Protein powder can be potentially harmful if it contains low-quality or harmful artificial ingredients, but not all protein powders are dangerous. Here’s a breakdown:

Potential Risks:

1. Artificial Sweeteners & Flavors: Some powders use sweeteners like sucralose, aspartame, or acesulfame potassium, which can cause digestive issues in sensitive individuals or raise concerns about long-term effects.
2. Heavy Metals: Some lower-quality protein powders have been found to contain heavy metals (lead, arsenic, cadmium) in trace amounts.
3. Fillers & Additives: Certain brands add unnecessary thickeners, preservatives, or colorants that may not be ideal for health.
4. Overuse: Consuming excessive protein powder, especially in place of real food, can stress the kidneys or cause nutrient imbalances.

When Protein Powder Is Safe:

High-quality brands with transparent labeling and third-party testing.

Minimal ingredients, such as just protein isolate/concentrate without artificial additives.

Used in moderation and as a supplement, not a primarily.
