Here’s what smart people know: your immune system needs more than just vitamin C. During winter months, your vitamin D levels plummet from lack of sunlight, weakening your first line of defence. Meanwhile, daily stress and exposure to germs depletes your vitamin C reserves.
This powerful combination gives your immune system both essential nutrients it needs to function normally, especially when you need it most.
Most people rely on vitamin C alone, but ignore their vitamin D status. If you spend time indoors, live through winter months, work in offices, or simply want to avoid sick days, you need both nutrients working together for optimal immune function.
Whether you’re a parent, student, or professional, you need a well-functioning immune system and vitamin C contributes to the normal function of the immune system.
Vitamin D3 is often called the “sunshine vitamin”. During winter months, shorter days and less sun make it nearly impossible to get adequate vitamin D levels naturally.
This combination contributes to normal function of immune system2 while contributing to the maintenance of normal bones and teeth¹.

4.9 / 5
Both vitamin D and vitamin C contribute to the normal function of the immune system. While vitamin C contributes to protection of cells from oxidative stress, vitamin D ensures your immune system can respond properly to threats.
Vitamin C contributes to the reduction of tiredness and fatigue and normal energy-yielding metabolism. Combined with vitamin D’s support for the normal function of the immune system, this helps you feel less tired even in the coldest months.
Vitamin D contributes to the maintenance of normal bones and teeth. Vitamin D also contributes to normal absorption and utilisation of calcium and phosphorus. Without adequate vitamin D3, your body can only absorb a fraction of the calcium you consume.
1000 mg of vitamin C contributes to protection of cells from oxidative stress, while 1000 IU of vitamin D3 contributes to the normal function of immune system, especially in winter, when you might not be getting enough sun.
Vitamin C is your classic immune vitamin, while vitamin D3 replaces what your body can’t produce during indoor living and darker months. Together, they provide excellent immune coverage.
Perfect for parents, office workers, students, travelers, or anyone who can’t afford sick days. One simple drink covers both your immediate and long-term immune needs.
The refreshing lemon flavour combined with fatigue-fighting vitamin C makes this a supplement you’ll actually look forward to taking.
