5 Time Clinically tested Mulberry Extract
Finally Something That Works
Our mulberry extract with concentrated DNJ has been clinically tested five times with people and shown to moderate after meal blood glucose spikes due to carbs & sugars by a group average of 40%.
When taken in advance of a meal StayLo gets ahead of the food you eat to reduce the enzyme activity that sends sugar into the bloodstream.
By bypassing the bloodstream StayLo is repeatable each and every meal with no side effects.

After-meal blood sugar levels from a single healthy individual. Results will vary.
Safe, Repeatable, & Water Extracted DNJ
What is StayLo
Long-known leaf extract concentrated 50x for more power using the latest water extraction technology.
StayLo contains concentrated mulberry iminosugars, including 1-deoxynojirimycin (DNJ) that have long been used but never available before in an isolated extraction. Iminosugars look like glucose to the body and temporarily reduce the absorption of carbs & sugar after a meal without needing to enter the bloodstream. The excess glucose is turned into prebiotics for the microbiome.
We constantly test Staylo vs everyday foods; these blood sugar testing results are from single healthy individual tests.
Results may vary. See More
“This is a revolutionary product. I’ve been looking for something like this for years.”
Steven Willey, M.D.
This is the first non-prescription, clinically studied supplement that produces a profound and immediate reduction in the impact of complex carbohydrates and sucrose in healthy people. Importantly, StayLo has a straightforward mechanism of action by decreasing the activity of the enzymes that digest carbohydrates including sucrose.
Consistently moderating carbohydrate impact at mealtime supports healthy blood sugar levels, resulting in a cascade of metabolic improvements including balanced insulin sensitivity.
Amazingly StayLo promotes these benefits without a change of diet when used as directed.”*

Dr. Willey does not provide medical advice to anyone except his patients of course. His opinion is based on a review of clinical studies and scientific literature.

We would love to hear from you. Please share your thoughts.
Thank you so much for making this, my blood sugar has never been better after a month and I can feel the lack of weird stomach bloating and energy crashes. My dr is going to love this
Will this make you lose weight
This will help with weight loss if coupled with a change in net caloric deficit but it is not designed to reduce weight.
Seems no side effects?
In clinical trials, StayLo had no side effects that exceeded those of the placebo group. If you have concerns about side effects, you should consult your physician.
😮👉I was really hoping to see that it would reverse they type 2 diabetes cause thats what we need. I hate taking pills especially metformin. My a1c is off the charts,and my cholesterol.😭👉I hate this disease.
So I take 4 shots a day. Can I still try the Staylo or should I ask my doctor first?
Great question, our company cannot offer medical advice. If you are taking medication you should direct your healthcare provider to the Healthcare Professional page on this website and follow your healthcare provider’s guidance. You may also print the Healthcare Professional page and take it on your next visit to your provider.
Will it give you diarrhea? Like al
In clinical trials, StayLo had no side effects that exceeded those of the placebo group. If you have concerns about side effects, you should consult your physician.
When I follow a low carb diet my weight improves.
I can keep my carbs under 15% of my diet 90% of the time.
I am looking for something to take only when I find myself about to eat a high carb meal. Would I be able to take this on occasion as a premeal carb blocker?
Absolutely, this is exactly what StayLo excels at. Just make sure to take it 15 minutes before your first bite.
Is it FDA approved? Does it give you energy? How many capsules a day?
The FDA recognized it as GRAS (Generally Recognized As Safe. Under sections 201(s) and 409) it does give energy by reducing the blood sugar crashes by up to 40%, you want to take it 15 minutes before each meal, ideally the two largest carb containing meals.

Does this require daily use to be effective? Or can it be used only when I know I am going to have a carb-heavy meal?
When carb (starch and sugar) levels in a meal are high, there is more for StayLo to block, preventing a major blood sugar spike. Even a few slices of bread can boost blood sugar levels, so taking StayLo consistently over time will yield the greatest benefit to metabolic health for most people. We recommend taking StayLo twice a day – one capsule at least 15 minutes before your two biggest meals of the day.
Can you take it with all three meals ? Not just two?
Try it and if it causes any gastrointestinal pressure, cut back to the recommended dose of two per day at your largest two meals.
Does this help you loose weight?
When used consistently, StayLo may help effectuate weight loss. We have reports from users that they have experienced weight loss.
However, at this time, we have not yet performed clinical studies to prove that StayLo causes weight loss. Human weight loss studies are difficult due to the length of the study period required. Additionally, human weight loss studies must attempt to reconcile individual variables in dietary intake and metabolic condition of participants prior to and during the study period. On top of that there are voluntary reporting requirements for study participants that sometimes lack accuracy.
We are considering a StayLo weight loss study in mice where these problems can be largely eliminated, but the mouse study has not yet been performed.
We already have proof that the StayLo product produces amazing changes to metabolism. We expect that StayLo may cause or assist in causing weight loss when used as directed, but we do not and will not make a weight loss claim for StayLo until we have firm scientific evidence.
do you offer a sample
Not at this time, sorry.
yes samples or smaller bottles if they dont work thanks
Will it help me to lose the weight that I can’t lose on my own. I find it hard to find something that will really work.

I love wine. Does it work on the sugar in alcohol?
It can work with the sucrose that is added to many alcohols and mixed drinks but the small amount of fructose in wine StayLo doesn’t work on.
can I buy in larger quantities than 1 without a subscription? Thanks-
Yes you can buy as many as you want by adjusting the quantity option in the checkout. Also the subscription can be canceled at any time before the next shipment.
How big are the capsules? The last type I ordered for this purpose came as very large capsules that I could not swallow at all.

Thanks for this important question. If you are taking medication, you should consult with your physician prior to using StayLo or any nutritional supplement. We have a healthcare professional page on our website for your doctor to review that could help more.

The cost is too high for us old who live only on SS would love to try it bot the cost
Thanks for your comment. We are always trying to find a way to reduce cost. StayLo has a high level of quality control and purification. It’s not the cheapest, but it is the strongest supplement of its type. We will keep trying to find ways to reduce the cost.
Good evening. I am a pretty healthy 69 year old. I exercise 6/7 days a week religiously. The only medication I take is for an enlarged prostate. At my recent yearly physical, my glucose level was just above the recommended range for the first time ever. Is this a good product for someone like me? Thank you for your response
Sounds like you are doing everything right! It is great that you are getting out in front of a potential blood sugar problem. Due to FDA regulations, we are not allowed to comment on whether our product would be good to head off future increases in your blood sugar. We recommend that you show your doctor the Health Care Professional page on our website. He or she can then advise on the suitability of the StayLo supplement.
You say there are studies that proves it works show me the studies
This part of the site has it all broken down for you. https://staylolife.com/healthcare-professionals/
I need really diet help!
will this gave you gas? My stomach get up set very easy.
If taken only twice a day it does not in our trials but having said that every person is different and StayLo does create a prebiotic in the digestive system which if a person is susceptible to gas from eating prebiotics then they might but only in a very limited level well under say, a can of beans.
after you take pill how long does it stay in your system?
Since StayLo doesn’t enter the bloodstream it has a limited window of use each time you take it of about a little over 1 hour. So you need to take it 15 minutes in advance and then finish the meal within an hour or so.
