Every correction we have published on a guide, newest first. 83 corrections across 62 guides. None of them is ever removed.
We sell a beef organ supplement and we publish health guides about beef organs. That is a reason to check what we tell you, not to take it on trust, and a page that has never admitted to being wrong is indistinguishable from a page that hides it. So this is the list.
Most of what is below came out of a citation audit on 27 August 2026, when every PubMed, PMC and DOI identifier printed anywhere in the guides was resolved against NCBI and Crossref. Some references named one paper and linked another. Some gave a real paper someone else’s authors. Some claims turned out not to be in the source they cited at all, and those claims were cut rather than re-sourced to something more convenient. Each fix is recorded on the guide it was made on, and again here.
A build gate now fails on the class of error each of these describes, so the same mistake cannot ship twice, and every reference on every guide prints what its identifier actually opens underneath it.
27 August 2026
A Day on a Regenerative Farm
- 27 August 2026. Reference 1 printed DOI 10.2134/agronj14.0335 for the Sanderson pasture mixtures study. That DOI resolves to a study of corn under nitrogen and irrigation. The correct DOI, 10.2134/agronj15.0259, replaces it.
- 27 August 2026. Reference 3 named the 2015 hyponatremia consensus statement, but its link opens Rosner's 2019 review. The entry now leads with the linked review and names the consensus statement as also consulted.
- 27 August 2026. Three footnote links on this page were unterminated in the markup, which swallowed the paragraph after each of them in a browser. All three are fixed, and each was attached to a claim its reference did not carry, so the sentences were cut back to what the taurine review actually reports.
- 27 August 2026. “The CoQ10 from beef heart is more bioavailable than synthetic CoQ10” and an absorption figure of 30 to 40 percent for supplements were both removed. Neither is in the reviews cited here.
- 27 August 2026. The CoQ10 content of beef heart was given as 10 to 15 mg per 100 g, credited in the sentence to “Mattila et al. 2000”, a work that was not in this page's reference list, so the reader could not check it. Both the figure and the phantom credit are gone. The page now cites only the food-composition review it actually lists, and says plainly that USDA FoodData Central carries no CoQ10 value for beef heart.
- 27 August 2026. “By 60, you might be producing 25% less CoQ10 than you were at 25” was removed. The figure is not in the review it was credited to and we could not source it anywhere. The page now says levels fall with age and gives no number.
- 27 August 2026. Reference 5 led with a taurine review whose link opened a different paper. The linked paper (Jong, Sandal and Schaffer, Molecules 2021) is now the entry, and the other work is named as also consulted.
- 27 August 2026. References 1 and 3 each named a paper their links do not open. Both now name the record the reader lands on, including the low-FODMAP entry, which is a narrative review rather than the network meta-analysis previously printed.
27 August 2026
Bone Broth vs Collagen Supplements: Do You Need Both?
- 27 August 2026. Reference 4 led with a paper on caffeine in tea and linked a paper on metals in bone broth. The linked paper now leads the entry.
- 27 August 2026. Reference 1 named two works and linked a third. It now leads with the work its link opens.
- 27 August 2026. The claim that IgG is “roughly 50 to 60% of the immunoglobulin content” was removed. The cited review gives no such share; it gives the 50 mg per millilitre adequacy threshold, which is what the sentence now says.
27 August 2026
Building Immune Resilience with Whole Food Nutrition
- 27 August 2026. Reference 5 was credited to “Arslan A, et al.” The record is by Ahmann, Steinhoff-Wagner and Büscher. Corrected.
- 27 August 2026. Reference 2 carried no authors. Duan, Sun, Chen, Wang and Yan were added from the record.
27 August 2026
Can I Take Organised While Fasting?
- 27 August 2026. This page described its evidence as “a comprehensive 2024 meta-analysis”. The only thing in its reference list is a single 12-month randomised trial from 2022 in the New England Journal of Medicine, and no meta-analysis of any year appears anywhere on the page. The sentence now describes that trial, its size and its result, and says that one trial is not the whole evidence base.
27 August 2026
Can You Get Enough Collagen from Food Alone?
- 27 August 2026. Reference 3 named two meta-analyses and linked only the second. Both now carry their own identifier.
