Hormone Balance and Longevity Support for Women
Science-backed health solution for women, combining the eight essential nutrients for plant-based eaters, plus 6 vitamins and minerals to support longevity, vitality, and hormonal balance in women.
Even the healthiest diets have deficiencies. I'm always looking for simple, high-quality ways to fill in nutrition gaps. Complement's ForHer Essential System is one of my go-to sources. Think of it like wellness insurance."
Are traditional multivitamins failing women?
We turn to multivitamins for long-term health and extra security to cover our nutritional bases.
And for women, these needs extend beyond just basic nutrition — support for pre- and postnatal health, hormonal balance, menopause, and bone health are key concerns.
But the traditional multivitamin, even a woman-specific multivitamin, is failing to live up to its promise.
Here's why:
They’re stuffed with nutrients you already get from plant foods, leaving no room for recommended dosages of the vitamins and minerals you crave.
The result is added stress to your body, imbalanced hormones, irregular metabolism, a cloudy mind, and low energy.
So what can you do?
Until now, you've had two options:
- Take a half-baked women’s multi and hope for the best.
- Juggle a multi, prenatal, and single-nutrient supplements to get everything you need — wasting time and money in the process.
Now there's a better way.
With the ForHer Essential System, you can optimize your health and hormonal balance to feel like your healthiest, happiest self.
It starts with Complement Essential, containing the eight hard-to-get vitamins, minerals, and omega-3 fatty acids on a plant-based diet.
These eight nutrients were individually selected using the latest research (not trendy buzzwords) to support energy, immunity, and longevity.
And over the past six years, Essential has become the go-to solution for tens of thousands of plant-based and plant-forward customers who want to optimize their long-term health.
But as every woman deeply understands, you also have additional nutritional needs.
So for the past year, we’ve worked with Dr. Laurie Marbas, MD to identify the critical nutrients and dosages most impactful to female hormonal balance, cognitive function, and longevity.
In total, there are six additional nutrients, which combined with Complement Essential, create a complete science-backed solution to help you feel your best, most vibrant self every single day.

A Plant-Based Supplement, Rooted In Trust
The ForHer Essential System is formulated, produced, and third-party tested right here in the USA. Unlike most vitamin brands “white-labeling” products produced by another company, at Complement, we do it all ourselves. From sourcing to shipping, we’re with you every step of the way.
Ingredients highlights.
Vitamin K2
K2 isn't available in plant-based foods except for natto, a Japanese fermented soy product (and it's not in tempeh), so those eating Western diets need to supplement in order to get it.
Benefits:
Helps with heart and bone health.*
The smart part:
Vitamin K2 is the natural partner to Vitamin D3, acting as a regulator for increased calcium uptake and promoting good bone health. Complement Essential™ includes 50mcg of Vitamin K2 as menaquinone-7 (the natural and most absorbable form of K2) per daily serving, sourced from bacteria.
Vitamin D3
We love nature and spending time outdoors. But we also wear clothing, and most of us work inside during daylight hours. That means our natural ability to soak up the sun's rays is limited, and as a result, many of us — regardless of dietary pattern — might be deficient in Vitamin D
Benefits:
Supports bone health and immunity.*
The smart part:
While many vegan multivitamins contain the less effective D2 form, Complement Essential™ provides 2,000 IU of the only truly vegan D3 available (Vitashine, sourced from lichen) per daily serving.
DHA/EPA OMEGA-3S
Vegan food sources of Omega-3s like flax and chia seeds don’t provide two essential types — namely DHA and EPA. Seeds provide ALA Omega-3s, and are an amazing addition to your plate, but most people do not convert ALA into DHA and EPA.
Benefits:
Supports brain and cholesterol health, nervous system regulation, and improved energy levels.*
The smart part:
Complement Essential includes 300mg of DHA and 150mg of EPA per daily serving, sustainably sourced from algae grown under controlled conditions and tested for purity.
iodine
Worldwide, iodine deficiency affects two billion people and is the leading preventable cause of intellectual and developmental disabilities. In plant foods, iodine is found inconsistently and depends on the iodine content of the soil. It’s possible to get enough iodine if you regularly eat seaweed (multiple times a week), or use iodized salt, but this is one essential nutrient that shouldn’t be overlooked whether you’re vegan or not.
