product info & FAQ
/what-it-is
EÖS RUBY is a caffeine-free, sugar-free dietary supplement powder. Seven functional mushrooms plus grapefruit, lemon, wild cranberry, ginger, and black ginger. All in an effervescent format that fizzes the moment cold water hits it. No steeping. No brewing. No caffeine curve.
One dry, level scoop stirred into 8-16 oz of cold water gives you about ten seconds of effervescence as citric acid reacts with sodium and potassium bicarbonate, driving the actives into solution fast. The potassium bicarbonate adds a mild electrolyte note alongside the fizz.
Classified as a dietary supplement under DSHEA in the U.S. Naturally sweetened with monk fruit only. Nothing artificial.

/how-it-works
The fizz isn't cosmetic. It's the delivery mechanism. Anhydrous citric acid reacts with sodium bicarbonate and potassium bicarbonate the moment cold water hits the powder. The acid-base reaction releases CO₂, creating about ten seconds of effervescence that drives the actives into solution instantly, without heat.
The potassium bicarbonate contributes a mild electrolyte note alongside the fizz. Silica (silicon dioxide) keeps the powder flowing freely. Natural grapefruit and lemon flavors complete the sensory profile.
Use it and drink it. Don't let it sit. The effervescent reaction happens fast and the actives are in solution.
/directions
Adults: mix one dry, level scoop into 8-16 fl oz of cold water. Stir with a teaspoon or shake for 1-2 seconds until dissolved. For a lighter flavor, use more water. Enjoy up to twice daily. Do not exceed two servings per day.
Cold water is best. Heat can compromise the effervescent reaction and may degrade some of the botanical actives. Use it promptly after mixing. Don't let it sit.

/faq
Can I take this if I'm on medication?
Grapefruit is known to interact with certain medications by inhibiting an enzyme (CYP3A4) that your body uses to metabolize many common drugs. If you take prescription medication, ask your pharmacist before using this product.
Is it safe during pregnancy or nursing?
Consult a healthcare professional before use if you are pregnant or nursing.
Why does it fizz?
Citric acid reacts with sodium bicarbonate and potassium bicarbonate the moment water is added, releasing CO₂ bubbles. Same chemistry as effervescent tablets, in powder form. The fizz drives the actives into solution instantly without heat or steeping.
Does it contain caffeine?
No caffeine. No stimulants. The energy support attributed to cordyceps works through its role in cellular energy metabolism (ATP production pathways), not via caffeine or any other stimulant compound.
Is this a dietary supplement or a food?
EÖS RUBY is classified as a dietary supplement under DSHEA (Dietary Supplement Health and Education Act) in the United States. It is not a drug, and the structure/function claims on this page have not been evaluated by the FDA to confirm they treat, cure, or prevent any disease.
