Thirdzy Ambassador Program

Sleep Stonger. And Share.

Thirdzy's ambassador program is for coaches, athletes, and health professionals who talk about recovery because they know how important it is. Not just because they're paid to.

What We Make

The sleep support for people who train.

10g collagen protein for muscle and joint repair — so you wake up ready to train again, not sore.

Magnesium and natural calming amino acids — fuel nervous system recovery so you fall asleep easily and sleep deeply.

No melatonin. No sedatives. No grogginess.

Who Thirdzy Is For

Trains consistently. But doesn't wake up feeling the way they should.

Our customer trains four or five times a week — CrossFit, HYROX, functional fitness, running.

They've probably tried melatonin, didn't love it, and want something that actually addresses the problem.
