Rated 5 out of 5 by from yes, it is effective. first time tryout: can feel the effect on the third day, if I was half my age I would not have tried it, but as I feel the need for a supplement that may work for a certain specific reasons: this one worked well and will buy again, yes will recommend it to my friends.

Rated 3 out of 5 by from 50% fillers The contents of the 2-capsule dose exceeds 2 grams of powder. Yet, the amount of colostrum contained in those 2 capsules: 1 GRAM. Thus, the price is 2x what it appears to be. Half of it is filler.

Rated 5 out of 5 by from A WINNER --- STRAIGHT FROM THE HORSE'S MOUTH Swanson's Ultra High Ig Colostrum 500 mg. capsules are an essential part of our wellness programs - - - - for every member of the family from my kids (adults now) to myself. For me, High Ig Colostrum is not only part of my ultimate health and wellness program, but also my daily joint-health regimen. Personally, I take 2 or 3 capsules once or twice daily, as I feel the need. I am a huge proponent of babies being nursed, and one of the reasons is the colostrum they get being breast fed right from the very beginning. All four of our babies were breast fed. So they all started out well fortified with a good foundation of Colostrum. I'm glad they can keep up with their Colostrum today, using this outstanding Swanson product. This High Ig Colostrum from the Swanson Ultra Line is an excellent, higher quality, more effective product than others I've looked at. I even gave all my foals IV Colostrum. Of course, they nursed from their healthy, well-nourished mare mothers, but I wanted them to have that extra boost from additional Colostrum. So I had one of my equestrian vets come over and give each foal a Colostrum IV right after each colt or filly was born. I've done this over a hundred times, and it absolutely, definitely makes a noticeable difference in their overall growth, wellness, presence, and performance at a championship winning level. Hey, --- Works for my horses. Works for me.

Rated 5 out of 5 by from Can't live without it I've been using Colostrum for about 7 years and I find it's the best way to increase my immune system. I seem to have quite a high tolerance now for staying healthy.
Date published: 2013-12-02
Rated 5 out of 5 by from Great value This is the best deal for high IG colostrum online. All of the 45% IG supplements I've seen are derived from blood serum so if you're looking for the strongest colostrum you can buy it seems that it's 40% IG, like this one here. Capsules were of ordinary size and easy to swallow.

Rated 5 out of 5 by from So Far So Good I have only been using this product for a few weeks, but it seems to be doing what I need it to, boosting my immune system. Hopefully it continues to work.

Rated 5 out of 5 by from Best Colostrum for Price This colostrum is awesome and really helps me in every way it is supposed to. My health is much improved overall taking this product!

Rated 5 out of 5 by from Great product This product has been very helpful in giving me added strength and stamina. I'm amazed at how much better I feel since I started taking it.

Rated 4 out of 5 by from good product I have only been taking this for a month so I haven't really seen any of the benefits. But, if I forget my daily dose I do feel it. It helps greatly with recovering after a workout. I have fibro so a workout usually means I take an extra day or two to recover. I really noticed a change since taking this. This is of course a personal change, and I am not saying everyone will experience the same thing. I have taken colostrum in the past and also had wonderful results with it immune system wise. Worth giving it a try.

Rated 5 out of 5 by from Feeling like Superman For years now I have known first hand the benefits of Colostrum to the human immune system. In Australia, Colostrum is both very expensive - and not highly available (and also talked about as if it were some sort of black magic). Over the previous years I have used expensive products available within my own country, but have found that Swanson's proprietary colostrum formula, although much less expensive than others available in Oz, is actually just as good (if not better) than anything I have utilised previously. Since starting on Swanson's High IG Colostrum, my usually low-ish immune system has flourished and I am now feeling a greater sense of well-being than I have in a long time. As far as I'm concerned, Swanson's Colostrum is a greatly superior product at a very affordable price - and this has made a very positive impact on my overall health and well-being. I recommend this product to anyone that is often feeling run-down, or lives a busy lifestyle... but most importantly, it can be taken daily by all - as a booster to your immune system. Colostrum is mother nature's Super-Food! Get some and you'll never look back! :)

Rated 5 out of 5 by from Spectacularly Effective This supplement has been the best immune booster I could imagine...I've recommended it to everyone I know, and I would not be without it ever again!

Rated 5 out of 5 by from Exactly what I was looking for. If you are looking for Colostrum, then this is is the best in my opinion. The right price, the right potency etc!

Rated 5 out of 5 by from Wonderful Product I ordered this product on the review of it being better then probiotics, and you know it really is. I read the reviews like I always do and even did research on the product, and it is doing everything it claims to do. The other wonderful thing about this product is, it is alot cheaper and you get more then the other products too. I have been buying from Swansons for a couple of months now and I thank God everyday that I discovered this website. I have told all my family and friends about Swansons. Thanks for another great affordable product.

Rated 5 out of 5 by from Great product. Great price. Bovine colostrum is an item that I have used in the past to increase my energy and improve my immune system. Unfortunately it is an item I frequently let go when needing to save money. Swanson's great price allows me to continue taking colostrum without breaking the bank. Keeps me on a continued path of energy and wellness.

Rated 5 out of 5 by from Very Pleased with the results Since our environment is full of the unknown, it only makes since to seek out the understood. Colostrum from Swanson is created from superior mothers milk, no surprises. We have never felt better.
