Top 7 Best Cortisol Supplements for Women in 2025
Ashwagandha
This is an herb that has been known for many years for its adaptogenic properties in the body to may help the body adapt to occasional stress and support balanced cortisol levels over time (especially in the adrenal glands).
This may support stress resilience and overall vitality, physical strength, and immunity (Alexander Panossian, 2017).
In the thread Ashwagandha used for low cortisol? There are two distinct opinions on the effectiveness of this herb in stabilizing cortisol.*
Some comments agree with the user opinion that ashwagandha does not directly stabilize cortisol but rather makes the receptor more sensitive to increase GABA activity so as not to cause stress.*
On the contrary, another user found that ashwagandha lowers cortisol too much, leading to many abnormal manifestations in the body*.
Magnesium
The cause of stress and insomnia can come from a nutritional deficiency, more specifically magnesium. Because this mineral participates directly in many biological activities in the body, thereby supporting hormonal balance (including cortisol), which may promote relaxation, alertness, and healthy sleep patterns.
Accordingly, the amount of magnesium needed to supplement daily is 400 - 420 mg (for men) and 310 - 320 mg (for women) - this is the recommended level from foods and functional foods [2].
L-theanine
L-theanine is a compound found in tea (especially green tea) and mushrooms. With the ability to effectively calm the nervous system, after just a cup of tea or eating mushrooms properly, may promote a sense of calm and support mental clarity without causing drowsiness.
But unlike caffeine, L-theanine in tea/mushrooms has the ability to maintain a stable, long-term effect instead of flaring up and then decreasing sharply [3, 4].
This information has caused quite a bit of controversy in a Reddit discussion. According to statistics, the claim that L-theanine actually stabilizes cortisol is as follows *:
Omega-3 fatty acids
Omega-3 fatty acids are commonly known for their ability to build brain cells and a healthy nervous system. This helps you become more alert and remember information better.
Not only that, this fatty acid has been shown to have a positive effect in stabilizing cortisol levels in the body if someone feels overly stressed. This reduces the risk of cell inflammation caused by excessive cortisol activity [5,6].
Vitamin C
Vitamin C is commonly known for its effective antioxidant and anti-inflammatory properties. Thanks to that, it can improve people's natural resistance to harmful environmental factors.
In addition, this vitamin is considered a very good "companion" for those who often experience stress, which occurs when cortisol levels are constantly increasing (Paul E Marik, 2020).
However, humans cannot produce vitamin C themselves and must supplement it through food or functional foods at a dose of 75 mg/day (for women) and 90 mg/day (for men) [8].
Rhodiola rosea
This is an herb that has been used in traditional medicine for thousands of years and has recently gained attention for its ability to support emotional balance and stress resilience.
One study also found that, when used properly, Rhodiola rosea may help promote a stable mood and improve the body’s response to mental fatigue thanks to the strong “adaptability”* of more than 140 compounds isolated from the roots and rhizomes [9].
(*) Simply put, adaptogens are a group of natural substances, mostly of plant origin, that help the body cope with stress and maintain internal hormonal balance (homeostasis) naturally, maintaining long-term stability.
Ginseng
Ginseng is another well-known adaptogen that may support healthy stress responses. Some studies suggest it may influence the hypothalamus-pituitary-adrenal (HPA) axis, which plays a key role in cortisol production and regulation.
While ginseng may not offer immediate effects, it has been noted for its long-term support of overall well-being [10].
If there is a moderate amount of ginseng, the activity in these organs is stabilized, which may help modulate cortisol secretion as part of a balanced stress response.
In addition, ginseng is a fairly good adaptogen like Rhodiola rosea, so in general, it may not have an immediate cortisol-stabilizing effect, but it is long-lasting, giving you a feeling of comfort.
How To Choose The Best Cortisol Supplement for Women
Ingredient
You should prioritize using product ingredients that are safe and able to support cortisol stabilization. For example, Ashwagandha, Rhodiola Rosea, Holy Basil, Magnesium, L-Theanine, Vitamin B6/B12, Omega-3, Phosphatidylserine, Relora, GABA,...
This ensures that the expected results may include support for natural cortisol balance, when used as directed, with few unwanted side effects.
Formulation
Don't forget to consider whether the product uses technology to improve absorption. For example, liposomes or chelated minerals. Or any substances that you are allergic to, such as milk, soy,... as well as ingredients that have strong stimulant properties, such as caffeine, yohimbine,...
Because, although these ingredients have the ability to stabilize cortisol quickly, they are accompanied by some unwanted side effects such as "disrupting" hormonal balance, increasing anxiety,...
Form

As for gummies, the product is suitable for users who are not familiar with the original taste of the ingredients and want to find a sweet, easy-to-use type.
Purity

Therefore, you should carefully research whether the nutritional formula can meet your desired purposes or not. And the product limits adding too many unnecessary fillers.
Brands & Certifications
