Prenatal Vitamin Ingredients | What's Inside Storkling

Why this exists

A prenatal only works if it is taken consistently.

We started Storkling after hearing the same thing over and over from women we care about.

“I know prenatals are important. I just struggle to take pills every day.”

It was not a lack of awareness. Most women already knew which nutrients mattered during pregnancy. The challenge was consistency. Between nausea, taste sensitivity, pill fatigue and complicated routines, sticking with a daily prenatal can be hard. Missed days turn into missed nutrients not because the need is unclear but because the routine is hard to maintain.

So we built one you drink. One stick, stirred into cold or room temperature water, with the DHA already in it rather than sold to you as a second purchase.

This page is the whole formula, the amount of every nutrient, and the reasoning behind each number, so you never feel like you are guessing or taking something you do not understand.

What changes when it is a drink

A prenatal is not about including everything. It is about including what matters most, in the right forms, at the right amounts, in something you can take on a bad day.

One stick
Stirred into a glass of water
A pill prenatal can ask for two capsules or eight, often with a separate DHA softgel alongside. We ask for one stick, once a day, at whatever time of day works.
Made to taste good
Because taste is what breaks the habit
Four sweeteners rather than one. Organic cane sugar for a familiar base, allulose for smoothness, Reb M for sweetness without bitterness, monk fruit to round it out. Balanced, not overpowering, at 2 g of sugar.
DHA already in it
Not a second bottle to remember
DHA is often sold as a separate softgel, which means a second purchase and a second thing to take. Ours is 250 mg of plant based algal DHA in the same stick, free from fish and shellfish allergens.
Iron included
In a form chosen for tolerance
Iron is one of the most common reasons a prenatal causes nausea, and some formulas leave it out for that reason. We use 18 mg of iron bisglycinate, a chelated form the NIH notes may cause fewer digestive side effects.
Microencapsulated
Why a powder can hold these nutrients at all
Iron, choline and DHA are the hardest nutrients to deliver well in a powder. A food grade coating keeps them stable, protects them from oxidation and holds back taste and odor until after you drink it.
No retinol
No preformed vitamin A at all
Preformed vitamin A can accumulate in the body and the NIH notes excess can be teratogenic. Because it is widely available through diet, we left it out and let food and your provider guide that intake.

Every ingredient, and why it is there

One stick pack, 9.3 g, once a day. The recommended intake column is the pregnancy RDA or Adequate Intake published by the NIH Office of Dietary Supplements, or the figure ACOG gives where they publish one.

Nutrient Form and source What we include Recommended intake
Folate Calcium L-5-methyltetrahydrofolate 600 mcg DFE 600 mcg DFE
DHA Microencapsulated algal, Schizochytrium sp. 250 mg 200 to 300 mg
Iron Microencapsulated iron bisglycinate 18 mg 27 mg
Choline Microencapsulated choline bitartrate 120 mg 450 mg
Vitamin D3 Cholecalciferol from lichen 25 mcg / 1,000 IU 15 mcg / 600 IU
Vitamin B6 Pyridoxal 5-phosphate 15 mg 1.9 mg
Vitamin B12 Methylcobalamin 6 mcg 2.6 mcg
Magnesium Magnesium bisglycinate chelate 120 mg 350 to 360 mg
Iodine Potassium iodide 150 mcg 220 mcg
Zinc Zinc gluconate 6 mg 11 mg
Vitamin K2 Menaquinone-7 75 mcg 90 mcg, no K1 and K2 split
Ginger Root extract, 5% gingerols 20 mg No RDA set
Vitamin A Not included None 770 mcg RAE
Calcium Not included None 1,000 mg

Supporting nutrients in every stick: vitamin C 100 mg, thiamin 1.2 mg, riboflavin 1.7 mg as R5P, niacin 15 mg NE, biotin 30 mcg, pantothenic acid 6 mg, selenium 60 mcg, copper 0.5 mg, sodium 180 mg, potassium 180 mg. These work behind the scenes to support absorption, balance and daily tolerance without crowding out the ingredients that matter most. Sweetened with organic cane sugar, allulose, Reb M and monk fruit. 10 calories and 2 g of sugar per stick.

