To Speak Plainly,

Getting older has a funny way of clearing the air. You start asking better questions. You stop tolerating nonsense. And when something needs fixing, you don't wait around for permission. You handle it.

That's why we built Plainspeak. No inflated promises. No anxiety-provoking marketing. Just products that actually work for women who demand and deserve better.

The Fundamentals of Strength

Nothing in your body works in isolation. So we didn't build a supplement that works that way, either. Here's how every precision dosed nutrient in Strength Water helps support the many systems that keep you strong -- from muscle and joints to skin and bone -- in just one daily scoop.

Muscle Strength
Protein Creatine Monohydrate

Women lose ~3-8% of muscle mass per decade after early adulthood. Protein & Creatine Monohydrate help support lean muscle & muscle strength.*

Skin & Joints
Collagen Peptides

Women lose up to ~30% skin collagen in the first five years after menopause. Collagen Peptides help support connective tissue, joints, and skin.*

Bone Health
Calcium Vitamin D3

Women lose ~1–2% bone density per year during midlife, accelerating during menopause. Calcium & Vitamin D3 help maintain strong healthy bones.*

Collagen Peptides

Before there were influencers, discount codes in bios, or THE INTERNET, there were middle school girls. Spreading that Marilyn Manson rumor. 

Women are the most powerful word-of-mouth engine on the planet. Which is why we're spending our dollars on the growth channel we trust above all others: Women telling women what actually works. We’re banking on the belief that once you try Plainspeak, you’re going to want to tell your friends about it.

Expertly Advised + Clinically Proven

We work with Dr. Gillian Goddard to review and advise on our formulation, using only ingredients backed by research.

"My philosophy about vitamins and supplements mirrors my philosophy on clothes: I want fewer better things. That said, there is evidence that women can benefit from adding certain supplements to their routine – specifically protein, collagen, creatine, calcium, and vitamin D, all of which have been shown to support strength and long-term health.

Strength Water checks every box. It contains all the science-backed ingredients I look for in a supplement, with nothing extra – just the right elements at clinically recommended levels, combined into one simple daily habit that's easy to stick to."
