I keep getting colds anyone tried colostrum

<p>I keep getting colds this winter.</p>
<p>Travel to and from work on trains and busses really busy & packed in like sardines, think I keep picking up other peopels germs.</p>
<p>Wash my hands and use anti-bacterial hand wash and avoid touching my face.</p>
<p>Have stopped running but cant shift it, heard that colosrtum can strengthen the immune system and speed up recovery.</p>
<p>Has anyone out there tried it and did it work?</p>
<p>willing to try anything.</p>
<p>Any ideas?</p>
