Lactoferrine 200mg | 60 capsules | Osavi AdvancedWat lactoferrine precies is Misschien ken je de naam, maar weet je niet goed waar je aan toe bent. Lactoferrine is een ijzerbindend glycoproteine: een eiwit met daaraan vastgekoppelde suikereenheden. Het hoort bij de transferrine familie, de groep eiwitten die in het lichaam ijzer vervoert. Lactoferrine komt van nature voor in melk en in vloeistoffen zoals speeksel, tranen en slijm. In moedermelk en koudgewonnen koemelk zit het in hoge concentratie.

Wat lactoferrine precies is

Misschien ken je de naam, maar weet je niet goed waar je aan toe bent. Lactoferrine is een ijzerbindend glycoproteine: een eiwit met daaraan vastgekoppelde suikereenheden. Het hoort bij de transferrine-familie, de groep eiwitten die in het lichaam ijzer vervoert. Lactoferrine komt van nature voor in melk en in vloeistoffen zoals speeksel, tranen en slijm. In moedermelk en koudgewonnen koemelk zit het in hoge concentratie.

Hoe het op moleculair niveau werkt

Het bijzondere aan lactoferrine zit in de structuur. Elk molecuul heeft twee plekken waar het een ijzerion kan vastpakken. Die binding is omkeerbaar: het eiwit houdt het ijzer vast en kan het ook weer loslaten. In de ijzervrije vorm, apolactoferrine genoemd, staan die bindplekken leeg en is de ijzerbindende capaciteit het grootst. De ijzerverzadigde vorm heeft zijn plekken juist al bezet. Het verschil zit hem dus in hoeveel ijzer er al aan vastzit. Dit is puur een beschrijving van wat het eiwit op chemisch niveau doet. We koppelen er bewust geen verdere beweringen aan. Lactoferrine is daarbij een hittegevoelig eiwit. Bij sterke verhitting, zoals pasteurisatie of UHT, kan de natuurlijke vouwing van het molecuul uit elkaar vallen. Een grondstof die minimaal bewerkt en niet-gedenatureerd blijft, houdt zijn oorspronkelijke structuur het best vast.

Wat lactoferrine zo prijzig maakt

Veel mensen schrikken van de prijs van een lactoferrine supplement, en dat is begrijpelijk. In de markt loopt het uiteen van zo'n 15 tot 160 euro. De reden ligt in de grondstof zelf. Lactoferrine zit maar in kleine hoeveelheden in melk, dus er is veel melk nodig om een beetje eiwit te winnen. Daar komt bij dat het molecuul hittegevoelig is, waardoor de winning voorzichtig en koud moet gebeuren. Een zeldzaam, kwetsbaar eiwit dat zorgvuldig verwerkt wordt, is nu eenmaal kostbaarder dan een standaard ingredient. Bij deze formule gaat het om Proferrin, een gepatenteerde bovine grondstof. Dat de prijs van lactoferrine hoger ligt, komt dus rechtstreeks uit de aard van het eiwit voort.

Over deze Osavi Advanced-formule

Deze capsules komen uit de Osavi Advanced-lijn, de premiumreeks van het merk. Elke capsule bevat 200 mg Proferrin lactoferrine. Dat is een gangbare hoeveelheid: in wetenschappelijk onderzoek bij volwassenen wordt vaak gewerkt met 100 tot 400 mg per dag, met 200 mg als veelgebruikte waarde. Je neemt er een per dag, dus een pot van 60 capsules is genoeg voor twee maanden. Het omhulsel is van plantaardig HPMC (hydroxypropylmethylcellulose) in plaats van gelatine. Als suikervrije vulstof zit er inuline in. De grondstof is gewonnen uit koemelk, waardoor het product melk en lactose bevat. Goed om te weten: door die koemelkherkomst is het niet geschikt bij een koemelkallergie en niet voor veganisten.

Eerlijk over de regels rond claims

Een ding willen we open op tafel leggen. Voor lactoferrine bestaat op dit moment geen door de EFSA goedgekeurde gezondheidsclaim, en de beoordeling staat on-hold. Daarom lees je op deze pagina alleen wat lactoferrine is en hoe het molecuul werkt, en geen beloften over een effect. Heel veel concurrenten gaan daar losser mee om. Wij kiezen voor transparantie, omdat je dan precies weet wat je koopt. Kort gezegd: de feiten over het eiwit en de grondstof staan hier, de rest laten we aan jou.

