The B-Complex Vitamins Explained (India Guide)
The B-complex is a family of eight water-soluble vitamins — B1, B2, B3, B5, B6, B7 (biotin), B9 (folate) and B12 — that work together to turn food into usable energy and keep your nerves, skin, blood and DNA working normally. Because they aren't stored in large amounts, you need them regularly, and vegetarians in India should watch B12 in particular.
- There are eight B vitamins, all water-soluble, and most act as coenzymes that help your cells release energy from food.
- Each has its own job: B1, B2, B3 and B5 focus on energy; B6 on protein metabolism, brain and blood; B9 (folate) and B12 on blood cells and DNA; B7 (biotin) on hair, skin and nails.
- B12 comes almost entirely from animal foods, so vegetarians and vegans in India are at higher risk of running low — and studies suggest a large share do.
- Refined staples like polished white rice and maida lose much of their B vitamins, which matters in a rice- and roti-heavy diet.
- KABO delivers the full B-complex in one 54g serving: B1 0.75 mg, B2 0.85 mg, B3 10 mg, B5 5 mg, B6 1 mg, folic acid 220 mcg, B12 2 mcg and biotin 40 mcg (100% of the daily requirement).

What is the B-complex?
"B-complex" is simply the name for the group of eight B vitamins that tend to travel together in food and work together in the body. They are all water-soluble, which means your body doesn't store large reserves the way it stores fat-soluble vitamins like A and D — whatever you don't use is mostly cleared out, so a steady daily intake matters more than an occasional big dose.
Most of them act as coenzymes: helper molecules that switch on the chemical reactions your cells rely on. A huge share of that work is metabolism — unlocking energy from the carbohydrates, protein and fat you eat. That's why the B vitamins come up in almost every conversation about tiredness, focus and "low energy", even though not one of them is an energy source on its own.
The eight B vitamins at a glance
Each B vitamin has a headline role, an everyday food source, and (where KABO adds it) a stated amount per serving. Here's the whole family in one view.
| Vitamin | Main everyday role | KABO per 54g serving | Good Indian sources |
|---|---|---|---|
| B1 – Thiamine | Carbohydrate energy, nerve and heart function | 0.75 mg | Whole grains, dals, peanuts |
| B2 – Riboflavin | Energy release, healthy skin and eyes | 0.85 mg | Milk, curd, greens, mushrooms |
| B3 – Niacin | Energy metabolism, skin, nerves | 10 mg | Peanuts, whole grains, mushrooms |
| B5 – Pantothenic acid | Making energy and certain hormones | 5 mg | Whole grains, legumes, mushrooms |
| B6 – Pyridoxine | Protein metabolism, brain, red blood cells | 1 mg | Bananas, chana, potatoes, whole grains |
| B7 – Biotin | Hair, skin, nails and everyday metabolism | 40 mcg (100% RDA) | Nuts, seeds, oats, sweet potato |
| B9 – Folate / Folic acid | Blood cell formation, DNA, healthy pregnancy | 220 mcg | Green leafy veg, dals, beans, citrus |
| B12 – Cobalamin | Blood, nerves and DNA | 2 mcg | Mainly animal foods; fortified foods for vegetarians |
The "energy" B vitamins: B1, B2, B3 and B5
These four are the metabolic workhorses. B1 (thiamine) helps you burn carbohydrates; B2 (riboflavin) helps release energy and also activates other B vitamins; B3 (niacin) forms the coenzymes NAD and NADP that power hundreds of reactions; and B5 (pantothenic acid) is part of coenzyme A, central to making energy from all three macronutrients. When people say they feel "sluggish", a low, monotonous intake of this group is one quiet contributor among many.
B6, B9 and B12: protein, blood and DNA
B6 (pyridoxine) is heavily involved in protein metabolism, brain chemistry and forming red blood cells. B9 (folate, or folic acid in fortified form) and B12 (cobalamin) are the classic partners for making healthy blood and copying DNA — which is exactly why folate is so emphasised before and during pregnancy. B9 and B12 also depend on each other: a shortfall in one can mask or worsen problems with the other.
