Marine Collagen Powder - Unflavoured 350g

Regular price $63.00 Sale

Kiwi Nutrition Marine Collagen is made from 100% pure Type 1 Hydrolysed Marine Collagen, which is clinically proven to provide support for skin appearance, hydration and elasticity, while also supporting strong and healthy hair and nails.

Our Marine Collagen is sustainably sourced from France and is a by-product of the fishing industry, utilising resources that would otherwise go to waste. Each 10g serving contains 9.95g of marine collagen, with 50mg of Vitamin C added to support collagen synthesis and provide anti-oxidant benefits to the rest of your body. The small size of our collagen peptides (2000 Daltons) ensures high bioavailability to maximise the benefits to your hair, skin, nails and joints.

We have samples of our collagen powder available here.

Dr Neil Van Geest founded Kiwi Nutrition in 2017 after finding it difficult to find affordable and natural nutritional products to support his mother during her battle with cancer. Kiwi Nutrition donates 10% of its profit to the NZ Cancer Society.

Comparison of NZ Marine Collagen Powders

Comparison NZ Marine Collagen Powder, NZ Marine Collagen Powder Revew, Kiwi Nutrition Marine Collagen Powder

There is a huge amount of influencer endorsement going on around collagen, but in fact there are very few manufacturers of Marine Collagen globally. We have put together this table to highlight the similarities between collagen products available in NZ and provide clarity to the consumer.

Collagen is a protein so the protein content of a product is a good guide to the collagen content, as long as there are not additional proteins on the ingredients list.

To keep things simple, we have compared products by analysing the price per gram of protein, rather than price per serving, as serving size varies between brands, from 4g with Jeuneora to 11g with Dose & Co. There is no good evidence for the variation in serving size between brands – the clinical studies that showed meaningful benefit from daily collagen used doses from 1g to 10g per day.

* For comparison purposes only. We do not sell a product without additional Vitamin C as Vitamin C is important in collagen synthesis and is also a potent antioxidant.

How much marine collagen do I need to take?

The clinical studies that have demonstrated the benefits of daily collagen used a wide variety of daily doses, ranging from 1g to 10g.

Individuals have different diets, different needs and different rates of absorption so we recommend using 10g initially until you notice improvement, and then reducing it to a maintenance dose where you retain the improvements. This may be somewhere between 1 and 5g per day.

How long do I need to take marine collagen for before I see results?

The clinical studies that demonstrated benefits from daily collagen generally lasted for 12 weeks but results will vary depending on the individual.

Benefits of marine collagen

Collagen makes up about 75% of our skin, providing a type of scaffolding that supports our skin’s structure. As we age, our body’s ability to produce collagen declines. From around our mid-twenties, production drops by around 1% per year, with a 30-50% total loss in women by post-menopause. Other factors like smoking, stress, unprotected exposure to sunlight and a poor diet can also cause a decrease in the amount of collagen our body produces.

Taking a high quality collagen supplement each day is an easy way to provide your body with collagen peptides and prevent the natural decline in collagen production from having an impact on the appearance of your skin, hair and nails.

The best marine collagen powder

Have been using this for the last 3 weeks and absolutely love it. It is really versatile and can be added to everything including smoothies without noticing any taste. I have also had it with a glass of water, there is a slight after taste but nothing to worry about. My nails are stringer and my skin looks better. Highly recommended.

Marine Collagen

I use it mainly by adding to my yoghurt but I have also just had it in a glass of water. I find it mixes really well. I am 50+ and noticed hormonal hair loss happening and this has really improved my hair condition and nails. I have had a lot of compliments on my skin texture as well. A really good product.

Enjoy this in my coffee in the morning, can't taste it. Hair is softer & my brittle nails are actually growing.
