1. Vitamin D

Vitamin D, referred to as the ‘sunshine vitamin’, plays a crucial role in strengthening bones and for the proper functioning of the immune system and young women in their 20s and 30s should ensure that they take adequate amounts of the vitamin.

Specifically, this nutrient can assist your body in efficiently incorporating calcium and phosphorus, both of which play indispensable roles in the creation of sturdy bones. In these years it is especially important to pay much attention to bones as the body is really busy trying to achieve maximum bone density and seems to reach its goal in the mid-late twenties.

Then after, the bone density decreases, so it requires vitamin D to maintain the healthy bone density you need all your life.

It does not just do that! The role played by this vitamin is so much greater! It also greatly assists your immune system to help manage the body’s defense against ailments as well as diseases.

The lack of vitamin D may be because you do not step out much, your skin does not get much sun exposure because you work inside a building most of the time, or you always apply sunblock whenever you go out to get some sun tan.

To maintain an adequate amount of vitamin D, take foods that contain it such as fatty fish, egg yolks, and dairy products with added vitamin D. Taking a good vitamin D supplement can also aid in enhancing one's intake of this noble nutrient.

Therefore, by ensuring that you have enough vitamin D in your diet and in the supplements that you take, you not only strengthen your bones and immune response but also the entire body.

Despite the instances, it is a very small step with significant gains, and therefore it should be practiced by women in their 20s and 30s. Stay healthy and vibrant!

• Talk to Your Doctor: Before starting any supplement, have a chat with your doctor. They'll give you advice that fits your health history and current needs.

• Check for Allergies: Look at supplement labels for things like soy, dairy, or gluten if you have allergies or sensitivities. Choose hypoallergenic options if needed.
• Special Health Conditions: Certain health issues mean you need to be careful with specific supplements. For example, women with kidney issues should watch their intake of minerals like potassium and magnesium.
