The LabBuilt backward from the job.

Every Headstrong formula starts with one outcome. Then we build a lineup of ingredients that work together to deliver it, with every ingredient and every dose on the label.

How we formulate.

The same standards our athletes are held to, applied to what goes in the bottle.

01

Define the job

One outcome per formula: a daily cognitive boost, focus on demand, or overnight recovery. If an ingredient doesn't serve the job, it doesn't go in.

02

Build the lineup

Ingredients chosen to work together toward that outcome, at amounts consistent with the research behind them. No single ingredient is the star.

03

Show every dose

No proprietary blends. Every ingredient and every dose is printed on the label. If we won't tell you how much is in there, it shouldn't be in there.

04

Certify it

NSF Certified for Sport, so athletes competing under anti-doping rules never have to second-guess the batch.

2%

Your brain is about 2% of your body weight.

20%

It uses about 20% of your body's energy.

Performance starts in the brain.

That's true in the third period, in the fourth pitch of the day and in the exam room. Sports nutrition built for the body. Headstrong builds for the other half.

Raichle & Gusnard, PNAS, 2002

No single ingredient is the star.

Each formula is a lineup built around one job, and the benefit comes from how the ingredients work together. Here is every player and the role it plays. Doses are on every label.
