CogniHoney Official Website Side Effects & Safety
CogniHoney Side Effects and Safety: The Interactions Worth Knowing
CogniHoney is a dietary supplement for adults 18 and over, and most of its eleven names are familiar food and vitamin ingredients. The side effect reported in the bacopa trials was stomach upset. The interactions to know: ginkgo with blood thinners, green tea’s caffeine, and cinnamon with diabetes medicine.
Below: who it is for, each interaction, the timing question, reference limits, and when to stop.
Who CogniHoney is for, and the interactions to know first
CogniHoney is made for adults 18 and over. Read the caution printed on the bottle you receive before the first capsule. Three of the eleven names carry the interactions to know first: ginkgo, which may add to the bleeding risk of warfarin and other anticoagulants; green tea extract, which carries caffeine and has its own advice about food; and cinnamon, which lowered fasting glucose in trials, the same direction as diabetes medicine.
Side effects reported for the CogniHoney ingredients
Each note comes from research on one ingredient, not the finished capsule.
Stomach upset
The main side effect in a twelve-week bacopa trial in adults over 65 (Calabrese 2008). The full glass of water the directions ask for is the first thing to check.
Caffeine effects
Green tea contains caffeine (NCCIH green tea). It adds to whatever coffee, tea and energy drinks already fill the day.
Rare liver injury
Reported, rarely, with green tea extracts in capsule or tablet form; the USP review found case reports at 140 mg to about 1,000 mg EGCG a day (USP review).
Bleeding with blood thinners
Fifteen published case reports of bleeding while using ginkgo; thirteen of the people had other bleeding risk factors (Bent 2005).
Nerve symptoms from high B6
High intakes of vitamin B6 are linked to sensory neuropathy, which is why the adult upper limit is 100 mg a day (ODS B6).
Coumarin in cassia cinnamon
Coumarin, mainly from cassia cinnamon, has been linked to liver effects (NCCIH cinnamon); its daily limit is in the table below.
CogniHoney and medicines: who should check first
Nine groups with a reason to check first, each sourced.
| Who it concerns | What to know | Sources |
|---|---|---|
| Blood thinners and antiplatelet medicine | Ginkgo may increase the risk of bleeding in people taking anticoagulants such as warfarin. A review of fifteen case reports found a possible link; a meta-analysis of eighteen trials of standardised extract found no measurable change in clotting tests. Both are cited. | NCCIH's ginkgo fact sheet, Bent 2005, Kellermann 2011 |
| Diabetes medicine | Cinnamon lowered fasting glucose in trials of people with type 2 diabetes, and bilberry leaf has a traditional use for raised blood sugar. Together they point in the same direction as glucose-lowering medicine. | Allen 2013, NCCIH's bilberry fact sheet |
| Liver concerns | Liver injury has been reported, rarely, with green tea extracts in capsule form. EFSA found that, taken as food supplements, catechin doses at or above 800 mg a day may pose health concerns. The timing section below sets the USP food advice for green tea extract beside the CogniHoney direction. | the USP review of green tea extract and the liver, EFSA's assessment of green tea catechins, NCCIH's green tea fact sheet |
| Caffeine sensitivity | Green tea contains caffeine. The list does not say whether the extract is decaffeinated. The FDA cites 400 mg of caffeine a day as an amount not generally associated with negative effects for most adults. | NCCIH's green tea fact sheet, the FDA on how much caffeine is too much |
| Nadolol and atorvastatin | Green tea at high doses reduced blood levels of the beta-blocker nadolol, and green tea extract can reduce blood levels of atorvastatin. | NCCIH's green tea fact sheet |
| A history of stroke | A Korean cohort of about 12 million adults aged 50 and over linked prescribed alpha-GPC with a higher ten-year stroke risk. It is an association from health records, not proof of cause. | Lee 2021 |
| Metformin and acid-reducing medicine | Both lower vitamin B12 status over time. B12 is one of the eleven names, so anyone whose B12 is being checked or topped up should show the bottle at that appointment. | the NIH Office of Dietary Supplements fact sheet on vitamin B12, Aroda 2016 |
| Sodium limits | Himalayan pink salt is salt, mostly sodium chloride. Anyone on a low-sodium plan should count it, against a Daily Value for sodium of under 2,300 mg a day. | the FDA's guide to sodium in your diet, Fayet-Moore 2020 |
| Pregnancy, nursing and anyone under 18 | CogniHoney is made for adults 18 and over. Little is known about bilberry in amounts above those found in food during pregnancy or breastfeeding. | NCCIH's bilberry fact sheet |
Supplements can raise, lower or change the effect of a medicine, which is why the prescriber needs the full list (NCCIH).