Why these amounts

More is not always better. Every number in that table was a decision, and these are the ones women ask us about most. Where we sit below a published recommendation, we say so and tell you why.

Folate
600 mcg DFE, the full recommendation
More is not always better, and excess folate may offer no added benefit beyond recommended levels. We chose an amount that meets pregnancy needs precisely and a form the body can readily use.
DHA
250 mg, inside the recommended range
We include DHA at a level that aligns with pregnancy recommendations without requiring an additional fish oil supplement for most women. Microencapsulation is what lets it sit in a powder without a fishy taste or smell.
Iron
18 mg, chosen for tolerance
The pregnancy RDA is 27 mg. Iron needs rise as pregnancy progresses, but higher doses are also a common cause of nausea and digestive discomfort. We chose a gentler chelated form at an amount designed to support daily use, even on days when sensitivity is present. If your provider wants you at the full RDA, that is a conversation worth having with them.
Choline
120 mg, alongside what you eat
The adequate intake is 450 mg. Rather than including a trace amount or forcing a full daily dose into a drinkable format, we chose a meaningful amount that complements dietary intake and supports daily use. Choline is found in eggs, meat, fish, dairy and soy, so most routines are already supplying some of it.
Iodine
150 mcg, balanced rather than maximal
The recommendation is 220 mcg. Iodine requires balance, because both insufficient and excessive intake can disrupt thyroid function. We include an amount designed to help close common gaps while remaining appropriate for consistent daily use.
Vitamin B6
15 mg, above the baseline
B6 supports amino acid metabolism and nervous system function, and is commonly included in prenatal formulas above the 1.9 mg baseline. If you are treating nausea specifically, ask your provider about dosing, because clinical protocols use more than a prenatal provides.
Is this a complete prenatal?
Yes, and here is what that means
Storkling provides comprehensive daily prenatal support during pregnancy. Rather than maximizing every nutrient, we focus on those with well established pregnancy relevance, delivered for absorption, tolerance and consistency. We recommend discussing any supplement routine with your OB or midwife.

What we leave out, and why

A prenatal is not about including everything. Leaving something out is a decision too, so here is the reasoning on each one.

Vitamin A as retinol
Preformed vitamin A can accumulate in the body, and excess intake during pregnancy has been associated with potential risk. Because vitamin A is widely available through diet, we chose not to include it and instead allow intake to be guided through food and provider recommendations.
Vitamin E
Most individuals meet vitamin E needs through diet alone. Additional supplementation offers limited pregnancy specific benefit for most women.
Calcium
Calcium is commonly consumed through diet, and more importantly it competes with iron for absorption. Because iron needs are high during pregnancy, we prioritize iron delivery and allow calcium to be managed separately when needed.
Mega dosed or redundant nutrients
High doses can make a label look more complete without making the formula more useful. We intentionally avoid megadosing and nutrients already abundant in food, because excess can reduce tolerance and consistency.
Artificial colors, dyes and fillers
These do not support pregnancy nutrition and add complexity without benefit.

If you are coming off a pill prenatal

Most women who find us are not shopping for a different powder. They are leaving a capsule or a pill pack because it stopped being something they could take every day. Here is what each format asks of you.

Format What a day asks for DHA Iron
Drink mix, our format 1 stick stirred into water Included, 250 mg algal Included, 18 mg bisglycinate
Capsule prenatal 2 to 8 capsules Often a separate softgel Varies, some are iron free
Daily pill pack 4 to 5 pills, sometimes split by trimester Usually included Usually included
Gummy 2 to 4 gummies Rarely included Rarely included
Other powders and drink mixes 1 scoop or stick Varies, often sold separately Varies

Formats described in general terms, because every brand within a format is different and formulas change. Check the Supplement Facts panel on whatever you are taking now. The question worth asking is not which format looks best on paper. It is which one you will still be taking in week nine, when nothing sounds good.
