When Progesterone Isn’t Right: What to Add, What to Eat, and What the Data Tells Us

If you’ve been feeling wired but tired, anxious for no clear reason, waking at 3am with your mind racing, or carrying weight around your middle that won’t shift, progesterone might be the missing piece of your puzzle.

Not oestrogen. Not thyroid. Not stress (well, not just stress).

Progesterone. The hormone that quietens your nervous system, steadies your mood, supports your sleep, and keeps oestrogen in check. And in perimenopause, it’s the first hormone to decline.

Often years before anything else shifts.

Why Progesterone Drops First

Progesterone is produced after ovulation. As cycles become more irregular in perimenopause, ovulation becomes less consistent, and without ovulation, there’s no corpus luteum, and without that, there’s very little progesterone.

This is why so many women in their late 30s and early 40s start feeling “off”, anxious, puffy, sleepless, emotionally volatile, even when their oestrogen levels still look normal on a standard blood test.

The problem isn’t always how much oestrogen you have. It’s how much progesterone you have relative to it.

This is called oestrogen dominance. And it’s incredibly common, incredibly underdiagnosed, and absolutely fixable.

How Do You Know if Your Progesterone Is Low?

Symptoms are a starting point. But symptoms alone don’t tell the full picture. Here’s where testing becomes your superpower.

The Mira Monitor: I use this with clients to track FSH and LH in real time. It’s a home urine monitor that gives you actual hormone data across your cycle, not just a snapshot. When we look at the pattern together, we can see exactly where the hormonal rhythm is breaking down, and whether ovulation is actually happening.

The DUTCH Test: This is my gold standard for a comprehensive hormonal picture. It doesn’t just measure hormone levels; it shows how your body is metabolising them. Low progesterone, elevated oestrogen metabolites, adrenal dysfunction, it’s all there.

Data removes the guesswork. When a client can see what’s happening in her own body, everything changes, her understanding, her motivation, and her results.

What to Add: Supporting Progesterone Naturally

There are several ways to support progesterone levels, depending on where you are in your journey.

1. Dr Anna Cabeca’s Pura Balance Cream

This is a bio-identical progesterone and pregnenolone cream derived from wild yam, formulated by one of the world’s leading women’s health physicians. Unlike synthetic progestins, which can create toxic metabolic by-products and worsen hormonal imbalances, bio-identical progesterone is structurally identical to the hormone your body makes.

Pregnenolone, also in this formula, is the “mother hormone” that declines with age and is essential for bone health, mood, memory, and graceful ageing.

For perimenopausal women: use days 14–28 of your cycle. For post-menopausal: days 1–25 of each month.

 2. Vitex (Agnus Castus)

A well-researched herb that works on the pituitary gland to support the hormonal signalling that encourages progesterone production. Most effective in perimenopause when ovulation is still occurring.

3. Zinc and Vitamin B6

Both essential cofactors for progesterone synthesis. If your diet is low in these, or your gut isn’t absorbing them well, your progesterone will suffer. This is one reason I always look at the full picture, including gut health.

4. Reduce Xenoestrogens

Plastic food containers, conventional beauty products, and synthetic fragrances, these all contain oestrogen-mimicking compounds that worsen the progesterone-oestrogen imbalance. Swapping these out is low-effort, high-impact.

What to Eat: Blood Sugar is Everything

Here’s something most women don’t know: your nervous system and your progesterone are deeply connected through blood sugar.

When blood sugar spikes and crashes, from skipping meals, eating ultra-processed foods, or not getting enough protein, your body releases cortisol to compensate. Cortisol and progesterone compete for the same receptor sites. High cortisol means low progesterone availability, even if your levels look okay on paper.

Prioritise these foods to support progesterone:

Protein at every meal: eggs, fish, chicken, legumes. Aim for 25–30g per meal to stabilise blood sugar and support hormone synthesis.

Healthy fats: avocado, olive oil, oily fish, nuts and seeds. Hormones are made from fat. Don’t fear it.

Magnesium-rich foods: dark leafy greens, pumpkin seeds, dark chocolate. Magnesium supports progesterone production and calms the nervous system.

Complex carbohydrates: sweet potato, oats, brown rice. These provide a slow, steady glucose release that keeps cortisol in check.

Zinc-rich foods: pumpkin seeds, shellfish, red meat, chickpeas.

What to reduce: ultra-processed foods, refined sugar, alcohol, and caffeine on an empty stomach. All of these spike cortisol and worsen the hormonal picture.

What the Data Tells Us

I’ve worked with women who have spent years being told their hormones are “normal” only to discover through functional testing that their progesterone was chronically low, their oestrogen metabolites were poorly cleared, and their adrenals were running on empty.

The data tells a different story to the symptom diary. And when we act on it, combining targeted supplementation, blood sugar support, stress regulation, and where appropriate, bio-identical hormone support like the Pura Balance Cream, women feel the difference.

Not in a subtle, “maybe it’s working” way.

In a “I actually feel good” way.

That’s what targeted, intelligent support looks like.
