The honest problem with most performance supplement routines isn't the quality of the individual products — it's the complexity. Protein here, creatine there, electrolytes after training, probiotics in the morning, multivitamin with breakfast, carnitine at some point. The timing gets confusing, the products pile up, and the whole system falls apart the moment life gets busy. The result: the person who is most consistent wins, and consistency is hardest to maintain when there are too many moving parts.
OneFit was built to solve this. It consolidates 7 categories of supplementation into one daily sachet — not by using token doses to hit the label, but by including each at clinically relevant amounts. 25g of hydrolysed protein (the most bioavailable protein form). 5g European creatine monohydrate — the exact dose supported by the strongest evidence base in sports science. 20 billion CFU probiotics (Lactobacillus paracasei). 1g quad-electrolytes covering sodium, potassium, magnesium, and chloride. 1g L-carnitine for fat oxidation and energy. 1g BCAAs. 16 vitamins and minerals including methylcobalamin B12, 5-MTHF folate, Vitamin D, E, C, and chromium.
Formulated in collaboration with UNSW. Manufactured in a TGA-approved Australian facility. Every batch independently tested for heavy metals, pathogens, allergens, creatine purity, and HASTA-screened for WADA prohibited substances. Available in Chocolate (700g pouch, 20-sachet box, or individual sachets) and Orange Pine (20-sachet box or individual sachets).

The ingredient selection in OneFit reflects what the research actually supports rather than what markets well. Each category has a reason for inclusion at its specific dose.
Hydrolysed protein is used rather than whey isolate or concentrate because it has been pre-broken down into smaller peptides — it absorbs faster and is more gut-friendly, particularly useful for people who experience bloating with conventional whey. 25g provides the leucine threshold needed to reliably trigger muscle protein synthesis.
5g creatine monohydrate is the dose used in the majority of published clinical trials showing performance, strength, and recovery benefits. European creatine monohydrate is specified because it is produced to pharmaceutical standards and free from the impurities (dicyandiamide, DHT) sometimes found in cheaper Chinese-sourced creatine.
20 billion CFU of L. paracasei is included because the gut-muscle connection is genuinely relevant in a performance context: a healthy gut microbiome improves protein absorption, reduces systemic inflammation from training, and supports immune function. L. paracasei specifically has research support for exercise-related immune resilience.
L-carnitine at 1g supports fat oxidation — the process by which the body accesses stored fat for energy. This is particularly relevant during fasted or low-carbohydrate training, and contributes to body composition alongside training.
The vitamins and minerals use activated forms where they matter: 5-MTHF folate bypasses the MTHFR conversion issue, methylcobalamin B12 is immediately usable, Vitamin D and E support immune and hormonal health. These are the same decisions made in premium standalone vitamin products — not cheap synthetic forms added as a secondary thought.

Add one sachet or scoop (35g) to 300–400ml of water and shake for 60 seconds. Drink after any exercise session — the combination of protein, creatine, electrolytes, and carnitine is most relevant in the post-training window. On rest days, take at any time that fits your routine. Consistency every day (including rest days) is what drives the creatine and probiotic benefits.
The sachets are convenient for travel, the gym, or the office — no measuring required. The 700g pouch with scoop is the most economical per-serve option and works well at home.
Tip from the brand: coconut water makes it extra tasty.

A strong fit if you:

• Currently take multiple supplements and want to simplify without compromising the stack
• Have tried building a supplement routine before and struggled to stay consistent with multiple products
• Train regularly — gym, sport, running, group fitness — and want daily performance and recovery support covered in one go
• Are subject to WADA substance testing and want a HASTA-screened product
• Want one high-quality daily habit rather than a complicated multi-step supplement protocol
  
• Are building a Perform routine and want an all-in-one foundation to build on

• Replaces protein powder, creatine, electrolytes, probiotics, BCAAs, L-carnitine, and a multivitamin in one serve
• 25g hydrolysed protein — fast-absorbing, gut-friendly, triggers muscle protein synthesis
• 5g European creatine monohydrate — pharmaceutical grade, clinically studied dose
• 20 billion CFU L. paracasei probiotics — gut health, protein absorption, immune resilience
• 1g quad-electrolytes — full hydration support (sodium, potassium, magnesium, chloride)
• 1g L-carnitine — fat oxidation and energy system support
• Activated vitamins (5-MTHF folate, methylcobalamin B12) — functional doses, not token amounts
