Nutrition Geeks sells a collagen powder called Collagen Glow Up, a 420g pack of hydrolysed bovine collagen peptides. This guide sets out what the brand’s own label and product page say, works out the price per serving, and compares the cost per gram of collagen with the other products in our price index. We haven’t tested this product. Everything below comes from the brand’s label and listing as read on 26 October 2026, plus our own arithmetic. Nothing here is a verdict on whether it works, and we have no first-hand experience of how it tastes or mixes.
What the label says
The ingredients list is one line: hydrolysed bovine collagen peptides. The nutrition panel is on the product page.
| Per serving (2 flat tablespoons, 14g) | Amount on the label |
|---|---|
| Protein | 12.6g (90g per 100g) |
| Energy | 211kJ / 50kcal |
| Fat, carbohydrate, sugars | 0g |
| Salt | 0.0007g |
| Glycine | 3,382mg |
| Proline | 1,907mg |
| Hydroxyproline | 1,595mg |
The label also lists 15 other amino acids. Glycine, proline and hydroxyproline are the amino acids collagen is especially rich in, which is why they’re shown here. The page gives the pack as 420g, “1 month supply”, which at 14g a serving is 30 servings.
The front of the pack in the product photo reads “14,000mg collagen peptides”, which matches the 14g serving weight. The nutrition panel’s figure for protein is 12.6g. We’ve used the 12.6g as the collagen figure in the price maths below because it is the number on the panel; using 14g instead would lower each cost per 1,000mg by about 10%.
The page says the collagen is Type I and Type III, sourced from “grass-fed, pasture-raised Brazilian cattle”, and the powder is “virtually odourless and tasteless”. It doesn’t give the proportions of Type I and III.
What the page shows about testing
The page displays a third-party test result dated 24 August 2026, from two named laboratories, reporting that the collagen protein meets its label claim of 14g per serving, with one active verified. The result carries its own caveat that it doesn’t guarantee future performance, stability or shelf life. We haven’t seen the underlying lab report beyond the page’s summary. A label-accuracy test checks what is in the bag, not what the product does.
What it costs
The brand lists one-off and subscription prices, with lower per-pack prices on three- and six-pack deals. The list price shown against them is £19.99.
| Option | Price per pack | Per serving (30 a pack) | Per 1,000mg of collagen protein |
|---|---|---|---|
| One pack, one-off | £16.99 | £0.57 | £0.045 |
| Three packs, one-off (each) | £14.99 | £0.50 | £0.040 |
| Six packs, one-off (each) | £13.99 | £0.47 | £0.037 |
| One pack, subscription | £15.29 | £0.51 | £0.040 |
| Three packs, subscription (each) | £13.49 | £0.45 | £0.036 |
| Six packs, subscription (each) | £12.59 | £0.42 | £0.033 |
For comparison, this is the cost per 1,000mg of collagen across the products in our own UK collagen price index, checked September 2026, with the Nutrition Geeks figure for a single one-off pack:
| Product | Format | Cost per 1,000mg of collagen |
|---|---|---|
| Nutrition Geeks Collagen Glow Up | Bovine powder | about £0.04 |
| Absolute Collagen Premium Marine Powder | Marine powder sachet | about £0.30 |
| Zooki Marine Collagen | Marine liquid sachet | about £0.34 |
| Cloo9 Collagen Jelly | Marine jelly stick | about £0.46 |
| NOW Foods Collagen Jelly Beauty Complex | Bovine jelly stick | about £0.64 |
| BB LAB Pomegranate Collagen S | Marine jelly stick | about £1.29 to £1.71 |
On that one measure, a bulk bovine powder costs a fraction of the other formats. Those figures compare labelled collagen only. They don’t account for taste, convenience, added ingredients, collagen source, or anything about results, and the formats differ in how people use them.
What the brand claims
Reporting a claim isn’t endorsing it. The page’s title calls the product the UK’s best-selling collagen and its text calls it the highest-quality collagen in the UK, which are the brand’s statements and which we haven’t verified. It says collagen accounts for around 70 to 80% of the dermis and that collagen production declines from early adulthood, general statements about collagen rather than about this product. It makes a hair and nail claim for biotin, but the page states that its biotin product is a separate item offered free with some bundles, so that claim isn’t about the collagen powder. The page describes the product as free from “artificial additives and common allergens” without giving an allergen statement.
It doesn’t contain vitamin C. The brand’s FAQ says an earlier version did, and that vitamin C and hyaluronic acid were removed because, in its words, they affected taste, dissolvability and effectiveness. We haven’t seen evidence behind that last point. The one authorised UK/EU claim linking collagen to skin concerns Vitamin C contributing to normal collagen formation, so it isn’t available to this product.
Who should check the label
- Anyone avoiding animal products. It is bovine, and the brand says it is not suitable for vegetarians or vegans.
- Anyone with a specific allergy or dietary requirement. The page says “free from common allergens” but gives no allergen statement, so check the pack itself.
- Anyone taking medication, or who is pregnant or breastfeeding. Ask a pharmacist or GP before starting any supplement. Our guide on taking too much collagen covers the safety record.
Does it work?
We can’t tell from a label, and we haven’t tested it. What we can offer is context. Most of the trials we cover used between 2.5g and 15g of collagen peptides a day, and 12.6g of protein per serving falls inside that range, so the dose isn’t a token amount. That doesn’t tell you this product performs as those trials did. For what the research shows and doesn’t, see do collagen jelly sticks work?, which applies to collagen peptides generally rather than to any one product, and what “hydrolysed collagen” means on a UK label.
What we couldn’t check
We haven’t tried the product. We haven’t read forum threads or summarised customer reviews, and the review counts and ratings on the brand’s own page are the brand’s display, not something we’ve verified. We couldn’t confirm the Type I to Type III proportions, because the page doesn’t give them.
