A well-planned vegan diet covers a lot of ground. Fruits, vegetables, legumes, whole grains, nuts, and seeds deliver fiber, antioxidants, and phytonutrients that many omnivores miss. But "well-planned" is doing a lot of work in that sentence. Certain nutrients are difficult — sometimes impossible — to get in adequate amounts from plant foods alone.
This isn't a critique of veganism. It's biochemistry. Some vitamins occur primarily or exclusively in animal-derived foods, and supplementation is a practical solution for filling those gaps. Gummy vitamins make that process easier, tastier, and more consistent — as long as the gummies themselves are vegan. (Spoiler: many aren't.)
Here's a breakdown of the nutrients most commonly lacking in vegan diets, how gummy vitamins can help, and what to look for when choosing supplements that align with your values. For a broader overview of gummy vitamin formats, check our complete guide to gummy vitamins.
The Nutrients Vegans Are Most Likely to Miss
The Academy of Nutrition and Dietetics acknowledges that vegan diets are nutritionally adequate when appropriately planned — but they also specifically flag several nutrients that require attention. Let's go through them.
Vitamin B12
This is the big one. Vitamin B12 is produced by bacteria and found almost exclusively in animal products: meat, fish, dairy, and eggs. There is no reliable plant food source of B12 in its active form. Nutritional yeast and some fermented foods contain small amounts, but they're inconsistent and insufficient for meeting daily requirements.
B12 deficiency is not a minor issue. It can lead to megaloblastic anemia, neurological symptoms (tingling, numbness, memory problems), and irreversible nerve damage if left untreated. Studies show that up to 86% of vegans who don't supplement have low B12 levels, depending on the population studied.
The recommended daily amount for adults is 2.4 mcg. Because absorption decreases as dose size increases, many experts recommend higher supplemental doses — 250 to 1000 mcg daily — to ensure adequate uptake. Our Vitamin B12 Gummies → deliver 1000 mcg of methylcobalamin (the bioactive form) per serving. Methylcobalamin doesn't require conversion by the body, making it more directly usable than cyanocobalamin, the synthetic form found in many cheaper supplements.
Vitamin D
Vitamin D is tricky for everyone, not only vegans. Your skin produces it from UVB sunlight, but factors like latitude, skin tone, sunscreen use, and time spent indoors mean that deficiency is widespread — affecting an estimated 42% of U.S. adults. Dietary sources include fatty fish, egg yolks, and fortified dairy — none of which appear in a vegan diet.
Vitamin D comes in two supplemental forms: D2 (ergocalciferol, plant-derived) and D3 (cholecalciferol, traditionally from lanolin in sheep's wool). Vegan D3 sourced from lichen has become available in recent years and appears to be equally effective at raising blood levels. When choosing a gummy, check whether the D3 source is lichen-derived if this matters to you.
Omega-3 Fatty Acids (EPA and DHA)
Flaxseeds, chia seeds, and walnuts provide ALA (alpha-linolenic acid), a short-chain omega-3. But your body converts ALA to EPA and DHA — the long-chain omega-3s your brain and heart need — at a rate of roughly 5-10% for EPA and less than 1% for DHA. That's a significant bottleneck.
Fish get their omega-3s from algae. Algae-based DHA/EPA supplements cut out the middlefish and provide these fatty acids directly from the original source. Some gummy vitamins now include algal omega-3s, though the doses tend to be lower than what you'd get from a standalone algae oil supplement.
Iron
Plant foods contain non-heme iron, which your body absorbs at roughly 2-20% efficiency — compared to 15-35% for the heme iron in meat. Vegans often have similar iron intake to omnivores but lower iron stores (ferritin levels) because of this absorption difference. Pairing iron-rich foods with vitamin C can increase non-heme iron absorption by up to 6x, which is one reason a daily Vitamin C supplement → can be a smart addition to a vegan routine.
Zinc, Iodine, and Calcium
These three deserve a mention. Phytates in whole grains and legumes can reduce zinc absorption. Iodine intake depends heavily on whether you use iodized salt (sea salt and pink Himalayan salt don't contain it). And while calcium-rich plant foods exist (kale, bok choy, fortified plant milks), many vegans fall below the 1000 mg daily recommendation. A well-formulated multivitamin can help cover these bases.
Why Most Gummy Vitamins Aren't Vegan (and How to Tell)
The majority of gummy vitamins on the market use gelatin as their base. Gelatin is derived from collagen — typically from pork skin or beef bones. It gives gummies their chewy texture, and it's cheap to manufacture. It's also, obviously, not vegan.
The vegan alternative is pectin, a polysaccharide found in fruit cell walls (especially apples and citrus peels). Pectin-based gummies have a slightly different texture — a bit softer, less bouncy — but they deliver nutrients the same way. Some brands also use starch or carrageenan as gelling agents.
Here's what to check on the label:
- Ingredients list: Look for "pectin" or "fruit pectin" instead of "gelatin."
- Certification: Look for vegan certification logos (Vegan Action, Vegan Society) for extra assurance.
- Colorants: Carmine (a red dye from crushed cochineal insects) shows up in some gummies. Look for fruit and vegetable juice concentrates as coloring instead.
