Why increase your Vitamin D levels?
- Supports respiratory health
Research indicates that Vitamin D helps support upper respiratory health.
- Modulates Oxidative Stress While Supporting Immune Function
Vitamin D helps reduce oxidative stress at the cellular level. By increasing Vitamin D levels, you can also support your immune health
- Vitamin D Supports the Activation of T-cells
One way vitamin D supports immune health is to support the activation of immune T-Cells...an important part of our immune system
- Activate T-cells whose job it is to destroy pathogens — such as viruses
T-Cells require Vitamin D to mobilize and fight off foreign pathogens. Without sufficient Vitamin D, t-cells are unable to activate, leaving your body potentially vulnerable to disease.
Why supplement your health with Vitamin A?
- Increases the amount of T-cells produced in the body
While Vitamin D helps activate T-Cells. Vitamin A supports the production of IgA, another important immune cell.
- Supports your heart
Vitamin A is known to help support your heart, immune function, cell growth and cell reproduction.
- Strong Antioxidant
Vitamin A is a strong antioxidant that helps fight free radical damage and promotes healthy aging.

This awesome compound is designed to support your immune health.

Studies have shown that Vitamin A increases the number of both T and B lymphocytes (immune cells) and also increases the immunoglobulin IgA which coats all our mucus epthelium in our noses, lungs, GI tract. These are important elements of our immune system.
Vitamin D proteins pair up with Vitamin A proteins in what is called a heterodimer. This complex can then bind to a Vitamin D receptor and this causes the CAMP gene in immune cells to secrete defensin, cathelicidin and LL-37 all of which support the production of more immune cells.
Cell Block requires only 2 doses once a month to help support your immune health.
Choose 2 back-to-back days when you will take your dosage.
Take your first dose of Cell Block. Wait 24 hours, then take your second dose! Repeat this cycle once a month.
Just once per month! Cell Block is hassle free and easy to use!
- 1. Is it safe to take high serving Vitamins like A and D?
Cell Block was designed to be taken for only 2 days, then only repeated after 4 to 6 weeks. This allows your body to utilize the amounts it needs, then eliminate what it doesn’t over that course of time. This product should not be taken on a daily basis.
- 2. Does Cell Block support respiratory health?
We have paired these two vitamins together because research suggests that they provide strong support for our upper respiratory and immune health.
- 3. Can my children take Cell Block? They are in school, and I want to protect them.
We don’t recommend children under the age of 15 take Cell Block. It is always advised to consult with your pediatrician before giving your child this product.
- 4. If my pediatrician says it’s okay, what is a typical children’s serving?
If your pediatrician gives the okay, then we recommend only giving them only 1 serving from the 2 day dose of Cell Block.
- 5. How can taking vitamins for only 2 days support me for an entire month?
Cell Block contains Vitamins A and D. These vitamins are fat-soluble, which means that they stay in your system for a longer period of time than water-soluble vitamins, like Vitamin C. Therefore, you typically don’t need to continue to “top off the tank” with the fat-soluble vitamins like A, D, E, and K.
