What Are B-Vitamins And Where To Find Them In Your Food

A family of eight

B-vitamins are a group of eight water-soluble vitamins. They were discovered at different times and, for a while, were thought to be a single substance, which is why they share a letter. Later research separated them and gave each its own number.

Because they dissolve in water, B-vitamins belong in the same broad category as vitamin C. Nutrition references classify each of them as an essential nutrient, meaning people obtain them from food or supplements.

Supplement labels sometimes use the term B-complex for a product that includes several or all of them. Gelagen, according to the brand, names five of the eight, and this guide will point those out as we go.

If you have ever stared at a shelf of products that say B-complex, B-50 or B-something and wondered what the letters mean, this guide is for you. It is a vocabulary lesson, a grocery tour and a label primer in one.

The eight, with their other names

The numbering skips around, and each vitamin has a chemical name that appears on labels. Here is the full roster:

Notice that the numbers are not consecutive. Some candidates for numbers six, eight, ten and eleven were later reclassified or dropped, which is why the series appears to skip. Biotin, for instance, was originally called vitamin H before it was folded into the B family as B7.

• B1, thiamin
• B2, riboflavin
• B3, niacin
• B5, pantothenic acid
• B6, pyridoxine and related forms
• B7, biotin
• B9, folate, with folic acid as the added form
• B12, cobalamin, including methylcobalamin

Where to find them in everyday food

The good news is that B-vitamins are spread throughout the grocery store. No single food has all eight, but a varied plate usually touches many of them.

Some broad patterns from food composition tables are helpful to know. Whole grains, legumes, eggs and dairy appear in several entries. Leafy greens are a classic folate source. Animal foods are the main natural source of B12, and fortified cereals and plant milks add it to the plant-based side of the aisle.

If you want a one-line summary, it is this: eat a wide range of foods and the family takes care of itself on the grocery side. The more colors and textures on the plate, the more entries on the list you are likely to touch.

A food-group tour

Here is a quick tour of food groups and the B-vitamins commonly associated with them in nutrient databases:

These pairings come from general food composition tables, and they are broad strokes rather than precise accounting. Individual foods vary, and the best use of the list is as inspiration for shopping and cooking, not as a scorecard.

• Whole grains and oats: thiamin, niacin, pantothenic acid, biotin
• Legumes such as lentils and chickpeas: thiamin, folate, vitamin B6, biotin
• Leafy greens and asparagus: folate
• Eggs: riboflavin, biotin, pantothenic acid, vitamin B12
• Dairy foods: riboflavin and vitamin B12
• Fish and poultry: niacin, vitamin B6, vitamin B12
• Mushrooms: riboflavin, niacin, pantothenic acid
• Nuts and seeds: biotin, vitamin B6, pantothenic acid

Reading B-vitamins on a label

On a Supplement Facts panel, B-vitamins are listed by name, usually in order, with a quantity per serving and sometimes a percent Daily Value. Where a nutrient comes in several forms, the form is added in parentheses.

A few label terms worth knowing: niacin may be written in niacin equivalents, folate uses Dietary Folate Equivalents, and several vitamins are listed in micrograms rather than milligrams. If you check the unit, the numbers on two bottles become easy to compare.

On a food label, fortified means a nutrient was added during manufacturing. Many cereals and plant milks list added B-vitamins this way.

One further label term is Daily Value, a reference used on labels to put nutrients on a common scale. It is a labeling device for comparing products and is not tailored to any one person.

Which five are named in Gelagen

Gelagen is a berry-flavored daily gummy dietary supplement that the brand markets as a skin-support gummy with B-vitamins. According to the brand, the named ingredients are Biotin (B7), Vitamin B12 (as methylcobalamin), Vitamin B6 (as pyridoxine hydrochloride), Folate (B9), and Pantothenic acid (as d-calcium pantothenate, B5).

That is five of the eight. Thiamin, riboflavin and niacin are not among the ingredients the brand names. The exact amounts of those five appear in the Supplement Facts on the bottle.

Each bottle holds 60 gummies, with a suggested use of 2 gummies daily, about 30 minutes before a morning or afternoon meal with a full glass of water, never exceeding the label amount.

The brand's materials describe Gelagen as a daily routine item, and the label is where to confirm each named nutrient and its form.

Putting it together in your routine

If you enjoy cooking, a colorful plate is a pleasant way to meet many of the foods above. Oatmeal with seeds, a lentil salad with greens, eggs with roasted sweet potato and a yogurt snack already span a good part of the B-vitamin family.

A supplement is a separate and optional layer. Gelagen is a one-time purchase with no subscription, offered in packs of 2, 3 or 6 bottles, with free shipping shown on all packs and a 60-day money-back guarantee. Whatever you choose, knowing the names behind the letters makes every label easier to read.
