Consumption of pearl powder in individuals with favism?

Hello, I have a personal history of favism and have been advised not to consume pearl powder.
Recently, I noticed that some beauty and health products contain pearl powder, so I searched for information related to favism.
I came across online posts stating that pearl powder is safe for consumption, but it should not contain heavy metal contaminants.
However, I have not found any relevant literature to confirm this.
I would like to know if the information online is accurate or just a rumor.
Thank you.

Hello: The main component of pearl powder is calcium carbonate, along with a small amount of carbohydrates, amino acids, and trace elements (including heavy metals), among others.
Calcium carbonate, carbohydrates, and amino acids are unlikely to cause hemolytic reactions in individuals with favism.
However, many sources advise against the consumption of pearl powder by favism patients, suggesting that the issue may lie with the trace elements (including heavy metals).
There have been instances where certain favism patients experienced hemolytic reactions after consuming pearl powder.

Although it is possible that variations in the dosage of trace elements (including heavy metals) or the severity of an individual's favism may lead to different outcomes, resulting in some articles stating that favism patients can consume pearl powder, I personally do not recommend consuming beauty and health products containing pearl powder.
This is because it cannot be guaranteed that the pearl powder consumed contains safe levels of trace elements (including heavy metals), and the severity of hemolytic reactions can vary significantly.
If you still wish to try it, please be vigilant for any signs of hemolytic reactions, such as fatigue, loss of appetite, rapid heartbeat, shortness of breath, pallor, and jaundice (yellowing of the eyes and skin, dark urine).

More Info

Favism, or G6PD deficiency, is a genetic condition that affects the enzyme glucose-6-phosphate dehydrogenase, which plays a crucial role in protecting red blood cells from oxidative damage. Individuals with this condition are particularly sensitive to certain foods, medications, and environmental factors that can trigger hemolytic anemia. Common triggers include fava beans, certain legumes, and some medications.
When it comes to pearl powder, the safety of its consumption for individuals with favism is not straightforward. Pearl powder is derived from the inner layer of oyster shells and is often used in traditional medicine and cosmetics for its purported health benefits, including skin rejuvenation and anti-aging properties. However, the composition of pearl powder can vary significantly depending on its source and processing methods.

The primary concern for individuals with favism is the potential presence of heavy metals or other contaminants in pearl powder. Some pearl powders may be sourced from environments where heavy metals are prevalent, which could pose a risk to individuals with G6PD deficiency. Heavy metals can induce oxidative stress, which is particularly harmful to those with this enzyme deficiency, potentially leading to hemolysis.

While there is limited scientific literature specifically addressing the safety of pearl powder for individuals with favism, the general recommendation is to exercise caution. If the pearl powder is sourced from a reputable manufacturer that conducts thorough testing for contaminants, it may be safer for consumption. However, it is crucial to ensure that the product is free from heavy metals and other harmful substances.

Moreover, individuals with favism should always consult with a healthcare professional before introducing any new supplements or dietary changes. A healthcare provider can offer personalized advice based on an individual's health history and specific condition.
In summary, while there is no definitive evidence that pearl powder is harmful to individuals with favism, the potential risks associated with contaminants necessitate caution. It is advisable to avoid pearl powder unless it is confirmed to be safe and free from heavy metals. Always prioritize products from reputable sources and consult with a healthcare professional for tailored advice.
