Supported by expert guidance, integrative wisdom, and compassionate care
Certified Nurse Midwife · Women's Health Nurse Practitioner
Welcome
Access personalized guidance grounded in over two decades of clinical experience, integrative medicine, and mindfulness-based practice.
The Support
Pregnancy can suddenly come with an entirely new language: screening tests, ultrasounds, lab results, supplements, symptoms, and decisions you may never have imagined having to make.
Together, we make sense of the information so you can better understand your care, explore your options, and make decisions that reflect your health, circumstances, and values.
There is an enormous difference between simply receiving information and feeling informed.
Birth asks us to prepare in more than one way. Together, we explore the physical, emotional, and practical aspects of labor so you can approach birth with greater confidence and trust.
The goal is not a perfect birth. It is to enter the experience feeling informed, supported, and grounded in trust.
The weeks after birth are about so much more than caring for a newborn. Your body is recovering, relationships are shifting, and you are finding your way into a new version of yourself.
With the right support, postpartum can be a time to recover, connect, and find your footing in this new chapter.
How We Work Together
One focused 60-minute session centered entirely around you. Bring the questions, decisions, or experiences that have been taking up space. Leave with clarity and a personalized follow-up.
Three private sessions to help you approach birth informed, grounded, and prepared. Covers what to expect, coping tools, mindfulness, partner preparation, and your birth preferences.
Five private sessions of personalized support through pregnancy, birth preparation, and early postpartum. SaYa's most comprehensive offering for those who want a trusted guide alongside them.
"I can't tell you enough how your training supported us. We managed to give birth without pain control thanks to your precious advice"

About Sasha
I started SaYa Rebirth to create a critical added layer to your pregnancy care: one that blends clinical expertise with integrative medicine, mindfulness-based practice, and whole-person support.
From 1:1 coaching to group Mindful Birthing programs, there are several ways to work together, wherever you are in your journey.
About Sasha
Over two decades of experience in preconception, pregnancy, birth, and postpartum care.
I'm Sasha Yamnik, a Certified Nurse Midwife, Women's Health Nurse Practitioner, and Clinical Professor at UCSF, where I trained as a midwife and now help shape the next generation of midwives and OB-GYN physicians.
For more than two decades, I have cared for women and families, and I have had the privilege of being present for thousands of deeply personal moments: from the quiet anticipation of a positive pregnancy test to the raw intensity of birth and the enormous, identity-reshaping transition into parenthood.
I have caught enough babies at 3 a.m. to know that catching the baby is sometimes the easy part.
What I have witnessed, over and over, is this: people need more than excellent medical care. They need to feel heard. They need space for their story, their fears, and all the parts of their lives that quietly shape their health. And they deserve care that honors that complexity, not just the condition or symptom that brought them through the door.
In today's healthcare system, time can be limited and care can feel fragmented. There is rarely enough space to sit with the questions beneath the questions: What am I afraid of? What does my body actually need? What choices feel right for me, in my life, with my values? How do my mental health, relationships, nutrition, and past experiences shape the way I move through this transition? How do I heal from something that hurt me?
It was these questions, and a desire to care for the whole person more deeply, that led me to pursue additional training in mindfulness-based childbirth and parenting, integrative psychiatry, trauma-informed care, and integrative and functional medicine.
I believe some of the most meaningful care begins with deep listening.
SaYa Rebirth grew from that conviction.
SaYa offers an additional layer of individualized support that works alongside your medical care. We begin with your story, your concerns, and what matters most to you. From there, I bring together evidence-based obstetric knowledge, integrative medicine, and psychoemotional support to help you make informed choices that feel grounded in who you are, and who you are becoming.
I would be honored to be a part of your story.

Book This Series03
Five private sessions of personalized support through pregnancy, birth preparation, and early postpartum.
*Includes availability by call or text during the birth to help guide challenging decisions.
Pregnancy is not one moment or one decision. It is a journey filled with questions, choices, physical changes, emotional shifts, and an extraordinary amount of information to navigate.
The Full Journey is SaYa's most comprehensive offering, created for those who want a trusted guide alongside them throughout the transition.
Across six 60-minute private sessions, our work evolves with you and your pregnancy. We begin with you: your health, your story, your questions, your values, and the kind of support you are seeking. From there, we create space for the things that may not fit into a routine prenatal visit.
Make sense of prenatal recommendations, testing, lab results, nutrition, supplements, movement, common pregnancy concerns, and the questions you want to bring back to your medical team.
Create space for the fears, expectations, relationships, previous experiences, and emotional changes that can surface during pregnancy. We can incorporate mindfulness and other integrative tools to help you feel more grounded as you move through this transition.