Benefits:
Supports healthy thyroid function, which regulates the metabolism.*
The smart part:
Complement Essential includes 150mcg of iodine per daily serving, sustainably sourced from kelp.
Magnesium
Soil depletion is a major cause of Magnesium deficiency in the overall population, and affects vegans as well as non-vegans.
Benefits:
Supports your metabolism, energy levels, mood, and heart health.*
The smart part:
Magnesium works to increase the efficiency of Iodine and helps regulate the thyroid function. Complement Essential includes 200mg of Magnesium per daily serving, in the form of magnesium citrate, the form that’s easiest absorbed by the body.
Selenium
Our depleted soil may mean that plant foods, in general, do not contain enough Selenium (and that’s even true for some Brazil nuts).
Benefits:
Supports brain health, mood changes, and heart health.*
The smart part:
Similar to Magnesium, Selenium works in tandem with Iodine to promote healthy thyroid function and metabolism, as well as the removal of heavy metals from the body. Complement Essential includes 50mcg of Selenium per daily serving, in the naturally occuring, plant-sourced form of L-selenomethionine.
Zinc
Legumes and seeds are the best natural sources on a plant-based diets, but vegans who avoid those food groups, as well as those who are worried about its bioavailability can benefit from the addition of Zinc with Complement Essential.
Benefits:
Supports the skin and nails, healthy growth and eyesight, wound healing, and a well-functioning immune system.*
The smart part:
Complement Essential includes 8mg of Zinc per daily serving, a zinc picolinate, the form easiest for the body to absorb and utilize.
Vitamin B12
Soil bacteria produce Vitamin B12 — which is essential for humans in order to protect neutral health and reduce inflammation. But modern agriculture and other human behaviors decimate these bacterial colonies that produce B12.
Benefits:
Supports red blood cell formation, neurological function, & DNA synthesis.*
The smart part:
Complement Essential contains 300mcg of B12 per daily serving, combining methylcobalamin and adenosylcobalamin, the easiest forms for the body to absorb and use.
IRON
Iron is an essential mineral needed for healthy red blood cells and oxygen transport, especially important for women of reproductive age due to their elevated needs.
Benefits for Women:
Prevention of anemia due to menstruation and support for energy levels: Helps in maintaining optimal energy levels, which can be especially beneficial during pregnancy and postpartum periods.*
The smart part:
Iron works synergistically with folate in red blood cell production, enhancing the overall oxygen-carrying capacity of the blood. The Iron Bisglycinate Chelate form is gentle on the stomach and has higher bioavailability compared to other forms, reducing the risk of gastrointestinal discomfort.*
FOLATE
Folate is a vital B-vitamin necessary for DNA synthesis and cell function, commonly found in diets abundant with leafy greens or fortified foods.
Benefits for women:
Critical during pregnancy for the proper development of the fetal nervous system. Supports mental health and plays a role in reducing the risk of depression and cognitive decline.*
The smart part:
Works synergistically with iron in red blood cell production, enhancing the overall oxygen-carrying capacity of the blood and choline to support healthy brain function and development. The Liposomal (6S)-5-Methyltetrahydrofolic Acid form is more readily absorbed by the body, ensuring better utilization compared to synthetic folic acid.*
BORON
Boron is a trace mineral that supports bone health and metabolism, typically found in fruits, vegetables, and nuts, but not always consumed in adequate amounts.
Benefits for women:
Helps in the metabolism of minerals that are essential for bone health, which is particularly important post-menopause and aids in maintaining optimal levels of estrogen.*
The smart part:
Works with magnesium and D3 to support the absorption and metabolism of calcium and promote bone density and skeletal health. The natural Calcium Fructoborate form of boron is well-absorbed and utilized by the body.*
CHOLINE
Choline is a crucial nutrient for brain and liver health, predominantly found in animal products, making it harder to obtain from a vegan diet.
Benefits for women:
Aids in preventing fatty liver disease, which can be more prevalent in women and supports brain health and cognitive function, crucial during pregnancy for fetal brain development.*
The smart part:
Works with Omega-3 Fatty Acids in supporting brain health and with B vitamins to enhance the metabolism of fats and cholesterol.
