Strengthening your immune system can help support your body in keeping you healthy. Vitamin D is important for your immune health, but it also has unique properties in the body that make it different from any other vitamin.
Overall, we always would recommend you speak with your healthcare provider before starting any dietary supplement to make sure it aligns with your personal health needs, as well as your current medication or supplement routines.
Vitamin D
Most of us do not get enough vitamin D from diet and sunlight alone to provide optimal immune health. Only d.velop™ vitamin D is made with calcifediol which is absorbed directly into your bloodstream. This means it’s 3x faster at increasing your vitamin D levels and 3x more effective than conventional vitamin D, helping you meet your health and immunity goals when taken twice daily (2400 IU, 20 mcg) (Quesada-Gomez and Bouillon, 2018). *†
Vitamin D is a fat-soluble vitamin, meaning it can be stored in fat, thus building up in the body. So, unlike some other vitamins, there is an upper limit of intake recommended for safety. The upper limit of vitamin D is 4000 IU for adults and children aged 9-18 years old, and 3000 IU of vitamin D for children aged 4-8 years old (Ross et al., 2011). If you are currently taking a Vitamin D supplement, we recommend checking the dose and contacting your healthcare provider before continuing supplementation to avoid reaching this upper limit.
Vitamin K2
Vitamin D also interacts with other nutrients in the body. Some studies suggest that taking vitamin K2 with vitamin D3 helps promote bone and immune health (Ushiroyama et al., 2002; Goddek, 2020). However, more research is still emerging, so check with your healthcare provider about what is appropriate for you based on your individual health needs.
Vitamin C
Have you ever heard that taking Vitamin C can help protect your body from pathogens and aid in quicker recovery? Well, if you have, you heard correctly! Vitamin C plays many roles in the body, and helping boost your immune system is one of the most critical roles. Unlike Vitamin D, Vitamin C is a water-soluble vitamin, so if you take more than your body can use, it’s more easily eliminated (Carr & Maggini, 2017).
Zinc
Just like Vitamin C, Zinc is also known for having a positive impact on immune health. When taken together with vitamin D, this trio can provide a comprehensive immune-boosting toolbox (Wintergerst et al., 2006).
With d.velop™ ImmunityPlus, you would be equipped with calcifediol that promotes optimal vitamin D levels quickly and efficiently, as well as vitamin C and zinc to strengthen your immune system further. *†
What if I am already taking a multivitamin or another Vitamin D supplement?
Suppose you are currently taking vitamin D or a supplement containing vitamin D. In that case, we recommend that you check the amount of vitamin D in those supplements if you plan to take them while taking d.velop™ vitamin D, d.velop™ ImmunityPlus, or d.velop™ Kids gummies.
We recommend that you consult with a healthcare professional before starting any dietary supplement products. The current recommended upper limit (UL) for vitamin D intake is 3000 IU for children aged 4-8, and 4000 IU for adults and children aged 9-18 (IOM, 2011). If you are unsure, it is always a good idea to check your vitamin D levels with our d.velop™ vitamin D test.
