Our new Limited Edition Immunity flavor is GINGER LEMON, enriched with Vitamin C & Zinc, with zero sugar and no calories. It’s best enjoyed hot, but also works cold or sparkling.

Absolutely! Immunity drinks work hot, cold or sparkling. For a hot cup, we recommend water at 140F (60°C), because Vitamin C degrades with temperature. A cup in that range, enjoyed within 30 minutes, only loses about 10% of its Vitamin C, which is barely anything. Please don’t use boiling water, so you keep as much of the Vitamin C as possible.

All our cubes are gluten-free. As for vegan, there’s just one exception: GINGER LEMON isn’t vegan, as honey is used during its production, even though it doesn’t appear in the final ingredient list. All our other cubes are vegan.

Our vitamin and mineral content is tailored specifically for adults, so the Immunity flavor isn’t recommended for children under 12.
