On kefir and osteoarthritis we claim nothing, and legally nobody can. No health claim about kefir is authorised in the European Union. Kefir is a fermented food, not a treatment. This page explains the framework, describes what the drink actually is, and sends the medical question back to your doctor.
The figures on this page
This page has been rewritten. The previous version stated that kefir helped reduce inflammation and relieve joint pain. That wording is not permitted, and we do not keep it.
In the European Union, regulation 1924/2006 governs nutrition and health claims made about foods. A health claim may only be used if it appears in the register held by the European Food Safety Authority.
For kefir, that register holds nothing. No authorised claim, not about joints, not about inflammation, not about anything else. Saying otherwise on a sales page is an infringement, and it is also false information given to someone in pain.
The word probiotic itself is treated as a health claim in several EU countries, and its commercial use is restricted. That is why you will not find it on our pages describing our cultures.
We were in the first case on this very page, and it is now corrected.
Everything below replaces what the old version of this kefir and osteoarthritis page asserted. It is drier reading, and every line of it can be checked in your own kitchen.
Everything about the product and how it is made. It is verifiable, it is useful, and it commits us to no promise.
| What goes in | Water kefir, 1 litre | Milk kefir, 1 litre |
|---|---|---|
| Culture | 30 g of grains | 10 to 20 g of grains |
| Liquid | 1 litre of unchlorinated water | 1 litre of milk |
| Sugar | 4 tablespoons, about 60 g | none, lactose is enough |
| Dried fruit | 1 fig or 2 dried apricots | none |
| Citrus | 1 lemon or 1 orange | none |
| Duration | 24 h, up to 48 h | 24 h |
| Temperature | 20 to 25 °C | 20 to 25 °C |
A 200 ml glass of water kefir is 30 to 50 kcal and holds about 3 to 4 g of sugar per 100 ml after 24 hours. A glass of milk kefir is 110 to 130 kcal. Both contain traces of alcohol, 0.2 to 1 per cent. These are orders of magnitude, because a homemade drink is never analysed.
This is the part of kefir and osteoarthritis that is not ours to write.
Osteoarthritis is a joint condition followed medically. Its diagnosis, its course and its management belong to a doctor, and to nobody else.
For general information about the condition, public health sources exist and are free. To know what a food may or may not claim, the European Food Safety Authority register is available online.
One important point. If you are on a treatment, no change is decided from a web page, whichever one it is. That applies to ours as much as to the ones promising miracles.
«Does it work?» We do not know, and we are not allowed to discuss it. The question belongs to a doctor who knows your history.
«I read that it does elsewhere.» Very possibly. Many pages repeat prohibited wording, often in good faith, by copying. A widespread statement is not therefore a true one, nor a legal one.
«Why say nothing, when you sell the stuff?» Precisely for that reason. A seller promising an effect on a disease is both outside the law and judge in his own case. We would rather explain fermentation, which we do know.
«Is there any risk in drinking it?» For most people kefir is an ordinary drink. It contains traces of alcohol, 0.2 to 1 per cent, which is worth knowing. For a particular case, again, ask your doctor.
Apply these four tests to this page and it passes. Apply them to the previous version of this same page and it failed the first two. That is why it was rewritten.
| Previous wording | Why it is a problem |
|---|---|
| «the superfood to relieve your joints» | promise of an effect on a disease, in the title and the URL |
| «anti-inflammatory properties» | unauthorised health claim |
| «helps reduce inflammation» | therapeutic effect asserted |
| «supports bone health» | claim not in the register |
| «rich in probiotics» | restricted term, treated as a claim |
None of those sentences was written in bad faith. They came from copied articles. That is exactly what makes kefir and osteoarthritis a difficult subject, and why this page now explains the framework instead of promising a result.
Leaving kefir and osteoarthritis aside, here is the part we are competent to answer.
With those five points a culture lasts for years. Surplus grains appear within three to six weeks, and they can be dried as a reserve or used to start a second jar. That is exactly the extent of what a seller of cultures can offer you.
If we remove every health claim from a page like this one, the question becomes fair. What is left to say? Quite a lot, as it turns out, and all of it useful.
Live grains, not a powder. A sachet of freeze dried ferment makes a few litres and then it is finished. Live grains multiply. From 30 g you will have surplus within three to six weeks, and that surplus starts another jar or goes to a friend. One purchase, years of drink. That is the actual argument, and it needs no mention of kefir and osteoarthritis.
Knowing what normal looks like. A jar that smells of yeast is normal. A film of white foam on the surface is normal. Grains that float are normal. Grains that have turned to mush, or a jar that smells of nail varnish, are not. Telling the two apart is what a seller who ferments every day can teach you, and it is worth more than a promise.
