Carbon 60 (c60) + Valacyclovir
Valacyclovir brand name: Valtrex.
We found no known interaction between Carbon 60 (c60) and Valacyclovir 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.
Carbon 60 (c60) and Valacyclovir
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 Valacyclovir and Carbon 60 (c60) 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.
Worth understanding: our licensed dataset holds no drug-interaction record for Carbon 60 (c60) at all — not against Valacyclovir, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
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.

From our pharmacist’s overview on the Valacyclovir page
“Valacyclovir (Valtrex) works against herpes outbreaks only if enough of it gets absorbed into your blood, and most of this list threatens exactly that. Of the 27 supplements on file, 17 can change how well oral medicines like this one are absorbed, and the single major-rated entry, activated charcoal, binds drugs in the gut outright.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Carbon 60 (c60) is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Carbon 60 (c60) reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Carbon 60 (c60) and Valacyclovir records this page draws on were last updated June 22, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

Carbon 60 (C60) is a man-made molecule made of 60 carbon atoms, usually sold dissolved in oil and marketed as a powerful antioxidant or anti-aging supplement. Despite bold marketing, there is no good human evidence that it provides any of these benefits, and its long-term safety in people is unknown. Talk to your pharmacist or doctor before trying it, and avoid it during pregnancy and breastfeeding.

An interaction check asks whether these two react with each other — it does not ask whether Carbon 60 (c60) is a good idea for someone in your situation. Here is what our Carbon 60 (c60) record says about it on its own.
Carbon 60 (c60): dosing
There is no established or standardized dose for C60.

About Valacyclovir
What Is Valacyclovir Used For?
Brand name: Valtrex
Valacyclovir tablets are used in adults to treat cold sores (herpes labialis), genital herpes (initial and recurrent episodes), and shingles (herpes zoster). They can also be taken daily as suppressive therapy to reduce how often genital herpes outbreaks occur, and to lower the risk of passing genital herpes to a partner.
In children and adolescents, valacyclovir tablets are used to treat cold sores in those aged 12 and older, and chickenpox in those aged 2 to under 18. Valacyclovir has not been established as safe and effective for most uses in immunocompromised patients, with the exception of suppressive therapy for genital herpes in HIV-infected adults.
Most-Reported Side Effects for Valacyclovir
From FAERS, the FDA’s public side-effect reporting system (70,056 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.
