Vegan Vitamins & Supplements Buying Guide

Introductory note: I’ve created this page to help you find the best deals on exactly the vegan vitamins you need. On the one hand, some people blow huge amounts of money on useless and overpriced vitamins. But on the other hand, well-chosen supplements offer a reliable and inexpensive way to avoid nutrient deficiencies.

In researching this page, I’ve spent hours and hours combing to find the products of greatest interest to vegans. In all cases, I comparison shopped to find the vegan offerings that deliver the greatest bang for the buck. These are exactly the products I buy for myself. Neither I nor receive any endorsement money from any of these brands. Anytime I discover a better deal than what I’m currently linking to, I update the recommended product accordingly. I am confident you’ll find this page of value anytime you need to replenish your supplements.— Erik Marcus, publisher.

What are the Most Important Vitamins for Vegans?

Vegans and omnivores alike should be on guard against nutrient deficiencies. For vegans, a well-planned diet can go a long way toward avoiding the most common pitfalls. That means plenty of vegetables, whole grains, beans, and fruit—plus a small amount of nuts or seeds each day. But even with all this taken care of, some vegans will fall short on a few key nutrients, especially B12, Vitamin D, calcium, iodine, protein, and zinc.

This guide brings together key information about supplements that are of special interest to vegans.

Vegan Vitamin B12

If you research Vitamin B12 online, you will likely encounter a massive cloud of potentially dangerous misinformation. Here is what you need to know:

The only vegan foods that reliably contain significant amounts of B12 are those that have been fortified with lab-cultured B12. And because people vary greatly in their ability to absorb B12, it’s quite possible to be low or deficient even if you consume 100 percent of the U.S. RDA every day. We therefore recommend that everyone get their blood tested occasionally, and adjust their supplement regimen if B12 levels fall below 500 pg/mL. Some people, particularly those over age 60, absorb this nutrient so poorly that regular B12 injections are prudent.

Sublingual B12 Supplements are the Best Choice

B12 deficiencies cause a variety of health problems, including potentially irreversible nerve damage that often occurs before noticeable symptoms arise. The easiest way for most people to avoid a deficiency is to take a B12 supplement containing at least 1000 micrograms of B12 two or three times a week. The best B-12 supplements are lozenges or tablets that are labeled “sublingual.” Let the lozenge or tablet sit under your tongue to dissolve—the B12 will be absorbed by your mouth’s capillaries more efficiently than if you swallowed the dose. While side effects are extremely rare, consult your physician before taking more than about 7,000 micrograms of B12 per week. There are other forms of B12 supplements like nasal sprays, but nothing compares to sublinguals when it comes to purchasing highly absorbable B12 for the best price.

There are two different B12 molecules used by the supplement industry: cyanocobalamin and methylcobalamin. Some people are adamant that methylcobalamin is best, but clinical evidence currently leans toward cyanocobalamin being the better choice (although either molecule will probably be fine). I personally buy Now’s 1000 mcg cyanocobalamin lozenges, since they offer the biggest bang for the buck in terms of dosage and number of tablets. Most vegans can cover their B12 needs by taking one tablet every couple of days.

Vegan Vitamin D

Vitamin D usually comes from one of three sources:

  1. by exposing your skin to direct sunlight
  2. through drinking fortified milks (vegan or cow’s)
  3. via supplements

Most people, both vegans and omnivores, can benefit from Vitamin D supplements. Unfortified foods do not provide Vitamin D.

Even though exposure to sunlight will generate Vitamin D, you’re probably better off taking a supplement. That’s because your body requires strong direct sun exposure on most of your skin to produce sufficient Vitamin D. This is impossible during winter months in temperate climates since even if you bare your skin despite the cold, the sun will be too low in the sky to provide sufficient Ultraviolet B rays to generate the vitamin. Also, exposing skin to direct sunlight leads to premature wrinkles and aging.

Until recently, no company offered a vegan version of vitamin D3 (the most common vitamin D molecule). Vegans had to buy the less potent and more expensive vitamin D2. But over the past few years, several vegan D3 brands have come to market. Pure and Essential’s Vegan Vitamin D3 is the most economical product we have found, and it comes in easy-to-swallow vegan capsules.

Our vitamin D page offers extensive coverage of this topic.


The good news for vegans is that most brands of soy or almond milk contain more calcium than cows’ milk—of course you’ll want to check the label to confirm your favorite brand packs a sufficient dose of calcium. Drinking these products daily and regularly eating tofu that lists calcium sulfate in its ingredients can go a long way towards ensuring adequate calcium intake. Kale offers another excellent source of calcium, and it’s packed with other important nutrients too. Beans vary widely in the amount of calcium they contain, with soybeans and white beans offering the most.

If you don’t consume much calcium-rich vegan milk, beans, greens, or tofu, it can be hard to meet the US RDA of 1000 milligrams per day. If your daily food choices fall short of the RDA for calcium, a supplement can help. Some calcium supplements are made from oyster shells (the vegan status of these supplements is debatable, though, since often “oyster shell” supplements are mined from oysters who died decades or centuries ago). More problematically, many calcium supplements either contain lanolin-derived vitamin D, or they come in gelatin capsules or as tablets with non-vegan coatings.

