Unpredictable Blood Sugar Levels? The Hidden Cause Might be Damaged Insulin

Temperature changes can weaken insulin, leading to increased blood sugar and symptoms like headaches, drowsiness, extreme hunger, increased thirst, frequent urination, and blurred vision.

Most people don't realize how fragile insulin is, and how to store it for it to work the most effectively. The VIVI Cap is an incredibly simple solution to ensure that insulin is safe to use and that none of it goes to waste.

Insulin potency when exposed to high heat over 5 days, with and without VIVI Cap 1 (As published in the academic journal Diabetes Journal, American Diabetes Association, 2018 Jul)

Did You Know?

The FDA allows insulin to lose up to 5% potency, even in perfect storage conditions.

In less than perfect conditions the potency loss can be much higher, causing unpredictable swings in blood sugar.

That means your insulin is at the risk of being damaged every day:

in your car
at work
at the beach

when traveling
in your bag
around the house or yard

Get peace of mind that lower insulin potency will never be the cause of your unstable blood sugar ever again!

How Should Insulin be Stored?

STORAGE CONDITIONS

Before first use

All insulin formulations should be stored in a refrigerator at 36° to 46°F (2°-8°C) before use to keep their quality until the expiration date.

USE CONDITIONS

After first use

Insulin must be stored below 76-86°F (below 24-30°C), but should never be allowed to freeze and should not be exposed to direct sunlight.

Always Stay in the

Safe Zone

Insulin in use that is exposed to temperatures above 86°F or below freezing can be damaged and unsafe. Injecting damaged insulin can result in fluctuating glucose levels and can be life threatening, or cause unpleasant side effects.

Do Any of These Sound Familiar?

Unexpectedly high blood sugar levels, despite following what the doctor recommended?
Sudden need to increase dosage of insulin because the previous dosage didn't have the desired impact?
Accidentally let a pen spoil by leaving it in a hot or cold car, bag on the beach, or a ski jacket?

Prof. William V. Tamborlane Chief of Pediatric Endocrinology -

As a clinician and clinical investigator concerned about better treatments for diabetes, the VIVI Cap is of particular benefit for my patients who require insulin shots, as the vast majority of patients use insulin pens for their daily injections.

Dr. Susan B. Sloane Pharmacist, Diabetes Care and
Education Specialist

I was so excited to find the VIVI Cap products. Temperature extremes affect Insulin and once that happens, the blood sugar controls get out of hand. I really think it's a life-saving product. Plus, it's all FDA registered and very easy to use.

Scientifically Proven to Protect Insulin

In an academic study published by the American Diabetes Association, the VIVI Cap was scientifically proven to be the best solution that was tested to keep insulin temperature protected once in use.

Lior, T1D

Works every time
As unlikely as it may seem, this product works as described! I have used it for a while now, and it has never failed to keep the insulin pen below higher temperatures that degrade the insulin.

Ginger Vieira, T1D

The VIVI Cap is so easy and simple!
I've lived with type 1 diabetes for over 20 years, and I worry the most about my insulin when I'm going with my kids to the beach or the pool, and I have to pack an old school ice pack in my bag and make sure that it is always in the shade. It's just tedious.. With VIVI Cap I simply throw it in my bag and go.. It's so easy!

Laura Craven, T1D

It Works to Keep Insulin Cool and Safe!
This cap works just as advertised. We use it when traveling to keep my son’s insulin cool down here in Texas and other areas of the southwest that can get quite ‘toasty’. It’s nice to store it in our fridge between uses and simply grab it on the go. It’s a great alternative to carrying a big insulated bottle with ice sticks... Thank you!

Kathy, T2D

This really works
This technology actually works to keep the insulin at a safe temperature in my purse, without bulky and melting ice packs. It's convenient and compact. You can put the Vivi cap over a pen needle for even more convenience. They are expensive, yes, but how much will an overheated insulin pen cost you? Highly recommended.

Mark Sloane, T1D

The best thing for me!
Whether working out at home, or at the gym, the VIVI CAP is a must have to keep my insulin at a controlled temperature. Don’t leave the house without it!! Highly recommended to anyone who needs to keep their insulin in the car or even in a hot gym locker for hours at a time!

Aviva Domein, T1D

Great invention
When there are extreme heat waves here in my country, the VIVI Cap just saves me! It helps me keep my insulin at a normal temperature. Highly recommended!

How does VIVI Cap work?

VIVI Cap uses a unique patented combination of special insulation with “self-regenerating” heat absorbing material and control electronics. Due to the “self-regenerated” heat absorbing material, the device operates for years without requiring any user attention or handling. There are no power requirements, no charging or batteries and no preliminary preparations needed.

Should I place VIVI Cap in the refrigerator?

VIVI Cap doesn’t have to be placed in the fridge. It automatically absorbs the excess heat, releasing it to the environment when ambient temperature is normal.

Has VIVI Cap been tested and validated?

VIVI Cap has successfully passed performance tests and the results were published in Expert Opinion on Drug Delivery 2017 Jun;14(6):709-714.
VIVI Cap is FDA and CE Registered.

What does the green light on my VIVI Cap indicate?

The green light when pushed is your reassurance that your insulin has been safely stored at the correct temperature. The light should stay on for just a few seconds enough time for you to observe the color of the indicator while preserving battery life. This assures that you will be able to use your VIVI Cap for many years to come.

What is the danger of improper storage of insulin?

Insulin in use that is exposed to temperatures above 86°F or below freezing can be damaged and spoiled. Damaged insulin is not visible to the naked eye.

This can result in fluctuating glucose levels and can be life threatening causing:
-Blood glucose fluctuations
-Increased insulin dosages
-Risk of hypoglycemia

How much does VIVI Cap weigh?

Only 2 oz (60g)! Easily fits in your pocket, purse or bag.
