We analysed 70 top-ranking blood sugar pages. Not one explained mitochondria.
Brittica research · Published 3 November 2026 · 9-minute read
The short version. Using reputable search engines and analytics software, we read every editorial page we could retrieve from the top UK results for 16 common blood sugar searches [7][8][9]: 70 pages in total, from the NHS and Diabetes UK to supplement retailers and medical journals. Here is what we found.
- Not one page explains mitochondria, the cell engines whose decline shows up in muscle years before blood sugar rises.
- Only 4 of 70 (6%) explain glucagon, the hormone that tells the liver to release sugar and stays too high in type 2 diabetes.
- No page explains all five core players: insulin-making beta cells, glucagon-making alpha cells, the liver, muscle and fat.
- One in three (23 of 70) explains blood sugar as a problem involving three or more organs. That share falls to one in five on the pages people read when they want to act: how to lower blood sugar, and which supplement to buy.
- On YouTube it gets worse. Across 63 top videos with 66 million views, those promising one fix as the answer take 62% of the views. Videos explaining how type 2 diabetes works take 3%.
- 14 of 20 search results for Facebook and LinkedIn posts about berberine were spam pages planted on unrelated websites.

Why we looked
Type 2 diabetes does not start in one place. The pancreas’s beta cells tire, its alpha cells keep releasing glucagon, the liver keeps making sugar, muscle stops answering insulin, fat stores overflow, and the mitochondria inside all of them slow down [1][2][3]. That is why NICE now starts most people on two medicines that act on different organs [4].
So we asked a simple question. When someone in the UK searches for help with their blood sugar, does the page they land on tell them this? Or does it hand them a list and move on?
How we did it
- Searches. 16 common UK searches about blood sugar: how to lower blood sugar (and how to lower it naturally), foods that lower blood sugar, high blood sugar symptoms, what causes type 2 diabetes, insulin resistance, how to reverse insulin resistance, prediabetes, how to reverse type 2 diabetes, type 2 diabetes treatment, metformin alternatives, natural remedies for type 2 diabetes, best supplement for blood sugar, blood sugar supplements uk, berberine for blood sugar, and berberine vs metformin.
- Results. We use reputable search engines and analytics software to collect the organic results people in the UK see [7][8][9]. Results were collected on 2 and 3 November 2026. Ten searches were read to the top 20 and six to the top 10.
- Sample. We removed duplicates, videos, forums and shop pages, then read every editorial page we could retrieve. That gave 70 pages.
- Coding. Each page was coded for how it frames the problem and which organs it explains. An organ only counted if the page explained what it does to blood sugar. Naming it was not enough.
| Framing | What it means |
|---|---|
| Single answer | Presents one food, ingredient, product or programme as the answer |
| List of tips | Several tips or products, without explaining how they work on different parts of the body |
| Multi-organ | Explains the role of at least three organs and recommends combining approaches that act on them |
| Multi-organ (light) | Recommends combining approaches but explains only one or two organs |
What we found
Most pages give you a list, not a reason
| Framing | Pages | Share |
|---|---|---|
| List of tips | 32 | 46% |
| Multi-organ (three or more organs) | 23 | 33% |
| Single answer | 8 | 11% |
| Multi-organ (light) | 7 | 10% |
The average page explained the role of two organs. Nineteen pages (27%) explained none at all: they told readers what to eat or do without saying what happens inside the body.
Insulin and muscle get the airtime. Glucagon, the brain and mitochondria do not.
Half the pages explained insulin from the beta cells. Four in ten explained muscle insulin resistance or the liver. After that, coverage drops fast. The kidneys, which hold on to more sugar in type 2 diabetes and are the target of SGLT2 medicines [5], appear on 8 pages. Glucagon, described by leading researchers as half of the problem [3], appears on 4. The brain, which helps set appetite and the liver’s sugar output [6], appears on 2.
Mitochondria appear on none. Yet in young, lean adults whose parents have type 2 diabetes, muscle mitochondria were already about 30% less active, and insulin resistance already present, before blood sugar rose [2].
Quick fact: Of 70 top-ranking UK web pages about blood sugar, none explained mitochondria and only four explained glucagon.
Where the gap is widest
| Type of search | Pages | Multi-organ | Single answer | Organs explained (average) |
|---|---|---|---|---|
| Causes, insulin resistance, prediabetes | 17 | 9 (53%) | 0 | 2.6 |
| Treatment, metformin, remission | 15 | 6 (40%) | 3 | 2.3 |
| Supplements, natural remedies, berberine | 22 | 5 (23%) | 5 | 1.8 |
| How to lower blood sugar, food, symptoms | 16 | 3 (19%) | 0 | 1.6 |
The pattern is clear. Pages that explain why blood sugar rises (causes, insulin resistance) usually describe several organs. Pages that tell you what to do about it mostly do not. And the supplement and berberine results are where single-answer framing concentrates: 5 of the 8 single-answer pages in the whole sample sit there.
UK publishers are not ahead. Of 26 pages from UK organisations (the NHS, NICE, Diabetes UK, the BHF, Bupa and UK pharmacies), 5 (19%) met the multi-organ bar. NHS and Diabetes UK pages are accurate and safe, but most are written as practical checklists rather than explanations.
