I asked previously: Would a 1000 mg dose of purified squalene have more effective antiviral and anticancer effects than a similar dose of shark liver oil? And you answered: “This would be a superior choice to be taking for anyone concerned about malignancy because it would be more potent.” Is a 1000 mg daily dose of squalene safe to use as a routine supplement? Is that dose more appropriate for treating a known malignancy, and is so, what would be a safe routine prophylactic dose?

Anything in the range of 500 mg to 1000 mg could be taken safely on a daily basis. We know the issue of toxicity is ever-present as a concern. It is difficult to rule out the very infrequent and idiosyncratic sensitivity to things ingested, so we must exclude from consideration the rare individuals having trouble handling a particular supplement rather than have such examples dominate decisions about our recommendations that could save lives of many, many, human beings. Being ultraconservative is highly disadvantageous.