Honest limits. We do not know the microorganism count of your jar, because nobody analyses a kitchen preparation. We do not know how a given person reacts to a fermented drink. We do know that it contains traces of alcohol, and we write that down even though it costs us sales to people who cannot drink any.
That is the whole offer. It is narrower than what the previous version of this page suggested, and it is the honest width.
The health claims authorised in the European Union are listed in the register of the European Food Safety Authority. Domestic hygiene guidance is published by the Food Standards Agency.
Live cultures, water and milk
Shipped hydrated and active, ready for the first cycle on the day they arrive.
See the culturesIf you came here looking for a solution to joint pain, we are sorry not to have one to offer. It would be easy to write, and it would be false.
What we can offer is a pleasant fermented drink, a recipe that fits in four lines, and a culture that lasts for years. Nothing more, and that is already something.
And if this page has been useful in one way, let it be this one. The next time you read that a food relieves a named disease, check the register before you believe it. That single habit protects you from most of what is written online about kefir and osteoarthritis, and from a good deal of what is written about every other food as well. It costs two minutes, the register is public and free, and it is the only test that does not depend on who is selling.
When someone types kefir and osteoarthritis into a search box, they are usually asking one of three different things, and only one of them has an answer we can give.
| The real question | Who answers it | What we can do |
|---|---|---|
| «Will this help my joints?» | your doctor | nothing, and we will not pretend |
| «Is it safe for me to drink?» | your doctor, with your file | describe the drink: acids, sugars, traces of alcohol |
| «What is kefir, actually?» | us | the whole recipe, in detail |
The third row is the only one where a seller of cultures adds anything. The first two are the ones most pages about kefir and osteoarthritis answer anyway, and that is the problem.
This is measurable, so we can write it. Over 24 hours at 20 to 25 °C, the culture consumes part of the added sugar and produces acids, carbon dioxide and a small amount of alcohol. The pH falls, the taste turns from sweet to tart, and the liquid starts to fizz.
Notice what is not in that list. Any statement about the body. The chemistry of the jar is observable. What happens after you drink it is not something a culture seller measures, and certainly not something we would publish as fact.
Cutting the sugar. People who come to kefir from a health page often halve the sugar, because the page told them sugar was the enemy. The culture then starves, the grains stop multiplying, and within three cycles the jar is dead. The sugar feeds the grains, not the drinker. After 24 hours most of it is gone. For a less sweet result, ferment longer rather than adding less.
Treating it as a course of treatment. Drinking a litre a day for two weeks and then stopping is the pattern of someone following a remedy, and it comes straight from pages that present kefir and osteoarthritis as cause and cure. Kefir is a drink. A glass with a meal, when you feel like one, is the whole of it.
Both mistakes have the same origin. A page that promised something. That is the practical cost of unauthorised claims, beyond the legal one.
We cannot say so, and legally nobody can. No health claim about kefir appears in the register held by the European Food Safety Authority. Kefir is a fermented food, not a treatment, and osteoarthritis is followed medically.
Because many pages, commercial ones included, repeat prohibited wording without checking. EU regulation 1924/2006 strictly limits what a food seller may say. A page promising relief from a named disease is outside the law, which also says something about the rest of it.
There is work on fermented foods in general, at very uneven levels of proof. None has led the European Food Safety Authority to authorise a claim for kefir. A single study is a lead, not proof, and it is not medical advice.
That is a question for your doctor, not for us. What we can say. Kefir is an ordinary fermented drink, it contains traces of alcohol of 0.2 to 1 per cent, and its preparation is described below.
No, under no circumstances. No food replaces a prescribed treatment. If you are on one, any change is discussed with the doctor who prescribed it.
A fermented food. Live grains turn sweetened water or milk into a drink in 24 hours, at 20 to 25 °C. For water kefir: 30 g of grains and 4 tablespoons of sugar per litre. For milk kefir: 10 to 20 g of grains per litre, with no added sugar.
Water or milk, unconsumed sugars, acids produced by fermentation, carbon dioxide and traces of alcohol. A 200 ml glass of water kefir is 30 to 50 kcal, a glass of milk kefir 110 to 130 kcal. These are orders of magnitude, not an analysis.
From your doctor for your own case, and from the European Food Safety Authority register to see what is authorised. A systematic review is stronger than a single study, and an online shop has a commercial interest by definition.
Because the question gets asked, and an honest answer beats a page that promises. It explains the framework, describes the product, and points to the only legitimate source on a health question.
No. It is a fermented food. The health claims authorised in the European Union are listed in the register of the European Food Safety Authority, and none of them concerns treating a disease.
