Progesterone: Finding The Right Dose For Your Body | with Angela Hywood
Progesterone is often called the "calming" or "balancing" hormone. For many women, it can help with sleep, mood, and cycle regulation.
But in clinical practice, progesterone is not a one-size-fits-all treatment.
How it works depends on:
The most important message is this: More progesterone is not always better.
The right amount, in the right form, for the right reason, and at the right time is what makes the difference.
Why Do Women Use Progesterone
Progesterone may be prescribed for several different reasons. The dose and delivery method will change depending on the goal.
1. TO PROTECT THE UTERUS (WHEN USING OESTROGEN THERAPY)
If you are taking estrogen, progesterone is essential to protect the lining of the uterus.
Without progesterone, the lining can continue to grow, which over time can increase the risk of abnormal thickening or, in some cases, cancer.
Typical doses:
This is about safety, not just symptom relief.
2. FOR FERTILITY OR IVF SUPPORT
Progesterone plays a key role in helping an embryo implant and supporting early pregnancy.
In this situation, progesterone is often given in higher doses, and usually through vaginal or injectable forms. These methods deliver the hormone directly to the uterus.
3. FOR SYMPTOMS LIKE POOR SLEEP, ANXIETY OR PMS
Lower doses of progesterone are often used to support the nervous system.
Many women notice:
This is one of the most common and helpful uses of progesterone.
Why Progesterone Can Feel So Calming
Progesterone does more than support reproduction. It also has important effects on the brain and nervous system.
When progesterone is taken by mouth, the body converts some of it into a naturally calming substance called allopregnanolone. This compound works on the brain's main calming pathway, known as the GABA system, which plays a central role in regulating sleep, anxiety, mood, and the body's stress response.
At the right dose, women often experience:
But if the dose is too high for your body, the opposite can happen.
You may notice:
This does not mean progesterone is wrong for you. It usually means the dose or form needs adjusting.
Not All Progesterone Is the Same
The way progesterone is taken changes how it behaves in the body.
ORAL PROGESTERONE (CAPSULES)

VAGINAL PROGESTERONE

Possible drawbacks:
PROGESTERONE CREAMS
These are popular because they are easy to use. However, they can be unpredictable.
Important to know:
This is why medical guidance is important when you are using progesterone long term.
A Common Myth Busted: "Wild Yam Cream" Is Not Progesterone
This is one of the most frequent misconceptions I see in clinical practice.
Many products marketed as wild yam cream, often purchased online, are promoted as natural progesterone and are widely used by women, but they often contain actual progesterone, not herbs.
WHY WILD YAM CREAM DOES NOT RAISE PROGESTERONE
Wild yam contains a plant compound called diosgenin. In a laboratory, scientists can convert diosgenin into progesterone. This scientific fact is what created the myth.
However, Your body cannot make this conversion. You do not have the enzymes required to turn wild yam into progesterone.
So, there is no point rubbing wild yam cream onto your skin in the hope that your progesterone will improve.
Progesterone vs Synthetic Progestins
These are often confused, but they are different.
Progesterone (bioidentical)
Progestins (synthetic)
Both have a place in medicine. Your practitioner will choose the most appropriate option for your situation.
When Progesterone Is Too Much
Higher doses are sometimes necessary, especially in fertility treatment. Outside of this situation, if the dose is higher than your body needs, you may notice changes.
Possible signs include:
These symptoms are not uncommon and can usually be improved by adjusting the dose or timing.
The Bottom Line
Progesterone is a powerful and helpful hormone when used correctly.
It can support:
But it works best when treatment is individualised.
The right questions to ask are:
Not all GPs have additional postgraduate training in women's health, perimenopause, and menopause, so it is reasonable to ask about their specific expertise in this area.
A Gentle Reminder
If you are using progesterone, regular review with your healthcare practitioner is important. Small adjustments in dose, timing, or delivery method can make a significant difference in how you feel.
Hormone therapy should always be guided, monitored, and tailored to your needs and physiology.
