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.

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!