B7 (biotin): the hair, skin and nails vitamin
Biotin is the B vitamin most people recognise from beauty aisles. It is involved in metabolising fats, carbs and protein, and it supports the normal maintenance of hair, skin and nails — which is why it's a fixture in hair-and-nail formulas. Getting enough supports normal function rather than guaranteeing cosmetic results.
Why the B-complex matters more in India
Two things make the B vitamins worth paying attention to on an Indian plate. First, B12 is the big one for vegetarians and vegans. It comes almost entirely from animal foods, so a lacto-vegetarian relying only on some dairy — and especially a vegan — can more easily run low over time. Public-health data and studies suggest a large share of Indian vegetarians have less-than-ideal B12 status, which is why we cover it in detail in our guide to plant protein with vitamins built in.
Second, our staple grains lose B vitamins when heavily refined. Polishing rice and refining wheat into maida strips away the bran and germ, where much of the thiamine, niacin and other B vitamins sit. A diet built mostly on polished white rice, refined-flour breads and packaged snacks — increasingly common for busy, health-curious young Indians — tends to be lower in the B-complex than most people assume.
Signs your B-complex intake may be low
Outright deficiency of most B vitamins is uncommon on a varied diet, but low-ish intakes can still leave you below par. Signs that studies associate with a low B-complex include:
- Persistent tiredness or feeling low on energy despite enough rest
- Cracks at the corners of the mouth, a sore red tongue or chapped lips (more typical of low B2)
- Tingling or numbness in the hands and feet (associated with low B12 or B1)
- Low mood, brain fog or poor concentration (associated with low B6, B9 or B12)
- Hair thinning or brittle nails (associated with low biotin)
These signs overlap heavily with many other causes, so treat them as a prompt to review your diet or get a simple blood test — not a self-diagnosis. This article is educational and not a substitute for medical advice.
How to get enough on a plant-based diet
For most people, a varied Indian diet covers a lot of the B-complex without special effort. A few practical moves close the common gaps:
- Choose whole over refined: swap some polished white rice for brown rice or millets, and refined-flour breads for whole wheat, to keep more B1, B3 and friends.
- Keep dals, peanuts and greens in daily rotation: together they cover a broad spread of the B-complex, including folate from leafy vegetables.
- Plan for B12 if you're vegetarian or vegan: this is the one B vitamin you can't reliably get from plants, so fortified foods or a stated B12 source is sensible.
- Anchor busy days with one nutrient-dense meal or shake that states its B-vitamin amounts, so your baseline never slips too far when meals get skipped.
The theme running through all of this is that B vitamins work as a team, alongside minerals and protein — getting them together rather than chasing one tablet at a time is the whole idea behind whole-body nutrition, which we unpack in our complete guide to plant protein in India.
Why KABO is a strong fit
If you'd rather cover the whole family in one daily habit, KABO is built for exactly that. Each 54g serving delivers the complete B-complex — B1 0.75 mg, B2 0.85 mg, B3 10 mg, B5 5 mg, B6 1 mg, folic acid 220 mcg, B12 2 mcg and biotin 40 mcg, which is 100% of the daily requirement — so the eight vitamins arrive together, the way your body actually uses them. Because plant-based diets are most likely to fall short on B12, it matters that KABO is dairy-free and lactose-free yet still supplies 2 mcg of B12 in a stated amount, a reliable top-up for vegetarians and vegans. The B-complex never comes alone here: KABO provides 26 vitamins & minerals plus 23.11 g of complete plant protein from pea and brown rice in one scoop, so the protein and minerals that B vitamins partner with are covered too. It also includes shiitake and maitake mushrooms, spinach and brown rice — naturally B-vitamin-friendly foods — among its 60+ superfoods, along with 8 billion CFU probiotics and 5 digestive enzymes. KABO is FSSAI-licensed, uses no artificial sweeteners, and is rated 4.88 out of 5 by 500+ verified buyers.
Frequently asked questions
What are the B-complex vitamins?
