Stack leverages decades of research to create a new, patent-pending phase-release approach that ensures each nutrient is delivered exactly when your body can use it best. This solves a major problem in supplementation: for instance, iron absorption can drop to just 8% if it’s not paired with vitamin C, so we release them together for maximum impact. We also separate competing ingredients like magnesium and calcium to prevent them from blocking one another’s benefits. Stack is unlike any other supplement—let us manage the timing so you can focus on living well.

Every ingredient in Stack meets rigorous standards for purity, safety, and consistency. While most supplements rely on ‘food-grade’ standards at around 80% purity, Stack uses 99%+ pharmaceutical-grade ingredients meeting the stringent criteria of advanced medical research. By applying the same technology trusted in cutting-edge medical applications, we deliver reliably potent nutrients in every micropill.

Every component of Stack is 100% recyclable. However, we acknowledge that not all products may be recycled by consumers. To safeguard against environmental impact, for every gram of medical-grade plastic we produce, we fund the reclamation of two grams of plastic that would otherwise enter our planet’s oceans. This proactive approach ensures that each purchase of Stack will remove twice the plastic from the environment as it introduces. We hope other companies that require the use of plastic will join us in our 2:1 Reclamation commitment.

We offer free shipping on every order, with no hidden fees. If Stack isn’t the right fit, just reach out within 30 days—we’ll make it right, no questions asked.