But you’re not at all out of luck if you decide to supplement. Perhaps the best choice is Deva’s Vegan Calcium with Magnesium. Each tablet contains about a third of the RDA for calcium, so it’s a convenient way to close the gap. Plus, this brand includes vegan vitamin D, which can aid calcium absorption.

Protein Powders

One of the only good things you can say about meat and eggs is that they’re full of protein. So if you remove these foods from your diet you’ve got to pick up the slack with other protein-rich foods.

Adults should consume, on a daily basis, about one gram of protein per kilogram of body weight. On top of this, much of this protein should come from lysine-rich foods like beans, nuts, seeds, and quinoa. One way to help ensure you’re getting sufficient protein is to get into the habit of choosing meals that contain at least one protein-rich item. If, for whatever reason, you find you’re still coming up short—or you don’t eat many lysine-rich foods—a vegan protein powder is a great way to make up the difference.

Many of the hardest-to-digest vegan foods are those that are richest in protein—particularly beans and wheat gluten. So vegan protein powder makes a great alternative. Just one scoop mixed into water provides nearly the amount of protein as an entire 16-ounce can of beans!

Amazon carries all the top brands of vegan protein powder. Our favorite is Orgain Organic Protein Powder in vanilla or chocolate. Orgain’s protein powder contains the same high-quality organic ingredients found in premium brands costing twice the price. Plus it also packs in some omega-3s thanks to organic chia seeds. If you decide to give protein powder a try, we highly recommend also buying a 16-ounce shaker bottle. These bottles are usually tough to find in the 16-ounce size because shaker bottles are primarily used for electrolyte drinks that are consumed in larger amounts.

Omega-3 and DHA

There is excellent reason to include omega 3 fats in your diet. While these fats are abundant in cold-water fish, there are also excellent vegan sources of omega 3. These include:

  • walnuts
  • chia seeds
  • flax
  • hemp
  • pumpkin seeds

Of these, walnuts and chia are the richest sources of omega 3. You can significantly raise your omega 3 consumption by eating a dozen or so walnut halves a day. A tablespoon of chia per day will also give you sufficient omega 3.  Adding a tablespoon of chia to your smoothies is probably the easiest way to include this food in your diet. There are numerous other ways you can take chia. Nutiva organic raw chia seeds are inexpensive and available from

DHA and EPA Fatty Acids

Even if you consume plenty of Omega-3s, your body may not sufficiently convert these fats to DHA and EPA. Fortunately, there are several DHA/EPA supplements on the market. Of all supplements of special interest to vegans, these are probably the most expensive. That’s because the vegan brands are derived from algae rather than fish. But not only is vegan DHA/EPA more humane and eco-friendly, because it’s sourced lower on the food chain you’ll be exposed to less mercury and other heavy metals. Prices have recently dropped significantly on these supplements as the market for vegan DHA/EPA has expanded and become more competitive. However, they’re still by far the most expensive supplement you’re likely to take.

The cheapest vegan DHA/EPA that we’ve found (measured by multiplying capsules per bottle and dosage per capsule and dividing that figure into the price per bottle), are Amala Vegan Omega 3 and Testa Omega 3 Algae Oil. You can find cheaper brands with the same number of capsules per bottle, but nearly all of them carry a much smaller dosage. If you live in a hot climate, order these capsules during cooler months to prevent exposure to heat during shipment.


If you follow a well-planned vegan diet, you’re probably getting abundant amounts of most nutrients a multivitamin provides. But a few nutrients may fall through the cracks, so a vegan multivitamin can be advisable. Few vegan foods are good sources of zinc or iodine. So for many vegans these two nutrients are reason enough to take a multivitamin.

Multivitamins typically 100 percent of the B12 RDA. But keep in mind that a multivitamin alone may not provide sufficient amounts of this nutrient. Many people won’t absorb sufficient amounts from a daily tablet containing 100 percent of the US RDA.

Avoid buying a multivitamin that contains iron unless your doctor recommends it based on blood work. With supplements, it’s easy to push your iron intake past recommended levels. And taking in too much iron can be as hazardous as taking too little.

Deva’s Tiny Tablet Vegan Multivitamin is a solid and cost-effective choice.


Iron is abundant in a number of vegan foods including leafy green vegetables, seaweed, and some types of beans. That said, it can be a challenge for some people, especially women of child-bearing years, to obtain sufficient iron. You can easily meet these needs with iron supplements, or through a multivitamin that includes iron.

Iron is one a nutrient that is harmful if consumed in excesss. So it’s probably best not to take iron supplements except on the advice of your doctor based on your bloodwork. One of the most affordable vegan iron supplements on the market is Deva’s Vegan Chelated Iron.

Note that vitamin C can significantly increase iron absorption, either when taken along with an iron supplement or ingested together with an iron-rich food. You don’t need to buy a Vitamin C supplement for this; a squeeze of lemon taken in water alongside your iron will do the trick.


Since children are often less likely than adults to eat with nutrition in mind, a multivitamin can safeguard against deficiency. VegLife makes a chewable Vegan Kids Multiple that’s formulated to match the nutritional needs of children.


If ever there was a time to be on guard against deficiency, it’s during pregnancy. Deva’s Prenatal Multivitamin is specifically formulated to cover the needs of expectant mothers. In addition to what a multivitamin can provide, you need to pay particular attention to calcium and DHA. For extensive information on prenatal nutrition, please see our Vegan Pregnancy Guide.
