Why KEEP works
Target formula; final Supplement Facts before launch.
Eating less shouldn't mean getting less.
Smaller appetite, same needs
When you're eating less, whether by choice, by plan or because your appetite has changed, it's hard to fit enough protein into fewer, smaller meals.
Muscle matters more with age
After 50, keeping muscle takes real effort. Protein and strength work help support muscle as part of a healthy lifestyle.*
Too many tubs and pills
A protein tub, a greens powder and a handful of vitamins adds up in cost, clutter and effort. Most people don't keep it up.
How KEEP works
Whey peptides
Whey protein broken down with enzymes into smaller peptides using a US-patented process, licensed from our German manufacturer. Provides all 20 amino acids to help support muscle.*
One scoop
Mix one scoop of powder with water or milk. Easy to finish, even when you're not very hungry.
75+ nutrients
Vitamins, minerals and phytonutrients in the same serving, to help fill nutrition gaps when meals get smaller.*
What's inside
One scoop of powder brings together 30 g of complete protein per serving and a 75+ nutrient concept.
Complete protein
30 g complete protein per serving (target formula). Whey-derived amino acids plus peptide protein, with all 20 amino acids.

Target formula · pending manufacturer
Backed by research
We're building KEEP around ingredients with published human studies behind them, starting with two that are well studied for helping preserve muscle as we age.*
HMB
HMB (beta-hydroxy-beta-methylbutyrate) is made naturally in the body from the amino acid leucine. In a controlled study of healthy older adults, 3 g a day of HMB helped preserve lean muscle during 10 days of bed rest.*
Creatine monohydrate
One of the most researched supplements there is. In adults over 50, creatine taken alongside resistance training supports gains in lean mass and strength.*
Leucine-rich protein
Leucine is the amino acid that signals muscle to build. Research reviews on older adults point to leucine and protein, paired with strength training, as helping support muscle mass.*
Keeping muscle while losing weight
For anyone focused on keeping muscle while losing weight, or staying strong after 50. Pair it with regular strength work.*
