    Product Details

    An iconic trio, loved by researchers for every stage of the journey

    The perfect complement to your supplement routine: three nutrients that work together in one daily add-on. These 3 nutrients work as a team, which is why our doctors combine them in our Calcium + Magnesium + Vitamin D Boost. Magnesium activates Vitamin D, Vitamin D helps the body absorb Calcium, and Magnesium supports healthy Calcium balance.

    Each daily pack has four capsules containing:

    • Vitamin D3 (25 mcg/1000 IU): Vegan D3 helps your body absorb calcium and supports immune and hormone function.

    • Calcium (350 mg): Calcium Citrate, a gentle and highly absorbable form that keeps bones, teeth, and muscles strong.

    • Magnesium (200 mg): An easy-on-the stomach form to help combat iron-deficiency anemia and to support maternal red blood cell production.
    Who Is This For?

    This product is beneficial for people (both males and females) who are trying to conceive, are pregnant, postpartum or want a extra wellness boost. Truly a superpower combo!
    Key Benefits

    Supports Pregnancy Outcomes: Vitamin D is linked with higher pregnancy rates, lower miscarriage rates, and fewer pregnancy complications.*

    Helps to Improve Sperm Motility: Males can benefit too: both Vitamin D and Calcium help sperm swim better, which is key if they’re going to reach an egg for fertilization.*

    Supports Healthy Fetal Development: Calcium, Magnesium, and Vitamin D are all essential in pregnancy to keep your baby’s skeleton growing strong.*

    Supports a Smoother Postpartum Recovery: Pregnancy and body-feeding can deplete Calcium stores, leaving you vulnerable to bone loss, while low Vitamin D levels are linked to postpartum depression. Getting enough of both is key—along with Magnesium for better sleep, mood and hormone balance. (Plus, all three work their best when taken together.)*

    "I feel an increase energy and overall positive sense of self. It has given me the boost I need emotionally as well as physically."

    What's Happening
    Inside Over Time

    1. 30 Days

      Filling the Gaps

      Most people fall short on calcium, magnesium, and vitamin D from diet alone. Daily support starts topping up all three, so your body has steadier access to the minerals it draws on constantly.

    2. 60 Days

      Easing Everyday Tension

      As your magnesium levels build, its effects show up in the day to day. Magnesium supports muscle relaxation and calmer, more restful sleep, and helps take the edge off everyday stress.

    3. 90 Days

      Building Steadier Stores

      Vitamin D takes time to reach a healthy level in your body, and calcium works alongside it. Three months of consistent support helps build the reserves that back your bones, immunity, and hormone balance.

    4. Continued Use

      Building Steadier Stores

      Your body has no way to store some of these minerals long-term, so daily intake is what keeps levels steady. Ongoing support protects your bone strength and overall balance for the long haul.

    Frequently Asked Questions

    Is the Calcium + Magnesium + Vitamin D Boost right for me?

    This trio is a safe and effective product for all healthy adults, and is especially beneficial for those who are trying to conceive, pregnant, or postpartum. Since most of us are Vitamin-D deficient, supplementing helps to ensure we’re meeting the minimums we need, especially since it’s hard to get from the sun and our diets. Calcium and Magnesium are key minerals that support all stages of reproductive health, with many benefits outside of fertility, too. The bonus? Calcium, Magnesium, and Vitamin D complement each other when taken together, giving your overall health a welcome and super-effective boost.
    When can I start taking these supplements and for how long?

    You can take the Calcium + Magnesium + Vitamin D Boost throughout your fertility journey, from preconception through to postpartum and even beyond, getting enough of this trio is important for your overall health, too.
    I’m not pregnant, postpartum, or trying to conceive. Can I still take these supplements?

    Yes! Vitamin D, Calcium and Magnesium are all nutrients the body needs to function properly, even if your fertility isn’t top of mind. Unfortunately, many of us don’t get the recommended daily values we need from diet or sunlight alone and supplementation is a great way to ensure your stores don’t get low.
    When should I take the Calcium + Magnesium + Vitamin D Boost?

    We recommend taking the Calcium + Magnesium + Vitamin D Boost in the evening (and at least three hours away from Iron-containing supplements and thyroid medications to avoid absorption issues). Magnesium helps ease anxiety and muscle tension, making it ideal for your bedtime routine.
    Can I take the Calcium + Magnesium + Vitamin D Boost with my other pills?

    Give yourself three hours between taking the Calcium + Magnesium + Vitamin D Boost and other Iron-containing supplements, including any of Bird&Be’s preconception, prenatal or postpartum supplements. This is because the Calcium in the boost can interfere with Iron absorption. It’s best to space out Calcium from thyroid medication too (and you can always check with your doctor or pharmacist for any other meds you may be wondering about). We like to take this in the evening, as the Magnesium can help with sleep.
    Is the Calcium + Magnesium + Vitamin D Boost vegan?

