6 Vitamins & Supplements You May Want This Winter

Key Takeaways:

  • Vitamin C, D, and zinc are essential for supporting your immune system during the winter months.*
  • Winter can also do a number on your skin and your energy. Collagen Hyaluronic Acid Complex can support glowing skin, while B-vitamins support daily energy.*

Your closet isn’t the only thing that needs switching up in the winter — your vitamin and supplement routine might need a refresh too.

Changing times can mean a change in health needs. Your immune system requires support, your skin may feel dryer, you may have less energy, and even your joints may be giving you occasional issues.

Don’t worry, we’ve put together a comprehensive list of vitamins and supplements that may help support your health this winter, so that you can feel your best.




1. Vitamin C

When you’re considering vitamins to support your immune system, vitamin C is probably one of the first vitamins you think of — and for good reason.

Vitamin C is a powerful antioxidant that can neutralize harmful free radicals.2 It also supports the functioning of white blood cells, which are important components of a healthy immune system.3

Many foods, especially fruits and vegetables, are rich in vitamin C. However, the easiest way to ensure you’re getting your daily dose of vitamin C is to take a vitamin C supplement.

Here are a few that might fit your lifestyle:

Vitamin C supplements for the winter


Ester-C® is vitamin C, but better. Unlike regular vitamin C, Ester-C® stays in white blood cells for up to 24 hours, and is non-acidic and gentle on the stomach.*

One capsule taken daily supports upper respiratory health, harnesses the power of antioxidants to help fight against free radicals, and delivers advanced immune support.*

Ultra Potency Vitamin C Gummies

If you don’t like swallowing pills, this supplement is for you. Solgar® Ultra Potency Vitamin C Gummies pack 1000 mg of vitamin C into just one gummy. It has the highest potency in a single gummy among major brands in the Natural Channel.^


If you’re looking for a supplement that contains vitamin C, D, and zinc, look no further than Solgar® Ester-C® Plus Immune Complex.

This unique supplement gives you the ultimate combination of immune-supporting ingredients, including Ester-C®, vitamin D, and zinc, as well as immune-supporting herbal ingredients elderberry, astragalus, and echinacea.* It even includes magnesium and vitamins B6, B12, and pantothenic acid.

Its unique softgel form ensures quick absorption, and it’s non-GMO, gluten-free, and dairy-free.


2. Vitamin D

Vitamin D is critical for immune function. The body’s main source of vitamin D is usually the sun’s ultraviolet B rays, hence the nickname, “the sunshine vitamin.” However, if you live somewhere where sunlight is limited, or you don’t spend much time outdoors, you may be at risk of low levels of vitamin D.4

If you’re unsure if you’re getting enough vitamin D from the sun, consider opting for a vitamin D supplement instead.

From gummies to vegan softgels, here are a few that might work for you:

One softgel taken daily helps maintain a healthy immune system, strong bones and teeth, and optimal nerve and muscle function.* Our convenient, oil-based softgels are easy to swallow and absorb.

Ultra Potency Vitamin D3 Gummies

This completely vegan vitamin D3 supplement is made with naturally & responsibly-sourced lichen. Each serving helps maintain strong bones and teeth and a healthy immune system, and supports nerve and muscle function.*


3. Zinc

Zinc is essential for many bodily functions. It is a major player in the creation of DNA, growth of cells, building proteins, and supporting the immune system.5

Zinc plays a significant role in many aspects of the immune system. It helps the normal growth and function of cells in your innate immune system, including T and B cells, which help your body protect against foreign substances (antigens).6

Because zinc supports the growth and normal functioning of immune cells, even a mild or moderate deficiency can slow down the activity of lymphocytes, neutrophils, and macrophages.7

Let’s take a look at some of the best zinc supplements to take in the winter:

Vitamins & supplements for skin health in the winter

If you find that your skin is more dry or problematic during the winter, you’re not alone. According to the American Academy of Dermatology, cold air can make your skin feel dry and itchy, and can make fine lines and wrinkles more noticeable.8

Thankfully, there are supplements that help support healthy, glowing skin:


4. Collagen & Hyaluronic Acid


This best-selling formula boosts skin collagen in just 12 weeks, helps soften the appearance of wrinkles, increases skin elasticity, and supports healthy, glowing skin.*‡ The collagen source is completely hormone- and antibiotic-free.


5. Evening Primrose Oil


This supplement is cold-pressed from the seeds of the evening primrose plant and contains the unsaturated fatty acids GLA and linoleic acid. One softgel, taken daily, supports healthy skin and can help with occasionally dry skin.*


Vitamins & supplements for winter fatigue

Short days, long nights, cold temperatures, and more time spent inside can make you feel more tired and sluggish than usual.

Shorter daylight hours also can cause the brain to create more of the sleep-regulating hormone melatonin, which may make you feel more tired during the winter months.9


6. B-vitamins

B-vitamins can be a great way to support daily energy.* Let’s take a look at a few B-vitamin supplements to take in the winter:

B-vitamin supplements for the winter


Just one gummy a day delivers 1500 mcg of vitamin B12 — that’s the highest potency in a single gummy.^ Each serving helps support energy metabolism.† With 2 g of sugar per serving, you can feel good about choosing gummies over pills.
