What’s in the Immunity Collection?

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.

Can I enjoy Immunity drinks hot, and how hot should the water be?

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.

Can I get early access to the Immunity Collection, and is shipping free?

Yes, for our Reward Members! Members get exclusive 24h early access before everyone else. On top of that, all Members enjoy free shipping with no minimum purchase from 22 to 25 October 2026. Not a Member yet? Joining takes just a minute and it’s free. SIGN UP.

Are the waterdrop® cubes vegan and/or gluten-free?

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.

Is the Immunity flavor suitable for children?

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

How hot do we like it?
How hot do we like it?

By hot, we mean Sunday-in-a-sauna hot, not Sahara-in-August hot.

By hot, we mean hot enough that you blow on it. Not so hot that you blow on it for twenty minutes and forget it exists.

By hot, we mean hot enough to fog up your glasses. Not hot enough to need a safety briefing.

By hot, we mean steamy, not scalding. Think slow-burn, not emergency room.
