Every treatment comes with some risk of side effects, but Beam’s active ingredients (CoQ10, riboflavin, and magnesium) have generally been shown to cause minimal side effects. These include bloating, diarrhea, nausea, and stomach cramps. Riboflavin can cause urine to turn a bright yellow color, but this usually isn’t a cause for concern.
If you have kidney problems or are concerned about specific side effects, it’s best to talk it over with your medical provider before starting Beam.
