Meet Stack: Phi’s new approach to vitamins

The Drop: Phi introduced Stack, a new vitamin system that uses phase-release micropill technology to deliver essential nutrients exactly when your body can best absorb them.

The Details: A fresh take on vitamin delivery

Phi created Stack to solve the fundamental problems with traditional supplements: poor absorption, inconvenient dosing, and suboptimal ingredient combinations. Its solution? Time-released micropills housed in just two daily capsules — one for morning, one for night.

Stack’s patent-pending phase-release technology tackles bioavailability by releasing complementary nutrients together and separating competing ingredients to maximize the benefits of every nutrient. Both the Day Stack and the Night Stack release vitamins and minerals in two phases: the initial phase during hours 1-5 after taking and the secondary phase during hours 5-9 after ingestion.

The Day Stack features phased-release B vitamins that deliver sustained energy for eight hours instead of the typical 90-minute window, potentially reducing your reliance on caffeine. It also includes Magnesium L-threonate which is shown to support cognitive function.

The Night Stack delivers nutrients like Vitamin D3, Magnesium L-Threonate, and Calcium Citrate delivered during the first five hours. The secondary phase releases additional nutrients like Iron, Vitamin C, and B vitamins during hours 5-9, supporting your body’s natural recovery processes while you sleep.

Every component of Stack is 100% recyclable. Phi has also committed to a 2:1 Reclamation program, which means for every gram of medical-grade plastic produced, they fund the reclamation of two grams of ocean-bound plastic.

Where to buy

Stack is available now at $120 for a four-week supply (28 Day Capsules and 28 Night Capsules) at Phi’s website.