Prepare for labor with evidence-based education, mindfulness practices, coping tools, partner preparation, and thoughtful exploration of your birth preferences. We will also prepare for the possibility that birth may take a different path than expected. During your birthing process, I will be available by phone to offer support when challenging or unexpected decisions arise.
Prepare for recovery and the realities of life after birth, including emotional well-being, sleep, nutrition, relationships, household dynamics, newborn care, and the support you may need at home.
After your baby arrives, there is space to come back together and debrief your birth. Whether your experience felt beautiful, difficult, unexpected, empowering, or a mixture of many things, you deserve time to tell the story and begin making sense of what happened.
You don't have to anticipate every question or prepare for every possibility. The Full Journey gives you a trusted place to bring what comes up, as it comes up.
Investment $1499
My hope is that you move through pregnancy feeling informed and supported, enter birth grounded in trust, and begin postpartum feeling fully supported.
Begin the JourneyIf you are seeking a course on childbirth and parenting that also helps you to develop invaluable skills to ride through the contractions of life, you have come to the right place.
Having a baby is often one of the most transformative experiences in a person's life. No matter how they go, pregnancy and birth are intense both physically and emotionally, preparing us for the journey of parenting.
The practice of mindfulness has been shown in medical literature, time and time again, to have the benefit of easing many of life's challenging transitions. Mindfulness is defined as the awareness that comes from learning to pay attention, in the present moment, on purpose and non-judgmentally.
Through this invaluable practice we learn to navigate not only the birthing process, but also our day-to-day, moment-to-moment, life as parents and as humans.
People who practice mindfulness find they have a decrease in stress level, higher coping capabilities, and less emotional reactivity. Mindfulness guides the ride on waves of life with less tension, less fear and more peace.
Evidence-Based
Mindfulness-Based Childbirth and Parenting (MBCP) is one of many Mindfulness-Based Interventions, and was founded by midwife and mindfulness teacher Nancy Bardacke in 1998. MBCP is an evidence-based adaptation of the well-researched Mindfulness-Based Stress Reduction program (MBSR) created by Jon Kabat-Zinn, Ph.D. in 1979 at the University of Massachusetts Medical Center.
Mindfulness-based programs are currently found in hospitals, clinics, and schools all over the world. Many examples of the therapeutic impact of Mindfulness-Based Interventions (MBIs) are found in peer-reviewed medical, mental health and educational journals. You can explore the current research here.
Program Enrollment
The next Mindful Birthing Bay Area cohort is in preparation. This evidence-based MBCP program will be hosted on Kajabi, offering a rich online learning environment alongside in-person sessions.

Nourish
Evidence-based information to empower your choices throughout pregnancy and beyond.
Nutrition plays a central role in both fertility and pregnancy. Not all prenatal vitamins are created equal, quality, nutrient form, and dosing all matter. Here is an evidence-based guide to the nutrients that matter most and a trusted source.
Essential Nutrients in Your Prenatal
Supports the baby's nervous system and chromosomal development. Adequate intake supports egg quality, reduces miscarriage risk, and helps prevent neural tube defects. Methylfolate is the bioactive form usable by everyone, including those with MTHFR variations.
400–800 mcg dailySupports healthy progesterone levels and a supportive uterine lining for implantation. Many women, especially those who have used hormonal contraception, begin pregnancy with lower B6 levels. May also help reduce nausea.
5–10 mg daily (pyridoxal-5-phosphate)Supports fetal brain development and healthy oxygen transport. Iron deficiency is associated with impaired immunity, increased infection risk, fetal growth restriction, and preterm birth. Look for iron chelate for gentler digestion.
~27 mg daily (iron chelate)Essential for healthy thyroid function, which influences fertility, menstrual health, and metabolism. During pregnancy, iodine supports the baby's brain and nervous system development. Even mild deficiency has been linked to reduced cognitive outcomes.
200–250 mcg dailyEssential for fetal brain development, particularly for memory, learning, and cognitive function. Many prenatal vitamins contain little or no choline. Emerging research suggests higher intake may further support fetal brain development.
At least 450 mg dailyPlays a role in ovulation, hormone balance, immune health, and protection of developing eggs from oxidative stress. Also important for fetal brain development throughout pregnancy.
15–45 mg dailyAdditional Supplements to Consider
DHA and EPA support egg development, embryo formation, and fertility. DHA is especially important for the baby's brain and nervous system, and may reduce preterm birth risk. EPA supports mood regulation and may help reduce prenatal and postpartum depression.
Combined DHA/EPA supplementInfluences hormone regulation, fertility, and immune function. Adequate levels may improve pregnancy outcomes and are associated with higher conception rates. Prenatal vitamins typically contain insufficient amounts.
