Make a batch of these Immune Boosting Smoothie Cubes with Elderberry Syrup for colds and flu, sinus infections, seasonal allergies, and general wellness. Each cube is jam-packed with ingredients specially selected for their immune-boosting capabilities.
Smoothie cubes are a great way to add some extra nutrition into your smoothies by tapping into nature’s farm-acy to stay healthy and strong, so let’s break down each ingredient and its role in boosting the immune system.
Black Elderberry Syrup For Colds – An Age-Old Remedy
One of the oldest natural remedies for cold, flu, and sinus infections is a syrup made from elderberries. Black elderberries (Sambucus nigra) are a small, firm berry that are a deep, almost-black purple color that grow in Europe and parts of North America.
Like other berries and jewel-toned fruits, they contain vitamin C, anthocyanins, and other antioxidants. Vitamin C is important for a strong, healthy immune system. The other properties in elderberries may have anti-inflammatory benefits, including the reduction of swelling in the mucus membranes that are commonly associated with cold and flu.

The Sunshine Vitamin: Vitamin D₃
Vitamin D₃ can be synthesized by the human body with sufficient UV-B exposure via the sun; it is often called the “Sunshine Vitamin.” Nowadays a lot of us don’t get outside as often as we should or as time permits. As such, it becomes important to supplement D₃ to prevent a deficiency. Vitamin D₃ is important in preventing certain autoimmune diseases, osteoporosis (especially in women during menopause; it aids in calcium absorption), and even some cancers.
It’s fairly common for someone to be feeling fatigued and just generally under-the-weather. One can go to the doctor, and blood tests can come back and show low levels of vitamin D. In short, deficiencies are common, so it doesn’t hurt to supplement a bit.
Oleuropein from Olive Leaf Extract
Olive leaf extract is something you may not have heard about. It’s a liquid supplement derived from Olea europaea olive leaves and combined with benign carrier liquids such as glycerine and water. Suggested use for adults is 1 tablespoon per day. It should be mixed with water or juice, or blended into a smoothie, and should not be given to children unless a medical provider has directed to use it.
Olive oil and olive leaves have been used for centuries for medicinal purposes. Olive leaves contain the powerful antioxidant called Oleuropein and well as a wide range of polyphenols. Oleuropein helps support the immune response and can also help with seasonal wellness.
Blackberries and Blueberries
Blueberries and blackberries both contain anthocyanin, a powerful antioxidant that gives berries their beautiful red, purple, and blue hues. Berries are also high in vitamin C, which helps to keep the immune system functioning properly. Vitamin C deficiency is rare these days, but can happen if fresh fruits and veggies aren’t part of the diet.
Because vitamin C, also known as ascorbic acid, is water-soluble, it is excreted regularly through the urinary tract, so it’s important to consume foods high in vitamin C. Supplementation can help, but studies have shown that food sources are the best, with a supplement or enriched food (such as rice and other cereals) coming in second.
