About Top gut health, greens and collagen compared
This ranking shortlists from 113 brands selling greens, collagen and gut support lines, weighing the price you pay on a first order against the price you pay when a subscription renews, what the range actually contains, and where it can be shipped. Entry prices in this ranking span €2.26 to €105.24, and cost per serving spans €0.01 to €7.45. The main trade-off is that the cheapest shelves and the widest reaching brands are rarely the same company. Prices under €32.44 come mostly from single market pharmacy brands selling their own label, while brands that ship across US, CA and GB or hold GMP, NSF or USP marks charge more per serving. Renewal terms split the list again, because a subscription decides whether the following order costs less than the first. A reader ordering in Sweden, Germany or Brazil is in a different market from a reader ordering in the US, Canada or the UK, so market coverage matters as much as unit price.
How we picked
Every brand here is scored on cost, offer and trust. Cost carries 40%, offer carries 40% and trust carries 20%, so entry price and what you get for it decide most of the order, and certifications, testing, support and the money back window settle the rest. Cost is read from entry price and cost per serving rather than a headline discount. Offer is read from the product types a brand stocks, so a brand holding probiotics, greens and collagen in one catalogue outranks a brand selling a single format. Trust looks at certifications, third party testing, support channels and the length of the money back window. Figures come from each brand's own legal, shipping and product pages, together with the category ranges and proportions behind this ranking. Partner brands are listed first and the remaining brands follow in score order, so the top of the list reflects score rather than a paid place. No brand here needs a membership fee before you can order.
How we rankWhat to look for
- Price at entry
- The median entry price in this ranking is €32.44, with a lower quartile of €17.53 and an upper quartile of €43.41. Prices sitting well under the upper quartile usually come from a single market pharmacy brand selling its own label, so check whether it ships to you.
- Cost per serving
- Median cost per serving in this ranking is €1.10, rising to €1.66 at the upper quartile and falling as low as €0.01. A daily greens blend costs more each month than the entry price suggests, so weigh the per serving figure.
- Gut, greens and collagen formats
- Probiotics appear in 54.9% of the brands in this ranking, collagen in 51.3% and greens in 31.9%. A brand stocking all three lets a gut routine stay with a single brand.
- Certifications and testing
- GMP appears in 59.1% of brands here, NSF in 15.2% and USP in 3%. Third party testing is confirmed for 83.9% of them, so quality marks are common but not universal.
- Diets
- Vegan lines cover 77.5% of this ranking and gluten free 77.5%. Those labels are the most useful filter on a gut health blend, alongside vegetarian where a plant based capsule is not required.
- Delivery and support
- Free delivery covers 100% of the brands here, phone support 67.3% and email 94.5%. Where a brand lists fewer channels, questions about a first order take longer to settle.
