The essentials

A closer look.

Natural Factors Grape Seed Extract delivers a concentrated source of oligomeric proanthocyanidins (OPCs), the polyphenolic compounds derived from Vitis vinifera seeds. It supports antioxidant activity and may help maintain healthy circulation and connective tissue integrity. A practical option for adults seeking plant-based antioxidant support.

Why It's Worth Considering: Natural Factors standardizes their grape seed extract for OPC content, providing consistent potency across servings, a meaningful distinction from non-standardized whole-grape preparations.

More category questions

How should I store this supplement?

Store in a cool, dry place away from direct sunlight. Most supplements are stable at room temperature (59-77°F). Keep the bottle sealed between uses. Check the label for any specific storage requirements — some probiotics and oils require refrigeration.

Can I take this with other supplements?

Most supplements can be taken together safely. However, some minerals compete for absorption (zinc and iron, calcium and magnesium) and should be taken at different times of day. If you're taking prescription medications, consult your healthcare provider about potential interactions.

How long should I take this supplement?

Most supplements benefit from consistent daily use over 2-3 months to achieve full effect. Some (like vitamins and minerals) can be taken indefinitely as part of a daily routine. Others (like specific herbs) may benefit from cycling. Follow the product's recommended protocol or consult a practitioner.

When is the best time to take this?

Fat-soluble supplements (vitamins A, D, E, K, omega-3, CoQ10) should be taken with a meal containing fat. Water-soluble supplements (B vitamins, vitamin C) can be taken anytime. Minerals are generally best absorbed with food. Probiotics should be taken with or just before a meal. Check the product label for specific timing recommendations.

How do I know if this supplement is working?

Track your specific health goals — energy levels, sleep quality, joint comfort, digestion, mood, etc. Most supplements take 2-8 weeks for noticeable effects. For objective measurement, baseline lab tests before starting (and repeat at 3 months) provide definitive evidence. The Gabriel Score incorporates clinical evidence for expected outcomes.
