Support Your Skin, Hair and Nails, and Keep Moving Easily, With One Ingredient
10g of grass fed collagen peptides a serve. 97% protein, 97 cents a serve, and the whole ingredient list is one item. Most people buy it for one reason and report three or four.
It is almost never one thing. Somebody starts on collagen for their skin and three months later mentions, almost in passing, that their nails have stopped splitting. Somebody starts for their nails and ends up talking about the stairs.
That pattern is the most consistent thing in our reviews, and it is not what collagen gets advertised on. Collagen gets advertised on one promise at a time, because one promise is easier to sell.
This is an ad, so weigh it accordingly. The reasons below are the ones people give in 387 published reviews, and the arithmetic at the end is arithmetic you can check yourself.

Our ingredients list is one item
Turn over whatever protein or collagen label you have in the pantry. Everything after the first entry is taking up room in the scoop that collagen is not. Ours is one line, and this is the whole of it.
Bovine collagen hydrolysate
10g per serve, 9.3g of it pure collagen peptides (protein)
Pure and unblended. No flavour, no sweetener, no filler, and no added vitamin C deciding your intake for you. Hydrolysed into small peptides, Type I and III, rich in glycine, proline and hydroxyproline. Grass fed and grass finished, Kosher certified, Australian owned and operated.

What people report
Ordered by how often it comes up in our reviews, not by how well it sells. These are reports from customers, not outcomes we promise.
Skin that looks and feels better. Type I and III collagen peptides supply glycine, proline and hydroxyproline, the amino acids the body uses to build its own collagen.
It tastes of nothing. Pre-hydrolysed peptides dissolve in seconds in hot or cold liquid, with no grit and no aftertaste. This is the reason people are still taking it in month three.
Hair with more body and less breakage. Most often reported between weeks eight and twelve.
Easier everyday movement. Collagen is the protein cartilage, tendons and ligaments are largely built from. A 10g serve is the dose people use when movement is part of why they are taking it, not the 3g to 6g a beauty brand doses.
Nails that stop splitting. Usually the first thing people mention, because you are looking at your hands all day.
Easy on the stomach. Pre-digested peptides ask very little of your digestion, which is why people who did not get on with whey or plant powders tend to get on with this.
97 cents a serve. One ingredient, 10g of it, at a price that makes a daily habit affordable for years rather than months.
How long until you notice a difference?
This is not an overnight fix, and it would be dishonest to pretend otherwise. It is a slow build. Knowing roughly when to expect what is what keeps people patient enough to stay with it.
0 - 30 days
It becomes part of the morning
10g dissolved into coffee or a cold drink, no grit, no taste. Nothing to notice yet, and that is normal. This stage is only about whether the habit sticks.
30 - 60 days
The first small things
Nails are usually first, because they are the easiest to see. Some people notice fine new hairs at the hairline and skin feeling more supple.
60 - 90 days
It starts to add up
Skin texture and hair condition are most often reported here. This is also where people describe moving through the day more easily. It is the window the published research uses.
90 days and beyond
You stop thinking about it
Most people stop noticing the collagen. It is simply part of the morning, and most report the baseline holds for as long as the daily 10g does.
Individual results vary. Always read the label and follow the directions for use. Talk to your healthcare professional before use, particularly if pregnant, nursing or taking medications.
The most reported change is the one you see in the mirror
Skin comes up more than any other single thing in our reviews. What people describe is rarely dramatic. It is texture. Smoother. Softer. Less papery on the backs of the hands. The word that comes up most is not “younger”, it is “better”.
Collagen is roughly a third of the protein in the body and a large share of what gives skin its firmness. Production slows from around 25 and keeps slowing. That is ordinary biology, not a condition.
Hydrolysed collagen supplies the amino acids the body uses to build its own, as part of a normal diet.
As you age, collagen production slows
Collagen is scaffolding. Skin, hair follicles, nail beds, cartilage, tendons and bone all depend on it, and from your forties the body replaces it more slowly than it loses it. That is a decades-long slope, not an event.
Which tells you what to expect. Published collagen research runs eight to twelve weeks of daily use before it measures anything. Anyone promising a fortnight is selling you a trial, not a result.
It also tells you what matters most, and it is not the brand on the pouch. It is whether you are still taking it in a year. Everything after this is about making that likely.
No beefy taste, and mixability makes the daily habit seamless
Taste and mixability are the second most mentioned thing in our reviews, ahead of hair, ahead of joints, ahead of nails. On a beauty product that sounds like a footnote. It is the whole game.
Reviewers use the word tasteless without being asked to. That is the most boring fact on this page and probably the most important one.
Unflavoured powder disappears into the coffee you were already making. No new routine, nothing to remember, nothing to tolerate. The supplement that works is the one you do not have to think about.
Being straight about the exception: in plain water, some people notice it. In coffee, tea, a smoothie or food, they do not.
There's 100s of options. Why Nutraviva Collagen?
01
Pre-hydrolysed peptides absorb faster than intact collagen
This collagen is broken down into small peptides before bottling, bypassing the digestive work your body would normally do. A 10g serving dissolves in seconds. Intact collagen molecules are too large to absorb efficiently. Hydrolysed peptides skip that bottleneck entirely.
02
The review record is unusually consistent
Scepticism about supplements is earned, because most do not deliver. This product has 387 published reviews at 4.9 stars, and the reports cluster in the same places: skin, mixability, hair, movement and nails. That is not marketing, it is the same four or five things said hundreds of different ways.