- 27 August 2026. The claim that participants were women with existing hair thinning was removed: the paper does not say so. The trial's authors are all employed by the company whose supplement was tested, which the page now states.
- 27 August 2026. The 27.6% increase in hair count is marked p = n.s. in the paper, meaning not statistically significant. The page presented it as the finding and did not disclose this. It now does, and reports the outcomes that did reach significance instead.
27 August 2026
Collagen and Hair Growth: Separating Fact from Hype
- 27 August 2026. “The dermal layer of your skin, which is 70% collagen” was removed. The cited review of dermal fibroblasts reports no collagen percentage, and the note calling it a “review of dermal collagen content” was wrong about the source. Both were corrected.
- 27 August 2026. The trial's dose (2.5 g of collagen peptides in a blend, not 10 g alone), its blinding (blind, not double-blind), its size (72 women, not 140) and its population were all misstated, and the absolute elasticity values quoted were not in the paper. The section was rewritten from the record, and the trial's commercial sponsorship is now stated.
- 27 August 2026. The 52.3% elasticity figure this page was built around does not appear in the trial it was credited to. It has been removed from the page, including from the headings and the summary.
27 August 2026
Collagen for Anti-Ageing: What the Clinical Trials Show
- 27 August 2026. Reference 2 named the de Miranda meta-analysis and linked a different one. It now links de Miranda's own record.
27 August 2026
Collagen for Joint Pain: What Does the Evidence Say?
- 27 August 2026. Reference 3 was credited to “Liu Y, Liu S, Luo F, et al.” The meta-analysis is by Lin et al., Journal of Orthopaedic Surgery and Research 2023. Corrected.
- 27 August 2026. Reference 5 carried no authors. The record's authors were added.
- 27 August 2026. Reference 3 named the de Miranda meta-analysis and linked a different one. It now links de Miranda's own record (PMID 33742704).
- 27 August 2026. “A single molecule of HA can bind up to 1,000 times its weight in water” is not in the review it was credited to, which states no water-binding multiple at all. The number has been removed rather than re-attributed.
- 27 August 2026. Reference 1 was credited to “Arslan A, et al.” The record is by Ahmann, Steinhoff-Wagner and Büscher. Corrected.
- 27 August 2026. The claim that IgG is “85 to 95% of total immunoglobulins” was removed. The cited review does not report a share.
- 27 August 2026. References 2 and 3 were credited to authors and journals that are not on their records. Both now name what their links open.
27 August 2026
Colostrum Research: What's New and What's Coming
- 27 August 2026. Reference 1 was credited to “Arslan A, et al.” The record is by Ahmann, Steinhoff-Wagner and Büscher. Corrected.
- 27 August 2026. The claim that ubiquinone is absorbed at “only 1 to 3 percent”, and the 10 to 15 percent figure after it, were removed. The cited review reports dietary intake and fortification strategy, not an absorption rate.
- 27 August 2026. The page described “a 2019 systematic review in the journal Nutrients”. Its footnote opens de Miranda, Weimer and Rossi in the International Journal of Dermatology, 2021: wrong year, wrong journal, and no 2019 Nutrients review exists in the reference list. The paragraph now describes the review the link actually opens, with its size, its population and its industry funding.
27 August 2026
Endometriosis and Nutrition: An Evidence-Based Approach
- 27 August 2026. Reference 2 gave a real paper somebody else's byline: it is by Liu, Wang, Bai, Zhang and Wang, not Nodler et al. Corrected.
27 August 2026
Folate vs Folic Acid: Why the Form Matters in Pregnancy
- 27 August 2026. Reference 3 pointed at an unnamed “active folate vs folic acid review”. It is by Carboni, and now leads the entry.
27 August 2026
Freeze-Dried vs Fresh Organs: Does the Method Matter?
- 27 August 2026. Reference 2 named a 2022 freeze-drying review in Critical Reviews in Food Science and Nutrition, but its identifier opened Ma et al., Saudi Journal of Biological Sciences 2018. The entry now names the paper the link opens.
27 August 2026
Growth Factors in Colostrum: What Are IGF-1 and IGF-2?
- 27 August 2026. Reference 2 was credited to “Arslan A, et al.” in Animals. The record is by Yalçıntaş et al. in Nutrients 2024. Corrected.
