Buy Immune Support & Immune System Supplements: Vitamin C, D3, Zinc and Herbs

Especially in autumn and winter, many people choose vitamin C, vitamin D and zinc. Health claims about the immune system are permitted for a number of vitamins and minerals: vitamin C, vitamin D, zinc, selenium and copper each contribute to the normal functioning of the immune system. Vitamin C also contributes to the reduction of tiredness and fatigue.

In this collection you will find both individual ingredients and complete formulas. Think of the LUTO Immunity Gummies with vitamin C, echinacea, elderberry and propolis, the Immune Complex by Vit4ever with echinacea and zinc, Immunity Essentials by German Elite Nutrition, echinacea by Swanson and Vit4ever, olive leaf extract, propolis, OPC grape seed extract (alone or with vitamin C), buffered vitamin C, vitamin D3 with K2 by Now Foods and the Go Immune effervescent tablets by SiS for athletes. This way you can choose between capsules, tablets, effervescent tablets, gummies and drops.

What can you find in this collection?

This collection contains vitamins and minerals such as vitamin C, vitamin D and zinc, for which health claims about the normal functioning of the immune system are permitted, and on the other hand, plant extracts and bee products such as echinacea, olive leaf, elderberry and propolis. The immune claims on this page apply exclusively to the mentioned vitamins and minerals, not to the herbs and bee products. Some products contain a single ingredient, while others combine multiple ingredients in a formula.

Which vitamins and minerals contribute to the normal functioning of the immune system?

For a number of nutrients, a health claim is permitted about the normal functioning of the immune system: vitamin C, vitamin D, vitamin A, vitamin B6, folic acid, vitamin B12, zinc, selenium, copper and iron. Vitamin C, zinc, selenium and copper also contribute to the protection of cells against oxidative stress. In this collection you will find a number of these nutrients individually (such as buffered vitamin C or vitamin D3) and as part of combination products.

A healthy foundation

A healthy lifestyle consists of varied eating, sufficient sleep, regular exercise and attention to relaxation. From a nutritional perspective, vitamin C, vitamin D and zinc contribute to the normal functioning of the immune system. If you want to supplement your daily intake, you will find supplements with these nutrients in this collection. A supplement is a supplement to and not a replacement for a varied, balanced diet and a healthy lifestyle.

What are vitamin C, D and zinc found in?

A varied diet provides many of these nutrients. Vegetables and fruit such as peppers, citrus fruits, kiwi and berries are well-known sources of vitamin C. Zinc can be obtained from nuts, seeds, whole grain products, legumes and meat, while fatty fish and eggs naturally contain vitamin D. Those who want to supplement their intake from food will find supplements with the same nutrients in this collection.

Which supplement is suitable for which season?

The choice depends mainly on your situation and the time of year. In autumn and winter, when there is less daylight, many people choose vitamin D3, because the production through the skin is lower then; vitamin C and zinc are popular all year round. Athletes often choose effervescent tablets such as SiS Go Immune with vitamin C and minerals. In spring and summer, you can choose a lower dosage or individual nutrients if desired. Always follow the recommended daily portion on the packaging for every product.

Echinacea, olive leaf, elderberry and propolis: traditional ingredients

In addition to vitamins and minerals, you will find a number of plant-based classics in this collection. Echinacea purpurea (coneflower) is a plant from North America that has been used as a herbal extract for generations. Olive leaf extract comes from the leaves of the olive tree and is standardized to oleuropein. Elderberry is a dark purple berry that is widely processed into syrups and gummies, and propolis is a resinous natural product that bees collect. There are currently no permitted health claims for these ingredients; we therefore describe them without efficacy claims. When choosing, pay attention to the extract ratio, standardization and the dosage per daily portion.

What is OPC grape seed extract?

OPC stands for oligomeric proanthocyanidins, plant substances from grape seeds. In this collection you will find OPC as a standalone extract and combined with natural vitamin C from acerola. For the vitamin C in that combination, the claim applies that vitamin C contributes to the normal formation of collagen for the normal functioning of the skin, blood vessels and gums. For OPC itself, there are no permitted health claims; when purchasing, mainly look at the OPC content per capsule.

Capsules, tablets, effervescent tablets, gummies or drops?

The choice of a form is mainly practical. Capsules and tablets are compact and easy to dose. Effervescent tablets, such as SiS Go Immune, dissolve in water and combine vitamin C with minerals. Gummies are a tasty alternative if you do not like swallowing pills, for example the LUTO Immunity Gummies with red fruit flavor. Drops, such as vitamin D3 with K2 for children, are flexible to dose and suitable for those who have difficulty swallowing.

Dosage: how much do you take per day?

The dosage varies greatly per product and per ingredient. For vitamin C, you often see 500 to 1000 mg per day, for vitamin D3 dosages in micrograms or IU, and for herbal extracts, the daily dose depends on the extract strength. Combination products usually have a daily portion of one or two capsules. Always follow the directions for use and the recommended daily portion on the packaging.

Who are these supplements suitable for?

This collection is here for anyone who wants to supplement their daily intake of vitamins and minerals, for example in the winter months. Many products are vegan or vegetarian; propolis and some gummies are an exception to this, so check the label. If you use medication, are pregnant or breastfeeding, consult a doctor or pharmacist first. A supplement is not a replacement for a varied, balanced diet and a healthy lifestyle.

What to look for when buying?

First look at the ingredient and the dosage per daily portion: is the amount of vitamin C, D or zinc clearly stated on the label, and for herbal extracts, the extract ratio and standardization? Then check the package size in relation to the daily dose, so you know how long one jar will last. Finally, pay attention to additives: many products in this collection are free from gluten, lactose and unnecessary fillers, and there are plenty of vegan options.
