The OG elderberry brand, developed by a virologist and actually clinically studied as a finished product. Can reduce cold duration by 2-4 days. One of the few supplement brands where the specific formulation matters.
Sambucol is THE original elderberry brand with actual clinical studies on this specific product (Zakay-Rones 2004). The 3.8g extract (equivalent to 1.9g fresh elderberries) far exceeds the 600mg optimal threshold for elderberry extract. This is one of the rare cases where the brand itself is part of the evidence. Single-ingredient simplicity means you know exactly what you're getting.
