Based on clinical safety guidelines

Digestive disorders indicate the commonest reaction, particularly commencing with high dosage of the supplement. Symptoms occur in the form of diarrhoea, stomach cramps, and nausea, and usually occur hours after ingestion. I recommend starting with a daily quarter teaspoon of powder and gradually taking more over the weeks.

Serious drug interactions occur with blood thinners like warfarin, in which vitamin C changes how well warfarin works. There are similar effects with some antidepressants and chemotherapy drugs. Always notify your prescribing physician of camu camu use for dosage adjustments.

Those with disorders of iron overload are in special danger, for vitamin C considerably increases iron assimilation. Patients suffering from hemochromatosis ought to avoid camu camu altogether. Those who are using camu camu with related disorders should have regular blood tests made to keep a check on the iron level.

Limited research on pregnancy justifies caution. It's recognized that vitamin C benefits fetal development; however, large doses through supplements may create complications. Therefore, I would recommend obtaining nutrients from whole foods, such as citrus fruit, with oversight from your obstetrician.

Help prevent issues by using third-party tested products with authentic vitamin C listing. Recognized brands will list the concentration enough for dosing. Be careful using supplements from unknown brands without transparency about proper dosing!.
