What is YayDay?
Think of it as your gut’s nighttime BFF. YayDay is a daily super supplement that supports digestion, gut health, and overall well-being—while you sleep.
How does YayDay work?
YayDay is your gut’s daily reset—fueling digestion, nourishing good bacteria, and keeping you light, regular, and balanced.
When will I see results?
Most people start feeling the magic in 1-3 days—better digestion, smoother mornings, and deeper sleep. But for the full gut glow-up, we recommend committing to all 7 days. Consistency is key!
How do I tale YayDay?
Easy peasy. Mix one packet or scoop with 8 oz of cold to room temp water before bed—some of us even take it over ice. YayDay on the rocks? Yes, please.
Can I take YayDay in the morning?
YayDay works best at night, when your body naturally resets and digestion is in full swing. For the best results, we recommend sticking to an evening routine.

3-in-1 Super Digestive Supplement – Formulated with prebiotic fiber, clinically studied digestive enzymes, and gentle magnesium glycinate, this water soluble fiber powder works while you sleep to restore gut balance and help you wake up feeling lighter, clearer, and more regular.
Prebiotic Fiber Blend for Daily Regularity – Our unique formula is a combination of soluble and insoluble fibers, using psyllium husk, inulin, oat fiber, and flaxseed powder to promote smoother digestion in a healthy gut microbiome. Designed to be taken at night, this prebiotic powder supports comfortable, overnight motility.
Digestive Enzymes for Bloat Relief – Powered by HemiSEB, our digestive enzyme complex helps break down complex fibers to minimize the bloating and gas often associated with traditional fiber supplements. It’s not just easier on your gut — it’s smarter digestion, by design.
Magnesium Glycinate for Sleep – Quality sleep fuels a healthier gut. YayDay includes gentle, bioavailable magnesium glycinate to support relaxation and deeper rest, so your digestive system can harness the time it needs to reset, repair, and rebalance while you sleep.
Wake Up & Yay – YayDay was created to help you reclaim your rhythm. It’s more than a supplement — it’s a habit that transforms how you feel from the inside out. Unstoppable Gut, Unstoppable You.

This product works great.
I got a sample and ever since I have been using this product. I’ve struggled for years with using the bathroom regularly after using this product the 2nd time I’ve gone regularly since. Not only does it help with that I also sleep a lot better. I 10 out of 10 recommend this product if you need help going regularly or even just help sleeping this product is for you. It’s easy to mix I just use water and it taste good.

Sweeteners are bad foe the gut
The sweeteners like Stevia and chamomile have had a significant negative effect on my gut. I have seitched to a product without the unnecessary sweet

Actually works and tastes delicious!
I’ve been taking Yayday for awhile now, and it’s been a game-changer. It tastes delicious (with no weird aftertaste) and has helped significantly to keep me regular and bloat-free. It’s also nice not having to buy separate supplements for fiber and magnesium anymore and my sleep has never been better. Having both covered in one supplement has also saved me some $ so I’ll definitely be sticking with it and highly recommend!

YayDay is by far the best!
I’ve tried the many various digestive supplements, and YayDay is by far the best in every respect! It has significantly improved my regularity, sleep schedule, and fiber intake, which is especially important for me in my 70s. I’ve experienced consistent, healthy bowel movements, better rest, and refreshed mornings. I wholeheartedly recommend YayDay for its incredible impact on overall well-being.

Very Goopy
I take a fiber supplement every day and have for years, so I thought I might give this a try. I used it in a cider I take before bed the first time and it turned it into a mealy, mucousy like drink that was very challenging to swallow—it also made it taste like oatmeal. I have since tried it in a number of other drinks and found that it either needs to be consumed in a very large quantity of liquid or in a very viscous liquid like a smoothie. As for the health benefits, its hard to say that is is effective, but the fiber is always good. Not sure I’d recommend this, and its pretty costly, so it’s a pass from me.

Love this stuff!
After incorporating YayDay into my routine, I noticed a solid improvement in my digestive health—no more bloating or discomfort. The flavor isn’t overpowering, which is a plus for those sensitive to taste, and it feels good knowing I’m supporting my gut in a straightforward, no-nonsense way. If you’re looking for a supplement that’s effective, YayDay is good choice!
