Also, collagen peptides help older people who make less collagen. Look for collagen peptides from Gelita. I recommend Verisol, which can be purchased inexpensively from Costco's online option on occasional sales (it's how we do it). This will help skin, hemorrhoids, and varicose veins with useful Type 1 Collagen, which is lacking. For hemorrhoids and varicose veins, it is a higher ratio or Type III to Type 1, coupled with a higher protein amount instead of collagen, in one study I've read.
Also, ergothioneine is very helpful for maintaining the endothelial layer in our vessels. This is most available in foods from Oyster and Maiitake mushrooms, but some is in white and brown button mushrooms, as well. For a supplement, the DoubleWood L-Ergothioneine at $10 for 60 capsules is a steal off Amazon.
The Diosmin and such we use is Doctors Best in their Vein formula. We get that from Amazon.
These things make a big difference and my wife's varicose veins she had even before we were married have gotten much better.
