We all want to live well. And while there are vocal characters in the wellness industry who want to live forever, for the majority of us, we just want to live as healthily as possible in the time that we have, which is just one reason supplements have become so popular. But just as we should be analysing the contents of the food that we eat, so too should we be considering what goes into our supplements.

The supplement market is a huge business, according to Grand View Research, its estimated size was $4.79 billion (approx £3.51 billion) in 2024 and is projected to reach USD 9.65 billion (approx £7.06 billion) by 2033. But the market is awash with ultra-processed formulations and ingredients lists lacking the true recommended daily intake to give us enough of what we truly need. This is why supplement stacking has become such a huge trend. Instead of taking one single capsule, hoping for a one-and-done solution, it is a more intentional way of ticking the nutrition boxes when you have deficiencies. “Supplement stacking refers to the intentional combination of nutrients and compounds to achieve a specific physiological outcome, whether that is improving energy, cognition, recovery or long‑term health,” says Dr Nirusha Kumaran, GP and functional medicine expert.
Supplement stacking is a strategic way to give the body what it needs. But it has to be done right, from the combinations to the time of day in which they are taken. “The potential benefits are that you experience greater health improvements compared to taking single supplements,” Kevin Leivers, founder and chief pharmacist of The Naked Pharmacy, adds. “However, to be safe and effective, this approach needs to be managed in a controlled way, supported by expert pharmacists or qualified health practitioners.”
The right pairings will work together synergistically as a team to enhance the benefits of the nutrients with which they are paired – take vitamin D and K2, for example, or collagen and vitamin C. These ingredients work better when they are layered together. “Think of it less like adding ingredients to a recipe and more like assembling a team,” says nutritionist Tina Lond-Caulk. “Each member covers a gap the others have, and their combined performance exceeds the sum of their individual contributions.”
