I found a way to quench my thirst for Rainbow Sherbet Liquid I.V. while keeping my wallet hydrated

Why I’m obsessed with this Rainbow Sherbet craze

My social media feed has been dominated by one thing lately: the vibrant, pastel-colored aesthetic of the Liquid I.V. Hydration Multiplier in the new Sugar-Free Rainbow Sherbet flavor. As someone who lives in Singapore, I often feel like I am missing out on these US-exclusive health-tech trends that go viral on TikTok. This flavor specifically promises the nostalgic taste of three-colored ice cream without the sugar crash, and I decided I simply could not wait for it to never arrive at my local pharmacy.

More about shipping to Singapore

I’ve tried the standard lemon-lime and strawberry flavors available locally, but they don’t quite hit that sweet spot of novelty and health. The sugar-free formula is a huge plus for my 2026 fitness goals, and the feedback from US users suggests it is the best-tasting variant they have released in years. Since I couldn't find a single shelf in Singapore stocking this, I knew I had to take matters into my own hands and shop US store sites directly.

My strategy for snagging US exclusives from Singapore

I’ve learned that the most cost-effective way to get my hands on these supplements is to bypass the resellers who charge triple the price. By using a freight forwarder, I can access the same prices that shoppers in California or New York enjoy. I usually head straight to the official Liquid I.V. website or major US retailers like Target to see the actual retail price, which is often around $25 USD for a 14-count pack—a far cry from the $60+ SGD I see on some local marketplaces.

When I shop, I always use my tax-free US address provided by my forwarding service. This little trick saves me about 7-10% in US sales tax immediately, which I then put toward my shipping costs. It makes the math much more attractive when I compare it to buying locally. If I’m ever unsure about the total cost, I quickly hop over to the shipping calculator to see if adding an extra bag of sticks makes sense for the weight.

Calculating the damage for my hydration haul

I know many of us worry about the cost of shipping powders across the ocean, so I did some digging into the logistics of this specific item. If you are planning to order a few packs, here is my estimate of what you are looking at for your shipment.

Since the weight is quite low, I find it’s much smarter to buy three or four pouches at once. This significantly lowers the price per item when looking at the international shipping rates. If I only bought one, the base shipping fee would make it expensive, but spreading that cost over four pouches makes it a total bargain compared to local prices.

When US stores play hard to get

I have run into a few hurdles in my shopping journey. Some US stores are notoriously picky and tend to block international credit cards or refuse to ship to any known parcel forwarding service. It’s incredibly frustrating to spend thirty minutes perfecting my cart only to have the order cancelled five minutes later. We’ve all been there, and it usually happens because the store's security system flags the non-US billing address.

This is where I started using the "BuyForMe" service. Instead of me struggling with my Singapore-issued card, I let the experts at comGateway handle the transaction using a US domestic card. They buy the items on my behalf, and because it’s a US card, the order goes through without a hitch. It is the safest way I’ve found to guarantee my Rainbow Sherbet doesn't get stuck in "order cancelled" limbo. It saves me the headache of contacting customer support or trying five different cards just to buy some hydration sticks.

Bringing the sherbet home to the Little Red Dot

Before I clicked "ship," I made sure to check the FAQ regarding health supplements. Singapore's customs are generally fine with personal quantities of health supplements, but I always keep my total order value (including shipping) below the current GST relief thresholds where applicable to keep costs down. Using a professional international shipping service ensures that all the paperwork is handled correctly so my package doesn't get held up at Changi.

I’ve found that the peace of mind of having a tracking number and a reliable partner to forward packages is worth every penny. My Rainbow Sherbet arrived at my doorstep in Singapore faster than some of my local deliveries! If you are sitting on the fence, I highly recommend checking the international shipping fees and seeing how much you can save by skipping the local markup. My wallet is happy, and I’m currently enjoying a cold glass of sherbet-flavored hydration while writing this.
