Vitamin D and summer: everything you need to know

Should we take Vitamin D at all times, even in summer? With all the information available online, as I often say, you can get mixed up like a deck of cards! That's why I'm going to take a few minutes to clarify whether vitamin D supplementation is essential, even in summer.

The importance of vitamin D

Vitamin D is essential for many functions, including maintaining strong bones, supporting the immune system and promoting optimal muscle function. Usually synthesized by the skin through exposure to the sun's UVB rays, its production can be insufficient in regions where sun exposure is limited (like Quebec!) and where cold seasons reduce the time spent outdoors.

In short, the vitamin influences

Bone health: It keeps bones strong and healthy by helping to absorb calcium.

Immune system: It supports the body's defense system, helping to fight infections.

Muscle function: It promotes optimal muscle function, helping to maintain strength and balance.

Disease prevention: It helps reduce the risk of illnesses such as heart disease, diabetes and certain cancers.

Mental health: It can improve mental health by influencing neurotransmitters, helping to reduce the risk of depression.

Fertility: It promotes reproductive health by supporting ovarian function and sperm quality.

Types of supplements available

Vitamin D supplements are available in a variety of forms, including capsules, chewable tablets and liquid form. Capsules offer ease of use and precise dosing, ideal for facilitating consumption on a daily basis. On the other hand... Liquid forms are often preferred for faster, more effective absorption. Choose the form that best suits your daily routine and personal preferences!

In addition, certain foods rich in healthy fats, such as oily fish (salmon, mackerel) and vegetable oils, and taking vitamin K2 supplements, can help increase the body's absorption of vitamin D. In fact, there are several supplements that combine vitamin D and vitamin K2.

Eating vitamin D even in summer?

Finally, we come to the heart of the matter. In Quebec, even in summer, most people spend around 96% of their time indoors, which can significantly limit the sun exposure needed for natural vitamin D synthesis. That's why YES, it may still be worth taking a vitamin D supplement.

Also, it's important to note that vitamin D levels can vary considerably from one person to another, so it's essential to ask your doctor to take a blood test to determine whether or not you're really deficient, because we don't want to consume supplements unnecessarily!

Adapt your intake to the seasons

In summer, when sun exposure is more frequent, it may be wise to temporarily reduce supplement doses. On the other hand, in winter, when sun exposure is reduced and vitamin D levels are naturally lower, it's often advisable to double doses to maintain optimal levels.

In conclusion, even during the summer months in Quebec, vitamin D consumption can be beneficial to compensate for insufficient sun exposure and maintain optimal bone and immune health, especially if you're someone who often works indoors (office work or otherwise). But don't forget to ask for a blood test to set the record straight! On that note, I encourage you to enjoy the sun this summer, safely, while filling up on vitamins!