A note on our first pass. In an earlier sample of 25 pages from 8 searches, only 16% met the multi-organ bar. Widening the study to include causes and insulin resistance searches doubled the share, because those pages exist to explain. The gap on the pages people use to act did not close.
What social media says: YouTube, Facebook and LinkedIn
Plenty of people never open a web page about their blood sugar. They watch a video or scroll a feed. So we ran the same test on social media.
How we did it
- YouTube. YouTube UK search results for four searches (how to lower blood sugar, how to reverse type 2 diabetes, best supplement for blood sugar, berberine blood sugar), collected on 3 November 2026 with the same search and analytics tools [8]. After removing duplicates and non-English videos, that gave 63 videos with 66 million views between them. We coded each one from its title and description, the part a viewer sees before pressing play, and read one full transcript as a check.
- Facebook and LinkedIn. Neither platform lets outsiders search public posts at scale, so we ran site-restricted searches on a reputable search engine, three per platform, and coded the post text shown in the results [7].
YouTube: the one-fix promise wins the views
- 38% of videos promise one fix as the answer (“#1 absolute best way”, “the only supplement”, “this lowers blood sugar faster than anything else”). Those videos hold 62% of all views.
- 68% use sensational packaging such as secret, hidden, #1, fastest, instantly or must. They hold 76% of views.
- Only 8 videos (13%) set out to explain how type 2 diabetes works, including two interviews with Professor Roy Taylor, whose research underpins NHS remission programmes. They hold 3% of views.
- The typical one-fix video has about 740,000 views. The typical explainer has about 140,000, roughly five times fewer.
- 38% carry product, affiliate or programme links in the description: supplements, electrolytes, glucose monitors, protocols and paid coaching.
- For “how to lower blood sugar”, none of the top 20 videos was an explainer, and 19 of 20 used sensational packaging.
The transcript we checked shows how this plays out. A video titled “The hidden secret to lowering your blood sugar fast” (190,000 views) presents a 10-minute walk after meals as a secret that “has nothing to do with adjusting your diet or starting new medications”. Walking after meals does help, because working muscle takes in sugar without needing insulin. But the video explains one organ, muscle, and frames it as the whole answer.
UK institutions are almost absent. The only NHS video in the results was about low blood sugar. Diabetes.co.uk and ITV’s This Morning were the only UK sources in the reversal results.
Facebook and LinkedIn: one lever at a time
On Facebook, the nine posts we could identify were mostly news about remission: Diabetes UK, BBC Breakfast and Newcastle University, all built around one lever, a very low-calorie diet. They were accurate, but none explained in the visible text which organs recover and why. One group post told readers that 80% of people with type 2 diabetes can go into remission, without a source.
On LinkedIn, most of the twelve posts were single tips from health professionals: walk for three minutes after eating, fidget, take a hot bath (“proven”, according to the post). One post explained what insulin does across the body, from triglycerides to muscle.
The berberine spam problem
When we searched for Facebook and LinkedIn posts about berberine and blood sugar, 14 of the 20 results were not on Facebook or LinkedIn at all. They showed the hallmarks of spam pages planted on unrelated university, government and business websites, from a Brazilian journal platform to a Scottish ski centre and a Korean archive. Readers looking for berberine advice are being served content nobody stands behind.
Quick fact: on YouTube, videos promising one fix for blood sugar take 62% of the views. Videos explaining how type 2 diabetes works take 3%.
What this means if you are managing your blood sugar
If you have been told to eat better, move more and take your tablets, and your numbers still creep up, the advice was not wrong. It was incomplete. Blood sugar is set by a network of organs, and lasting change comes from acting on several of them at once.
Be most careful on video and social feeds. That is where the single-fix promise gets the most views, and where the people selling it are most likely to have a product link in the description.
That is also the test to apply to any supplement. Ask which organs each ingredient acts on, and whether the label shows the dose. A capsule built around one ingredient can only reach one part of the problem.
We wrote two guides to fill the gap our research found:
- What causes type 2 diabetes: the organs behind high blood sugar, with a diagram of how one failure triggers the next.
- Metformin vs berberine, mapping every treatment, prescription and natural, to the organs it reaches.
And it is the thinking behind GlycoShift: 11 ingredients chosen for mitochondria, insulin sensitivity, the liver and the pancreas, every dose on the label, supporting natural blood sugar balance.*
*Chromium contributes to the maintenance of normal blood glucose levels.
Limitations
- This is a snapshot of UK search results on two days. Rankings change and results vary by device and location.
- Seventy pages is a modest sample. Some results could not be retrieved, and three pages were coded from search summaries and one from the published paper.
- One team coded every page against fixed definitions, without independent double-coding.
- Trial and review pages about a single compound are single-focus by design. We kept them because they rank for consumer searches.
- YouTube videos were coded from their titles and descriptions, not full transcripts, so we report what they promise rather than which organs they explain. YouTube results are personalised and change quickly.
- Facebook and LinkedIn do not allow outside searches of public posts at scale. The 21 posts we coded are the ones search engines surface, judged on the text shown in the results, so treat those findings as indicative.
- We sell a blood sugar supplement. Our full page-by-page coding is available to journalists and researchers on request.