Medium weight minimal ingredient moisturizer!
Size: 3 Fl Oz (Pack of 1)
As with another review, I’m looking for a replacement/dupe for Eucerin Urea Repair face moisturizer which is 5% urea Skin concerns: dry rosacea, mid-40s, arid climate with 4 seasons, winters are cold and snowy and summers are 90°+ for most. This is a medium-weight moisturizer that I consider not greasy at all. It is not as hydrating as I need it to be for my dry skin type with rosacea. Thickness wise I say it is similar to a standard facial sunscreen. It does last overnight, in the morning I can still feel it in some areas. I will try increasing how much I apply in order to see if it helps with how much staying power it has. This may increase the hydration it provides and I will update my review to report back. I had a very mild stinging sensation but my rosacea is struggling since moving to a dry climate. Once I repair my skin barrier a bit, I fully expect this will cease. Due to this, I’m not going to get my husband to try it, he has constantly broken skin from severe eczema and stinging is something that makes him not use moisturizers. It’s a battle! For people in more humid climates this may be a more effective moisturizer, or those with less-dry skin than me. I never have flakes so this wasn’t a parameter for me. There is no tint. I’m not sure about white cast so I can’t rate it for skin tone. But I don’t feel there would be, this seems translucent unless you really go in with it. For me it is reasonably effective. It’s probably a good day moisturizer and I expect it plays well with sunscreen, though I would definitely let it absorb or dry down. Which is pretty standard for daytime skin care. There is a slight grippy feeling when applying, but this dissipates like the Eucerin Urea Repair does. This is not, for me, a replacement or dupe for Eucerin Urea Repair. It is a great value for the price! Overall for someone with skin like mine I rate it a very solid 4/5. I would likely purchase again for a lightweight moisturizer as a more affordable substitute for Beauty Of Joseon Dynasty Cream for day. Though this does not give me the “bounce” that does. Alas. Updated to add: I tried increasing the amount I apply, and that eliminated any grippy feeling when applying. I now apply both day and night and this has helped repair my barrier enough it doesn’t sting when I apply this. I still have a way to go before I can return to using my sunscreen, but I do work in a building with no windows so the few minutes I am outside, it’s okay if I go without. If I apply this to my eyes, it doesn’t sting them, which is great, my eyes are extremely sensitive and I hesitated, but it works out just fine. It isn’t thick enough to cause whiteheads to form on my lids, unlike some balm-type moisturizers (LRP!) and even unfortunately Bioderma Sensibio Eye+ I have noticed the backs of my hands are improved as I wipe off excess onto the backs of my hands and into my cuticles. I was genuinely surprised by this, it’s not like I don’t wash my hands. I wasn’t expecting it to have any effect, but the stinging scaley hands are gone, now my hands just feel normal, even after wearing wool fingerless gloves all day at work. I will continue to use this product and will repurchase even after my financial situation improves.

My rosacea approves
Size: 3 Fl Oz (Pack of 1)
I have Rosacea, dry, sensitive, reactive skin and perimenopausal skin. My rosacea products tends to dry my already dry skin and this has been been a great moisturizer. My skin looks dewy, dullness and dryness have improved in just 2 days; I haven't reacted with sting and redness like I usually do and when I wake up I still have a dewy not greasy face even though I sleep on my sides and toss and turn all night. Definitely going to buy again since the bottle size is good, a lil goes a long way and does not make my face react like the CeraVe.

This stuff works nicely
Size: 3 Fl Oz (Pack of 1)
So I don't typically leave reviews, but I feel like this lotion has been fantastic to me. I typically don't use lotion because I hate the feel, but my face really needed it. I have dry/oily skin. My skin gets gross and flaky, yet it's pretty oily. I've always dealt with it. I decided to go ahead and buy this stuff because I couldn't take my dry skin. It helps soooo much and you barely need any. I use a dime sized amount and really focus on my problem areas. It lasts all day, not too thick and not too watery. Not greasy at all for me and soaks in very nicely. Again, it lasts all day and I don't need touch ups, even on bad skin days. I don't ever break out and it's never clogged my pores, but to be fair I've never really had skin that's broken out much before. The one thing I did notice, before using this stuff I started noticing more fine lines around my eyes/forehead. I've been using this stuff for about a year and you can barely see them anymore. I have haven't changed my diet, it's pretty atrocious honestly, so I really feel this lotion has worked wonders on its own. Also I still have a decent amount left in the bottle and I bought it almost a year ago. I'm going to try their body lotion next. Hope this helps, or at least give it a whirl!

Excellent for hydrating & moisturizing super gentle
Size: 3 Fl Oz (Pack of 1)
I really am quite amazed by this product. I’ve been using top anti aging skincare from a very prestigious, high-end brand for a long time. I’m amazed at how inexpensive this product is and how lightweight, gentle and moisturizing it as. I’m really happy I found it. It’s really incredible for hydrating and skin that is very well hydrated looks act younger. My prior anti-aging moisturizer just never moisturized THIS well. Unbelievable . My skin looks younger .

Aquaphor Ointment
Size: 7 Ounce (Pack of 1), Style: 7 Ounce Tube
Magic healing ointment prescribed by dermatologists. I used to think it was just fancy Vaseline, but it has Chamomile and other natural nonirritating ingredients that feed the skin. Great product, and worth the extra cost. Especially good for cryogenic liquid nitrogen treatments by dermatology on precancerous lesions aftercare and surgical incisions. Soothing and not irritating. Wonderful product. Nothing like Vaseline.
