[Nutrition, "health foods"]

Also if you're like me and have #MCAS as a fun immune system problem

You probably know a lot of folks try Quercetin supplements to help with MCAS/allergies/inflammation

Spoilers: Quercetin has antioxidant effects

(And: again, it's not a magic cure)

Quercetin und Antihistaminika ermöglichen mir ein Leben ohne LongCovid Einschränkungen. Keine Brainfog, kein PEM und nahezu normale körperliche Belastbarkeit. Meine Frau verträgt Quercetin leider nicht und Mastzellenstabilisatoren wollte ihr bisher kein Arzt verschreiben.

Masked + sanitizer, Covixyl spray, Nosin nasal sanitizer, & various protocol supplements (NAC, quercetin, etc).

String beans are a top tier vegetable. And not only are they delicious, they have antioxidants that reduce illness/cell damage, including vitamin C, flavonols, quercetin, and kaemfero.

doctor: how about quercetin?
me: I'm on 500mg qid already 😬

my illness is a sitcom

Quercetin hat mir geholfen inzwischen quasi symptomfrei zu sein. Damit lässt sich meine Mastzellaktivierung in Kombination mit Antihistaminika sehr gut kontrollieren. Ich nehme es seit mehreren Wochen und es hat keine Nebenwirkungen.

Daily reminder to be so skeptical of AI search summaries, esp re: medical stuff!!

Googling #quercetin, AI says it “can also help with headaches & upset stomach.”

If you click the link whence it’s pulling that info, the source actually says quercetin may CAUSE headaches & upset stomach.

Trying Quercetin and Bromelain supplement capsules and they're working really well. Apparently I'm allergic to something and it was fucking w my vocal chords. They're natural antihistamines. Might re-record some vocals on the song I'm recording rn.

And Elizabeth Blackwell might be right too. The quercetin in apple peel, a natural antioxidant, helps to produce serotonin and dopamine, the hormones for cheering the spirits.

The idea that quercetin also fights cancer, though, is as mythical as King Arthur on his apple island.

Quercetin also works as a MC stabilizer but I'm one of the unfortunates who gets horrible heartburn from it, alas

Would LC + mass spec be overkill to quantify levels of quercetin molecules in different wines? @seamus.bsky.social , ready for a new project?

I’m quite certain, btw, that we’d find elevated quercetin levels in scotch (particularly Islay) as well. Bourbon, otoh, is completely fine for me.
For those of us who have been suffering with red wine headaches for years and years, this study offers potential validation.

We all knew it wasn’t the sulfites!

Now I just need a study confirming that Merlot grapes are absolutely laced with quercetin glucuronide…

While some early mouse studies show promise for a dasatinib and quercetin longevity cocktail, evidence doesn't yet suggest humans can benefit
September 16, 2026 at 10:07 AM
Aber mit diesem Maus Model könnte man jetzt testen was hilft... Rapamycin, Lithium, Taurin, Dasatinib, LDN, Quercetin etc... etc... Let's Go...
Echt heftig, aber trotzdem ein Lichtblick

Fuji apples contain
Quercetin, a key antioxidant. It enhances immune function and supports heart health. Eating these apples can protect cells from damage and slow down the aging process.
Also, the antioxidants contribute to healthier skin by guarding against environmental damage.

🧅 Onion Facts You Might Not Know!

✅ Onions contain quercetin, an antioxidant that helps protect cells from oxidative stress.

✅ The outer layers usually contain more antioxidants, so avoid over-peeling.

💚 Enjoy onions raw or cooked as part of a balanced diet.

Why does red wine trigger headaches for some people?

Chemists say the answer may lie in quercetin, a natural compound in grape skins that can interfere with alcohol metabolism and spike acetaldehyde levels.

Kapern enthalten Quercetin. Quercetin ist ein MastZell-Stabilisator. Darüber hinaus enthalten Kapern Kaemferol. Kaemferol ist ein SRC-Kinase Inhibitor. SRC-Inhibitoren (Dasatinib) plus Quercetin werden derzeit als Therapieoption getestet
