Biotin in Bangladesh costs ৳990 to ৳3,650 a bottle at Orpa today, across 14 in-stock biotin supplements. Per capsule that runs from about ৳10.1 to ৳33.0, and the cheapest bottle on the shelf is not the cheapest to take — a ৳990 bottle of 30 capsules costs more per day than a ৳3,650 bottle of 360.
The more useful answer is that the dose on the front of the bottle is the least important thing about it. Below is what the labels mean, what the evidence actually supports, one safety point that almost no product page mentions, and the price of every strength Orpa stocks.
10 mg and 10,000 mcg are the same thing
This is the single most common confusion, and it is worth settling before you compare prices. Biotin is sold in micrograms (mcg) and sometimes in milligrams (mg). One milligram is 1,000 micrograms, so:
| On the label | Same as | Times the adult daily target |
|---|---|---|
| 1,000 mcg | 1 mg | about 33x |
| 5,000 mcg | 5 mg | about 167x |
| 10,000 mcg | 10 mg | about 333x |
Swipe the table sideways to see every column.
So a bottle marked “Biotin 10 mg” and a bottle marked “Biotin 10,000 mcg” are the same strength. If you searched for one and found the other, you have not found a different product.
How much biotin you actually need
The adult adequate intake is 30 mcg a day, and adults in Western countries typically already get roughly 35 to 70 mcg a day from ordinary food, according to the US National Institutes of Health Office of Dietary Supplements. Biotin is in eggs, liver, fish, nuts, seeds and sweet potato.
That means every strength in the table above is many times what the body is known to need, and that true biotin deficiency is, in the NIH’s words, very rare. Deficiency does cause thinning hair and loss of body hair — that part is real and well established — but it is the deficiency that causes it, not a shortfall against 5,000 mcg.
What biotin does and does not do for hair
Honestly: if you are not deficient, the evidence that biotin improves hair is weak. The NIH states plainly that there is little scientific evidence to support the claim that biotin supplements improve hair, skin or nails in people who are not deficient. The studies that do show a benefit are mostly case reports in people with a diagnosed deficiency or a rare inherited hair disorder, and the NIH describes that work as too preliminary to recommend biotin for these uses.
Biotin also has no established toxicity — it is water-soluble and excess is excreted — so the risk of a high dose is not poisoning. The real cost of a 10,000 mcg habit is money, and the lab-test problem in the next section.
If the thing you are actually trying to fix is hair loss with a pattern to it — a receding hairline, thinning at the crown — the treatments with real evidence behind them are a different category entirely. Our minoxidil price guide covers those, and our hair oil guide covers what an oil can and cannot do.
Before you buy: biotin breaks some blood tests
This matters more than anything else on this page, and you will not find it on most product listings.
High-dose biotin interferes with a wide range of laboratory immunoassays, because many of those tests use biotin in their own chemistry. The US Food and Drug Administration has warned specifically that biotin can cause falsely low troponin results — troponin being the blood test used to diagnose a heart attack. The FDA has continued to receive reports of biotin interference with these tests and publishes a list of troponin devices that are still affected. See the FDA’s page on biotin interference with troponin lab tests.
Thyroid and other hormone tests can also be thrown off, which is the interference the NIH highlights. The practical advice is simple and is worth following:
- Tell the doctor and the lab that you take biotin before any blood test, and say the dose. A 10,000 mcg habit is the relevant kind.
- If a result does not match how you feel or what the doctor expects, mention biotin as a possible cause rather than assuming the number is right.
- Ask the doctor how long to stop before a test. Do not guess, and do not stop a prescribed medicine on your own.
None of this makes biotin dangerous to take. It makes it something your doctor needs to know you are taking.
Biotin price in Bangladesh: every strength in stock
Prices are Orpa’s current selling prices in Bangladeshi Taka, read from the live catalogue on 10 November 2026. The “per capsule” column is simply the bottle price divided by the number of capsules, tablets or softgels in it, which is the only fair way to compare a 30-count bottle with a 360-count one.
1,000 mcg — the closest thing to a sensible daily dose
| Product | Count | Price | Per capsule |
|---|---|---|---|
| Nature’s Bounty Biotin 1000 mcg | 100 tablets | ৳1,140 | ৳11.4 |
| NOW Biotin 1000 mcg | 100 veg capsules | ৳1,440 | ৳14.4 |

