What’s in the Immunity Collection?

Our Limited Edition Immunity Collection features three flavours made for winter: GINGER LEMON, CRANBERRY ACEROLA and SPICED PLUM. Each one is enriched with Vitamin C & Zinc, with zero sugar and no calories. They’re best enjoyed hot, but also work 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 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 Collection suitable for children?

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

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 'running into your ex at the supermarket' hot. Not scalding. Just unmistakably doing well.
