    All the benefits

    Trying to Conceive
    Vitamin D has been linked to higher ovulation and pregnancy rates in those with PCOS and may provide benefits to ovarian reserve markers like AMH. Plus, having solid Magnesium levels directly impacts how much energy is available to create good-quality eggs (and sperm!), while both Calcium and Magnesium are linked to increased sperm motility.
    Pregnancy
    Calcium, Magnesium, and Vitamin D are all essential to keep your baby’s skeleton growing strong. And—eek!—if you don’t have enough Calcium, the fetus will meet its needs by drawing from your bones, leaving you at risk down the road.
    Postpartum Recovery
    After pregnancy, labour and delivery, you’ll need more Calcium for energy production, muscle function, and cell protection. Vitamin D provides immune support, to help keep you healthy during challenging times.
    Overall Better Mental Health
    Lean on Magnesium to help to keep cortisol levels under control and get better sleep, and Vitamin D to help ward off feelings of depression as you’re trying to conceive, pregnancy and postpartum.

    All the good stuff in it

    Calcium, Magnesium, Vitamin D (x4)
    Inside each capsule, you’ll find a blend of Calcium, Magnesium and Vitamin D. They’re all served up in optimal forms for your body to absorb, so you can get max benefits to your reproductive (and overall!) health, from supporting positive pregnancy outcomes to newborn health. We’ve split the goods up into capsules so that they’re easier to swallow than a big chalky tablet. That way, we can pack in more goods to support you through every stage of the journey.

    What you may be asking yourself right now

    Is this product 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.

    I highly recommend Bird&Be prenatal supplements to all my patients who are trying to conceive. They provide a personalized and convenient approach, which makes their prenatals more efficient and enhances patient compliance.

    I'm thrilled for patients to be able to access higher and more effective doses of key ingredients than I've seen in other prenatals - three cheers for choline and CoQ10!

    Having an evidence-based approach to fertility-focused supplements is a key component to optimizing success, and it’s great that Bird&Be’s scientifically-backed prenatals are accessible to everyone, regardless of whether they’re seeing a fertility specialist.

    Bird&Be has hit all the right marks for prenatal and preconception care. They’ve removed the guesswork from patients' supplement regimes, while emphasizing dose education and including usable, active ingredient forms.

    Personalizing the formulas based on the individual's needs makes Bird&Be's supplements much more effective, especially for those who require a much more intensive regimen to support conception.

    It has been good. Packaging can be improved as the package is difficult to open

    Like it alright

    I miss the amount of magnesium in the previous supplement package. Only 50 mg now. I do like the addition of vitamin D though.

    Hi Shelaine,

    Thank you for your review!

    We now list ingredients based on doses per capsule versus per serving. The contents should be exactly the same but the ingredient reporting will be per capsule versus per sachet. It is still a total of 200 mg magnesium!

    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.