27 August 2026
How Blood Sugar Instability Wrecks Your Hormones
- 27 August 2026. Reference 3 named a paper by Whirledge and Cidlowski. Its link opens “Stress and hormones” by Ranabir and Reetu. Corrected.
- 27 August 2026. Reference 1 led with a paper on testosterone and SHBG and linked a paper on estrogens and energy balance. The linked paper now leads the entry.
27 August 2026
How Liver Supports Oestrogen Detoxification
- 27 August 2026. “Cruciferous vegetables contain compounds that inhibit beta-glucuronidase” is not a mechanism the cited review describes; that one is normally attributed to calcium-D-glucarate. The page now reports what Higdon et al. do cover, that indole-3-carbinol and DIM alter urinary oestrogen metabolite profiles in women, and that what the shift means for health is not established.
27 August 2026
How Organised Is Made: From Farm to Pouch
- 27 August 2026. Reference 1 led with a 2009 paper on ice morphology and linked Bhatta et al. on freeze-drying. The entry now names the paper the link opens.
- 27 August 2026. Reference 2 led with a textbook and linked a journal paper. The linked paper (Bonfante and Genre, Nature Communications 2010) now leads the entry.
27 August 2026
How Stress Affects Fertility (And What to Do About It)
- 27 August 2026. Reference 1 named a paper by Whirledge and Cidlowski in Minerva Endocrinologica. Its link opens “Stress and hormones” by Ranabir and Reetu. The entry now names the paper the link opens.
27 August 2026
How Stress Destroys Your Gut (And What to Do About It)
- 27 August 2026. Reference 2 attributed the linked permeability review to Karl et al. in a journal it was not published in. It is by La Torre, Van Oudenhove, Vanuytsel and Verbeke, in Neurobiology of Stress 2023.
27 August 2026
How to Read a Nutritional Study Without Being Misled
- 27 August 2026. Reference 2 led with a philosophy paper and linked a clinical one. The linked paper now leads the entry.
27 August 2026
How to Recognise the Early Signs of Poor Gut Health
- 27 August 2026. Reference 2 named Fasano's Physiological Reviews paper on zonulin but linked a different Fasano paper. It now links the paper it names.
27 August 2026
Morning Routines That Set Your Family Up for the Day
- 27 August 2026. “A screen-free morning improves attention capacity in class by 20 to 30 percent” was removed. The cited cohort study measured weekly screen hours against a developmental screening test in under-fives. It has no morning exposure, no classroom outcome and no such percentage. The surrounding claims that rested on it were cut back with it.
27 August 2026
Nutrition for Your 70s, 80s and Beyond
- 27 August 2026. Reference 2 pointed at an unnamed “age-related gastric secretion review”. It is by Vara-Luiz et al. and now leads the entry.
27 August 2026
Organised Protein Pancakes: A Weekend Favourite
- 27 August 2026. “Unlike whey isolate, Beef protein is a complete protein” was false on its face (whey isolate is a complete protein), and the review cited for it makes no comparison between the two. The sentence is gone. The page now says the case for beef protein here is that it carries no dairy, and cites the review for what it actually establishes: protein intake targets and the role of leucine.
27 August 2026
Perimenopause Nutrition: What Changes and What to Eat
- 27 August 2026. “These four things alone prevent almost all perimenopause-related bone loss” and the claim that a woman doing them would have denser bones at 70 than one relying on medication were both removed. We have no source for either, and the review cited here notes there are no established guidelines for preventing osteoporosis in perimenopausal women specifically.
- 27 August 2026. A daily protein target of 150 grams appeared three times on this page with no source of any kind. It is gone. In its place the page cites the PROT-AGE position paper (1.0 to 1.2 g per kg of body weight a day, more when exercising, less with severe kidney disease) and states plainly that those recommendations are for people over 65 and not for perimenopause.
- 27 August 2026. This page told women twice that they lose bone “if nutrition is inadequate”, which reverses what its own source says. The cited review attributes accelerated bone loss to the loss of ovarian function, greatest in the year before the final period and the two years after, and treats calcium and vitamin D as clinical management rather than as the trigger. Both sentences were rewritten. The rate attached to them, 1 to 3 percent a year, is not in the source and has been removed.
