Marine collagen supplements: Fillers


Collagen is the most abundant protein in the body, and it contributes to skin elasticity and hydration. Collagen makes up 70-80% of the dry weight of the skin and contributes to a youthful appearance. Unfortunately, as we age, collagen production declines by around 1-1.5% each year after the age of thirty. People may choose to take a dietary supplement to increase collagen levels and a popular choice is marine collagen. Marine collagen is a type I collagen and 80-90% of the collagen in your skin is also type I collagen.

Marine collagen is more homologous to human skin, making it a popular and very available supplement choice. However, choosing the right format of marine collagen is important in order to get the biggest benefit from your investment. In this article, we cover different formulations of marine collagen supplements on the market, the importance of choosing filler-free collagen supplements and how to choose a high-quality supplement.

Forms of marine collagen supplements

If you're looking to begin regular collagen supplementation, it’s important to choose a format that is going to work with your budget and lifestyle. Some formulas are more effective than others and each option has pros and cons, so it's important to educate yourself before choosing the best option for you.

Marine collagen capsules and pills

The cheapest and most common collagen peptide supplement option are pills and capsules. However, these tablets often contain bulking agents, fillers and binders which not only reduce the overall dosage of the supplement, but they can also reduce the efficacy of collagen absorption into the body, even if the tablet contains hydrolysed collagen.

Additionally, the convenience of swallowing tablets comes at a huge cost to dosage. One capsule may only contain a fraction of a gram of marine collagen. Combined with wasted filler space, marine collagen peptide tablets often aren’t worth your money.

Liquid marine collagen

You can also ingest marine collagen in liquid form. A collagen drink may contain fewer fillers since, the marine collagen and any other ingredients are dissolved in water. While liquid collagen may be easier to absorb than pills, they are bulky and heavy since liquid has already been added to the supplement; there may be a lower dosage as a result. Another downside is packaging; liquid supplements will need robust plastic or glass packaging for each daily portion which can be unsustainable or make the product even more cumbersome.

Marine collagen powder

Marine collagen protein powder is recommended as one of the best ways to ingest collagen. Powder supplements tend to be higher in purity and they also often come with higher doses of Marine collagen peptides. The collagen powder allows for more effective absorbance - hydrolysed powdered marine collagen can reach tissue within hours of consumption. Furthermore, marine collagen peptide powder can be easily dissolved in liquids such as cold drinks and smoothies. As a result of its soluble formula, there is no need for fillers and binders.

Why choose a collagen supplement without fillers?

When choosing a collagen supplement for daily use, it is recommended to avoid filler ingredients that may make supplements less effective. It is also recommended to avoid non-essential ingredients that may do more harm than good when consumed every day.

Choosing a hydrolysed marine collagen supplement

Hydrolysed marine collagen is a fish collagen that has been broken down into smaller, more digestible molecules. Hydrolysed collagen, or collagen peptides are popular in supplements because they are more bioavailable than the collagen proteins that you might find in bone broth, for example. Peptides are also easily dissolved, colourless and tasteless, making it the perfect ingredient for a collagen drink.

It's always important to bear ingredient quality in mind when buying health and beauty supplements. At Revive Active, we are transparent about our sourcing of marine collagen peptides - we use 'Peptan Marine' by the leading collagen producer Rousselot. Our use of Peptan collagen peptides in Beauty Complex, gives our consumers confidence in the quality of the product. Peptan® is also a type I collagen – the same type that is in our skin. This means the marine collagen peptides may be more bioavailable than other types of collagen.

Choosing a high-quality marine collagen supplement

When searching for the highest quality marine collagen supplement without fillers, there are certain elements you should consider. Firstly, to avoid fillers you will want a powdered form of supplement containing no fillers, binders or water which wastes space and may reduce the absorption of marine collagen and any other active ingredients. For a high-quality marine collagen supplement, make sure to look for ‘Peptan® Marine’ to ensure that your daily dose of marine collagen is sustainably sourced and of the highest quality and purity.

You may also want to check supplement dosage to ensure that your supplement does contain a high dose; a dose of 5000mg or above has been shown to be effective. Beauty complex includes a dosage of 7000mg.