The CogniHoney timing and the green tea caution, side by side
One ingredient carries its own advice about food; here it is beside the label direction.
| Source | What it says | What it applies to |
|---|---|---|
| The CogniHoney label directions | “Two capsules daily with a full glass of water, about 30 to 60 minutes before the largest meal.” | The whole CogniHoney serving, word for word on every page of this website. |
| The USP review | “Do not take on an empty stomach. Take with food.” Bolus doses taken while fasting raise catechin levels. | Green tea extract, one of the eleven names. |
| EFSA | Taken as food supplements, catechin doses at or above 800 mg a day may pose health concerns. | Green tea catechins. The 50% on the list is a standardisation figure, not a catechin dose. |
Sources: the USP review of green tea extract and EFSA on green tea catechins. The two directions differ. For most buyers the label direction is the one to follow; anyone with a liver condition, or on medicine processed by the liver, should show both to the prescriber before the first capsule.
Reference limits for the CogniHoney names
Four of the eleven names, and two things they carry, have published daily limits.
| Ingredient | Reference limit | Why it exists | Source |
|---|---|---|---|
| Vitamin B6 | 100 mg a day, adults | Sensory neuropathy at high intakes | ODS B6 |
| Choline | 3,500 mg a day, adults | Low blood pressure and fishy body odour | ODS choline |
| Caffeine | 400 mg a day, most adults | Not generally linked to negative effects | FDA |
| Green tea catechins | 800 mg a day or more | May pose health concerns as supplements | EFSA |
| Sodium | Under 2,300 mg a day | The Daily Value | FDA sodium |
| Coumarin | 0.1 mg per kg of body weight | Tolerable daily intake | Abraham 2010 |
For context, and for anyone taking another supplement with the same ingredients.
When to stop CogniHoney and get advice
Any of these is a reason to stop taking CogniHoney and speak to a doctor or pharmacist, bringing the bottle so they can read the label. The two names to watch are the blood-thinning botanical and the concentrated green tea extract.
Stopping early is covered by the guarantee. Within 60 days of purchase, call order support on +1 (302) 200-3480 with the order ID; return postage is yours, and the guarantee page sets out the route.
For anything urgent, call emergency services; the order line handles tracking, changes and refunds only.
Stop and get advice if you notice
- Unusual bruising, nosebleeds or bleeding gums, especially on a blood thinner.
- Yellowing of the skin or eyes, dark urine, or pain under the right ribs.
- Stomach upset that does not settle within a few days.
- Shakiness or sweating on diabetes medicine, which can mean low blood sugar.
- Jitteriness or poor sleep that began with the capsules.
CogniHoney safety questions
Can I take CogniHoney with warfarin or another blood thinner?
Ask the prescriber first. Ginkgo may increase the risk of bleeding with anticoagulants such as warfarin (NCCIH). A review of fifteen case reports found a possible link (Bent 2005), while a meta-analysis of eighteen trials of standardised extract found no measurable change in clotting tests (Kellermann 2011). Let the prescriber weigh that, bottle in hand.
Is CogniHoney safe with metformin?
Two things are worth raising with your doctor. Cinnamon lowered fasting glucose in trials of people with type 2 diabetes (Allen 2013), which points the same way as metformin. And long-term metformin use lowers vitamin B12 status (Aroda 2016); B12 is one of the eleven names on the CogniHoney list, so bring the bottle to the appointment where your B12 is checked.
Can I take CogniHoney while pregnant or breastfeeding?
CogniHoney is made for adults 18 and over, and little is known about bilberry above food amounts during pregnancy or breastfeeding (NCCIH). Speak to your doctor or midwife before taking it.
How this CogniHoney safety page is written
Four things a sceptical reader can check in ten minutes:
- Each fact names its source. The capsule count and the three claims are printed on the bottle front. The eleven names come from the CogniHoney ingredient list and the product photographs, and the serving from the label directions. Prices and the guarantee are CogniHoney’s own terms, as listed on 21 September 2026.
- Research amounts live in a column of their own, headed “What published research used”, beside a column that says what the list gives. No sentence here moves a number from the first into the second.
- Every study is cited against its own population. A trial in older adults, or in people with a diagnosis, is described as exactly that.
- Corrections change the date. Write to contact@Cogniqhoney.com and the review date moves forward.
We earn when you buy. Cogniqhoney is the USA Authorized CogniHoney Retailer named at the top of this page and this website makes money on orders placed through it. That is why the safety notes, the three-star review and the plain statement that CogniHoney is not a treatment for anything are on the page: they are where our interest and yours pull apart. Order support on +1 (302) 200-3480 handles tracking, changes and refunds and is never a way to place an order.