- Vitamin D3 source: If the label lists cholecalciferol, check whether it's from lanolin (sheep-derived) or lichen (vegan).
- Sugar coating: Beeswax is sometimes used as a glazing agent on gummies. Look for carnauba wax (plant-derived) as the alternative.
At GMMY, every product we make is pectin-based, vegan, and cruelty-free. We don't use gelatin, carmine, beeswax, or animal-derived D3. When we say vegan, we mean every ingredient — not "mostly vegan with a gelatin asterisk."
Building a Vegan Supplement Routine With Gummies
You don't need a dozen bottles on your counter. Here's a practical approach to covering the most common vegan nutrient gaps:
The Non-Negotiable: B12
Every major dietetic organization that endorses vegan diets also recommends B12 supplementation. This isn't optional. If you take one supplement, make it this one. Our Vitamin B12 Gummies → cost $25 for a one-month supply — under $1 a day for a nutrient your nervous system depends on.
The Daily Foundation: Multivitamin
A good vegan multivitamin catches the nutrients you might miss even with a varied plant-based diet: vitamin D, zinc, iodine, and sometimes selenium. Our Multivitamin Gummies → cover a broad range of daily nutrients and pair well with a standalone B12 supplement. At $25/bottle, that's two supplements for $50/month — $1.67 a day for complete daily coverage.
The Immune Supporter: Vitamin C
Most vegans get plenty of vitamin C from fruits and vegetables. But if you're supplementing iron (non-heme), adding extra vitamin C can meaningfully improve absorption. Our Vitamin C Gummies → taste like real oranges and deliver a consistent daily dose alongside your meals.
The Add-On: Algal Omega-3
If you're not regularly eating large amounts of walnuts, flax, and chia, an algal DHA/EPA supplement is worth considering. GMMY doesn't currently offer an omega-3 gummy, but we recommend looking for one with at least 250 mg combined DHA/EPA from algal sources.
Common Mistakes Vegans Make With Supplements
After talking with thousands of customers who follow plant-based diets, we see these patterns repeatedly:
Assuming fortified foods are enough. Fortified plant milks, cereals, and nutritional yeast can contribute to B12 and vitamin D intake, but the amounts vary by brand and serving size. Relying on them as your primary source requires careful tracking that most people don't maintain long-term. A daily supplement is more reliable.
Buying the cheapest option without checking the form. Cyanocobalamin (the most common form of B12 in cheap supplements) requires your body to convert it to methylcobalamin before it can be used. Most people handle this fine, but those with certain genetic variants may not convert it efficiently. Methylcobalamin cuts out that step.
Ignoring symptoms because "my diet is healthy." A plant-rich diet is healthy in many ways. It can still leave you deficient in specific nutrients. Fatigue, brain fog, mouth sores, and tingling in your hands or feet are all worth investigating with a blood test — even if you eat well. Get your B12, vitamin D, and ferritin levels checked at your annual physical.
Taking iron "as a precaution" without testing first. Iron is one supplement you should not take blindly. Excess iron can cause oxidative damage and GI distress. Get your levels tested before supplementing, and let your doctor determine the appropriate dose. Vitamin C supplementation to improve dietary iron absorption is a gentler first step.

Frequently Asked Questions
How can I tell if a gummy vitamin is vegan?
Check the ingredients list for gelatin (not vegan), carmine (insect-derived red dye), and beeswax (used as a coating). Vegan gummies use pectin or starch as the base, fruit/vegetable juice for color, and carnauba wax for coating. Third-party vegan certifications provide additional confirmation. All GMMY gummies are pectin-based, vegan, and cruelty-free.
Do vegans need to supplement B12 even if they eat nutritional yeast?
Yes. While fortified nutritional yeast contains B12, the amount varies by brand, and most people don't consume enough daily to meet the 2.4 mcg recommendation consistently. B12 is water-soluble and non-toxic at high doses, so supplementing provides a reliable safety net regardless of dietary intake. The risk of deficiency far outweighs any downside of supplementation.
Is methylcobalamin better than cyanocobalamin?
Methylcobalamin is the bioactive form of B12 — your body can use it directly without conversion. Cyanocobalamin is synthetic and must be converted before use. Both forms are effective for most people, but methylcobalamin may be preferable for individuals with MTHFR gene variants or those who want to skip the conversion step. GMMY uses methylcobalamin in our B12 gummies.
Can I get enough protein and iron on a vegan diet without supplements?
Protein: yes, with intentional planning. Legumes, tofu, tempeh, seitan, and quinoa are all strong plant protein sources. Iron: it depends. Plant-based (non-heme) iron is absorbed less efficiently than heme iron from meat. Many vegans maintain adequate iron levels through diet alone, especially when pairing iron-rich foods with vitamin C. However, menstruating individuals, athletes, and pregnant people may need supplementation. A blood test is the best way to know.
Should vegan kids take different supplements than vegan adults?
Vegan children have the same nutrient gaps as adults (B12, vitamin D, omega-3s) but in age-appropriate doses. Children's gummy vitamins typically contain lower amounts per serving. Consult a pediatrician or registered dietitian familiar with plant-based diets to determine the right supplements and dosages for your child's age and size. For more on kids' gummy vitamins, read our parent's guide to kids' gummies.
