How I save $40 every time I order Thorne Magnesium Bisglycinate from the US to NZ

Why everyone in New Zealand is talking about Thorne

I have been part of the local biohacking community for a while now, and if there is one brand that constantly pops up, it is Thorne. Specifically, their Magnesium Bisglycinate powder has become the gold standard for anyone looking to improve sleep or recovery. Unlike the cheap magnesium oxides we often see on supermarket shelves in Auckland or Christchurch, this bisglycinate formula is highly absorbable and doesn't cause the digestive issues I used to experience.

Buy It For Me

Just a moment, securing your connection...

The problem we face here in New Zealand is availability. While a few niche wellness boutiques stock it, the prices are often astronomical. I noticed that my favorite powder was frequently out of stock locally, or marked up by nearly 40% compared to the US retail price. This led me to look into how I could get it directly from the source in 2026.

The price difference I found between NZ and US stores

I did the math before placing my last order. In a local NZ health shop, a single tub of Thorne Magnesium Bisglycinate was retailing for about $115 NZD. When I looked at US-based stores, the price was $48 USD, which is roughly $78 NZD at current exchange rates. Even with shipping, the gap was too large to ignore.

By purchasing three tubs at once, I managed to bring my per-unit cost down significantly. I used comGateway as my freight forwarder to handle the transition from the US to my doorstep. Even after adding the international shipping fees, I was still saving about $40 per tub compared to buying locally. For a supplement I take every single night, those savings add up over a year.

Shipping logistics for Thorne Magnesium Bisglycinate

If you are planning to follow my lead, you need to know what to expect regarding the package size. Thorne's powder tubs are relatively light, but they do take up some space in a shipping box. Here is a breakdown of what I found for my recent shipment.

I always recommend using a shipping calculator to estimate shipping cost before you hit the checkout button. It helps to avoid any surprises when the package arrives at the warehouse.

A quick note on volumetric weight

Since this supplement comes in a plastic tub, it doesn't weigh much, but the box it comes in can be slightly larger than the product itself. Most international shipping service providers will charge based on whichever is higher: the actual weight or the volumetric weight. Because Thorne tubs are sturdy and not overly bulky, they usually fall under the actual weight category, which is great for our wallets.

My experience using a freight forwarder for supplements

The process was much simpler than I expected. I signed up for a tax-free US address through comGateway, which allowed me to avoid US sales tax at the point of purchase. I then ordered my supplements from a US retailer and had them sent to that address.

If you have never done this before, I suggest looking at their how it works section. It is a very clear step-by-step guide that explains how your package moves from the US warehouse to New Zealand. I found the tracking updates to be very helpful, especially as the package crossed the Pacific. I also checked the FAQ when I had a question about how long they could hold my items if I wanted to wait for another order to arrive and consolidate them.

Importing supplements into New Zealand in 2026

We have to be careful with New Zealand Customs and Medsafe regulations. As of 2026, you are generally allowed to import a three-month supply of supplements for personal use. Magnesium bisglycinate is perfectly legal and doesn't require a prescription, so I had no issues with my shipment being cleared.

Just remember that in 2026, GST is often collected on low-value imported goods. Some shop us store platforms might include this at checkout, or your freight forwarder might provide options for handling it. I made sure my total order stayed within reasonable limits to ensure a smooth transition through Auckland customs. The effort of setting up a tax-free US address and managing the shipment myself was well worth the $120 total savings on my three-month supply.