- 27 August 2026. Reference 1 pointed at an unnamed “Bone and the Perimenopause review”. It is by Lo, Burnett-Bowie and Finkelstein, and is now named in full.
27 August 2026
Pre-Workout Nutrition Without the Chemicals
- 27 August 2026. “Artificial colours and dyes… are banned in several European countries” was removed. We have no source for it.
- 27 August 2026. Aspartame was named alongside sucralose as disrupting glucose metabolism. In the trial cited (Suez et al., Cell 2022) all four sweeteners altered the microbiome but only saccharin and sucralose significantly impaired glycemic responses. Aspartame was one of the two that did not, and the page now says so.
27 August 2026
Pure Maple Syrup: More Than Just a Sweetener
- 27 August 2026. Reference 1 was credited to “Mohammed F, et al.” in Foods. The record is by Saraiva et al. in the International Journal of Environmental Research and Public Health. Corrected.
27 August 2026
Soil Health: Why It Matters for Your Health Too
- 27 August 2026. Reference 3 led with a textbook and linked a journal paper. The linked paper now leads the entry.
- 27 August 2026. Reference 2 credited the iron recycling review to Klei et al. It is by Slusarczyk and Mleczko-Sanecka, in Genes 2021. Corrected.
- 27 August 2026. Reference 1 credited the tuftsin overview to Najjar and Konopinska. PubMed records one author on it, Najjar. The second name was removed.
27 August 2026
The Antimicrobial Power of Raw Honey
- 27 August 2026. Reference 1 named a Brudzynski paper and linked a 2025 review by Ogwu and Izah. The entry now names the linked review.
27 August 2026
The Complete Guide to Beef Organ Supplements
- 27 August 2026. This page used to give capsule counts by goal, including two to three capsules three times daily to correct a deficiency, and a number of weeks it would take. Every one of those numbers was deleted. We could not source any of them, nobody here is a clinician, and capsule contents differ so widely between brands that a capsule count is not a dose. The public intake references and the arithmetic to apply them to a label are what stands in their place.
27 August 2026
The Connection Between Nutrition and Autoimmune Disease
- 27 August 2026. Reference 2 named Fasano's Physiological Reviews paper on zonulin but linked a different Fasano paper. It now links the paper it names.
- 27 August 2026. Reference 1 listed an author, Negulescu, who is not on the record Crossref returns for that preprint. The byline was corrected and the entry now says plainly that it is a preprint.
27 August 2026
The Gut Lining: How It Works and How to Protect It
- 27 August 2026. Reference 1 named Fasano's Physiological Reviews paper on zonulin but linked a different Fasano paper in a different journal. It now links the paper it names.
27 August 2026
The Role of Zinc in Over 300 Enzymatic Reactions
- 27 August 2026. Reference 4 linked a paper by Allouche-Fitoussi and Breitbart under Fallah's name. It now links Fallah's own record.
- 27 August 2026. The claim that the cholesterol-to-pregnenolone enzyme and the testosterone-to-DHT enzyme are zinc-dependent was removed. The cited review is about male fertility and does not establish either step.
27 August 2026
The Science Behind Organised: Every Claim, Every Study
- 27 August 2026. Reference 1 named two meta-analyses and linked only the second. Both now carry their own identifier.
- 27 August 2026. Reference 3 credited a vitamin K2 link to Theuwissen et al. That record is by El Asmar, Naoum and Arbid. Corrected.
27 August 2026
Travel Nutrition: How to Stay Nourished on the Go
- 27 August 2026. “A high-protein, high-fat breakfast immediately on arrival signals to your body that a new day has started” was footnoted to Eastman and Burgess on jet lag. That paper is entirely about timed bright light and melatonin and does not discuss food composition at all. The claim that a breakfast resets your circadian clock has been removed, along with the product suggestion attached to it. The page now says what the source supports and says plainly that we could not find a trial for the food claim.
27 August 2026
Type II Collagen and Cartilage: What the Research Shows
- 27 August 2026. Reference 3 listed an author, Lerman RH, who is not on the record.
- 27 August 2026. The two UC-II trials were described the wrong way round: the knee osteoarthritis trial was presented as a study in athletes. Both sentences now describe the trial they cite, with its population and duration.
