about Collagen Intensive
Behind every Glow25 product there is a philosophy, shared
by Sarah Jessica Parker too: ageing is not a
process to hide. It is what makes us who we are.
This is the pro-aging philosophy.
These proteins consist of amino acids that are linked together in chains of different lengths. Depending on the number of amino acids per molecule, they are classified differently:
Proteins: more than 100 amino acids
Polypeptides: more than 10 amino acids
Oligopeptides: fewer than 10 amino acids
Tripeptides: 3 amino acids
Dipeptides: 2 amino acids
This means that a tripeptide consists of exactly three amino acids linked together.
Tilapia. The fish are kept in aquaculture in Hainan, and these processes are certified under both FOS (Friend of the Sea) and BAP (Best Aquaculture Practices).
Collagen Original consists of 100 % pure bovine collagen hydrolysate, without any other additives. Collagen Intensive, on the other hand, also contains vitamin C, zinc and biotin and is made from fish collagen hydrolysate.
Another difference lies in the molecular size and dosage:
Collagen Original has a molecular size of 2000–4000 Da, which allows the body to absorb it over a longer period. The daily intake is 15 g; an overdose is not possible. The gut gradually releases the collagen building blocks into the blood.
Collagen Intensive has an even smaller molecular size of only 500 Da. This allows the body to absorb the 2,5 g daily dose very quickly. As it can reach the blood in a high concentration, the recommended amount should not be exceeded to avoid an overdose.
There are also differences in how they are used:
Collagen Original is particularly suitable for coffee, smoothies, shakes, tea or juices.
Collagen Intensive can also simply be taken in 300 – 400 ml of water.
The main difference lies in the collagen source:
Collagen Plus contains bovine collagen hydrolysate. Collagen Intensive, on the other hand, contains fish collagen hydrolysate. Both products contain vitamin C, zinc and biotin – in the same amounts.
Another difference is the molecular size and absorption:
Collagen Plus has a molecular size of 2000–4000 Da, so the body processes it over a longer period. The daily intake is 15 g, and the gut gradually releases the collagen building blocks into the blood.
Collagen Intensive has a particularly small molecular size of only 500 Da. This means that a large part of the 2,5 g daily dose can reach the blood very quickly.
Neither product should be overdosed, as they also contain vitamins and zinc. With Collagen Intensive, the particularly fast absorption of the collagen building blocks must also be taken into account.
There are also differences in how they are used:
Collagen Plus is particularly suitable for coffee, smoothies, shakes, tea or juices.
Collagen Intensive can also simply be taken in water.
Stir the contents of one stick (2.5 g) into your favourite drink or food and take one portion per day. Alternatively, you can simply dissolve Collagen Intensive in 400 ml of water and enjoy.
Like Collagen Plus, Collagen Intensive should not be used in boiling hot drinks (> 80°C).
You can dissolve Collagen Intensive in all cold and warm drinks – including water and, of course, your beloved Glow Coffee.
Yes, you can easily combine Collagen Intensive with the Collagen Capsules. We even recommend it, as the hyaluronic acid and pomegranate peel extract in the capsules complement Collagen Intensive perfectly.
Yes, Collagen Intensive was developed so that you can easily combine it with Collagen Original, Collagen Plus or Collagen Marine. However, we recommend spacing out the intake – for example, Collagen Original in the morning and Collagen Intensive in the afternoon.
Collagen Intensive can be a valuable addition to your daily collagen routine. However, if you combine it with Collagen Plus, you should skip the collagen capsules that day, as the vitamin C dose would otherwise be too high.
💡 Recommendation: Combine a maximum of two collagen products per day (Collagen Intensive, Collagen Plus or collagen capsules).
You can easily support your vitamin C levels with Collagen Plus or the Collagen Capsules.
Yes, you can support your zinc and biotin levels by combining it with Collagen Plus. However, make sure that your daily zinc intake does not exceed 5 mg.
If you have an appointment for a blood test or a laboratory test, please tell your doctor or the laboratory staff that you are taking biotin or have recently taken it.
We developed Collagen Intensive in sticks because the daily dose is only 2,5 g. Such a small amount is difficult to measure accurately with a scoop, so we opted for the practical stick format.
