Key findings from a 12-week clinical study:
- Depression and anxiety scores improved significantly.
- Testosterone levels and inflammation markers decreased.
- Antioxidant levels increased, supporting overall health.
This combination works by:
- Supporting the gut-brain connection to regulate mood.
- Reducing inflammation and balancing hormones.
- Enhancing serotonin and dopamine production.
For women with PCOS, addressing mental health is critical. Adding vitamin D and probiotics to treatment plans offers a science-backed way to improve mood, reduce stress, and manage symptoms. Telehealth services now make these treatments more accessible, offering personalized care plans and direct-to-home delivery.
Best PCOS supplements (what I take in 2023)
Research on Vitamin D and Probiotics for PCOS
Recent studies have been shedding light on the connection between gut health and mental health in women with PCOS, with a particular focus on the role of vitamin D and probiotics. Evidence suggests that these supplements may help improve both metabolic and mental health, offering hope for women managing PCOS-related depression and anxiety.
Clinical Studies on Vitamin D and Probiotics for PCOS
One notable study conducted at the Naghavi Clinic in Kashan, Iran, involved 60 women with PCOS aged 18–40 years. This 12-week randomized, double-blind, placebo-controlled trial divided participants into two groups. The intervention group received 50,000 IU of vitamin D every two weeks and 8 × 10⁹ CFU/day of a probiotic blend containing Lactobacillus acidophilus, Bifidobacterium bifidum, Lactobacillus reuteri, and Lactobacillus fermentum (each at 2 × 10⁹ CFU/g). The control group received a placebo.
The results were promising, showing significant improvements in mental health scores for the intervention group:
- Beck Depression Inventory (BDI): Improved by a mean difference of -0.58 (P = 0.04)
- General Health Questionnaire (GHQ): Improved by -0.93 (P = 0.03)
- Depression, Anxiety and Stress Scale (DASS): Improved by -0.90 (P = 0.02)
"Overall, the co-administration of vitamin D and probiotic for 12 weeks to women with PCOS had beneficial effects on mental health parameters, serum total testosterone, hirsutism, hs-CRP, plasma TAC, GSH and MDA levels." – Vahidreza Ostadmohammadi et al., Kashan University of Medical Sciences
Beyond mental health, the study also observed metabolic benefits. Total testosterone levels dropped by -0.19 ng/mL, hs-CRP levels (a marker of inflammation) decreased by -0.67 mg/L, while plasma TAC (Total Antioxidant Capacity) and GSH (Glutathione) levels increased by 82.81 mmol/L and 40.42 μmol/L, respectively (all P < 0.001 or P = 0.02).
These findings align with broader research showing that vitamin D deficiency is common in women with PCOS and is linked to mood disorders like major depressive disorder and seasonal affective disorder. The probiotics used in this study were selected for their ability to influence mental health by regulating neurotransmitters such as GABA and serotonin.
Why Use Vitamin D and Probiotics Together?
The combined use of vitamin D and probiotics appears to create a stronger effect than using either supplement alone. This synergy addresses several key factors that contribute to PCOS-related mental health challenges.
Boosting Vitamin D Activity:
Probiotics play a role in increasing vitamin D levels in the body and enhancing vitamin D receptor (VDR) expression. This boosts the vitamin's effectiveness in supporting brain function, immune regulation, and neuroprotection.
"Probiotics can not only reduce oxidative stress, hyperandrogenism, and inflammation, but also demonstrate a synergistic effect with vitamin D by enhancing VDR expression." – Ya Han et al., Heilongjiang University of Chinese Medicine
Reducing Inflammation:
Both vitamin D and probiotics target inflammation, but through different pathways. Vitamin D helps regulate the immune system and increases neurotransmitters like norepinephrine and dopamine by up-regulating tyrosine hydroxylase gene expression. Probiotics, on the other hand, reduce systemic inflammation via the gut-brain axis and promote neurotransmitter production.
Supporting the Gut-Brain Axis:
This combined approach directly addresses the microbiota-gut-brain axis, which influences both mental and metabolic health in PCOS. By improving gut health, this therapy can alleviate mood disorders and enhance overall well-being.
