Grape Seed Extract 100 mg by Thorne

If your blood pressure runs high-normal or elevated, grape seed extract is one of the few botanicals with data for small reductions within 4 to 8 weeks. It also fits adults with leg heaviness or easy bruising linked to fragile capillaries, and those watching inflammation markers like hs-CRP (a general inflammation signal) or LDL oxidation. If you already eat lots of deeply colored fruits, the increment is smaller; if your diet is light on polyphenols, the effect is more noticeable.

Grape seed extract concentrates oligomeric proanthocyanidins (the antioxidant compounds in grape seeds) that protect LDL from oxidation and improve endothelial function, meaning your arteries relax more easily. They increase nitric oxide (the signal that tells blood vessels to widen) and help reinforce collagen in capillaries, which is why bruising and leg swelling can improve. These polyphenols also produce modest drops in hs-CRP in some users, aligning with reduced oxidative stress rather than acting like a pain-reliever.

Thorne’s capsule is 100 mg. Most clinical trials use 150 to 300 mg daily, so one capsule two to three times per day matches that range. Take with a meal to limit stomach upset and improve uptake. Split dosing, morning and evening, keeps levels steadier. Expect blood pressure and leg comfort changes in 4 to 8 weeks and inflammation marker shifts like hs-CRP in 8 to 12 weeks. If nothing changes by three months, re-check your dose and labs or reconsider the fit.

Skip or clear this with your clinician if you use blood thinners such as warfarin, apixaban, rivaroxaban, or antiplatelets like aspirin or clopidogrel, because polyphenols can have mild blood-thinning effects. Combine cautiously with blood pressure medicines to avoid additive drops. Stop 1 to 2 weeks before surgery. Avoid if you have a grape allergy. Safety data in pregnancy or breastfeeding is limited, so use only with clinician guidance. Monitor home blood pressure and review hs-CRP or lipid labs to track response.
