Nourkrin tablets for men and women both contain a marine protein extract called Marilex to promote hair regrowth following hair loss. But could this ingredient cause side effects? This review explores effectiveness, safety and risks that might apply if you take Nourkrin tablets (or the very similar range of tablet products called Viviscal).
As with almost all other manufacturers (or so it seems) there are a
several products in the Nourkrin range, but the main products are two food
supplements – one for men and one for women. However, if you take a
close look at the ingredients of these two products, you’ll see that
there’s not a great deal that separates them.
Nourkrin Man has identical ingredients to Nourkrin Woman except that it also contains cod liver oil* and the spice fenugreek.
* The cod liver oil provides vitamins A and D, as well as the essential fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) which are known collectively as omega 3.
The product information pages on the official website states that both products contain acerola extract – a fruit which, along with several other nutrients, also provides vitamin A. So obviously the cod liver oil will provide an extra dose of vitamin A for men in their product.
Although there’s only a few small differences between the ingredients of these two products, you might nevertheless wonder why the product for men has additional ingredients to the product for women? The answer is most likely because, hair loss is usually much more severe in men than it is in women, and so, can be more difficult to treat.
So that raises another question: What is it about cod liver oil and fenugreek which gives extra help towards hair regrowth?
Cod Liver Oil – the omega 3 content in cod liver oil acts as a powerful DHT blocker. And since DHT levels are higher in men than in women, it makes sense to try and keep DHT levels down (DHT, of course, being the hormone with a big link to hair loss). Learn more about essential fats for hair growth.
Fenugreek seeds – a phytoestrogen with high antioxidant content and a number of beneficial qualities including blood vessel dilation – something that should improve blood circulation and so encourage healthy hair growth.
I think it should also be pointed out that there's nothing about these extra nutrients that’s specific to men. In other words, there's no reason why women shouldn't take vitamins A and D, omega 3 and fenugreek too. In fact, fenugreek trials have shown some positive effect on hair growth in both men and women when taken as a food supplement.
But quite apart from these two ingredients, according to the website, what makes Nourkrin different from other similar hair regrowth supplements is another ingredient, Marilex.
This is a special blend of marine proteins extracted from shellfish and fish (shark cartilage) which, it is said, can have a beneficial effect on the hair growth cycle. It should be noted that Marilex is not simply collagen (marine-sourced collagen being another protein that’s sometimes found in food supplements).
Hair is made almost entirely from protein, so perhaps you might think that you can help your hair regrow simply by taking extra protein? No, I don’t think that’s true at all. From a nutritional point of view, you should be getting enough protein from the foods you eat, as highlighted by the fact that the hair all over the rest of your body, your face and your scalp (i.e., outside of the affected hair loss region) continues to grow perfectly well.
So, for that reason, I’m not really convinced that marine protein can especially help to encourage hair regrowth. And this belief is perhaps supported by user experience.
Like most other hair loss products, reviews are mixed. Some people say it helps (and there have been clinical studies which show positive outcomes too). But, others say it didn’t help at all (even after six months or more), that they had side effects (which could be a reaction to the shark or shellfish content) and that they wouldn’t recommend it.
So, for both men and women, whilst these tablets do contain totally natural ingredients and, as such, may sound like they should be healthy* for you, that doesn’t necessarily mean it will be worth your while taking it for hair loss.
* Important: Anyone allergic to fish or shellfish should not
take Nourkrin tablets. It's best to consult with a health advisor before taking
food supplements. This is especially true of vitamins A and D (both of which are contained in Nourkrin tablets). That’s because, along with vitamin E, these fat soluble vitamins can
slowly accumulate inside your body if you take more than you need (something which will not happen with water soluble vitamins). And,
in excess, side effects and health issues caused by toxicity can then develop.
