the lineup.

six essentials. clean formulas, real ingredients, nothing extra.

a note from our co-founder

habits first.

I’m a physician, and my patients always asked me: “which supplements are actually worth it?” My answer is always the same: the foundation is healthy habits (how you eat, move, sleep and rest). Supplements are an extra. A plus.

The other reason was personal: most of the proteins I tried didn’t sit well with me or I simply didn’t enjoy them. I wanted something I’d actually look forward to taking.

So we made m+s the way I’d want it for my own family: combining science with my medical experience, with few ingredients, clear doses and flavors you’ll enjoy. Our goal is simple: to support you in building a better quality of life, alongside the routine you’re already creating.

That’s the plus in m+s: we’re not just supplements, we’re a lifestyle.

Good source of electrolytes, flavor not over the top

“The flavor is present, but it is not strong or over the top, which I like. The powder did not clump at all in my water and mixed thoroughly without much effort.”

Great flavor, my top protein powder right now

“The flavor i was offered was chocolate, and I was surprised how much I liked it; it almost has a malty taste…”

I Like the Types of Magnesium in This A Lot

“These are a little large but were easy to swallow for me. No adverse tastes, smells… Made in the USA.”

★★★★☆

Solid Creatine Blend with a Refreshing Twist

“The lemon-lime flavor is surprisingly light and not overly sweet or artificial, which I really appreciate. It mixes smoothly with water and doesn’t leave that gritty texture I’ve experienced with some other creatine powders.”

The best

“I’ve tried numerous chocolate protein powders, but none compare to this one! … the rich chocolate taste makes it feel like I’m indulging in a treat rather than just getting my protein fix.”
