Antioxidant & Anti-inflammatory Effects: Hawthorn berries contain flavonoids, proanthocyanidins and other polyphenols that act as antioxidants, which may help neutralize free radicals and reduce oxidative stress. Healthline+2My WordPress+2
Cardiovascular Support (Heart & Circulation): There is some evidence that hawthorn (especially in extract form) may help improve blood flow, support heart function, and modestly help manage blood pressure or lipid levels (e.g. lower "bad" cholesterol / LDL).
Digestive Aid: Because a whole-fruit powder retains fiber and pectin, hawthorn may support digestion — possibly helping with digestion, regularity, or gut health. 
Potential for Lipid / Cholesterol Support: Some studies (and traditional use) suggest hawthorn may help improve cholesterol profiles (lowering LDL, triglycerides). 
Mild Relaxation / Well-Being Effects (less studied): Some sources claim hawthorn may help with stress, mild anxiety, or support general vitality — though evidence is much weaker and often anecdotal.
