Neuro Recall Side Effects: What Each Ingredient Can Do and When to Stop
Quick answer
No study has tested Neuro Recall, so its side effects come from research on each ingredient. Stomach upset and loose stools are the most likely, from bacopa and magnesium oxide. Ginkgo can add to bleeding with blood thinners, berberine interacts with several medicines, and green tea extract is a rare cause of liver injury.
What side effects can Neuro Recall cause?
Neuro Recall has no side-effect data of its own, because no study has tested it. Everything below comes from research and fact sheets on each ingredient, mostly at doses that may differ from the capsule.
| Ingredient | Milder effects reported | Rare or serious | Source |
|---|---|---|---|
| Bacopa | Nausea, faster bowel movements, stomach upset | Long-term safety not studied | (Rejuvenation Res 2013, Aguiar and Borowski, Bacopa review) |
| Magnesium oxide, 250 mg | Diarrhea, sometimes nausea and cramps | Above 350 mg a day from supplements | (NIH ODS, Magnesium (health professional)) |
| Ginkgo | Dizziness, stomach upset, headache | Bleeding risk with blood thinners | (NCCIH, Ginkgo: Usefulness and Safety) |
| Green tea extract | Nausea, constipation, stomach discomfort, higher blood pressure | Liver injury | (NCCIH, Green Tea: Usefulness and Safety) |
| Berberine | Upset stomach, diarrhea, constipation | Interactions with several medicines | (Memorial Sloan Kettering, Berberine (About Herbs)) |
| Alpha lipoic acid | Nausea, vomiting, indigestion | Low blood sugar at high doses | (Memorial Sloan Kettering, Alpha-Lipoic Acid (About Herbs)) |
| Cinnamon bark | None listed in our sources | Cassia type holds coumarin, linked to liver effects | (NCCIH, Cinnamon: Usefulness and Safety) |
| Alpha-GPC | Few studies report any | No long-term safety studies | (Alzheimer's Drug Discovery Foundation, Alpha-GPC) |
| L-theanine | None reported | Not advised in pregnancy | (Memorial Sloan Kettering, L-Theanine (About Herbs)) |
| Chromium, 120 mcg | None linked to high intakes | Low blood sugar with diabetes drugs; rare kidney and liver reports | (NIH ODS, Chromium (health professional)) |
The sources we read raise no notable side effects for bilberry, lutein, zeaxanthin, B12 or folate at amounts like these. One folate point matters, though: high folate intake can hide a B12 shortage (NIH ODS, Folate (health professional)).
Which parts of the body can Neuro Recall affect?
Grouped by body area, the risks fall into seven places. Tap each one to see which ingredients are involved and why.
Bacopa, magnesium oxide, berberine, green tea, ALA
Stomach and bowel
The most likely trouble. Five ingredients list nausea, upset stomach, loose stools or constipation. Taking the capsules with a meal is a simple first step.
Ginkgo
Head and balance
NCCIH lists dizziness and headache among ginkgo's common side effects (NCCIH, Ginkgo: Usefulness and Safety). Stop if they do not settle.
Ginkgo
Bleeding
Ginkgo may cause or lengthen bleeding time and can add to NSAIDs and blood thinners (Memorial Sloan Kettering, Ginkgo (About Herbs)). Watch for unusual bruising.
Green tea extract, cassia cinnamon
Liver
Green tea extract is a well-established, rare cause of liver injury. Cassia cinnamon holds coumarin. Berberine, by contrast, is rated an unlikely cause.
Berberine, chromium, cinnamon, ALA
Blood sugar
Four ingredients may lower blood sugar. With insulin or diabetes pills, that could add up (NCCIH, Diabetes and Dietary Supplements).
Berberine, green tea, magnesium
Medicines
Berberine slows several liver enzymes that clear drugs. Green tea extract can inhibit the CYP3A4 enzyme (Memorial Sloan Kettering, Green Tea (About Herbs)). Magnesium can block absorption of some medicines.
Label warning
Pregnancy
The label says do not use if pregnant or nursing. Ginkgo, berberine, L-theanine and green tea's caffeine all carry pregnancy cautions too.

Can Neuro Recall hurt your liver?
It is possible but rare, and green tea extract is the reason. LiverTox gives green tea extract its top score, A, as a well-established cause of liver injury, with more than 100 reported cases (LiverTox (NIDDK), Green Tea).
