Absolutely loved the Peach Hibiscus!

I am so happy with my purchase of the Hydrology Peach Hibiscus pastilles! The flavor is fantastic and they dissolve so easily. I tried a few other flavors in a Mixed Flavor Box before this and this one is my favorite. Definitely going to subscribe for more next month. You should try them!

Easy to order, tasted fine

Just ordered some Hydrology Detox pastilles. The website was super easy to use, found what I wanted quick. They arrived without issues. The flavor was alright, not amazing but definitely drinkable. Everything went smoothly, no complaints.

Good deal on Discovery Pack

I was looking for a good value to try these out. The Discovery Pack was 20% off, which made it a smart buy. Got free shipping too since my order was over the threshold. Felt like I got a solid deal for my money.

Decent product, slow shipping

I bought the Hydrology Immunity pastilles and they taste pretty good, not too artificial. I did feel a bit more energetic after a week. The website was easy enough to navigate. My only real complaint was the shipping; it took 7 days to reach me in California, which felt a bit long. Otherwise, a pretty positive experience overall.

Subscription saved me money

I got the Hydrology Immunity Boost on a monthly subscription. I usually buy similar products, so I was keen to see the value here. The 10% off for subscribing helped a lot. The pastilles arrived well-packaged, and the recurring order was seamless. I had a quick question about changing my next delivery date, and customer service responded in under an hour, which was impressive. The pastilles themselves are effective; I've felt a noticeable difference in my energy levels since I started taking them daily. So far, very happy with the quality and the convenience of the subscription plan.

Is there usually a big sale around Black Friday for these? Thinking about stocking up.

C Carly 2 weeks ago
Definitely. They always have some kind of deal for Black Friday/Cyber Monday. Worth waiting for if you can.

J June 2 weeks ago
Oh yeah, Black Friday is one of their big sale periods. You'll probably see discounts in the 15-25% range, sometimes with bundles or free shipping thrown in. Good time to buy.

Are these really that different from something like Liquid I.V.? Or is it mostly just a different form factor?

N Nick R. 2 weeks ago
I think the ingredients are a bit different, and it's less powdery since it's a pastille. Taste is also usually less intense.

A Anna 2 weeks ago
They're different, yeah. Hydrology uses a different blend of stuff and the pastille form is unique. Less sugar than some others too, if that's a concern. Liquid I.V. is more about quick rehydration, these feel more like a daily wellness thing to me.

How's the return process if I don't like the taste of a flavor? Is it a hassle?

A Anna G. 1 month ago
Nah, it's pretty straightforward. I returned an unopened box once and it was fine.

From what I remember, their return policy is pretty standard. As long as it's within their timeframe and usually unopened, it shouldn't be a problem. Check their site for specifics though.

What's the deal with their loyalty program? Is it actually worth joining or just points for tiny discounts?

R Rachel 3 weeks ago
It's decent. You earn points for purchases and stuff, and you can redeem them for discounts later. Not life-changing, but every bit helps.

S Sophie Brooks 3 weeks ago
I'm in it. You get points for purchases, referrals, even your birthday. The points add up and you can get some pretty good money off future orders, especially if you buy regularly. Worth signing up for sure.

Can I use one of those '15% off first order' codes even if I'm signing up for a monthly subscription?

N Neil Nguyen 1 month ago
I think so, yeah. I used a similar code when I started my subscription a few months back.

W Wendy Carter 1 month ago
Yeah, usually you can. Most of their promo codes work on subscriptions for your first order. It's a good way to try it out cheaper.
