Safety & Cautions
Side Effects
- Bloating or gas when first starting
- Mild nausea on an empty stomach
- Digestive discomfort from probiotic adjustment
- Metallic or earthy aftertaste
Greens powders are generally well-tolerated, though individuals on blood thinners should be cautious due to vitamin K content, and those with allergies should review ingredient lists carefully given the large number of components. Consult a healthcare provider if pregnant, nursing, or taking medications that interact with specific vitamins or herbs.
