# Claim table — baking soda / sodium bicarbonate health video

| Claim / issue | Evidence label | Notes |
|---|---|---|
| Baking soda is sodium bicarbonate and can neutralize stomach acid. | Supported, narrow. | Sodium bicarbonate is an OTC antacid for temporary heartburn/acid indigestion relief, but it can interfere with stomach acidity and medication absorption. |
| Baking soda improves athletic performance. | Partly supported for specific uses. | Reviews support acute ergogenic effects mainly for high-intensity efforts, especially anaerobic capacity/events roughly under several minutes; effects vary and GI side effects are common. |
| Sodium bicarbonate helps some CKD patients with metabolic acidosis. | Supported only as clinician-managed therapy. | Reviews find it raises serum bicarbonate and may help selected CKD/metabolic-acidosis patients, but dosing and monitoring belong with clinicians. |
| Baking soda detoxes the body, pulls toxins through the skin, removes heavy metals, or resets whole-body pH. | Not established. | Human pH is tightly regulated; the source trail found no clinical evidence for baking-soda foot soaks or household protocols as detox therapy. |
| Baking soda helps weight loss, blood sugar control, mental clarity, or lifespan extension. | Not established / overclaimed. | The video makes broad wellness claims without a matching level of clinical evidence. |
| “Cancer hasn’t got a hope” once alkaline routines are used. | Unsafe overclaim. | NCI states there is no proof an alkaline diet can slow, cure, or keep cancer from coming back; cancer care should not be replaced by baking soda or diet trends. |
| Barbara O’Neill is a reliable authority on baking-soda cancer claims. | High caution. | NSW HCCC permanently prohibited O’Neill from providing health services after findings about non-evidence-based and dangerous advice, including bicarbonate-soda cancer claims. |
| Baking soda is harmless because it is common and natural. | False if used improperly. | Case literature and drug references describe metabolic alkalosis, electrolyte imbalance, sodium load, drug interactions, kidney/heart risks and rare stomach rupture from misuse. |
