That’s the endo trap, and a chicken breast doesn’t fix it on a flare day. OneFit® Clean Lean Protein gives you 25g in a drink, with no dairy, gluten or soy, for 125 calories.

On a flare day, food is the last thing you want, so it’s the first thing you drop. Protein goes with it, and your energy and strength follow.
Cutting dairy, gluten and red meat is what most women do to manage flares, and it leaves you eating the foods with the least protein and almost no creatine. Both are what your muscle runs on, so it’s the first thing that goes.
No cooking, no chewing, nothing that sets your gut off. Clean Lean Protein, creatine and a probiotic in water, built for the days eating isn’t happening.
A drink is a lower bar than a meal, not a replacement for one.
Every whey tub asks you to undo the diet you built to stay well. This one doesn’t, and it absorbs and gets used just as well as dairy, so nothing’s lost.
Protein, creatine, magnesium, a probiotic and 16 vitamins and minerals, at doses that actually do something, not a pinch of each so it can go on the label. Every amount is printed per serve, so you can check it before you trust it.
Fatigue is on the same symptom list as the pain, and every meal you skip on a bad day makes it worse. Clean Lean Protein gets 25g of protein and the B vitamins that fight tiredness into you when eating isn’t happening, so the flare doesn’t take the whole week with it.
No shake fixes endo, and we’re not going to pretend this one does. What it does is put protein in on the days that usually leave a gap, so the good days stop being spent recovering from the bad ones.

See all reviewsYes, by the measure that matters. DIAAS scores how much of a protein your body can absorb and use, and Clean Lean Protein scores 1.00, the same completeness benchmark applied to dairy protein.
It is also high in lysine, which is the amino acid that cereal-based diets most often run short on. That makes it a sensible pairing with the way most dairy-free eating is built.
Less than if you do. The evidence for creatine on strength and lean mass is evidence for creatine combined with resistance training. On its own, the trials found little.
The reason it is in this formula is different, and simpler: dietary creatine comes almost entirely from meat, so cutting meat out lowers your stores whether you train or not. Whether closing that gap is worth it to you depends largely on whether you lift.
It is the most common reason people abandon a protein, and a fair question to lead with. The Cacao in particular was formulated around that problem rather than around the ingredient list.
If the texture or flavour is not right for you, the flavour promise lets you swap within 24 hours, and the 90-day guarantee covers the rest.
Mostly by what else is in the serve. A plain protein gives you protein; this carries 5g of creatine, 250mg of magnesium, 1g of electrolytes and 16 vitamins and minerals alongside it, all printed per serve rather than folded into a blend.
If you already take a protein and a separate creatine and a multivitamin, this is those three in one drink. If you only want protein, buy a protein. We would rather say that than pretend otherwise.
25g of Clean Lean Protein and 5g of creatine monohydrate per 35g serve: one sachet or one scoop, shaken into 300ml of water. One serve daily, at whatever time you will actually remember it.
Whenever you’ll actually remember it, at the same time each day. Daily consistency matters more than perfect timing. A serve taken every day beats a better-timed one taken twice a week. Pick a time of day that is easiest to keep.
Anyone who wants one daily serve covering protein, creatine, electrolytes and micronutrients instead of managing several separate products, and anyone for whom eating enough on a given day is the hard part. It is not a weight-loss product, it is not a treatment for any condition, and it is not a replacement for meals.
It replaces the stack rather than adding to it. One sachet covers what most people were buying as separate tubs: 25g of protein, 5g of creatine, 1g of electrolytes and 16 vitamins and minerals, all in the same drink and all printed per serve.
No, and we are not going to imply otherwise. This is a food product covering the nutrition side. It does not treat, manage or relieve endometriosis or pain of any kind, there is no study behind this variant showing anything of the sort, and it is not a substitute for the medical care you are under.
What it is: 25g of protein in a form that goes down on a day a meal won’t, with every dose printed per serve. Questions about the condition itself belong with your doctor.
You’re covered by a 90-day full refund guarantee, and you can cancel or pause a subscription at any time. If it’s the flavour rather than the formula, the flavour promise lets you swap within 24 hours.
Per 35g serve: Clean Lean Protein isolate, micronised creatine monohydrate, L-carnitine tartrate, BCAA 2:1:1, magnesium citrate, potassium citrate, sodium chloride, Lactobacillus paracasei, plus 16 vitamins and minerals, natural flavouring and sweetener.
Dairy-free and gluten-free; lactose nil detected. No collagen and no other animal-derived protein. Not intended for children, or for anyone pregnant or nursing, without medical advice.
Third-party lab tested every batch, with results published. Made in Australia to premium ingredient standards. The formula is versioned and revised as evidence develops. The current supply is v4.7.
Doses are set at amounts intended to be meaningful rather than label-filling: 20 billion CFU of Lactobacillus paracasei, 25g protein, 5g creatine monohydrate and 1g of elemental electrolytes per serve.
Take one serve daily. Blend or shake one 35g sachet (or one scoop) into 300ml of water or a beverage of your choice, at the same time each day.

Per 35g serve (1 sachet or 1 scoop), Rich Cacao. 20 servings per package.