of reviewers gave five stars, 356 of 387
03
Grass fed and finished, both halves of the animal's life
Sourcing matters. Grass fed is a claim about most of an animal's life, grass fed and finished is a claim about the end of it too. Plenty of labels say the first and mean the second happened on grain. Ours says both, and the brief is simple: 100% pure bovine collagen hydrolysate, zero fillers, zero preservatives.
387
published verified reviews, averaging 4.9
04
Gentle enough that people who gave up on protein powders stay on this one
Many people arrive at collagen because whey protein, plant powders or whole-food supplements triggered bloating. Pre-hydrolysed peptides are already broken into absorbable pieces, so sensitive digestion handles them easily. One customer with haemochromatosis praised the simplicity, since there is no added vitamin C to complicate their condition.
05
For as little as $0.97 per serving
Supplements fail when they are inconvenient or feel expensive. One 800g pouch delivers exactly 80 individual 10 gram servings, so a single daily serve lasts nearly three months. At $77.90 that is under a dollar a day. Heat stable and tasteless, it dissolves in morning coffee or cold water without gelling.
What you are actually comparing

The questions that come up most
The same worries come up every time. Here are the honest answers.
Nails are usually first, around weeks four to eight. Skin and hair are most often reported between eight and twelve weeks. Published collagen research uses the same window. Individual results vary.
Nothing, in coffee, tea, smoothies or food. In plain water some people notice it. Reviewers use the word tasteless without being prompted.
Most people report more than one thing. In our reviews the most common combination is skin with hair and nails, and a good number mention everyday movement as well.
It is pre-hydrolysed, broken into small peptides before packing, so it dissolves in seconds and the body does less work to use it.
It contains no dairy, lactose, gluten or soy. Pre-digested peptides ask very little of your digestion, which is why people who did not get on with whey or plant powders tend to get on with this.
Because it decides your intake for you and takes up room in the scoop. If you want it, eat a kiwifruit.
100% pure unblended bovine collagen from grass fed and grass finished cattle. Kosher certified, glyphosate free, Bovaer and Rumin8 free. Australian owned and operated.
10g daily. Give it eight to twelve weeks before you decide anything. An 800g pouch is about 80 days, which is roughly one honest trial.
One ingredient, and most people report more than one thing
One ingredient, ten grams a serve, 97 cents a serve. Eight to twelve weeks before it is fair to judge.
