When the seasons change, so do our health and wellness needs.

While many of us look forward to the summer months, it’s important to be mindful of the impact it can have on your health. In the summer, you’re exposed to stronger UV rays, higher temperatures, and more activities, like travelling. Alongside a healthy diet and fitness routine, certain vitamins and supplements can go a long way toward supporting your health and wellbeing.

That’s why we’ve rounded up some of our favourite vitamins and supplements to help you take care of yourself (and your family) this season.


Should I take vitamin D in the summer?

If vitamin D is known as the sunshine vitamin, don’t we get enough in the summer?

Yes, our bodies rely primarily on sunshine to produce vitamin D, an important vitamin for maintaining strong, healthy bones and teeth. But there are some cases where relying on the sun might not be enough.

The following factors may influence your body’s ability to produce vitamin D from the sun:1

  • Age: less is made by people 65+
  • Skin colour: less is made by darker skin because more melanin competes with UVB rays
    The amount of time you spend outside: you work mostly indoors
  • Sunscreen: You should still always wear sunscreen, but it also affects how much vitamin D your skin makes from the sun

In addition to vitamin D, we’ve covered the vitamins and supplements you should consider taking, depending on your needs, below!


What vitamins and supplements should I take in the summer?

If you wear sunscreen (which you should!)

Take a vitamin D 1000 IU supplement

We need sun protection just as much as we need vitamin D. Sunscreen is essential because it protects your skin from the sun’s UV rays. However, sunscreen can also inhibit the skin’s ability to produce an optimal amount of vitamin D from UV light. If you need more vitamin D support this summer, consider including a vitamin D supplement in your routine.

Vitamin D 1000IU
Taking 1 daily tablet of Sisu Vitamin D 1000 IU helps to maintain healthy immune function, and builds strong bones and teeth. It offers 1000 IU of vitamin D in a tiny, fast-dissolving tablet. And, it’s free from lactose, sweeteners, and added colours or flavours.
If you’re active

Take a B-vitamin and vitamin C supplement

Summer weather makes it easier to exercise outdoors but also makes it easier to get overheated and overtired. While playing sports and exercising this summer, support your energy and immune health with nutrients such as B-vitamins and vitamin C.

And don’t forget to drink plenty of water! Staying hydrated will help your body cool down as you lose more bodily fluids to sweat in the summer.

Just add water to benefit from B-vitamins for energy metabolism and 1000 mg of Ester-C® to help maintain immune function. It also contains electrolytes and antioxidants. Available in lemon-lime, wildberry, orange, and piña colada flavours!⁠
If you want to maintain healthy skin

Take a biotin supplement

Summer heat can do a number on your skin, from sweat to dryness to greater chances of a sunburn. That’s why it’s important to be proactive when it comes to your skin health and protection. Apply sunscreen daily, drink plenty of water, and take a skincare supplement that contains biotin. Also known as vitamin B7, biotin is an important nutrient that the body needs to metabolize fatty acids, which are the building blocks of healthy skin cells.5

Skin, Hair & Nails
Sisu Skin, Hair & Nails retains moisture and improves your skin’s hydration by combining skin-supporting ingredients like biotin, zinc, horsetail extract, Hyabest™ hyaluronic acid, and more.⁠⁠
If you have kids

Give them a vitamin C supplement

School may be out for the summer, but the immune system doesn’t take a vacation, especially younger immune systems. Whether you’re taking your kids on a trip or sending them to summer camp, it’s important to take steps to support their immune health. This includes:6

  • feeding them plenty of fruits and veggies
  • ensuring they get enough sleep
  • exercising as a family
  • encouraging regular hand-washing
  • helping them take their vitamins
U-Cubes Vitamin C Gummies
Sisu Vitamin C U-Cubes™ are an easy way to get your kids (even the picky-eaters!) to take their vitamins. These great-tasting vegan gummies provide immune system support. And they are naturally flavoured and free of artificial colours and sweeteners.⁠⁠
