SUPPLEMENTS WITH ANTIVIRAL ACTIVITY🧵
Some are finding benefit from fibrinolytic supplements like nattokinase which directly break down clots & biofilms. Once those clots degrade, however, pro-inflammatory molecules & viral debris may be released into circulation. ⬇️

This may cause temporary adverse effects — Herxheimer-like reactions — especially in those too ill or weak to clear out the debris.
Therefore, it may be helpful to take supplements with antiviral activity.⬇️

Note that those with Long Covid may have not only persistent SARS-CoV-2 infections but also additional reactivated viruses or bacteria, all of which must be targeted!
Among the most common reactivated viruses are EBV, VZV, HSV-1, HSV-6, & CMV.⬇️

Ideally, you would get tested for these viruses and if appropriate start prescription antivirals. But that isn’t feasible for everyone.
Antiviral supplements may help, so let’s highlight some of the most promising ones:
Curcumin
PEA + luteolin
Baicalein
Monolaurin
EGCG

I. CURCUMIN
Curcumin exhibits antiviral, anti- inflammatory, anticoagulant, antiplatelet, and cytoprotective activity.
This July 2022 in silico study found that curcumin inhibits the Omicron S protein and may also destabilize the ACE2-complex. pubmed.ncbi.nlm.nih.gov/35508082/

CURCUMIN
A 2020 study found that IL-1ß and IL-6 significantly decreased in acute COVID patients on nanocurcumin vs placebo. Other studies found that curcumin may interfere with other viral pathways as well.

CURCUMIN
An added bonus in #longcovid is that curcumin inhibits platelet aggregation. Studies suggest an association with LC & hyperactivated platelets.
Those on aspirin or fibrinolytic enzymes need to watch out for and sign of bleeding.

CURCUMIN DOSING
Depends on formulation
Generally, 500 mg to 2,000 mg daily
However, up to 8,000 mg daily x 18 months was tolerated with no reported toxicities in one population of pancreatic cancer patients. aacrjournals.org/clincancerres/…

CURCUMIN DOSING
Curcumin has poor bioavailability & water solubility. Take with a fatty meal and/or 2.5 - 10 mg piperine to increase absorption. Caution with drug interactions involving cyp3a4.
Notably, piperine also inhibits platelet aggregation.

CURCUMIN
Theracurmin is curcumin dispersed w/ colloidal submicron particles, the size of which are much smaller than conventional curcumin particles (0.19 µm vs 22.75 µm). Theracurmin is 20x more bioavailable than regular curcumin formulations; thus doses are ~30-60 mg.

Curcumin Cautions:
Avoid in gallbladder or liver disease. Curcumin could elevate liver enzymes. Since some pwLC may already have ⬆️ liver enzymes, this may be one supplement to limit for very short term use. If prone to kidney stones, get oxalate-free curcumin.

II. BAICALIN (aka huáng qín)
Baicalin, a flavonoid derived from skullcap, is the main metabolite of baicalein. It is purported to exert antiviral, antibacterial & antioxidant effects via multiple pathways. Studies suggest it also ⬇️ IgE & thus histamine. link.springer.com/article/10.100…

BAICALIN
This in vitro study found that baicalein & GCG--a catechin found in green tea--have high affinity for binding Mpro, the same enzyme target of Paxlovid. This inhibitory activity was potent, showing strikingly low IC50 values (~5-13 µM)! ncbi.nlm.nih.gov/pmc/articles/P…

Is 5-13 µM feasible in humans?
This study examined safety & PK of baicalein in healthy humans. Subjects took 200, 400, & 600 mg baicalein or placebo QD day 1 & 10 & TID days 4–9. Cmax at 600 mg was close to 2 µg/mL = 4.48 µM, suggesting 5 µM is feasible.

BAICALEIN DOSING
Is 600 mg a safe dose?
Authors investigated parameters including liver enzymes, urinalysis, SCr, TG, & CRP & concluded, “All drug‐related AEs were mild & resolved during the study w/o further treatment. The frequency of drug‐related AEs was not a/w ⬆️ dosage.”

In this single-dose study, authors observed that the exposure of baicalein began to plateau at 600 mg doses and speculated this was due to the saturation of baicalein absorption. Therefore, doses above 600 mg may not be useful. pubmed.ncbi.nlm.nih.gov/33753147/
BAICALEIN SAFETY
Despite authors finding no significant toxicities, proteinuria stood out to me (600 mg: 5 out of 10 w/ proteinuria). In those w CKD or reduced GFR, I would consult with a TCM expert before initiating baicalein supplements, or consider a reduced dose.

However, resveratrol's metabolites may elicit benefits as well & Vinia is above the 5 µM threshold. These metabolites (glucuronide & sulfate conjugates) have been found in much higher plasma concentrations than free resveratrol in humans, but their effects are not well-studied.
DOSING
-complicated in part due to HORMESIS
-Typical dosing range = 100 to 1,000 mg/day
-food or empty stomach okay
-must consider CYP drug interactions (3A4, 2C9, 2D6)
-2 g/day & up has been associated with an increase in adverse effects such as diarrhea, nausea, headache

🚨Due to biphasic hormetic dose-dependent effects of resveratrol (see above), I have hesitated to write about this supplement. I feel like it's very tricky to dose properly and comes with unknown risks. However, many have requested a review.

OTHER CAUTIONS WITH RESVERATROL:

-may affect thyroid: ⬆️ TSH in rat studies, but effects in humans not studied
-anti-platelet activity, so caution if on Plavix/aspirin

Overall, RESVERATROL appears to have great potential in many diseases including Long Covid.
However, dosing is tricky & further complicated by inter-individual variability. Drug interactions must also be considered. Furthermore, bioavailability varies significantly b/t brands.
