Updated: Sep 16, 2025

Vitamin D is a great supplment to support hormone balance. This blog talks about Vitamin D, one of the top 5 supplements that women can take to support hormone balancing as recommended by Sue Mullinger of Your Nutrition, a Registered Nutritional Therapist and Health Coach.

When your hormones are out of sync, everything feels harder, from your mood to your sleep and even your skin. Sound familiar? Take a moment to read 'Using Vitamin D to Support Hormone Balance'. I hope you enjoy it.


In my blog 5 Top Hormone Balancing Supplements for Women, I shared my top five powerful supplements that can help bring your body back into harmony, and Vitamin D is one of them.


Vitamin D, often called the “sunshine vitamin,” is both a vitamin and a hormone essential for maintaining healthy hormone levels throughout your body. It’s part of a family of related compounds, with Vitamin D3 (cholecalciferol) being the form synthesized in your skin when exposed to sunlight.


Foods rich in Vitamin D3 include:

  • Eggs

  • Fatty fish (like salmon and mackerel)

  • Liver

  • Mushrooms

  • Fortified foods (such as orange juice or milk)


Another form, Vitamin D2 (ergocalciferol), is derived from fungi and is commonly used in supplements and food fortification.


Why Many Women Lack Vitamin D

Getting sufficient Vitamin D can be challenging, especially in places like the UK, where sunlight is scarce for much of the year. Spending time outdoors is a great way to boost your Vitamin D levels naturally. For fair or sensitive skin, 10–15 minutes of sun exposure daily is often enough, while darker skin tones may need 25–40 minutes from April to September.


Hormonal imbalances can also be a clue that your Vitamin D levels might be too low. Common symptoms of deficiency include:

  • Depression or low mood

  • Brain fog

  • Fatigue

  • Bone loss


How to Replenish Your Vitamin D Levels

If you suspect a deficiency, getting your levels checked is a great first step. A simple blood test from your doctor can help determine whether supplementation is needed.


When supplementing, look for Vitamin D3 (cholecalciferol), which is better absorbed by the body compared to Vitamin D2. A therapeutic dose of around 1,000 IU per day is a good starting point, though your specific needs may vary depending on factors like age, lifestyle, and current levels.


As a Functional Nutritionist, I can help you determine the right dosage and ensure your Vitamin D supplementation works in harmony with your body’s overall needs. Consistency is key - replenishing Vitamin D is a long-term commitment to feeling vibrant and balanced!
