Fast&Up vs Cosmix vs OZiva: which plant protein fits your routine? After reviewing all three individually, we compared their exact formulas, serving sizes, sweeteners and buying costs. The most useful choice depends on whether you want a chocolate shake, prefer a particular ingredient list, or need an unflavoured powder for meals.
Quick recommendation: shortlist Fast&Up for a sucralose-sweetened chocolate shake, Cosmix if you prefer its monk-fruit-sweetened cacao formula, and OZiva for an unflavoured option. The comparison focuses on published nutrition, ingredients and cost per serving.

Figures come from product labels and manufacturer information. Unavailable values are not zero. The Cosmix product here is the standard pea-and-rice formula, not No-Nonsense Pro or Fermented Yeast Protein.
2. Which supplies more protein?
OZiva has the highest stated protein per serving among these versions. That does not establish that it will produce better muscle gains or that its protein is better absorbed.
Fast&Up’s reviewed serving works out to approximately 70% protein by powder weight, compared with approximately 63% for Cosmix. OZiva’s exact scoop weight needs confirmation before comparing protein concentration. A larger serving can change the headline protein figure, so compare measured portions and your dietary requirement.
BCAA amounts should not be added to total protein: those amino acids are already part of it. The NIH’s guidance on exercise supplements explains that adequate dietary protein supports muscle maintenance and repair, while supplements can help fill a shortfall. A powder alone does not replace appropriate training or a balanced diet.
3. Ingredients and sweetness: the practical differences
Fast&Up: chocolate with sucralose
The reviewed formula contains cocoa and a sweetener, with enzymes and probiotics also listed. Its online ingredient list and the supplied pack label have some differences, so the actual pouch matters. “No added sugar” does not mean unsweetened or zero total sugars.

Cosmix: cacao with monk fruit and a herb blend
The standard formula lists coconut milk powder, cacao and cocoa, vanilla, monk fruit, cumin, fennel, fenugreek and ginger alongside its protein isolates. This may appeal if you prefer that combination. It does not prove superior safety, taste or digestion compared with a different sweetener or formulation.

OZiva: an unflavoured option for flexible use
OZiva is the unflavoured choice in this comparison. Our assessment is that this makes it the most relevant starting point for someone who wants to try a powder in savoury meals rather than a chocolate drink. Unflavoured does not guarantee tastelessness: begin with a small recipe batch and judge the result yourself.

4. Which offers better value?
Discounts, sellers and pack variants change. Use each product’s final checkout price and compare an equal amount of protein.
Cost per 25 g protein = pack price ÷ estimated total protein in the pack × 25.
| Product | Estimated protein in the compared 1 kg pack | Cost per 25 g if each pack hypothetically cost ₹2,000 |
|---|---|---|
| Fast&Up | About 702 g: 27 servings × 26 g | About ₹71 |
| Cosmix | About 632 g: 1,000 ÷ 38 × 24 | About ₹79 |
| OZiva | About 810 g: 27 servings × 30 g | About ₹62 |
This is an equal-price arithmetic example, not a live price table. The totals are estimates from the stated serving information, which can include rounding. Substitute the price and nutrition on your chosen pack. Cost per gram cannot tell you whether you will enjoy or tolerate the powder.
5. Which is better for digestion?
Digestive tolerance is individual. Fast&Up’s enzymes and probiotics and Cosmix’s herb blend are ingredient differences, not evidence from a direct comparison proving fewer symptoms. OZiva’s plain flavour also cannot guarantee tolerance.
Check allergens and cross-contact warnings, follow the label and consider a small pack first. Persistent symptoms should be assessed rather than managed by repeatedly switching supplements based on advertising. If a medical condition affects your protein intake, discuss the choice with your clinician or dietitian.
6. How should you compare testing claims?
Our Fast&Up review links to an Informed Choice listing and a batch-report lookup. Cosmix describes third-party heavy-metal and microbiological testing. Our OZiva review does not verify a report for the buyer’s specific batch. This is a difference in the evidence collected for our articles—not a finding that one product is unsafe or untested.
Before relying on a certificate, match the product, flavour and batch, then check the tests, dates and results. A certification badge is not a guarantee of health benefits or freedom from every possible contaminant.
7. Our choice for different buyers
- For an unflavoured powder to try in meals: start by comparing OZiva’s label and price with your needs.
- For a chocolate shake with sucralose: shortlist Fast&Up, provided its formula suits your preferences.
- For a cacao shake with monk fruit: shortlist the standard Cosmix formula and check its cost per equal amount of protein.
- For the lowest ongoing cost: calculate with current prices before choosing.
- For a sensitive stomach: there is no established winner here; individual tolerance matters.
Frequently asked questions
Is 30 g protein automatically better than 24 g?
It is more protein per stated serving, but it is not a universal quality score. Consider serving size, overall intake, ingredients and price.
Are all three unsweetened?
No. The reviewed Fast&Up and Cosmix formulas contain sweetening ingredients. OZiva is the unflavoured version; check its complete current label rather than equating flavour and sugar claims.
Can I compare another flavour using this table?
Only after checking its label. Different flavours and product lines may change the serving size, protein and other ingredients.
Final verdict
The useful distinction is how you plan to use the powder. OZiva is our first shortlist for an unflavoured meal ingredient; Fast&Up and Cosmix are the two flavoured shake options, with different sweeteners and supporting ingredients. Check current value, try a manageable pack size and choose a formula you can use consistently. We would not pay extra solely for an unverified promise of better digestion or faster results.