The Phosphatidylcholine form is easily absorbed and utilized by the body and does not raise TMAO levels like some other forms of choline.*
Copper
Copper is an essential trace mineral important for various bodily functions, often less abundant in diets low in organ meats and shellfish.
Benefits for women:
Essential for maintaining a healthy immune system and the proper utilization of iron.*
The smart part:
Enhances iron absorption and utilization and works synergistically with zinc to support a healthy immune response and skin health. The chelated Copper form is highly bioavailable and reduces the risk of gastrointestinal issues compared to inorganic forms.*
VITAMIN B9
A B-vitamin compound supporting cellular health and signaling, commonly found in fruits, beans, grains, and nuts, but often under-consumed.
Benefits for women:
Supports ovarian function and the proper functioning of the liver and gallbladder, which are both under more stress in women due to monthly hormonal fluctuations.*
The smart part:
Works with folate to support healthy cell growth and function and may support magnesium in enhancing insulin sensitivity and reducing symptoms of metabolic syndrome.
The Inositol form is particularly beneficial for reproductive and mental health, offering better absorption and utilization.*
K2 isn't available in plant-based foods except for natto, a Japanese fermented soy product (and it's not in tempeh), so those eating Western diets need to supplement in order to get it.
Benefits:
Helps with heart and bone health.*
The smart part:
Vitamin K2 is the natural partner to Vitamin D3, acting as a regulator for increased calcium uptake and promoting good bone health. Complement Essential™ includes 50mcg of Vitamin K2 as menaquinone-7 (the natural and most absorbable form of K2) per daily serving, sourced from bacteria.

Frequently asked questions.
Still not sure? Find answers to your questions here...
What are the nutrition facts?
I already take Essential, should I add ForHer?
Complement Essential was formulated to provide the missing or hard-to-get nutrients in a plant-based diet.
ForHer is a collection of essential nutrients not included in Essential. While these nutrients may not be missing from a plant-based diet, many plant-forward women may benefit from adding the additional dosages.
ForHer is designed to support hormonal balance, cognitive function, and longevity in women, and intended to be taken in addition to Complement Essential or another multivitamin.*
Are ForHer and Essential vegan?
Yes, all Complement nutrients are 100% vegan and cruelty-free. (And so are we.) All of the ingredients are sourced from plants, bacteria, minerals or algae.
Do Complement Essential or ForHer contain soy, nuts, gluten, GMO's or artificial ingredients?
Complement Essential and ForHer DO NOT CONTAIN: Soy, nuts, yeast, gluten, MSG, genetically modified organisms, artificial colors or flavors, fish, dairy, eggs or other animal-sourced ingredients.
Who is behind Complement?
We’re an all-vegan team on a mission to support the health of the vegan movement, by protecting the health of individual vegans with the nutrients they need to thrive. Through sourcing the highest quality ingredients and fully transparent production, we leave absolutely nothing on the table when it comes to developing essential, premium plant-based nutrition products.
Why did you make the Complement Essential capsules black?
The unprocessed and unrefined oil used in Complement Essential naturally contains other beneficial compounds including carotenoids, Omega-7, and Chlorophyll — which gives it a dark green color that appears nearly black.
What is the suggested use?
For adults and children over 12, take 3 Complement Essential and 2 ForHer vegan capsules daily, preferably with a meal. Store in a cool, dark place.
Can my children take the Complement Essential ForHer System?
We formulated Complement Essential for adults and kids over 12. If you wish to give it to younger children, please consult with your doctor or pediatrician and show them the full ingredients list to determine its suitability and dose.
Can I take Complement Essential together with my other supplements or multivitamin?
Complement Essential, together with a whole-food, plant-based diet, will provide you with the nutrients you need to thrive. Formulated for optimal nutrient intake, Complement Essential is safe and non-toxic when taken as directed. If you take another supplement that contains any of the nutrients found in Complement Essential, you may exceed the tolerable upper intake for that nutrient. Speak with your doctor if you have any questions about how Complement Essential works with any other supplements or medications you are taking.