~2,000 IU daily (test to individualize)Vaginal and gut microbiome balance can influence fertility and pregnancy health. Lactobacillus species may support healthy microbial balance, immune regulation, and reduce inflammation. May also reduce eczema, allergies, and asthma risk in children.
Lactobacillus-containing probioticWhen to start: At minimum, ensure you are receiving at least 800 mcg of methylfolate and about 2,000 IU of vitamin D daily. Ideally begin a prenatal vitamin three to six months before trying to conceive. Continue for at least three months postpartum, and through breastfeeding.
Quality matters: Look for products tested by NSF International, USP, or the Clean Label Project. Many products on the market do not fully meet the nutritional needs of pregnancy. When evaluating, consider both the amount and the form of each nutrient.
Where to purchase: You can purchase supplements on any reputable site, look for products verified by NSF International, USP, or the Clean Label Project. We recommend avoiding Amazon due to inconsistent storage and product regulation standards, which can compromise quality and efficacy.
A trusted source: The supplement store at us.fullscript.com/welcome/keribrookshealth is hosted by Kari Brooks, a functional nutrition practitioner and college educator. Sasha selected the products and reviewed the suggested dosages based on her integrative training and the current evidence. The suggested supplements can be found under featured product collections.

Well-Being
Through pregnancy, postpartum & transition.
Pregnancy and postpartum are among the most significant transitions a person can move through. They bring joy and meaning, and they also bring disruption, to identity, relationships, sleep, the body, and sense of self. These changes are real, and they deserve to be taken seriously.
Perinatal mood and anxiety disorders (PMADs), including depression, anxiety, OCD, PTSD, and postpartum psychosis, are the most common complication of pregnancy and postpartum, affecting up to one in five people. They are not a sign of weakness or failure. They are medical conditions that respond well to treatment.
Emotional health is not separate from the health of your pregnancy. It is part of it. Untreated depression and anxiety during pregnancy have been associated with preterm birth, difficulty with attachment, impaired self-care, and, in severe cases, significant harm to both parent and baby. Taking care of your emotional health is part of taking care of your pregnancy, your baby, and you.
At SaYa Rebirth, emotional wellness is central to care, not an afterthought. Whatever you are carrying, you do not have to navigate it alone.
This is one of the questions I hear most often, and I understand why. Pregnancy can make every decision about what goes into your body feel bigger. When it comes to mental health, the question is not simply, "Is this medication safe?" It is also, "What are the risks of my symptoms going untreated?"
We still have more to learn about all medications in pregnancy. But we have decades of research on commonly used antidepressants, particularly SSRIs. The American College of Obstetricians and Gynecologists (ACOG) states that robust evidence supports the use of SSRIs when clinically indicated and that most SSRIs have not been associated with an increased risk of birth defects. Just as importantly, untreated depression and anxiety are not without risk, they have been associated with poorer engagement in prenatal care, preterm birth, preeclampsia, low birth weight, difficulty with attachment, substance use, and, in severe cases, suicide.
For some people, medication is not something to fear or feel guilty about. It can be an important, and sometimes lifesaving, part of caring for both parent and baby.
That said, like any medication, SSRIs carry potential risks, including a moderately increased likelihood of preterm birth and low birth weight, and a slightly increased risk of preeclampsia and postpartum hemorrhage. This is exactly why individualized, skilled guidance matters: not to create fear, but to help you make an informed decision that accounts for both the risks of treatment and the risks of leaving symptoms untreated.
ACOG: Statement on the Benefit of Access to SSRIs During Pregnancy →There is no single "best" antidepressant or dose for every pregnant person. Your history matters: what has worked before, the severity of your symptoms, whether you are already stable on medication, your other health conditions, and where you are in pregnancy.
SSRIs are commonly used for depression and anxiety during pregnancy. Pregnancy alone is generally not a reason to abruptly stop or change a psychiatric medication that is keeping you well. This is where individualized care matters. ACOG recommends that mental health medications not be withheld or discontinued solely because someone is pregnant or breastfeeding, and that symptoms be monitored with validated tools with the goal of achieving remission.
ACOG: Treatment and Management of Mental Health Conditions During Pregnancy and Postpartum →If you discover you are pregnant while taking an antidepressant, please don't stop it suddenly out of fear. Bring your medication list to your midwife, OB, primary care clinician, or psychiatrist and have a thoughtful conversation about the benefits and potential risks of your specific medication.
For many people who are doing well on treatment, continuing an effective medication may carry less risk than stopping and experiencing a recurrence. If a change is appropriate, it should be individualized and made together with the clinician managing your medication. The goal is not to take the smallest possible amount of medication at any cost. The goal is to keep you well while thoughtfully minimizing unnecessary exposure.
