Collagen Powder | How to Read Collagen Labels - Bare Biology

Some brands of marine collagen powder may be made from factory-farmed fish, or fish caught in a way that harms the environment. Look for this information on the label. If a brand is proud of the provenance of its product, it will shout about it. 

With competitive price and timely delivery, SEMNL sincerely hope to be your supplier and partner.

Many supplement brands don’t even name the kind of fish they’ve used, so you’ve no idea what you’re taking. It’s worth trying to find out. Farmed fish are exposed to growth hormones and antibiotics, while non-farmed larger fish are more likely to harbour toxins.

Bare Biology’s fish collagen powder is sustainably produced from wild-caught, non-GMO cod. Small, wild cod are an excellent source of marine collagen because the skins are low in sodium and they naturally contain fewer contaminants.

The same meticulous care went into sourcing the cow hides used for our bovine collagen. We source from grass-fed cattle raised on Swiss and EU farms under the highest animal welfare standards. These herds graze freely on fresh grass during the summer and are fed hay during the winter months. Strict EU standards ensure that the cattle are raised without antibiotics, hormones, GMOs, veterinary drugs, or unnecessary treatments. Happy cows, healthy collagen.

A collagen product with flavourings may seem appealing to your taste buds, while the use of additives like bulking agents and fillers will certainly make a product cheaper. But it also means you won’t be getting as much collagen per dose as you would with Bare Biology collagen.

Taking collagen flavoured with sugar could also be counterproductive. Sugar is known to damage the skin in a process known as ‘glycation’. When you eat something sweet, the excess sugar is attached to the fats and proteins in the dermis, producing enzymes that weaken both the collagen and its elastin fibres.

We’re 100% committed to our collagen peptides powder being as pure as possible. That’s why you won’t find any synthetic dyes, artificial flavours or unnecessary fillers in Skinful or Fundamental.

When it comes to collage, a third-party test for purity is no marketing gimmick. It’s the only way you’ll know for sure that what you’re taking is free from contaminants. 

It’s a sad fact, but the supplement industry isn’t well regulated. A product may say that it’s pure but if it doesn’t provide you with a full analysis for each batch, you’ll have to take the manufacturer’s word for it.

That’s why it’s important to look for brands that publish all their test results and, even better, gets their products third-party tested for heavy metal residues. At Bare Biology we put purity above all else.

We personally know and trust the people who make our Skinful collagen. It was the first to be MSC certified, it’s independently tested for purity and they don’t use harsh chemicals to bleach the cod skin. You’ll find the results on the Skinful collagen product page as a downloadable PDF.

Likewise, Fundamental collagen peptides are rigorously tested by our trusted supplier to ensure they’re safe, clean, and of the highest quality. This includes regular analysis for heavy metals, pesticide residues and other food contaminants such as mycotoxins. And of course, we get every batch third-party tested.

When a collagen brand proudly proclaims that its product is ‘mercury-free’, that can only be a good thing, right?

Well, it’s actually a sign that you should do some further research because it may mean that your collagen hasn’t been tested for other harmful contaminants. 

Marine collagen contains only the barest trace of the toxin anyway, both because of where it comes from and the way it’s processed.

Mercury is found naturally in the earth. When we process coal or iron near the ocean, the toxic heavy metal is disturbed and released into the water. Algae absorb the mercury and then the fish eat the algae, taking on a little more mercury every time.

But while that sounds scary, the fish only accumulate mercury in their tissue and organs, because it’s so highly fat soluble. Marine collagen is made from the skin of fish. Fish skins aren’t very fatty so even the raw collagen is pretty mercury-free. Any residual fat in the skin comes out during processing, leaving pure protein. Because manufacturers do not have to make an extra effort to remove mercury, they could all cheerfully claim to be mercury-free. But what about their levels of other heavy metals such as lead, arsenic or cadmium?
