Sabja Seeds vs Chia Seeds: Differences, Nutrition and How to Use Them

Medically reviewed by Dr. Reina Punj, MBBS, PG Diploma in Endocrinology (University of South Wales), Lead Physician, Excelgenics Clinical Panel.

Sabja seeds vs chia seeds: the two look alike once soaked, but they come from different plants and have very different amounts of research behind them. Sabja (tukmaria) is the seed of sweet basil, while chia is the seed of Salvia hispanica. Chia has well-measured nutrition data and is a rich plant source of the omega-3 fat ALA; sabja has far less reliable data, so there is no evidence-based answer to "which is better".

Both are traditional or popular additions to Indian drinks and desserts, and both swell into a gel in water. This guide compares their nutrition per tablespoon, explains what is and is not known, shows how to soak and use each, and covers who should take care.

Sabja seeds vs chia seeds at a glance

Sabja seeds vs chia seeds in Hindi: what are they called?

In Hindi, sabja seeds are called sabja or tukmaria (also written tukmariya). They are the seeds of sweet basil, not of tulsi (holy basil, Ocimum tenuiflorum), which is a related but different plant. Chia has no traditional Hindi name and is usually sold simply as chia seeds or chia beej. Because both seeds look similar after soaking, people often mix them up, so check the pack for the plant name.

Nutrition per tablespoon

The figures below are for chia, from USDA FoodData Central (dried chia seeds), worked out for one level tablespoon of about 14 g (two tablespoons weigh about 28 g).

Spoon sizes vary, so treat these as approximate. We could not find sabja in the Indian Food Composition Tables (IFCT 2017) or USDA FoodData Central, so there is no comparable per-tablespoon figure. In published laboratory analyses of basil seeds, fat ranged from about 10 to 33 g per 100 g and dietary fibre from about 7 to 26 g per 100 g, depending on the variety, growing conditions and storage.

Omega-3: chia is a well-measured source of ALA

Chia is one of the richer plant sources of alpha-linolenic acid (ALA), the omega-3 fat found in plants. A tablespoon provides about 2.5 g. For comparison, ICMR-NIN suggests Indians aim for about 2.2 g of omega-3 fats a day, and the US adequate intake for ALA is 1.1 g for women and 1.6 g for men. The body converts only a small share of ALA into the longer-chain omega-3s EPA and DHA, so chia is not a replacement for oily fish or algae oil. Our Vegan Omega-3 Supplements Guide explains the difference.

For sabja, the honest answer is that we do not know how much ALA a spoonful provides. A 2021 review of basil seed research found that ALA made up anywhere from 0.3% to about 66% of the seed oil in different studies, and total fat itself varied several-fold. Some samples are clearly rich in ALA, but the data are too variable to give a reliable figure, and claims that sabja has "more omega-3 than chia" are not supported.

Fibre and the gel

Both seeds form a gel because their outer layer contains mucilage, a type of soluble fibre. Chia's fibre is mainly insoluble fibre plus mucilage. In basil seeds, mucilage makes up roughly 17–20% of the seed. This gel is what gives falooda and chia pudding their texture. If you are not used to high-fibre foods, start with a small amount and drink enough water.

How to use sabja and chia seeds

Sabja (tukmaria)

• Soak first: traditionally, about a teaspoon of seeds is soaked in a glass of water until each seed has a soft, translucent coat.
• Use: stir into falooda, rose or khus sherbet, nimbu pani, coconut water or chilled milk.
• Check the soak: make sure no dry clumps remain before drinking.

Chia

• Soak first: mix with water, milk or curd and leave for about 15–20 minutes until it turns into a soft gel. Chia can absorb up to about 10 times its weight in liquid.
• Use: chia pudding, overnight oats, smoothies, raita or a spoonful stirred into dal or khichdi just before serving.
• Whole or ground: chia is absorbed well whole, so grinding is optional.

ICMR-NIN's 2024 dietary guidelines list basil seeds and chia seeds, along with flax, fenugreek and amaranth seeds, among seeds that can be eaten at least three to four times a week as part of a balanced diet.

Choking caution and who should be careful

Seeds that swell can be a hazard if swallowed dry. In 2014, US doctors reported a case in which dry chia seeds swelled and blocked a patient's food pipe (oesophagus), and the seeds had to be cleared during an endoscopy. For chia, that means:

• Never eat dry chia seeds on their own.
• Soak fully so the seeds have finished swelling before you eat or drink them.
• Swallowing problems: people with difficulty swallowing or a known narrowing of the oesophagus should take particular care and ask their doctor.
• Children: give only fully soaked seeds, in small amounts, under supervision.
• Pregnancy and medical conditions: we found no studies of sabja in pregnancy. Normal food amounts are a sensible limit; if you are pregnant, take medication or have a digestive condition, check with your doctor before eating either seed regularly.
• Get help if food seems stuck, especially if you cannot swallow your own saliva.

Sabja seeds vs chia seeds: which is better?

Neither seed is "better" across the board. Choose based on what you want from it:

• If you want a measured source of plant omega-3 and fibre: chia, because its nutrition has been reliably analysed. A tablespoon covers the daily ALA adequate intake for most adults.
• If you want a cooling, traditional addition to drinks: sabja is familiar, widely sold in Indian shops and suits sherbets and falooda well. Just do not rely on it for a specific amount of omega-3.
• If you want variety: there is no reason not to use both, as part of a balanced diet. If you are comparing chia with alsi, see our guide to chia seeds vs flax seeds.

Neither seed should be relied on to treat or prevent any health condition. Claims online about weight loss, blood sugar or "body cooling" for sabja come mainly from traditional use, laboratory work and animal studies, not from good-quality human trials.

Frequently asked questions

Are sabja seeds and chia seeds the same?

No. Sabja (tukmaria) comes from sweet basil and chia comes from Salvia hispanica. They look similar when soaked, but they are different plants with different nutrition data.

Which has more omega-3, sabja or chia?

Chia provides about 2.5 g of ALA per tablespoon. Reliable figures for sabja do not exist: published analyses of basil seed oil vary enormously, so no fair comparison is possible.

Can I eat sabja or chia seeds without soaking?

It is safest not to. Dry chia seeds should not be eaten on their own because they swell, and sabja is normally soaked before use. Chia can be sprinkled on moist food such as curd, but soaking is the safer default.

How much sabja or chia can I have in a day?

There is no official limit. One to two tablespoons, fully soaked, is a typical food amount. Increase slowly and drink enough water, as a sudden jump in fibre can cause bloating.

Can I take sabja seeds in summer every day?

Many families use sabja in summer drinks. As a food in normal amounts, fully soaked, it is a reasonable choice for most people. If you are pregnant, take regular medication or have a digestive condition, check with your doctor first.