5,000 mcg — the most commonly bought strength
| Product | Count | Price | Per capsule |
|---|---|---|---|
| Nature’s Bounty Biotin 5000 mcg | 150 softgels | ৳1,550 | ৳10.3 |
| NOW Foods Biotin 5000 mcg | 120 capsules | ৳1,990 | ৳16.6 |

Swipe the table sideways to see every column.
The Swanson bottle is the cheapest biotin in the shop and the dearest way to take it — 30 capsules at ৳33.0 each. It is the right buy for exactly one thing: finding out whether you will actually remember to take it daily before committing to a bigger bottle.
10,000 mcg — also sold as “10 mg”
| Product | Count | Price | Per capsule |
|---|---|---|---|
| NatureBell Biotin 10000 mcg + Hyaluronic Acid | 360 softgels | ৳3,650 | ৳10.1 |
| NeoCell Biotin 10000 mcg Fast Dissolve | 180 tablets | ৳2,190 | ৳12.2 |

| Sports Research Biotin Max Strength 10,000 mcg | 120 veggie softgels | ৳3,440 | ৳28.7 |
Swipe the table sideways to see every column.
Two of these are not plain biotin: the NatureBell bottle adds hyaluronic acid and coconut oil, and the Carlyle one adds keratin. If you want biotin and nothing else, the NeoCell and NOW bottles are the straightforward picks in this strength.
What to actually buy
- Lowest running cost: NatureBell 10,000 mcg at ৳10.1 a softgel, or Nature’s Bounty 5000 mcg at ৳10.3. Within ৳0.2 of each other, so pick on strength rather than price.
- Closest to what the body needs: Nature’s Bounty 1000 mcg at ৳11.4. Still about 33 times the daily target.
- Cheapest way to try it: Swanson 5000 mcg, 30 capsules, ৳990.
- Vegetarian capsules: the NOW and Sports Research veg capsule lines. Softgels are usually gelatin.

Frequently asked questions
What is the price of biotin 5000 mcg in Bangladesh?
At Orpa, ৳990 to ৳2,390 depending on the bottle size, as of 10 November 2026. The cheapest per capsule at this strength is Nature’s Bounty Biotin 5000 mcg at ৳10.3 a softgel (150 softgels for ৳1,550); the ৳990 Swanson bottle holds only 30 capsules, which works out at ৳33.0 each.
Is biotin the same as vitamin B7?
Yes. Biotin, vitamin B7 and vitamin H are three names for the same vitamin. A label using any of them is describing the same thing.
Is 10,000 mcg of biotin too much?
It is far more than the body is known to need — about 333 times the adult adequate intake — but biotin has no established toxic dose and excess is passed in urine. The practical issue with a high dose is not harm, it is that it can skew blood tests, including the troponin test used to diagnose a heart attack. Tell your doctor and the lab that you take it.
Does biotin regrow hair?
If your hair loss is caused by biotin deficiency, correcting the deficiency helps. Deficiency is very rare, and in people who are not deficient the NIH says there is little scientific evidence that biotin improves hair. It is not a treatment for pattern hair loss.
How long before biotin shows any effect?
Hair grows roughly a centimetre a month, so any change in the hair itself takes months to become visible rather than weeks — and that is only if a deficiency was the problem in the first place. Judge it over three to six months, not three weeks.
Should I take 1,000, 5,000 or 10,000 mcg?
There is no evidence that a bigger number works better in people who are not deficient, so the lowest strength is the most defensible and the highest strength mainly costs more and interferes with lab tests more. Ask a doctor if you are treating a diagnosed problem.
Can I take biotin while pregnant or on medication?
Ask your doctor rather than a product page. This is general information, not medical advice, and biotin’s interference with blood tests is a reason for your doctor to know about it.
Are these imported products original?
Yes. Orpa imports sealed stock and sells it with cash on delivery across Bangladesh. Every product linked above is in stock at the price shown as this page is written.