Balancing Hormones:
Hyperandrogenism, a hallmark of PCOS, is better managed with the combined use of probiotics and vitamin D. Probiotics improve insulin sensitivity and balance gut microflora, while vitamin D regulates enzymes involved in steroid hormone production. Together, they help lower testosterone levels, reduce hirsutism, and improve body image, which can have a positive impact on mental health.
"Therefore, co-supplementation with probiotics and vitamin D has been shown to provide significant health benefits in terms of mental health, serum total testosterone, and oxidative stress parameters." – Ya Han et al., Heilongjiang University of Chinese Medicine
These findings highlight the potential of this combined therapy as a comprehensive treatment option for women with PCOS. By addressing both physical and psychological symptoms, vitamin D and probiotics could play a key role in personalized PCOS management strategies. For women experiencing PCOS, checking vitamin D levels and incorporating targeted probiotics may offer a practical, evidence-backed approach to improving overall health.
Mental Health Benefits of Vitamin D and Probiotics
Vitamin D and probiotics have shown a strong positive impact on mental health for women with PCOS. In a recent 12-week study, participants reported noticeable improvements in depression, anxiety, and stress levels. Compared to a placebo group, these women experienced measurable changes, including reductions in key mental health scores: Beck Depression Inventory (BDI) by –0.58 (P = 0.04), General Health Questionnaire (GHQ) by –0.93 (P = 0.03), and Depression, Anxiety, and Stress Scale (DASS) by –0.90 (P = 0.02).
These effects are largely attributed to the neuroprotective qualities of vitamin D and the role probiotics play in supporting the gut-brain connection. Together, their anti-inflammatory and antioxidant properties create a powerful, combined effect.
"Their combined immunomodulatory, antioxidant, and anti-inflammatory actions enhance mental health parameters." – Vahidreza Ostadmohammadi et al., Researchers, Kashan University of Medical Sciences
This improvement in mental health paves the way for exploring additional hormonal and physical benefits.
Other Hormonal and Physical Benefits
The benefits of pairing vitamin D with probiotics extend beyond mental health. This combination has been shown to improve hormone levels, reduce inflammation, and enhance overall antioxidant capacity. For instance, in the same study, total antioxidant capacity (TAC) increased by 82.81 mmol/L (P < 0.001), total glutathione (GSH) levels rose by 40.42 μmol/L (P = 0.02), and malondialdehyde (MDA) levels dropped by 0.25 μmol/L (P = 0.001). These changes not only support mood improvement but also help regulate hormonal balance in women with PCOS.
"Probiotics can not only reduce oxidative stress, hyperandrogenism, and inflammation, but also demonstrate a synergistic effect with vitamin D by enhancing VDR expression." – Ya Han et al., Frontiers in Endocrinology
For women looking to manage the mental health challenges of PCOS, these findings underline the potential of targeted nutritional strategies to deliver meaningful results in just a few weeks. By addressing both mental and physical aspects of health, vitamin D and probiotics offer a promising avenue for improving overall well-being.

How Gut Health Affects Mental Health in PCOS
The link between the gut and brain goes far beyond digestion. For women dealing with PCOS, this connection is particularly important, as an imbalanced gut microbiome can influence mood and anxiety levels.
Brain Chemical Regulation and Mental Health
Your gut plays a key role in producing neurotransmitters. In fact, about 95% of the body’s serotonin is made in the gut, which is why it’s often referred to as the "second brain".
"Gut bacteria both produce and respond to the same neurochemicals - such as GABA, serotonin, norepinephrine, dopamine, acetylcholine and melatonin - that the brain uses to regulate mood and cognition." – Mark Lyte, PhD, Texas Tech University Health Sciences Center
For women with PCOS, this balance is disrupted. Lower levels of serotonin and dopamine are frequently observed, which may not only impair reproductive hormone regulation but also contribute to mood swings and other emotional challenges. Preclinical studies back this up: in 2011, anxiety-prone mice treated with Lactobacillus rhamnosus for 28 days showed increased GABA receptor expression. Similarly, another study found that a 10-day course of Bifidobacterium longum helped mice with gut inflammation return to normal behavior.
"The vagus nerve also influences mood by modulating serotonin (5-HT) and GABA, improving common anxiety and depression symptoms in PCOS patients." – Caihong Li et al.
