- Sea buckthorn berries, their oil, or flavonoid-rich extracts of the fruit have lowered biochemical indicators of increased cardiovascular risk in some, though not all, preliminary and double-blind human studies.
Dose:10 mg three times daily of a flavonoid extract of sea buckthorn for six weeksSea buckthorn berries, their oil, or flavonoid-rich extracts of the fruit have lowered biochemical indicators of increased cardiovascular risk in some,9,10,11 though not all,12,13preliminary and double-blind human studies. In a preliminary trial, people with heart disease who took 10 mg three times daily of a flavonoid extract of sea buckthorn for six weeks had less chest pain, lower blood cholesterol, and improved heart function.10 Double-blind research is needed to confirm these findings.
- Hemp protein may prevent cardiovascular disease by lowering cholesterol levels and through antioxidant activity.
Dose:Refer to label instructions
Researchers have found that small amino acid chains found in hydrolyzed hemp protein can act as antioxidants, and suggested that these same amino acid fragments are likely formed during normal digestion of hemp protein.14 These antioxidants could protect blood vessels and cell membranes from the free radical damage linked to cardiovascular disease progression.
In animal research, hemp seed meal was found to increase antioxidant activity and reduce cholesterol absorption in the digestive tract.15 Whether hemp protein has antioxidant and cholesterol lowering effects in humans is not yet known.
- Pea protein might help prevent cardiovascular disease by lowering cholesterol and triglyceride levels.
Dose:Refer to label instructionsA pea protein supplement lowered cholesterol and triglyceride levels more than casein protein in rats.16 Whether pea protein has the same effect in humans is not yet known.