This is where I believe conventional and integrative medicine can work beautifully together. Medication does not have to replace everything else that supports emotional health. Depending on your individual needs, an integrative plan may also include:
Targeted nutritional and supplement support may also be part of an integrative plan. Visit the Nourish page for evidence-based supplement guidance, or scroll up to the mood-specific supplement section on this page.
After years of caring for families through pregnancy, birth, and postpartum at UCSF, and working alongside psychiatrists and other specialists, I have learned that emotional wellness rarely comes from a single intervention. My approach brings together perinatal health with training in integrative psychiatry, integrative medicine, mindfulness, nutrition, and whole-person care.
Sometimes the right support is therapy. Sometimes it is medication. Sometimes it is strengthening sleep, nutrition, movement, connection, mindfulness, or correcting an underlying deficiency. And often, it is a thoughtful combination. This is not about choosing between conventional medicine and a more natural approach. It is about finding the combination that helps you feel like yourself again.
- Sasha Yamnik, CNM
"Natural" does not automatically mean safe in pregnancy. Supplements and herbal therapies can have physiologic effects, interact with medications, and often have less pregnancy-specific safety data than commonly prescribed medications. They deserve the same thoughtful, individualized approach.
Pregnancy and postpartum bring enormous emotional change, but you do not have to wait until you are in crisis to ask for support. Consider reaching out to your midwife, OB, primary care provider, therapist, or psychiatrist when sadness, anxiety, worry, or overwhelm begins to feel persistent or interferes with your ability to sleep, eat, concentrate, function, connect with others, or experience joy.
ACOG recommends screening for depression and anxiety at the initial prenatal visit, later in pregnancy, and postpartum using validated tools. ACOG Perinatal Mental Health Screening · Patient Screening Resources
You can also check in with yourself using two validated screening tools. These are starting points for conversation, not diagnoses. How you are feeling and functioning matters just as much as any number.
Your score is a starting point for conversation, not a measure of how much support you deserve.

Work With SashaPerinatal anxiety is common and often undertreated. The following supplements have evidence supporting their use for anxiety during pregnancy and postpartum. Always discuss with your provider before starting any new supplement.
Anxiety Support
Increases GABAergic availability, supporting the nervous system's ability to calm. The form matters: glycinate has the best data for anxiety and sleep; citrate is a good option if constipation is also a concern.
200–400 mg daily (up to 800 mg)A naturally occurring amino acid found in tea. Works by activating alpha brain waves, a state of wakeful relaxation, without causing drowsiness. Also studied for sleep, immunity, and cognition (including ADHD). May decrease blood pressure slightly.
200 mg three times dailyA member of the mint family with calming properties. Improves anxiety and supports digestion. Can be taken as a tea or in capsule form.
300 mg via tea or capsuleAn adaptogen that reduces cortisol levels and decreases the body's physiological response to stress. Also has antioxidant and anti-inflammatory properties. Note: use with guidance from your provider during pregnancy.
200–600 mg dailyA pseudovitamin (sometimes called Vitamin B8) that supports blood sugar regulation and has evidence for anxiety and panic disorders. Start low and titrate slowly, high doses can cause loose stools.
4–18 g daily (start at 1 g, increase by 1 g per week)Perinatal depression affects up to 1 in 5 people and can begin during pregnancy, not only postpartum. These supplements support neurotransmitter synthesis and anti-inflammatory pathways associated with mood.
Depression Support
Anti-inflammatory fatty acids that influence serotonin and dopamine production. Target 1–2 g EPA (or EPA:DHA ratio of 2:1). High-dose use for 8 weeks has the strongest evidence for acute treatment; can also be used for prevention or maintenance. Consider Nordic Naturals Ultimate Omega or adding salmon roe to the diet (≈3.5 g EPA/DHA per 100 g).
Start 300–600 mg, increase over 2 weeks to 1–2 g EPAAn amino acid that supports synthesis of neurotransmitters and assists in anti-inflammatory and neuroprotective processes. Has been shown to improve cognitive function in depressed patients.
200–1,200 mg dailyA B vitamin essential for the synthesis of serotonin and dopamine. Pregnancy and genetic factors such as the MTHFR mutation can inhibit folate conversion. L-methylfolate is the active form used directly by the brain, standard folic acid requires multiple conversion steps before it can be used for neurotransmitter synthesis.
15 mg daily (standard pregnancy dose is 400 mcg; therapeutic mood dose is significantly higher)When to start: At minimum, ensure you are receiving at least 800 mcg of methylfolate and about 2,000 IU of vitamin D daily. Ideally begin a prenatal vitamin three to six months before trying to conceive. Continue for at least three months postpartum, and through breastfeeding.
