| I'm very skeptical of food additives and supplements (both fish and human) that claim to "boost" the immune system. The immune system is a dizzying array of hundreds of different components working in a very complex balance to protect the organism while at the same time not destroying it. Autoimmune diseases like Lupus and Rheumatoid arthritis are the result of overactive (boosted?) immune systems.
In the absence of any scientific evidence of this claim, I wouldn't use garlic for this reason. On the other hand, lots of people claim that it helps finicky eaters and in small doses, it doesn't cause any harm.
Me personally, i haven't been convinced and therefore have never used it.
