Folate
600mcg of folate (the natural form of folic acid) as per current research for optimal folate status. Most prenatals provide less, despite its essential role in maternal tissue growth and healthy neural tube development.
Vitamin B6
Supports hormonal balance during pregnancy and breastfeeding, helping the body adapt to increased nutritional demands while supporting energy and nervous system function.
Magnesium
150mg of magnesium to support muscle relaxation, helping with cramps, stress resilience and restorative sleep. Most prenatals underdose this essential mineral despite its importance for nervous system balance and overall maternal wellbeing.
Choline
For foetal brain development, yet most prenatals provide little or no choline. Works synergistically with folate to support healthy neural development and cognitive function during critical stages of growth.
B Complex
A powerful complex that supports sustained energy production, stress resilience, balanced mood, and restorative rest during times of increased physical and emotional demand.
Vitamin D3+K2
An essential combination for bone health, yet K2 is often missing from prenatal formulations. Together they support optimal calcium absorption and utilisation, helping direct calcium where it is needed most for both mother and baby.
Selenium
Supports healthy thyroid function and antioxidant protection, helping meet increased thyroid demands during pregnancy and postpartum recovery. Often omitted, despite its important role in hormone balance, immune function and healthy foetal development.
Beta carotene
A gentle, safe source of provitamin A to support immune health, skin integrity and normal cell development, without the concerns associated with high intakes of preformed vitamin A.
Zinc
Often underdosed despite its essential role in foetal growth, normal cell division and DNA synthesis. The Booster provides 15mg to support healthy development, immune resilience and maternal recovery.
Calcium
Delivered as calcium citrate and calcium ascorbate — highly bioavailable forms often missing from standard prenatals. Essential for supporting maternal bone health while helping build your baby’s growing bones and teeth.
Vitamin C
Supports immune function, collagen formation and normal energy-yielding metabolism. It also helps enhance calcium absorption while supporting connective tissue health throughout pregnancy and postpartum recovery.
Vitamin E
A powerful antioxidant that helps protect cells from oxidative stress while supporting skin integrity and overall maternal wellbeing during times of increased physiological demand.
Copper
Supports normal immune function, connective tissue formation and antioxidant protection. It works alongside zinc to support healthy development and essential metabolic processes.
Chromium
Supports healthy blood sugar balance and normal macronutrient metabolism, helping the body efficiently process nutrients during pregnancy’s increased metabolic demands.
Molybdenum
A vital trace mineral that supports enzyme function and nutrient metabolism, helping the body efficiently process key compounds needed for maternal and foetal wellbeing.
Manganese
Supports connective tissue formation, antioxidant protection and normal energy metabolism, helping meet the increased nutritional demands of pregnancy.
Boron
A supportive trace mineral that works synergistically with calcium, magnesium and vitamin D to support healthy bone metabolism and overall mineral balance.

Still Have Questions?
What is The Booster and how is it different from a standard prenatal?
The Booster is a comprehensive powdered multivitamin designed by leading doctors and nutritionists for pregnancy and breastfeeding. It delivers bioavailable forms and therapeutic doses of essential vitamins and minerals for optimal maternal and fetal nutrition. Unlike most other prenatals, it is sugar-free, contains no synthetic ingredients or other nasties, and is in an easy-to-drink one-a-day sachet.
Why is The Booster a powder instead of tablets or capsules?
Powder offers several advantages during pregnancy:
- Gentler on digestion (no heavy tablets to break down)
- Better absorption potential
- Easier to take, especially during nausea or food aversions
- Allows for meaningful nutrient doses without swallowing multiple pills
It’s designed to be mixed into water for a light, palatable daily drink.
Does The Booster replace my prenatal supplement?
For most women, yes. Note that The Booster does not contain iron or iodine as these nutrients may or may not be suitable and require a more personalised approach.
Why doesn’t The Booster include omega-3?
While Omega-3 supports foetal development, we chose not to include it in this powdered formula. Omega-3s can oxidise and go rancid easily when exposed to air; therefore, we recommend taking them separately in a sealed, high-quality softgel capsule to protect their purity and potency.
Does The Booster contain vitamin A?
Yes, as beta-carotene, a safe precursor form.
Why are the nutrient doses higher than in some prenatals?
Many prenatal supplements are formulated around minimum recommended intakes (NRV). The Booster takes a different approach and provides doses informed by scientific literature and clinical practice and designed to support increased physiological demands during pregnancy and breastfeeding.
Why does The Booster contain 600mcg of folate?
The standard 400mcg dose found in many prenatals is the minimum requirement, whereas 600mcg aligns with increased requirements in pregnancy, including recommendations used in the U.S and is critical for supporting rapid foetal growth and meeting demands for placental development and methylation pathways.
Does The Booster support energy levels during pregnancy?
Yes. Pregnancy significantly increases energy demands at a cellular level. The Booster includes nutrients that contribute to energy-yielding metabolism (B vitamins) and the reduction of fatigue and tiredness (magnesium and vitamin C).
Can The Booster help with nausea or digestive discomfort?
While not designed as a treatment, many women find powder formats easier to swallow during episodes of morning sickness, easier to tolerate than tablets and less likely to cause digestive heaviness or nausea.
Is The Booster suitable for breastfeeding?
Yes, The Booster is designed to support both pregnancy and breastfeeding. During breastfeeding, nutrient demands remain high due to milk production and ongoing maternal recovery.
Can I take The Booster if I am trying to conceive?
Yes, The Booster can be used as part of preconception support and provides key nutrients such as Folate, Zinc, Selenium and B vitamins which play important roles in cell division, hormonal balance, and preparing the body for pregnancy.
Is The Booster suitable for vegetarians or vegans?
The Booster is suitable for vegetarians and vegans.
Are there any ingredients that have been deliberately excluded?
Yes, The Booster has been carefully formulated to include what matters and leave out what doesn’t. Deliberate exclusions include iron (to allow personalised supplementation), iodine (due to individual thyroid or autoimmune considerations), omega-3 (better supplemented separately) and botanical adaptogens (due to limited safety data in pregnancy).
How long should I take The Booster for?
Throughout pregnancy, breastfeeding, and optionally preconception. Consistency is key, as many nutrients work by Supporting ongoing physiological processes and building and maintaining nutrient stores over time.
Is The Booster safe to take alongside other supplements?
In many cases, yes, but this depends on what else you are taking. Common pairings include omega-3, iron (if prescribed), and probiotics. If you are on medication, we recommend checking with your doctor before starting The Booster.
What makes The Booster different from other “premium” prenatals?
The difference lies in the formulation philosophy:
- Form matters → bioavailable, active nutrients
- Dose matters → not just minimum levels
- Tolerability matters → gentle, powder-based delivery
- Individualisation matters → not everything forced into one formula
It’s designed to support real physiological demands, not just tick regulatory boxes.
What are the differences between The Elevator and The Booster
While both are comprehensive, doctor-formulated multivitamin powders, The Booster is specifically tailored for pregnancy and breastfeeding by prioritising proven maternal and fetal safety.
Choline, beta-carotene (a safe vitamin A alternative) and calcium were added, while folate was increased to support rapid fetal bone and brain development.
CoQ10, black pepper, and vitamin A were omitted due to limited safety data or toxicity risks during pregnancy.