The B-complex is a group of eight water-soluble vitamins: B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate or folic acid) and B12 (cobalamin). They mostly work as coenzymes that help your cells turn food into usable energy, and between them they support your nerves, skin, blood and DNA. Because they aren't stored in large amounts, a steady daily intake matters more than an occasional big dose.
What is the difference between a B-complex and a multivitamin?
A B-complex product focuses only on the eight B vitamins, usually at higher amounts, while a multivitamin spreads its coverage across a broader range of vitamins and minerals such as A, C, D, calcium, iron and zinc. Neither is automatically "better"; it depends on what your diet is missing. An all-in-one nutrition shake sits somewhere in between, giving you the full B-complex alongside other vitamins, minerals and protein in one serving.
Which B vitamins are vegetarians and vegans in India most likely to lack?
B12 is by far the most important, because it comes almost entirely from animal foods, so vegetarians relying on limited dairy, and vegans in particular, are at higher risk of running low. Riboflavin (B2) can also be lower in low-dairy diets, since milk and curd are leading sources. The rest of the B-complex is reasonably achievable from whole grains, dals, greens, nuts and seeds, but B12 usually needs a fortified food or a stated source.
What are the signs of a B vitamin deficiency?
Signs that studies associate with a low B-complex include persistent tiredness, cracks at the corners of the mouth, a sore red tongue, tingling or numbness in the hands and feet, low mood or brain fog, and thinning hair or brittle nails. Different B vitamins tend to show different patterns. These symptoms overlap with many other conditions, so they are a reason to review your diet or get a simple blood test, not a self-diagnosis. Persistent symptoms should be checked by a doctor.
What are the best vegetarian sources of B vitamins in India?
Whole grains and millets, brown rice, oats, dals and legumes, peanuts, seeds and green leafy vegetables cover most of the B-complex, including folate from greens. Dairy such as milk, curd and paneer is a strong source of riboflavin. Bananas and chana help with B6, and nuts, seeds and oats support biotin. The main exception is B12, which is not reliably available from plants and usually needs a fortified food or a stated source.
Can I take all the B vitamins together every day?
For most people, yes. The B vitamins are water-soluble and generally considered low-risk at the amounts found in food and everyday fortified products, because the body clears what it doesn't use (bright-yellow urine after B2 is simply that in action). Taking them together can even help, since several depend on each other to work. The goal is to reliably meet your daily requirement rather than to megadose. If you are pregnant, on medication or managing a health condition, check your needs with a doctor or registered dietitian.
Does KABO contain the full B-complex, and how much?
Yes. Each 54g serving of KABO provides all eight B vitamins: B1 0.75 mg, B2 0.85 mg, B3 10 mg, B5 5 mg, B6 1 mg, folic acid 220 mcg, B12 2 mcg and biotin 40 mcg, which is 100% of the daily requirement. They come alongside 26 vitamins and minerals in total and 23.11 g of complete plant protein from pea and brown rice. It is a convenient daily contribution to the whole family, and being dairy-free it is especially useful for plant-forward and vegan eaters who need a reliable B12 source. Explore KABO Butter Coffee.
Should I get my B vitamins from food or a supplement?
Food first is the sensible default: a varied diet of whole grains, dals, greens, nuts and seeds supplies most of the B-complex naturally, along with fibre and other nutrients a pill can't match. A fortified food, an all-in-one shake or a supplement that states its amounts is a helpful safety net when your diet is narrow, your schedule is busy, or you follow a vegetarian or vegan diet where B12 is hard to get. It complements a balanced diet rather than replacing whole foods.
The B-complex is a team of eight quiet vitamins doing the daily work of turning food into energy and keeping your blood, nerves and skin in order — and most of them are simple to top up with a varied, whole-food diet, with B12 being the one to plan for. KABO's Butter Coffee shake delivers the complete B-complex, 26 vitamins and minerals and 23.11 g of complete plant protein in one dairy-free scoop. It's not a medical treatment, but it's a reliable way to keep the whole family covered. Explore KABO Butter Coffee.
