Potassium ascorbate
Bio-Activity Analysis
Gastric Comfort: Buffered vs. Unbuffered Vitamin C
SCIENTIFIC DATA VISUALIZATION
Health Benefits & Sources
Why You Need It
- Gentle on the Stomach: The buffering process raises the pH, making it much less acidic than pure Ascorbic Acid.
- Immune System Support: Provides the necessary Vitamin C for the production and function of white blood cells.
- Electrolyte Balance: Contributes to your daily Potassium requirement, which is vital for heart rhythm and fluid balance.
Deep Dive
Potassium Ascorbate acts as a dual-action supplement. While Vitamin C is famous for its antioxidant capabilities—fighting free radicals caused by pollution and stress—it is also a cofactor in collagen synthesis, meaning it helps keep your skin firm and your joints healthy.
Meanwhile, the potassium component helps counteract the effects of sodium. In our modern diets, high sodium intake can raise blood pressure; potassium helps relax blood vessel walls, easing tension. By combining these two, you are essentially supporting your immune defense and cardiovascular system simultaneously.
Natural Food Sources
Interestingly, nature packages Potassium Ascorbate naturally. When you eat a fresh orange or a bell pepper, the Vitamin C in that fruit is naturally bound to organic potassium salts. This is why whole foods are always superior. However, the concentration in food is generally lower than in supplements, which is why supplementation helps bridge the gap.
Top Natural Sources (Vitamin C + Potassium combined):
| Food | Amount (Vit C) | Note |
|---|---|---|
| Red Bell Pepper | 95mg (106% DV) | Also high in Potassium |
| Kiwi Fruit | 64mg (71% DV) | Contains Potassium |
| Orange | 51mg (57% DV) | Natural Citrate/Ascorbate |
| Brussels Sprouts | 48mg (53% DV) | Excellent source |
| Strawberries | 49mg (54% DV) | Good source |
Supplementation
Dosage:
- General Health: 250mg to 500mg of Potassium Ascorbate daily is common.
- Higher Needs: Up to 1000mg (1g) daily, often split into two doses.
Who should take it?
- Individuals with sensitive stomachs who get heartburn from regular Vitamin C.
- People on diuretics (water pills) who lose potassium and need to replenish it.
- Those looking to boost immunity during cold/flu season without the acidity.

Frequently Asked Questions
Safety & Side Effects
Safety & Interactions
Chemical Safety: Potassium Ascorbate is generally recognized as safe (GRAS). It is less acidic than Ascorbic Acid, reducing the risk of acid-related erosion of tooth enamel or stomach lining.
Who should avoid it or use caution?
- Kidney Disease: People with chronic kidney disease (CKD) or a history of kidney stones (calcium oxalate stones) must be careful. High doses of Vitamin C can increase oxalate levels in urine, and damaged kidneys may struggle to filter excess potassium, leading to dangerous hyperkalemia.
- Hyperkalemia: Anyone with already high potassium levels in their blood should avoid this supplement.
Interactions:
- ACE Inhibitors / ARBs: Common blood pressure meds (like lisinopril or losartan) can raise potassium levels. Combining them with potassium supplements can be risky.
- Chemotherapy/Radiation: Some evidence suggests high-dose antioxidants might interfere with certain cancer treatments. Consult your oncologist.
