Jarrow FormulasLactoferrin 250 mg - Immune-Supporting Glycoprotein - For Healthy Immune System Support & Iron Absorption - Freeze Dried - Gluten Free - Non-GMO - 30 Capsules (Servings)

This brand is potent. Unlike a lot of other supplements where I just hope it’s doing something but can’t really tell, this stuff has a noticeable effect right away. Within the first few days, I experienced side effects of just feeling crummy, like my immune system took a dip. I’ve read other people experience the same thing at first, even though the dosage isn’t that big (that means it’s potent). I decided to take it every 2-3 days for a while until the side effects subsided, and now I’m taking it every day. I’ve noticed that, in general, I feel less stressed or anxious or depressed. That result by itself is a big deal and has a lot of positive downstream effects. Apparently lactoferrin does other cool stuff too. I guess I’ll find out.

good

I took an evvy test and learned I had 0% protective bacteria in my body. I was told to start taking a high rated lactoferrin in addition to my "good girl" probiotics and kefir. I did and this is the ONLY change I made to my supplements and diet. In 3 months time, I went from 0% to 23% protective bacteria which is a massive shift in my microbial gut. So much so, that my doctor even asked what I've done different.It was this. It's pricey for a probiotic but it clearly works so I'll keep shelling it out.

This is Andrew’s wife, Lisa.Ok, so I don’t usually write reviews, but this thing that happened with this capsule is so weird, I’d like to know if anyone else has had this happen.I take quite a few supplements/vitamins in capsule form and have never this happen with any of these other than this Lactoferrin.About a handful of times now, within 15 minutes or so of taking the Lactoferrin capsule, if I burp, the powder comes up! It looks like I had been smoking it! This afternoon it also came out my nose—it was very surprising and I almost started choking!Does anyone else have this happen? Maybe they were put in faulty capsules?The Lactoferrin works well, but considering putting the contents in yogurt or something because it’s kind of gross when this happens 😆I have to give it four stars instead of five for this reason.

10 stars! After over a decade of recurrent achilles tendon problems (plus heel spurs), it had gotten so painful that it often kept me awake night. I'd begun limping badly several months ago, which started causing sharp hip pain on the opposite side. I couldn't wear shoes because of the swelling, couldn't walk a quarter mile or be on my feet more than 20-30 minutes at a time -- my whole lifestyle was shut down. Went to yet another orthopedist, this time desperately demanding action, not more useless ice and rest and walking boot again, and am in the process of a workup for probable major achilles surgery, which I wanted done tomorrow!Meanwhile, I'd started taking 500 mg lactoferrin for a minor skin irritation - I'd read about it but had never used it before. Not only did the skin clear completely in 4 days, but now, a week after starting lactoferrin, the ankle/heel and the hip pain are unbelievably improved - occasional twinges or achiness, but where it was a constant 5-7 pain level plus 10-spikes before, it's mostly a 2-3 now. In addition, the swelling around the heel is going down - the tendon itself is thickened from scarring, but the reactive tenderness and inflammation is way, way down.Turns out there is emerging research that lactoferrin reduces pain as well as inflammation by interfering with pro-inflammatory cytokines, by balancing out the excess iron that can aggregate around inflammation or infection, and it seems to modify chronic and acute pain perception, in part by binding with brain-level opioid receptors.So now I'm perfectly OK waiting 6 weeks until after the Holidays for any surgery to repair the underlying damage... last week I might have killed anyone who suggested that.

I have found this supplement to be one of the best for immune support from doing my research. I have had great immunity this time of year with this vs. not being on it. Those summer colds can be brutal. I won't be without it now and have subscribed.
