Everything you need to know:

Why should I take all three nutrients together instead of separately? +

Because you get powerful triple formula for the immune system 1,2,3. Vitamin C, selenium and zinc all contribute to the normal function of the immune system 1,2,3.
All three also contribute to the protection of cells from oxidative stress 1,2,3.
By taking just one product, you can enjoy the benefits of all three ingredients without needing to take each one separately.

Will this formula support my skin, hair and nails? +

Yes, this formula also supports this area. Zinc contributes to the maintenance of normal skin, hair and nails. Additionally, vitamin C contributes to normal collagen formation for the normal function of skin, gums and teeth. Selenium contributes to the maintenance of normal hair and nails.
This product offers a little something extra, a thoughtful addition to your routine that starts from within and also reflects outward.

Why do I need such high levels of these nutrients? +

Because optimal protection requires optimal doses. For example, at 1000 mg (1250% NRV), vitamin C contributes to the normal function of the immune system, the protection of cells from oxidative stress, and normal collagen formation.

These levels ensure your body has adequate nutrients for all protective functions.

Can I take this product every day? +

Yes. This product is designed for daily use. For the best experience, simply mix the recommended daily amount of 5 g (1 scoop) with water, stir well and drink. You can take it at any time of the day — choose the moment that fits best into your routine.

Struggling with a weakened immune system?

Do you always catch something right when work gets busy, your family needs you, or you have an important event coming up?

Here are some most common reasons for a weakened immune system:

  • Not eating enough variety
    Winter makes it harder to get immune-supporting nutrients from fresh fruits and vegetables.
  • Too much alcohol and smoking
    Both can weaken your immune system and make it much harder for your body to fight off germs around you.
  • Not enough exercise
    Your body works better when it moves regularly.
  • Winter weather
    Cold months put extra strain on your system when you need it working best.
  • Spending time in crowded indoor spaces
    More people around mean more chances to pick something up, so make sure you maintain good hygiene practices.

Ready for a real solution? Meet the 3-in-1 formula for your immune system ¹˒²˒³

Triple support for the immune system1,2,3

This unique formula provides three essential nutrients that all contribute to the normal function of the immune system¹²³.  By taking just one product, you can benefit from all three ingredients at the same time and give your body a little more care each day.

High-potency vitamin C

Each serving provides 1000 mg of vitamin C (1250% NRV). Vitamin C contributes to normal collagen formation for the normal function of skin, gums and teeth¹ and contributes to the protection of cells from oxidative stress¹.

With such a wide range of important functions, vitamin C is an essential choice for anyone who wants to give their body the very best. It’s a simple addition to your routine that can make a meaningful difference.

Essential mineral support

Selenium contributes to normal thyroid function² and zinc contributes to normal cognitive function³, normal DNA synthesis³ and normal macronutrient metabolism³.

These minerals play important roles in several everyday body functions.

Beauty support from within

Selenium contributes to the maintenance of normal hair and normal nails², while zinc contributes to the maintenance of normal skin³.

Vitamin C contributes to normal collagen formation for the normal function of skin, gums and teeth¹.

Together, these nutrients offer a thoughtful way to care for your natural beauty from the inside out.

Superior absorption

Powder supplements allow for optimal absorption of zinc, selenium and vitamin C, helping your body make the most of these essential nutrients.

Reasons to start using Vitamin C + Selenium + Zinc today

If you start using Vitamin C + Selenium + Zinc TODAY:

  • You contribute to the normal function of the immune system¹˒²˒³
  • You contribute to the protection of cells from oxidative stress¹˒²˒³
  • You get 1000 mg of vitamin C, which contributes to normal collagen formation for the normal function of skin, gums and teeth¹
  • You contribute to normal energy-yielding metabolism¹
  • You contribute to normal thyroid function²
  • You contribute to normal cognitive function³

If you start taking it later:

  • You miss the benefits of three nutrients for immune function
  • You delay protecting your cells from daily oxidative stress
  • You postpone supporting your skin, hair and nails within
