; silica research for joint or skin support is at an earlier stage than the core collagen evidence.

Friction Moment #2 - the EFSA and NHS position: No health claim for collagen supplements relating to skin elasticity, joint function, or wrinkle reduction has been approved under UK or EU regulations as of 2026. The European Food Safety Authority assessed collagen hydrolysate in 2012 (EFSA Journal 2012;10(5):2702) and did not authorise the submitted health claims. Planet Paleo, in line with compliant UK supplement brands, makes no specific health claims on its product pages.

Buyers should understand that the evidence base for collagen supplementation is growing. Several randomised controlled trials have demonstrated improvements in skin hydration and joint comfort at doses of 2.5-10g per day - including work published in the Journal of Cosmetic Dermatology (Asserin et al., 2015) showing significant improvements in skin hydration and dermal collagen density within eight to 12 weeks. But this evidence has not yet met the threshold for an authorised health claim in the UK. The science is promising and worth understanding; it is not yet regulatory-grade.

After two weeks of testing across cold water, warm water, and coffee, one thing stands out: the Pure Collagen is genuinely neutral. In cold water it dissolves cleanly within 20-30 seconds of stirring, with no clumping and no residue at the bottom of the glass. The resulting drink has a very faint protein note but nothing that registers to most palates - it reads as water with marginally more viscosity.

In hot coffee the dissolution is faster and even cleaner. There is a perceptible increase in body - the drink coats the tongue with a smoothness closer to a milk-white coffee than a black one, but without any flavour impact. For readers who stir collagen into their morning coffee - and if you are looking to pair that with quality beans, our guide to the best coffee beans in the UK is worth reading - the Pure Collagen performs well.

The Marine Collagen behaves identically in terms of texture and dissolution. Some marine collagen products carry a faint fish note at the back of the taste. In the Planet Paleo Marine Collagen I detected no fish flavour at any preparation temperature. For lower-quality marine collagen sources this is a more common issue; its absence here is a genuine quality marker.

The Multi Collagen has a noticeably denser texture due to the eggshell membrane component, which introduces a thicker mouthfeel. It is not unpleasant, but it is perceptible side by side with the single-source products.

The most honest way to compare collagen products is cost-per-10g collagen, because that is what you are actually buying. Marketing positioning, packaging, and brand narrative are secondary to the dose you receive and what you pay for it.

A note on the Ancient + Brave comparison: their serving size is 5g, with a recommendation of 5-10g per day. To reach a comparable 7.5g dose, a buyer uses 1.5 servings per day, which changes the cost-per-10g calculation upward. The figures above use one serving per day (5g collagen) for the Ancient + Brave column to reflect the entry-level cost; at matched 7.5g doses, both Ancient + Brave products cost more per 10g of collagen than Planet Paleo.

Planet Paleo Pure Collagen is the better value bovine option at comparable daily doses against Ancient + Brave True Collagen. At £22.99 for 30 servings of 7.5g, it delivers a higher dose per serving at a lower cost-per-10g when both are used at equivalent daily amounts.

Planet Paleo Marine Collagen costs more per 10g than Ancient + Brave Wild Collagen at matched dose levels. The MSC certification, confirmed sourcing from wild-caught white fish, and the clean taste profile are the differentiators. For buyers who prioritise those specific quality markers, the premium is accounted for. For buyers optimising purely on cost-per-gram, Ancient + Brave Wild Collagen is the leaner choice.

If your priority is dose value and you are using bovine collagen, Planet Paleo Pure Collagen at the 450g size will deliver the best cost-per-10g in this category. If you are choosing marine collagen and MSC certification is important to you, Planet Paleo Marine Collagen remains a strong option despite the category premium.