27 August 2026
Vitamin K2: The Nutrient Nobody Talks About
- 27 August 2026. Reference 1 credited a vitamin K2 link to Theuwissen et al. That record is by El Asmar, Naoum and Arbid. Corrected.
- 27 August 2026. “Magnesium oxide has notoriously poor bioavailability” was contradicted by the very trial cited for it: Schuette et al. found no difference between magnesium diglycinate and magnesium oxide for the patient group as a whole (23.5% against 22.8%), with the chelate ahead only in the four most malabsorptive patients. The paragraph now reports what both cited papers found, including that the second one reports no result specific to magnesium oxide at all.
- 27 August 2026. Reference 5 pointed at a magnesium bioavailability paper under the wrong journal and with no authors. It is by Blancquaert, Vervaet and Derave, in Nutrients 2019.
27 August 2026
What to Eat for Muscle Recovery (Beyond Protein Shakes)
- 27 August 2026. “Trials of collagen peptide supplementation alongside vitamin C have shown improvements in collagen synthesis biomarkers and tendon outcomes in athletes” overstated the single study cited. Shaw et al. is eight healthy men doing rope-skipping: the biomarker half holds up, but the mechanical improvements were measured in engineered ligaments treated in vitro with the men's serum, not in anybody's tendons. The page now describes the study as it was run.
- 27 August 2026. A pull quote giving a 15 percent fall in broccoli calcium and a 20 percent fall in iron as “documented fact” was replaced. Those figures are not in the cited study and we could not source them.
- 27 August 2026. “Across the board, minerals like calcium, magnesium, iron, and copper had declined significantly” overstated the study it cites. Davis, Epp and Riordan report statistically reliable declines for six nutrients only (protein, calcium, phosphorus, iron, riboflavin and ascorbic acid) and no reliable change for the other seven, which is where magnesium and copper sit. The page now names the six, says the other seven did not move, and reports that about 28 percent of the individual ratios go up rather than down.
27 August 2026
Why Prenatal Vitamins Aren't Always Enough
- 27 August 2026. “Choline supplementation during pregnancy is associated with better memory, faster processing speed, and stronger attention in the child” named three outcomes where the cited trial found one. Caudill et al. randomised 26 women and tested 24 infants: mean reaction time was significantly faster, visuospatial memory was tested with no benefit reported, and attention was never measured. The page now reports the trial's size and its actual result, and says that choline dosing in pregnancy is a question for a midwife or doctor.
27 August 2026
Why We Stopped Being Afraid of Salt (And You Should Too)
- 27 August 2026. The PURE analysis cited here enrolled 101,945 people in 17 countries, not “over 130,000”. The figure was corrected; the J-shaped curve and the 3 to 6 g optimum are as the paper reports them.
27 August 2026
Why We Sweeten with Honey Instead of Stevia
- 27 August 2026. Reference 3 was credited to Almasaudi. The record is by Albaridi, in the International Journal of Microbiology 2019. Corrected.
- 27 August 2026. “Enzymes and antimicrobial compounds that support your digestion and immune function” was cut back to antibacterial activity, which is all the cited review establishes.
- 27 August 2026. “Your gut contains trillions of bacteria, collectively weighing around 2 kilograms” was cited to the exact paper written to refute it. Sender, Fuchs and Milo put the number at about 38 trillion in a 70 kg adult, roughly the same order as the body's own 30 trillion human cells, and the total mass at about 0.2 kilograms. The sentence now says what the paper says, and names the 2 kilogram figure as the folklore it is.
- 27 August 2026. “Your gut lining is 70 percent collagen” was removed. The cited paper is a review of glycine metabolism and says nothing about the collagen content of the gut lining.
27 August 2026
Zinc, Testosterone and Whole Food Nutrition for Men
- 27 August 2026. Reference 2 linked a paper by Allouche-Fitoussi and Breitbart under Fallah's name. It now links Fallah's own record.
- 27 August 2026. “Every one of those steps requires zinc” was removed. The cited review is about male fertility and does not describe the steroid synthesis pathway step by step. The sentence now says what the review and the systematic review beside it support.
A guide not listed here has not had a correction published on it. That means nothing on it has needed one yet, which is not the same as a guarantee that nothing on it is wrong. If you find something, tell us and it will appear on this page. Back to the guides library.
