FAQ.

Q: What is the difference between grape seed extract and red wine extract?

A: Both are rich in Oligomeric Proanthocyanidins (OPCs), but differ in source and composition focus:

Grape seed extract: Typically contains higher, more standardised OPCs, making it the most efficient source for obtaining high-concentration OPCs.

Red wine extract: Contains other polyphenols besides OPCs, such as resveratrol, resulting in a more complex composition. If you seek a clear, high-dose OPC supplement, grape seed extract is the more direct and economical choice.

Q: What is the recommended daily dosage?

A: Based on most studies, the common effective dosage range for health maintenance is 150mg to 300mg per day (calculated as 95% OPCs). Specific dosages should be determined according to your product positioning and targeted health areas.

A: Grape seed extract is highly safe at recommended dosages. Due to its potential mild anticoagulant effects, individuals taking anticoagulant medications (such as warfarin) should consult their physician before use.
