There is no definitive answer to this question as the effects of Sancos on human health have not been extensively studied. Some anecdotal evidence suggests that Sancos may cause gastrointestinal upset in some people, but there is no concrete evidence to support this claim. Overall, it is likely safe to consume Sancos in moderate amounts, but it is always best to speak with a healthcare professional before taking any supplement, especially if you have a pre-existing medical condition.
