Ask ten people at the gym how much protein they need and you’ll get ten confident answers — most of them wrong in one of two directions. Half are eating far less than they think, quietly undercutting months of training. The other half are choking down 200 grams a day because a video told them to, paying for protein their body simply excretes. The truth sits in a narrow, well-researched band, and once you know your own number, the entire “which protein, and when” question gets a great deal simpler.
That’s where a brand like Puravida earns its place. Born in Brazil to make a clean, organic lifestyle easier to actually practice, Puravida has become one of the country’s most trusted names in supplementation — and its protein line is a good example of why. Whey isolate, grass-fed whey, concentrate, plant-based protein, even a protein-rich vegetable soup: enough range to hit your number whatever your body and diet demand, all held to a single clean-label standard. This guide covers the number first, then how to fill it without wasting money.

The Number Most People Get Wrong
Start with the figure everyone quotes and almost everyone misreads: 0.8 grams of protein per kilogram of bodyweight per day. That number — printed on nutrition labels the world over — is the RDA, and the RDA is a floor, not a target. It is the minimum to keep a sedentary adult out of deficiency, not the amount that builds muscle, preserves it as you age, or keeps you full through the afternoon.
If you train, the research points somewhere very different. The weight of the evidence lands around 1.6 to 2.2 grams per kilogram per day for anyone lifting or trying to add muscle — roughly double the RDA. Put concretely:
- Sedentary, general health — about 0.8–1.0 g/kg; enough to get by, rarely enough to thrive
- Active and training — 1.6–2.2 g/kg; the range where strength and body-composition gains actually show up
- Over 40, or in a fat-loss phase — lean toward the top of the range; protein protects muscle precisely when age or a calorie deficit is trying to take it
For an 80 kg person who trains, that is roughly 130 to 175 grams a day — a figure most people badly underestimate until they write it down. Rather than guess, Puravida’s site has a protein calculator that turns your weight and goal into a real daily target in seconds. Get that number first; everything below is just how you reach it.

Whey or Vegan — Which Protein Actually Fits You?

Once you know the target, the shaker does the boring work of closing the gap between what you ate and what you needed. This is where Puravida’s range matters, because “protein powder” is not one product:
- Whey Protein Isolado — around 90% protein with minimal lactose; the fast-absorbing, lean choice for around training. Flavors run from Dark Chocolate to the cult Língua de Gato collaboration with Kopenhagen, and reviewers consistently note it mixes clean rather than chalky
- Whey Protein Grassfed — the premium tier, sourced from grass-fed milk for buyers who care where their whey comes from
- Whey Protein Concentrado — 70–80% protein at a friendlier price; a sensible everyday option when lactose isn’t an issue
- Vegan Protein (Proteína Vegana) — a plant-based blend with a complete amino profile, in Vanilla and Neutro, for anyone lactose-sensitive, plant-based by choice, or who simply wants variety
Whey or vegan — how to actually choose?
Simple rule: if you digest dairy comfortably and want the fastest absorption per real spent, whey isolate is the default. If dairy leaves you bloated, or you’re plant-based, Puravida’s vegan line is one of the rare ones that doesn’t taste like a penalty. Plenty of customers keep both — whey around workouts, vegan protein for everyday shakes — and there’s no rule against it. The best protein is the one you’ll actually drink every day.

Does Timing Actually Matter?

Here’s the myth worth killing: the “anabolic window” — the belief that if you don’t slam a shake within 30 minutes of your last rep, the workout is wasted. It is one of the most repeated ideas in fitness and one of the least supported. The current evidence says the window is measured in hours, not minutes; as long as you get adequate protein across the day, whether the shake lands at minute 20 or minute 90 barely moves the needle.
What actually matters is two things, and neither involves a stopwatch. First, the daily total — hit your grams and you’ve done about 90% of the job. Second, distribution — spreading protein across three or four meals of roughly 25–40 grams each supports muscle protein synthesis better than backloading it all at dinner. So the practical takeaway is a freeing one: you don’t need to sprint to the locker room. You need a protein source convenient enough to hit your number every day — which is exactly why a good powder, and Puravida’s single-serve sachês for the gym bag, beats an elaborate plan you abandon by Wednesday.
How to Read a Protein Label Without Getting Fooled
Two numbers decide whether a protein is worth buying, and the marketing on the front of the pot is neither. Flip it over. First, protein per serving against serving size — an “isolate” should be delivering the high-90s percentage that name implies, not padding the scoop with fillers. Second, and quieter, is the trust question: what is actually in there? Brazil’s supplement boom brought a real counterfeiting problem with it, and it’s common to hear gym-goers say they avoided supplementing for years out of fear of adulterated whey. Puravida built its reputation on the opposite — a clean-label philosophy and products that nutritionists recommend by name, the kind you can buy, in customers’ own words, sem medo (without fear). When the entire value of a protein is what’s inside the pot, that is not a soft benefit. It is the whole point.
Protein Beyond the Shaker
Powder is a tool, not the whole toolbox — and leaning on it for every gram is how shakes start to feel like a chore. The fastest way to hit a higher target is to raise the protein floor of the food you already eat, then let the shaker cover whatever’s left. It helps here that Puravida isn’t only powders: the same clean-label standard extends into functional foods, including a genuinely useful Sopa de Legumes Vegana (vegetable protein soup) for the days a shake doesn’t appeal. A high-protein breakfast, a protein-forward lunch, and one shake will get most people to a number that three desperate scoops at night never will.
How to Buy Smart (and Actually Save)
Protein is a recurring cost — you finish a pot and buy another, month after month — and Puravida’s store is clearly built to reward exactly that predictability:
- Assinatura (subscription) — schedule recurring deliveries, take a discount on every subscribed product, free shipping on orders above R$150, and cashback, with the freedom to cancel anytime
- Loyalty program — earn points on purchases and subscriptions, redeemable for cashback and exclusive items
- Seasonal promotions — whey isolate and the bestsellers regularly appear with meaningful discounts around major retail dates
Protein is the ideal subscription product precisely because your demand is so predictable: you know almost to the day when the pot runs out. Automating it at a discount is the rare case where the lazy option and the smart option are the same one.

Final Thoughts
Protein isn’t complicated once you strip away the noise. Find your real number — closer to 1.6–2.2 g/kg than the label’s 0.8 if you train — hit it consistently across the day, and stop worrying about the stopwatch. The only decision left is where your protein comes from, and that’s the easy part: a certified, clean-label source you can trust, in whey or plant-based, at a price that rewards you for staying consistent. Start by calculating your target, pick the protein you’ll genuinely enjoy drinking, and let the habit do the rest.
