No. They won't help.
The people boast that they have been strengthening their blood vessels with routine for a long time, quercetin, Detralex and other bioflavonoid rubbish. The veins are hiding there and everything. Under this case, a hat-hating fantasy on the topic aspirin and related bleeding. Like bioflavonoid lovers won't have anything like that. This is a misconception.
First, dear comrades, the beneficial effect of bioflavonoids on blood vessels is similar to the effect of aspirin itself. That is, bioflavonoids reduce platelet activity. Inactive platelets do not clump together or clog blood vessels, and therefore are less likely to have a stroke or heart attack. This is the same Mediterranean diet: vegetables, fruits, wine, everything.
Secondly, the vessels do not become stronger because of this. What? Yes! Veins and any other vessels from all kinds of bioflavonoids and vitamins can be slightly strengthened from the outside due to the skeleton of muscles and connective tissue. This will make the vessels stronger. Well, kind of like a metal braid around a flexible hose in your kitchen faucet.
Ever looked under the sink? There, a flexible hose from a rubber hose, which is protected from the outside with a metal mesh, is suitable for the mixer.
Now imagine that your blood vessels are likewise fortified with bioflavonoids from all kinds of plants, vegetables and fruits (including wine), but this is only a mesh outside the vessel.
And inside the vessel, happy, sluggish and inactive platelets float, which do not bother at all with the quality of the inner wall of the vessels. They do not feed this wall, they plug holes in it. But on the other hand, they don't make blood clots either.
If the platelets are inactive, then the vascular wall can leak due to internal ruptures. It's like that flexible eyeliner in your kitchen. From the inside, its rubber ages, gets dirty with scale and breaks. Outside, this case is held in place by a metal mesh. But the metal mesh won't stop the leak. It is only needed to protect the outside from damage to the liner by a stool or desk drawer.
It turns out that even if quercetins with rutins strengthen your blood vessels from the outside, they will in no way hold back the rupture of the inner wall due to a lack of active platelets. Worst of all, these bioflavonoids themselves render platelets inactive. That is, they themselves can provoke bleeding.
Therefore, professional adherents of alternative approaches to the treatment of blood vessels tell us what? They say that bioflavonoids should not be combined with bleeding medications. Because it could be worse. That's it, brothers! You cannot protect your blood vessels with quercetin from aspirin.
