<p>I tried it but not long enough to notice anything specific. However I think the idea is to use this in conjunction with many healthy diet changes. I first read about it on the Weston Price Foundation, which is a good source of information.</p>
<p>It’s important not to confuse fish oils with fish liver oils.</p>
<p>Fish liver oils, such as cod liver oil, contain vitamins A and D as well as omega-3 fatty acids. The amounts of the vitamins vary from one brand to another. Getting too much of these vitamins – especially vitamin A – can be harmful.</p>
<p>Vitamin overdoses are not a problem with ordinary fish oils.</p>
<p>The ad in the link is rather inaccurate in implying that Roman soldiers got their strength from consuming fermented fish oil. What they actually ate was a sauce they called “garum” that did indeed start with rotten fish but was heavily salted and spiced and was more water-based than oil. The modern equivalent of garum would be Worcestershire sauce, not cod liver oil.</p>
<p>There’s really no significant funding for nutrition or health research other than from the food and drug companies. They have nothing to gain from studying fermented cod liver oil.</p>
<p>If I were taking a multivitamin that included vitamins A and D, I would want to avoid this particular fish oil product so that I wouldn’t be getting excessive amounts of the vitamins.</p>
<p>^That’s if your multivitamin contains the preformed version (Retinyl Patmitate) of vitamin A. If it has the plant version (beta carotene, alpha carotene, etc), then you should not be concerned; with the plant versions, your body only converts what it needs.</p>
<p>On another note, raw salmon oil has much less oil vitamin A than cod liver oil, per teaspoon.</p>
<p>According to some friends who specialized in Roman history, another modern equivalent is a type of fermented fish sauce popular in Vietnam/SE Asia. The name escapes me, however…</p>
<p>Of course, it could also be argued that many of Pharma’s biggest sellers, like Lipitor, are also a waste of money. Not likely that the medical journals will print that editorial, though!</p>
<p>I suspect that multivitamins may be a waste of money, but in the grand scheme of things, it’s a pretty small amount of money. And, it’s not as likely to have the negative side effects like many of pharma’s big money-wasters.</p>
<p>I have two criteria for considering a supplement (and really any medication):</p>
<p>a) Widespread evidence to suggest that it may be beneficial in some signficant way.</p>
<p>b) Widespread evidence to suggest that it won’t hurt me in some significant way.</p>
<hr>
<p>As far as supplements go, four have passed these twin tests for me. Fish oil. A fiber supplement. Vitamin D. And a multi-vitamin.</p>
<p>The multi-vitamin is probably a waste of money, given my diet. However, I have poor thryroid function and there are some trace elements in multi-vitamins that may help with that. I probably get enough fiber without the supplement, but my cholesterol numbers improved so dramatically at the same time I started the fiber and fish oil that figure, if it’s working, leave it alone. The Vitamin D is something that is simply impossible to get enough of where I live. I’ve gotten my levels tested and have gotten my daily supplement dialed in pretty well.</p>
<p>If push came to shove, I’d keep the fish oil and the Vitamin D. Could go either way on the fiber and the multivitamin.</p>