This disruption in neurotransmitters is compounded by inflammation originating in the gut, further impacting mental well-being.
Reducing Inflammation and Oxidative Stress
Gut imbalances in PCOS can weaken the intestinal barrier, allowing harmful substances like lipopolysaccharides (LPS) to trigger inflammation and oxidative stress. This can damage the blood-brain barrier, worsening mental health. Women with PCOS often show higher levels of oxidative stress markers (like malondialdehyde) and reduced antioxidant levels (such as glutathione). When LPS activates immune cells, it leads to the release of inflammatory cytokines like tumor necrosis factor-alpha and interleukin-6. These not only interfere with insulin function but may also drive excess androgen production, worsening both PCOS symptoms and mental health challenges.
"Systemic inflammation and endotoxemia caused by LPS penetration, followed by pro-inflammatory cytokines and immune response, can destroy the tight junction proteins of endothelial cells within the blood–brain barrier (BBB) and promote the BBB permeability." – Negin Nikrad et al.
A 2023 study sheds light on this process: obese women with PCOS who took 5 grams of spinach thylakoid membranes daily for 12 weeks saw a drop in LPS levels (from 2.35 ± 0.20 EU/ml to 2.21 ± 0.23 EU/ml) and an increase in brain-derived neurotrophic factor (from 14.05 ± 1.25 ng/mL to 15.34 ± 1.73 ng/mL), suggesting better communication between the gut and brain.
Gut Bacteria Balance and Health
Beyond neurotransmitters, an unbalanced gut microbiome can disrupt hormone regulation and fuel inflammation. Women with PCOS face a 4- to 5-fold higher risk of mood disorders, often linked to unhealthy gut bacteria. Studies reveal that women with PCOS and mood disorders tend to have less diverse gut bacteria and lower levels of beneficial microbes like Butyricicoccus. At the same time, harmful bacteria like Sutterella are more prevalent, correlating with obesity markers, glucose issues, and weakened gut barriers. Certain bacteria that influence GABA levels in cerebrospinal fluid are also found in higher amounts in PCOS patients, further connecting gut imbalances to psychiatric symptoms. A reduction in bacteria producing short-chain fatty acids adds to inflammation and insulin resistance.
"Furthermore, the alterations in the gut bacteriome can influence anxiety and depression, collectively referred to here as MDs, by (i) regulating the synthesis of neurotransmitters and their precursors, such as serotonin, gamma-aminobutyric acid, and tryptophan, (ii) altering neuropeptide and gut hormone release, as well as brain-derived neurotrophic factor, and (iii) promoting neuroinflammation." – S Lee et al.
This imbalance also disrupts hormone levels. Altered gut flora can increase circulating androgens, which in turn lower serotonin and dopamine levels. These findings highlight the potential of targeted therapies like vitamin D and probiotics to restore gut health and improve both hormonal and mental health in women with PCOS.
Practical Treatment Options for PCOS
Recent research highlighting the connection between vitamin D, probiotics, and mental health in PCOS opens the door to practical treatment strategies that can improve daily care. By focusing on the relationship between gut health and mental well-being, tailored treatment plans incorporating these elements can make a noticeable difference. Below, we explore how personalized approaches and modern healthcare delivery methods are shaping PCOS management.
Personalized Treatment Plans for PCOS
Managing PCOS goes beyond simply adding supplements to your routine. Effective care requires a comprehensive plan developed by qualified professionals that addresses both physical symptoms and mental health challenges.
"Consulting with a gynecologist and dietitian is vital to managing hormones, regulating glucose levels, and testing for other metabolic disorders to improve one's symptoms through nutrition." – Dorothy Tran, Georgia State University
It all starts with lab tests. Since vitamin D deficiency is common in women with PCOS, assessing levels and monitoring hormonal health are critical. This ensures that supplementation is safe and tailored to individual needs.
Evidence supports the combined use of vitamin D and probiotics. Studies have shown improvements in depression, anxiety, and stress when these are used together.
