Alpha-gpc + Cefaclor
Cefaclor brand names: Ceclor CD, Ceclor.
We found no known interaction between Alpha-gpc and Cefaclor in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Cefaclor states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Alpha-gpc and Cefaclor
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Cefaclor and Alpha-gpc in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.
Alpha-gpc safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Cefaclor
Interactions in our licensed database are recorded against drug classes, not just single drug names. Cefaclor is filed under 6 classifications — including organic anion transporter 3 (oat3) substrates, organic anion transporter 1 (oat1) substrates, antibiotic drugs. Alpha-gpc has documented interactions with 1 drug class — the most serious being scopolamine (transderm scop) (minor) — and none of Cefaclor’s classifications are among them.
Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.
Alpha-gpc Does Interact With Other Medications
Alpha-gpc has 16 minor known drug interactions in our database — Cefaclor isn’t one of them. If you take anything else, check it against the full list below.

Some Cefaclor Products Have a Food Rule — Alpha-gpc Should Not Break It
At least one FDA label for a product containing Cefaclor says to take it with food. If you take Alpha-gpc on an empty stomach out of habit, keep them separate — and take Cefaclor with a meal where the label says to.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Cefaclor products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.
DOSAGE AND ADMINISTRATION The absorption of cefaclor extended-release tablets is enhanced when it is administered with food.
From the Dosage and Administration section of the FDA label we read for Cefaclor — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›
A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.
See Every Supplement That Interacts With Cefaclor
This page covers Alpha-gpc only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Cefaclor page lists 60 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), Asarabacca (major), Siberian Cocklebur (major), African Wild Potato (moderate) and Aristolochia (moderate).
By severity: 3 major · 46 moderate · 11 minor.
From our pharmacist’s overview on the Cefaclor page
“The entries worth understanding before any others on this cefaclor (Ceclor) page are the kidney risks and charcoal. Cefaclor is a cephalosporin antibiotic, typically a short course for ear, sinus, throat, or skin infections, and two herbs here, Siberian cocklebur and asarabacca, can damage the kidneys on their own, so pairing either wi…”

About Alpha-gpc
What is Alpha-gpc?
- Memory and learning support
- Age-related cognitive decline
- Alzheimer's disease and dementia (under study)
- Athletic and physical performance
- Source of choline
Alpha-GPC is a choline-containing compound used mainly for memory, brain health, and as a choline source. There is some evidence it may help cognition in people with dementia, but evidence in healthy people is limited. Talk to your pharmacist or doctor before starting it, especially if you take other medicines or have a health condition.
Synthesized compound; also found naturally in soy lecithin and small amounts in foods · Capsules, tablets, powder, liquid
An interaction check asks whether these two react with each other — it does not ask whether Alpha-gpc is a good idea for someone in your situation. Here is what our Alpha-gpc record says about it on its own.
Alpha-gpc: dosing
There is no official, standardized dose of Alpha-GPC for any condition. Doses used in research have varied depending on the purpose and the people studied.The safest approach is to follow the directions on the product label and not exceed them.

About Cefaclor
What Is Cefaclor Used For?
Brand names: Ceclor CD, Ceclor
Cefaclor treats a range of bacterial infections. Cefaclor capsules and oral suspension are used for ear infections (otitis media), lower respiratory tract infections including pneumonia, strep throat and tonsillitis, urinary tract infections (including kidney infections and bladder infections), and skin and skin structure infections.
Cefaclor extended-release tablets are approved for a narrower set of uses in adults: acute bacterial flare-ups of chronic bronchitis, strep throat and tonsillitis, and uncomplicated skin and skin structure infections. Not all formulations are approved for the same conditions, so the form matters.

Cefaclor Is Linked to Lower Levels of 7 Nutrients
Natural Medicines records Cefaclor as a medicine that can lower these. This is not an interaction with Alpha-gpc — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
