Hey all, been taking these ACV gummies for about 2 weeks now. I like the energy boost, but I've noticed something weird - my pee is BRIGHT yellow, like neon almost. It's not painful or anything, just... vibrant. Has anyone else experienced this? Should I be worried?

Retired RN here! Don't panic, dear. That's likely the B12 and beet root. B-complex vitamins (especially B2/riboflavin) can cause bright yellow urine - it's just excess being excreted. Beet root can tint it too. As long as you're not experiencing pain, fever, or dark urine (like cola-colored), you're probably fine. Drink plenty of water! How's your energy otherwise?

lol yeah mine too! Been paleo for 5 yrs, added these gummies last month. My pee looks like highlighter fluid sometimes. But my digestion has never been better - no bloating after meals. The beet root is a strong pigment. As long as you're eating clean and hydrated, it's just your body using what it needs and dumping the rest.

Fascinating! I track all my bio-data with wearables. Noticed the same urine color shift around day 10 of taking these. My sleep tracker also shows improved REM cycles - maybe related? The B12 is probably boosting your system. Try logging your water intake with an app like HydroCoach to see if hydration affects the color intensity. Tech solves everything!

Thanks everyone! Feeling reassured. @CitrusClaire435 no pain or fever, energy is great. @GreenGreg452 highlighter fluid is the perfect description haha. @HealthHacker41 I'll check that app - maybe I'm not drinking enough. Appreciate the insights!
