Rutin / Oxerutins (Hydroxyethylrutosides)
A flavonoid (rutin) whose semi-synthetic derivatives — hydroxyethylrutosides/oxerutins (Venoruton) — have meta-analysis evidence for modestly improving chronic venous insufficiency symptoms. Most evidence is for the rutoside derivative, not plain rutin.
What the evidence says
Most Rutin studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from medium-quality meta-analyses and randomised trials published 2006–2015 with a typical study size of 136 participants.

Rutin has an evidence score of 4.5/10 — emerging evidence based on 4 indexed studies, including 1 meta-analysis. A flavonoid (rutin) whose semi-synthetic derivatives — hydroxyethylrutosides/oxerutins (Venoruton) — have meta-analysis evidence for modestly improving chronic venous insufficiency symptoms. Most evidence is for the rutoside derivative, not plain rutin. Representative study: PMID 25630350.
The commonly studied dose of Rutin is Oxerutins (Venoruton) ~1000mg daily; plain rutin products vary widely. Individual needs vary — start at the lower end of the range and adjust based on how you respond.

Rutin is a flavonoid (quercetin-3-O-rutinoside) found in buckwheat, citrus, and other plants. Its venoactive use is best supported in the form of hydroxyethylrutosides (oxerutins / troxerutin; brand Venoruton) — semi-synthetic derivatives that improve capillary resistance and reduce venous edema. A meta-analysis of 15 trials found modest improvements in chronic-venous-insufficiency symptoms (swelling, aching, restless legs). The honest caveat: nearly all clinical evidence is for the rutoside DERIVATIVES, not plain dietary rutin, which is far less studied. Like other venoactives, it relieves symptoms and is an adjunct to compression therapy.
Rutosides strengthen capillary walls and reduce permeability, limiting fluid leakage.
Flavonoid antioxidant activity reduces oxidative/inflammatory venous-wall changes.

Minimum: 4 weeks
Optimal: 12 weeks
Cycling: Not required
Note: With food; pair with compression.
Dose-response data unavailable. The current published research for Rutin does not provide sufficient dose-specific outcome data to generate reliable dose-response curves.
Refer to the Dosage & Timing section above for recommended dose ranges based on available evidence.
Reduces lower-leg swelling.
Eases aching, heaviness, and restless legs.
Limited data — use only if advised.
Flavonoids may have mild antiplatelet activity — theoretical additive effect at high doses.
Tip: Take with food
Tip: Reduce dose
The best time to take Rutin is with meals. Take it with food. Taken with food; consistency over weeks for edema relief.
Rutin is generally well-tolerated and considered safe for most healthy adults at recommended doses. The most commonly reported side effects are mild GI upset, headache/flushing. Use caution if any of these apply to you: Pregnancy/breastfeeding (limited data); Allergy to rutin/flavonoids.