    Yes! From the ingredients inside to the capsule itself, all parts of the Calcium + Magnesium + Vitamin D Boost are vegan.
    What’s the difference between the new Calcium + Magnesium + Vitamin D Boost and the old Calcium + Magnesium Boost?

    You guessed it from the name, we added Vitamin D! The Calcium + Magnesium + Vitamin D Boost has the same amount of Calcium and Magnesium as the previous formula, plus it now has 1,000 IU of vegan Vitamin D3. There’s mounting research (and excitement!) around the benefits of Vitamin D for fertility, so we wanted to make it easy for you to get an extra dose. We added it to this boost because, while Calcium is best taken apart from other nutrients like Iron, it pairs perfectly with both Vitamin D and Magnesium, in fact, all 3 work their best when taken together.You might also notice it’s now 4 capsules. We divvied up the goods so that they’d be easier to swallow. Calcium is notoriously a toughie, especially when it’s in a big chalky tablet. Our small capsules solve that, because what good are the very best nutrients if they’re too hard to take? As always, we’re here to give you research-backed ingredients in easy, convenient forms.
    What does Vitamin D do and why do I need so much?

    Vitamin D is essential for immune support and bone and cardiac health, and that’s even before we get to the fertility and pregnancy benefits. Unfortunately, about half of North Americans are deficient in the vitamin, and it’s hard to get what you need from sun or food alone. That’s where supplementing comes in. The Calcium + Magnesium + Vitamin D Boost has 1,000 IU of Vitamin D, covering the official doc-recommended daily value. And because many doctors and studies recommend daily doses up to 2,500 IU to benefit reproductive health and correct the deficiency many of us have, we recommend taking this product plus any of our preconception, prenatal, or postpartum supplements, which also contain 1,000 IU. That way, you can get a total of 2,000 IU daily, which is an effective dose yet safely within both the U.S. National Institute of Health’s and Health Canada’s tolerable upper intake level of 4,000 IU.
    Can I take this product if I'm taking other medication?

    If you have any concerns about medication, consider consulting your healthcare practitioner before use. We suggest spacing out your supplements from medication by at least three hours.

    Great product

    I liked this product a lot….very gentle on the stomach, can be taken in the evening without any stomach upset.
    My only negative comment is that I wish the vitamin D content was more. I initially purchased it because I needed additional vitamin D, but for me it wasn’t enough to get me where I needed to be. Depending on your needs though, this might be just what you need!

    Great product; silly packaging

    The vitamins themselves are good! They are a little hard to swallow, due to the amount of air in each, but it’s manageable. I absolutely hate the packaging though with all the tiny little unsustainable plastic pouches. Just put them all in one container. I can count out 4 a day.

    Thanks so much for your feedback! We totally get where you’re coming from. We use daily sachets because they make it super convenient to grab your full dose of essential vitamins, no need to juggle multiple bottles. Plus, the sachets are recyclable, so they’re a more sustainable option than they may seem at first glance! ☺️

    Packets missing capsules

    Interesting that my first review was deleted but here goes again. A few packets only contain 3 capsules instead of 4. Recycling symbol on single serve packs seems sketchy since without a number on the symbol I don’t know how to recycle it. My doc says I need more vitamin b6 and magnesium than this offers so probably won’t buy again.

    Hi there!

    Thank you for sharing your feedback! We're sorry to hear about your experience with the sachets containing fewer capsules than expected. This isn't the norm, and we'll be reaching out to address this directly.

    We noticed you mentioned a prior review, but we didn’t receive any other submissions from you. Your feedback is important to us, and we want to ensure your concerns are addressed!

    Regarding recycling, our sachets are marked as number 7, and our updated packaging will include the number clearly to avoid any confusion.

    As for B6, we include this in other supplements rather than in our Calcium + Magnesium + Vitamin D Boost. Calcium + Magnesium + Vitamin D Boost is designed as a comprehensive boost to support fertility, fetal development, postpartum recovery, and more for both females and males.

    We truly value your input and hope to better meet your needs in the future! If there's anything else we can help with, please don’t hesitate to let us know.

    Very convenient!

    I like the convenience of the pre-portioned doses but am concerned about the amount of waste that comes with it. My hope is that the pouches are compostable?

    LOVE this!

    Beyond impressed with the Magnesium/Calcium/Vitamin D supplement. It WORKS. I am always very constipated and after one night of taking half a dose of this, I was able to have a normal bowel movement. Make sure you work your way up to the full dose! You can definitely get a stomach ache from all the magnesium if your body isn’t used to it yet. My only wondering is that I’ve seen you’re not supposed to take magnesium and calcium together since they affect each others absorption, so I was curious why these are combined. However, I was looking for these exact vitamins so it makes it much easier that theyre combined. They are also 100% tasteless and do not have an odor.

    My bedtime routine

    This is the most convenient way to get these great ingredients in my routine. Especially for calcium—I've long struggled to take calcium supplements because they tend to be so hard to swallow, but these ones are nice and easy. I take my Prenatal Essentials in the morning and these at night, and feel confident I'm getting everything I need to support my pregnancy.
