What Supplements Does Ben Greenfield Actually Take?
Ben Greenfield is one of the most referenced figures in performance and longevity supplementation, and a common search is simply: what does he actually take? While the specifics of any individual's protocol change over time and should be confirmed against their own current statements, Greenfield's publicly discussed approach follows a consistent and well-documented philosophy. This article breaks down that philosophy and shows how to build a comparable stack using Xtendlife products that fit each layer.
Note for the Xtendlife team: this article should only claim a direct product relationship with Ben Greenfield where one has been verified and approved. The copy below is written around his publicly discussed approach and maps Xtendlife products to each category, without asserting personal product use. Confirm before publishing.
Ben's supplementation philosophy
Greenfield's approach is protocol-driven and built around a few clear priorities: mitochondrial health, cognitive performance, longevity, and recovery. He tends to favour whole-food matrices over isolated synthetics where possible, on the logic that nutrients delivered alongside their natural cofactors are often better used by the body. He also consistently emphasises clinical dosing over label dressing, meaning he looks for ingredients present at amounts shown to do something in research, not just trace inclusions added so they can appear on a label. Those two principles, whole-food bias and clinical dosing, are a useful filter for anyone building a stack.
The cognitive layer
Cognitive performance is central to any high-output protocol, whether the demand is writing, podcasting, training, or complex decision-making. The ingredients with the most consistent evidence for cognitive support include phosphatidylserine, which supports neuronal membrane health, and bacopa monnieri, which has trial evidence for memory over longer periods of use. Xtendlife's dedicated brain support formula in this category is Think Sharp, designed to support memory, focus, and clear thinking as the brain ages. If you are assembling a cognitive layer, this is the slot it fills. Confirm the current ingredient panel against the live product page before relying on any specific component.
The energy and adaptogen layer
Sustained energy and stress resilience are the second pillar, and they are closely linked. Adaptogens help regulate the body's cortisol response, which matters during periods of high training volume or sustained work stress, when chronically elevated cortisol can undermine sleep, recovery, and mood. Xtendlife's option here is Serene Saffron, which combines saffron extract and ashwagandha with B-group vitamins to help regulate cortisol, support mood and sleep, and maintain steady energy. Framed simply, this is the layer that helps you manage stress load rather than just pushing through it, which is exactly the distinction a protocol-driven approach is trying to make.
The foundational layer
Underneath the targeted layers sits daily nutritional insurance. A comprehensive multivitamin covers the gaps that even a good whole-food diet can leave, particularly as nutrient density in food varies and individual needs rise with age and training load. Total Balance Men's Premium delivers 97 ingredients spanning vitamins, minerals, amino acids, and botanical extracts in a single formula, which makes it a strong foundation that reduces the need for multiple separate bottles. The foundation is unglamorous but it is what the targeted layers sit on top of.
What to look for in a supplement brand
Greenfield's publicly stated criteria double as a sensible checklist for anyone. He looks for in-house manufacturing and batch testing, GMP certification, transparent ingredient sourcing, a clean supply chain, and no proprietary blends that hide individual ingredient doses. That last point is worth dwelling on: a proprietary blend lets a brand list impressive-sounding ingredients without revealing how much of each is actually present, which makes it impossible to know whether a clinically relevant dose is in there. Applying these standards before you buy anything will quickly narrow the field.
How to build a stack like this
The structure is layered and deliberately simple. Start with the foundation (Total Balance), add a cognitive layer (Think Sharp), and add an energy and adaptogen layer (Serene Saffron). From there, you add optional targeted products based on your individual goals, whether that is joint support, gut health, or cardiovascular support. The principle is to build intentionally rather than accumulate bottles at random, and to add one layer at a time so you can actually tell what is working.
A note on copying anyone's stack
It is worth a word of caution about replicating any public figure's protocol exactly. What works for a full-time athlete training at high volume is not automatically right for someone with a desk job and three kids. Individual needs vary with age, activity level, diet, existing health conditions, and medications. Use a documented approach as a framework for the categories worth covering, foundation, cognition, energy, and recovery, then choose the products and doses that fit your own situation. The layered structure travels well from person to person; the exact products and amounts should not be copied blindly.
Frequently Asked Questions
Does Ben Greenfield use Xtendlife products?
We only reference product relationships that are verified and approved. Where that applies, the relevant Xtendlife products are Think Sharp for cognitive support, Serene Saffron for stress and energy, and Total Balance Men's Premium for foundational nutrition.
What does a performance supplement stack usually include?
A protocol of this style centres on foundational nutrition (such as Total Balance Men's Premium), cognitive support (such as Think Sharp), and adaptogen and energy support (such as Serene Saffron), with additional targeted additions based on training phase and individual goals.
What should you look for in a supplement?
Prioritise clinically dosed, third-party tested supplements with transparent ingredient sourcing. Favour whole-food matrices over synthetic isolates where possible, avoid proprietary blends that hide doses, and require GMP-certified manufacturing.
How long before a stack like this makes a difference?
It depends on the layer. Adaptogens and B vitamins can be felt within a couple of weeks, while cognitive and foundational benefits build over one to three months of consistent use. Consistency matters more than any single dose.
Can you take adaptogens and a multivitamin together?
Yes. Adaptogens such as those in Serene Saffron work on the stress response, while a foundational formula like Total Balance covers broad daily nutrition. They address different things and are commonly taken together. Space them with meals if you prefer, but there is no general conflict between them.