- When cases appear
- Usually 1 to 6 months after starting
- How serious
- It can be severe; fatal liver failure has occurred
- Enzyme rises in one trial
- 6.7% of extract users against 0.7% of controls
- Who may be more prone
- 5 to 15% of Americans carry a gene variant linked to it
- EFSA concern level
- 800 mg of EGCG a day or more from supplements
- EGCG in Neuro Recall
- Not printed; at most about 317 mg even if the whole blend were green tea extract
The gene variant point is from NCCIH (NCCIH, Green Tea: Usefulness and Safety), and the 800 mg level from EFSA, whose experts could not name a safe dose (EFSA, Safety of green tea catechins (news)). The real EGCG amount is far below our ceiling, since nine other ingredients share the blend, but the injury is not clearly tied to dose.
Signs to stop and call a doctor the same day
- Dark urine, like tea or cola
- Yellow skin or yellowing of the whites of the eyes
- Pain in the upper belly that does not settle

Does Neuro Recall interact with medicines?
Yes, several of its ingredients can. The interactions work in several different ways, and knowing which way helps you ask your pharmacist the right question.
Adds to bleeding
Ginkgo with warfarin, antiplatelets or regular NSAIDs. The effects can stack.
Slows drug clearing
Berberine can lower CYP2D6, 2C9 and 3A4 activity and raise cyclosporine levels (Memorial Sloan Kettering, Berberine (About Herbs)).
Stacks on blood sugar
Berberine, chromium, cinnamon and ALA with insulin or sulfonylureas.
Blocks absorption
Magnesium can cut absorption of bisphosphonates and some antibiotics.
Works against treatment
ALA may work against chemotherapy and radiation as an antioxidant.
Heart and cholesterol drugs
Green tea extract may interact with nadolol and atorvastatin.
The full list by medicine type is on the who Neuro Recall is for page, and the bleeding question has its own post: ginkgo, bacopa and blood thinners.
What should you do if you get a side effect?
Stop first and sort out the refund later. These four steps keep you safe and keep your options open.
- 1
Stop the capsules
Do not take the next serving, and do not test a smaller one.
- 2
Call a doctor
The same day for liver signs or unusual bleeding. For severe pain or feeling very unwell, get urgent care.
- 3
Bring the bottle
Show the Supplement Facts panel and say the blend amounts are not printed.
- 4
Contact the order desk
Call +1 (302) 200-3480 with your order ID. The refund window is printed at checkout.
How returns and refunds work is on the Neuro Recall guarantee page.
Why are Neuro Recall side effects hard to predict?
Because the facts that would size the risk are not printed. The label names every ingredient but gives no amount for the ten that carry most of the risks above.
- Amount of each blend ingredient
- Not printed
- EGCG and caffeine content
- Not printed
- Coumarin content of the cinnamon
- Not printed; the cinnamon type is listed only as Cinnamomum spp.
- Study of the capsules themselves
- None found
- Label direction
- 2 capsules daily, "or as needed"
The FDA does not approve supplements before they are sold; makers are responsible for safety (FDA, FDA 101: Dietary Supplements). Take "or as needed" to mean 2 capsules at most each day, since a second serving pushes magnesium over its limit.
Neuro Recall side effects: common questions
What are the Neuro Recall side effects?
No study has tested the product, so side effects come from its ingredients. The most likely are stomach upset, loose stools, dizziness or headache; rarer risks are liver injury from green tea extract and bleeding with blood thinners from ginkgo.
Can Neuro Recall cause diarrhea?
It can. Each serving has 250 mg of magnesium oxide, a form often linked to diarrhea, and bacopa and berberine can also loosen stools.
Can the green tea extract in Neuro Recall hurt your liver?
It is rare but possible. LiverTox lists green tea extract as a well-established cause of liver injury, usually 1 to 6 months after starting; stop and call a doctor for dark urine or yellow skin or eyes.
Is Neuro Recall safe to take long term?
No one knows. The formula has not been studied, long-term human safety has not been tested for bacopa, and alpha-GPC has no large long-term safety studies. Bring it up at your regular check-ups.
What are berberine drug interactions?
Berberine can raise cyclosporine levels, slow liver enzymes that clear many drugs, and may affect some diabetes drugs. Ask a pharmacist before taking any product that contains it.
Can Neuro Recall cause headaches?
It might. Headache and dizziness are listed among ginkgo's common side effects; stop if they do not settle.
Can you take too much vitamin B12?
No upper limit is set for B12 because the risk of harm is low. The 240 mcg in Neuro Recall is high on paper but is not known to be harmful.
Can supplements cause memory loss?
Our sources do not link any ingredient in this formula to memory loss. Medicines and low B12 can cause memory problems, so tell your doctor about every product you take.
Does Neuro Recall interact with medications?
Yes, several ingredients can: ginkgo with blood thinners, berberine with drugs cleared by the liver, four ingredients with diabetes medicine, and magnesium with some antibiotics and bone drugs.
