The products
Which product should I start with?
Berberine, if the problem is the fasting number or the cravings. Ceylon cinnamon if it is the spike after meals. Inositol for PCOS and missing periods, alpha-lipoic acid for burning or numb feet, and gymnema if sweets after dinner are the fight.
Can I take several together?
Yes. Berberine with Ceylon cinnamon is the most common pair, and inositol with berberine for PCOS. Take everything with food. If two of them both lower blood sugar, check your meter more often for the first two weeks.
Can I take them with metformin or my other meds?
Ask your doctor first and bring the bottle, everything in it is on the label. Berberine, cinnamon and alpha-lipoic acid lower blood sugar on their own, so on metformin or insulin your number can go lower than you expect. Blood pressure and blood thinner medicines matter too.
Will it upset my stomach?
Berberine and alpha-lipoic acid can, taken on an empty stomach or all at once. Take one capsule with breakfast and one with dinner and most people feel nothing. A sensitive stomach can start with one a day for the first week.
How long until I notice something?
Cravings and the afternoon crash usually go quiet in the first two weeks. Fasting numbers move in weeks three to six. The A1c is a three-month average, so give it a full three months before the recheck.
Can I stay on it long term?
Most customers stay on it as long as their numbers hold. Some take a week off every couple of months, which is fine. If you stop, expect the cravings and the fasting number to drift back within a few weeks.
Will I taste or smell anything?
Berberine is bitter if a capsule opens in your mouth, so swallow it with a full glass of water. Alpha-lipoic acid can make your urine smell like asparagus for a few hours. Both are normal.
Where is it made?
Made in the USA. Every batch goes to an outside US lab for strength, lead and heavy metals. Scan the bottle and the sheet opens on your phone.
Is it vegan and gluten-free?
Yes. Vegetable cellulose capsules, no gelatin, no gluten, no soy, no dairy, no dyes, non-GMO.
Orders and delivery
How fast will it arrive?
Shipping is free and tracked from our US warehouse. The tracking number is emailed the moment your package ships.
Where do I track my order?
On the track order page, with the number from your shipping email. The first scan can take a little while to appear after the email.
Can I change my order before it ships?
Yes, if it has not shipped. Email [email protected] with your order number in the subject as soon as you can. If it has already left, keep the delivery and use the 30-day guarantee instead.
My address is wrong.
Email [email protected] right away with the order number and the correct address. It can be changed any time before it ships. Once a package is moving it cannot be redirected, but if it comes back it is resent or refunded.
I chose the refill option. How do I pause or cancel it?
From the Manage subscription page, linked in the footer and in every renewal email. Enter your email, open the link, and pause, skip or cancel in one click.
What is Priority Shipping Protection?
An optional add-on at checkout. If the package is lost, stolen after delivery or arrives damaged, a replacement ships without a carrier claim. It is selected by default and you can remove it at checkout.
The 30-day guarantee
How does the 30-day guarantee work?
You have 30 days from the day it is delivered. If it did nothing for you, email [email protected] with the order number and the full amount goes back to your card. No return, no restocking fee, no doctor’s note.
Do I have to send the bottle back?
No. Keep it, finish it or throw it away. A message is enough.
How fast is the refund?
The refund is issued within two business days of your message and goes back to the card you paid with. How soon it shows depends on your bank.
Payment
What can I pay with?
Visa, Mastercard, American Express, Apple Pay and Google Pay, through the secure checkout. Your card number is never seen or stored by Dosera.
When am I charged?
The full amount is taken when you order. Nothing is added after checkout.
