Why I Made This

I couldn't find a Vitamin C powder that did everything I wanted. The buffered formulas that were gentle on my stomach tasted awful. The ones that tasted good weren't buffered and wrecked my gut. And nobody was pairing Vitamin C with quercetin and luteolin even though people who prioritize Vitamin C tend to benefit from flavonoid support too.†

So I made a buffered vitamin C powder that does all three.

How to Take It

Mix one scoop into filtered water any time of day, with food or without. If your stomach is on the sensitive side, taking it with a small meal makes it even gentler.

For an upgraded hydration drink, stir half a scoop into Optimal Electrolyte. It pairs perfectly.

  1. The person who gave up on Vitamin C — every formula they've tried has caused stomach cramps, bloating, or loose stools. They've stopped taking it altogether but know they need it.
  2. The person who can't stand the taste — they've tried the chalky buffered powders and the sour ascorbic acid ones. Neither makes it into the daily routine.
  3. The person who wants to support their immune system year-round — they're taking Vitamin C already but want a formula that works harder with added flavonoid support.†
  4. The histamine-sensitive person — they want Vitamin C and quercetin together in one formula to support healthy histamine metabolism and a balanced immune response.†
  5. The high-dose Vitamin C user — they know the research, they want 2,000 mg or more daily, and they need a form their gut can actually handle at that level.†
  6. The clean-label buyer — no citric acid, no sugar alcohols, no artificial anything. They read every ingredient and put most products back.
  7. The person supporting their skin and connective tissue — taking Vitamin C intentionally to support collagen synthesis, skin quality, and healthy aging.†
  8. The athlete or active person — supporting connective tissue integrity, antioxidant defense, and immune system function during heavy training.†
  9. The parent — looking for a clean, great-tasting Vitamin C powder the whole family will actually drink without a fight.

Reviews Summary
Customers say this powdered supplement dissolves easily in water and offers a convenient way to take their daily dose. Many reviews mention the citrusy, tangy flavor, with most finding it pleasant though some note it's quite sour. Common feedback includes appreciation for the powder's mixability, though several mention some settling at the bottom of glasses. While most enjoy the taste, a notable number of long-time users express preference for the previous formula. Reviews frequently highlight the product's travel-friendly nature and ease of adjusting serving sizes. The powder's texture and container shape receive mixed feedback, with some finding the tall container and powder consistency challenging to handle.

    Thank you for reaching out, and I'm sorry for the concern this caused!
    Clumping in powdered supplements like our Electrolytes is a natural occurrence and is completely normal. Electrolyte powders contain mineral salts that are naturally hygroscopic, meaning they attract and absorb moisture from the air. Even small amounts of humidity (from opening the container, storage conditions, or ambient moisture) can cause the powder to clump together.
    The good news is that this does not affect the quality, safety, or effectiveness of the product. The clumping is purely a physical/textural change, not a chemical one, so the electrolytes are still just as potent and safe to take. You can simply break up the clumps with a spoon or the back of a scoop before mixing, or give the container a gentle shake before use.
