Since I’ve sadly outgrown the Flintstones Chewables stage of life, ensuring that I’m getting all of my essential vitamins can sometimes feel like a guessing game.
As a dietitian, patients often ask me about taking vitamin supplements to address any potential deficiencies that they may have.
Fortunately, we can get the majority of our nutrients from whole foods like fresh produce, rather than relying on pills and powders.
Nutrients in the B-vitamin group play several vital roles in maintaining our bodily functions. Many of the vegetables that we eat every day – and may even have growing in our gardens – can supply an ample amount of B vitamins.
We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission.
So, what are B vitamins exactly, and which types of veggies should you choose to grow at home to ensure that you’re getting enough of these essential nutrients? Let’s take a look.
What You’ll Learn
What Are B Vitamins?
There are many different B vitamins, each with their own number and name. As a group, they generally support metabolism and energy production.
Each of the eight major B vitamins described here has its own unique roles to play in the body as well.
Note that there are several other substances in the B family (B4, B10, and B20, for example) but these are not considered to be vitamins and therefore they are not included in this article.
This portion of the article is broken down into parts, to showcase each of the B vitamins in all of its glory. You’ll learn how each one helps to support our health, and where to find it in the garden.
Each vitamin described below also has the DV or Daily Value listed, which is the FDA-defined amount considered sufficient to meet the needs of the general, healthy adult population.
If you have specific health concerns, please talk to your doctor about recommended amounts to meet your needs.
B1 – Thiamin
Thiamin is useful in conversion of the food we eat into energy, and helping with nervous system functions.
It also helps to metabolize fats and some types of drugs.
DV: 1.2 milligrams (mg) daily. One-half cup of black beans contains about 0.4 mg of thiamin.
B2 – Riboflavin
Riboflavin helps our bodies to convert food into energy, aids the formation of red blood cells, and assists in overall growth and development.
Where to find it in the garden: Mushrooms and spinach.
DV: 1.3 mg daily. One-half cup of grilled portobello mushrooms contains 0.3 mg of riboflavin.
B3 – Niacin
Niacin assists with the production of cholesterol, aids digestion, assists in converting foods into energy, and supports nervous system function.
Where to find it in the garden: Mainly found in meats and whole grains, it can also be found in beans!
Raw tomatoes have a small amount of niacin, and more concentrated processed tomato products can be good sources.
And yes, we know that tomatoes and a few other “veggies” mentioned in this article are technically fruits, but for the sake of simplicity I’m focusing on what we typically consider to be vegetables in our diet.
DV: 16 mg daily. One cup of marinara sauce contains 10.3 mg, and 1/2 cup of lentils contains 1 mg of niacin.
B5 – Pantothenic Acid
B5 plays a role in various processes, including converting the foods we eat into energy (noticing a trend here?), metabolizing fats, producing hormones, and forming red blood cells.
Where to find it in the garden: Peas, beans, broccoli, mushrooms, avocados, and sweet potatoes.
DV: 5 mg daily. Half of an avocado contains 1 mg, and 1/2 cup cooked broccoli contains 0.5 mg.
B6 – Pyridoxine
Pyridoxine assists with immune function, nervous system function, metabolism, and red blood cell formation.
Where to find it in the garden: Chickpeas and potatoes. And despite what your parents may have told you, not all of a potato’s nutrients are in its skin.
While the skin is the biggest source of fiber, the potato flesh contains over 50% of the nutrients. For the maximum benefit, I still recommend including the skin when cooking.
B6 is also found in many fruits, but again, we are focusing on our veggies today.
DV: 1.7 mg daily. One cup of chickpeas contains 1.1 mg of pyridoxine – over half your day’s worth!
B7 – Biotin
Biotin plays vital roles in energy storage and metabolism.
Where to find it in the garden: Avocado, cauliflower, sweet potatoes, broccoli, and it’s also found in many fruits.
DV: 30 micrograms (mcg) daily. For reference, a microgram is 1/1000th of a milligram. One-half cup of cooked sweet potato has 2.4 mcg of biotin.
B9 – Folate
Folate aids protein metabolism and red blood cell formation. It is essential in the diets of pregnant women, to prevent birth defects.
Where to find it in the garden: Asparagus, avocado, beans and legumes (notably lentils, black-eyed peas, and pinto beans), peas, and leafy green vegetables.
DV: 400 mcg daily. One-half cup of cooked spinach contains 131 mcg, and the same amount of black-eyed peas offers 105 mcg.
B12 – Cobalamin
Cobalamin plays a part in conversion of food to energy, nervous system function, and red blood cell formation. When B12 reaches the small intestine, it combines with a special protein called intrinsic factor that allows it to be properly absorbed.
A lack of this intrinsic factor can result in a condition called pernicious anemia, a type of B12 deficiency.
Where to find it in the garden: B12 is difficult to find in plant products outside of fortified cereals. It is produced by bacteria, not plants or animals.
Animals are able to retain the B12 produced from bacteria in their gut and store it in their liver and muscles.
They may also obtain B12 from eating other animals or animal products. Due to this, the main food sources for humans are meats, seafood, dairy, and eggs.
Those following a vegan or plant-based diet are encouraged to take a B12 supplement or add fortified foods to their diet.
There are many different forms of B12 – including cyanocobalamin, methylcobalamin, and hydroxycobalamin – that you may see listed on supplements or fortified foods. These forms can all be absorbed by the body and are effective in preventing deficiency.
DV: 2.4 mcg daily. Again, you probably will not find this in any garden veggies. A 3-ounce serving of canned tuna fish will give you 2.5 mcg. Some great options for those who follow a plant-based diet (and omnivores as well!) are fortified nutritional yeast or breakfast cereal.