"Overall, the co-administration of vitamin D and probiotic for 12 weeks to women with PCOS had beneficial effects on mental health parameters, serum total testosterone, hirsutism, hs-CRP, plasma TAC, GSH and MDA levels." – Ostadmohammadi et al., 2019
When it comes to vitamin D, doses up to 4,000 IU daily have been found effective and safe. A 2017 study involving 90 insulin-resistant women with PCOS revealed that taking this dose for 12 weeks led to reductions in testosterone levels and inflammation markers, all without side effects.
For probiotics, multi-strain formulations seem to deliver the best results. Research by Kaur et al. in 2022 used a blend of seven bacterial strains and fructo-oligosaccharides, leading to improved testosterone levels, body measurements, and overall quality of life - again with no adverse effects reported.
Convenient and Affordable Treatment Access
In addition to personalized care, modern healthcare delivery models are making PCOS treatment more accessible and consistent. Telehealth services, in particular, are proving essential for addressing both hormonal and mental health needs, especially for those who face barriers to in-person care.
The shortage of endocrinologists means that patients in urban areas often wait over four months for an appointment. Telehealth bridges this gap, offering convenience and timely care.
"Telehealth is closing an enormous gap for women with PCOS who live far from specialized care. It's proving to be not only convenient but clinically effective." – Dr. Jessica Sanders, reproductive endocrinologist at the University of Utah Health Center
Platforms like Oana Health are leading the way by offering personalized treatment plans for PCOS. Their licensed professionals can prescribe medications such as Metformin ($22/month), Spironolactone ($14/month), and Bupropion XL for mental health support ($25/month). These treatments are shipped directly to patients' homes with free delivery, making it easier to stay consistent with supplementation.
But telehealth isn’t just about medication. Many platforms also provide integrated mental health support, recognizing the strong link between hormonal imbalances and mental health issues like anxiety and depression. This comprehensive care model allows for regular monitoring and treatment adjustments without the need for in-person visits. It’s an approach that aligns with findings showing the mental health benefits of targeted supplementation.
"By using telehealth, we can make weekly tweaks to a patient's diet, medication, or lifestyle without them having to leave home." – Dr. Lisa Chang, telehealth coordinator at Emory Women's Health Center
Telehealth also helps reduce costs. According to a 2023 study published in Telemedicine and e-Health, telehealth services lowered out-of-pocket expenses for PCOS patients by 40%. This reduction comes from saving on transportation, minimizing time off work, and benefiting from transparent pricing.
Patient satisfaction with telehealth care for PCOS is high. Over 75% of users of specialized platforms report feeling better within a month of starting their personalized plans. Many express relief at finally finding providers who understand the complex relationship between PCOS symptoms and mental health.
The team-based approach offered by telehealth platforms is another major advantage. Patients gain access to a network of specialists, including gynecologists, dietitians, and mental health professionals, who collaborate to create a comprehensive care plan. This ensures that vitamin D and probiotics are just one part of a broader strategy addressing lifestyle, stress management, and ongoing health monitoring for the best possible outcomes.
Conclusion: Vitamin D and Probiotics for PCOS Mental Health
Studies reveal that taking vitamin D and probiotics together for 12 weeks can lead to noticeable improvements in depression, overall mental health, and stress levels in women with PCOS.
This combination works by enhancing vitamin D absorption and boosting the production of key neurotransmitters like dopamine, norepinephrine, GABA, and serotonin.
"The synergism between the immunomodulatory, antioxidant, and anti-inflammatory properties of both supplements might enhance their impact on mental health parameters." – Ostadmohammadi V, Jamilian M, Bahmani F, Asemi Z
In addition to mental health benefits, this approach lowers testosterone and inflammatory markers like hs-CRP while increasing antioxidant capacity. It also helps regulate the microbiota-gut-brain axis, which plays a significant role in overall well-being.
Considering that 57% of women with PCOS face mental health challenges - and are three to eight times more likely to experience anxiety and depression compared to others - addressing mental health as part of PCOS treatment is vital. The high prevalence of these issues highlights the importance of targeted interventions.
Tailored care based on this evidence is crucial. For instance, Oana Health offers telehealth-based PCOS care that combines mental health support with customized hormonal treatments, all delivered to your doorstep.
Incorporating vitamin D and probiotics into treatment plans provides a science-backed way to tackle both the mental and metabolic aspects of PCOS.
