If you need to use it on hair, skin and nails, purchase just one capsule, instead of three separate bottles. The strength of this Nutraharmony biotin review is the width: biotin, collagen, keratin, hyaluronic acid and all 8 B vitamins all in one product and manufactured in the USA in GMP certified facilities. The restriction is patience — the listing’s own study took 90 days and nothing here is speedy. For consistency, give it to the taker who takes it every day.
Best for: Users of biotin who do need collagen, keratin and B vitamins in a single pill.
Don’t use if: If anyone wants to see the effects of hair changes earlier than a 90-day window of study.
Pros:
- Biotin, collagen, keratin and hyaluronic acid in one capsule
- It is an 8 B vitamin complex supplement that includes all B vitamins.
- Stating that it is free of GMOs, free of gluten, and free of harsh fillers.
- Manufactured in USA with a GMP certified facility, third party lab tested
- Ideal for all hair types, including curly, textured and color-treated hair
Cons:
60 capsules in each bottle, which means that you need to restock sooner than you would if you had more capsules.
What Decides This Biotin
When it comes time to make a decision about what to buy for your beauty supplement, there are three parts to consider: What is actually in the capsule, How many pills or capsules will you have to take, and Of course, What evidence is there behind it?
It includes formula for hair, skin and nails.
Beauty multi-complex as listed containing biotin, collagen, keratin, hyaluronic acid, vitamins A and E and natural botanical extracts. This is the actual reason for this as compared to taking a simple biotin pill; the structural proteins and the hydration ingredient are included in the same dose that you take in a vitamin pill each day.
There’s no limiting on the use of this listing, as it says it can be used on all hair, including curly, textured or color-treated hair. For those who already consume collagen powder and biotin separately, this is the perfect product for you. If you only wanted biotin, then you’re paying for ingredients you aren’t asking for.
The evidence is accompanied by a time line
This is the section most purchasers miss out. The listing refers to a 90-day study of 80 women where they reported favorable results in their support of a healthy hair growth cycle and visible improvements in the appearance of the scalp skin, Study #1-0602, 2024. 90 days is the manufacturer’s number, and here it’s the truthful expectations setter.
Hair grows slowly and a hair growth supplement that helps with the hair growth cycle cannot do anything in a fortnight. So, the issue isn’t if it works by the next month, it’s if you will be able to take it by the next month? So if of course you answer no, whatever is in the formula, it is not the product for you.
The complete B-complex is the unassuming distinction
There are many hair supplements that are able to provide you biotin and stop. This one provides you with all 8 essential B vitamins; and it lists them as follows: B1, B2, B3, B5, B6, B7 (as biotin), B9 (as folate), and B12 (as methylcobalamin).
If you have a restricted diet, that’s important too: Folate and B6 are not as well known in the diet, and vegans and vegetarians may need B12 from a supplement. It also means that you’re not getting one ‘star ingredient’ a day – you’re getting a wide range of nutrients daily.
The compromise: When you’re already taking a B-complex, you’d be taking doubles, and so be sure to check the ingredients of your current supplement regimen first.

So, what is found in a biotin review?
The listing includes the number of bottles and the complete formula of products: biotin, collagen, keratin, hyaluronic acid, B-complex, vitamins A and E, botanical extracts. It doesn’t list a serving size or the number of capsules per day, so you can’t use the listing to determine how long one bottle will last.
Before embarking on a lengthy regimen, it’s best to confirm this on the label. Also, the listing does not state whether or not a second bottle is required to finish off the full course. Other than that, it’s all good: no GMOs, no gluten, no unnecessary additives or harsh fillers, made in the USA with globally sourced ingredients in GMP certified facilities, and third party lab tested for purity. These claims are taken seriously when you’re taking the supplement every day. If you plan to use it then it’s worth it.
Frequently Asked Questions
May I use this on color-treated and/or curly hair?
Yes. There is no restriction on who it is for as the formula states it’s good for all hair types, including curly, textured and colour treated. It’s also formulated for both men and women. The nutrients are not selective to one type of hair over another, but promote normal hair growth and help keep hair strong and structured.
What else do I need to purchase in order to get it running?
No, it is not a formula created to go with another product; rather it is a complete beauty multi-complex. It doesn’t specify a serving size, however, so you should consult the label to find out just how far these 60 capsules will last you.
Should you really take a hair supplement like this?
It may be, if you believe the timeline that the listing gives. A 90-day study of 80 women resulted in positive reviews regarding healthy hair growth and visible improvements on the scalp, according to the listing. These types of supplements are regulated as food, not medicines, and the FDA does not review them for effectiveness in the same manner that it reviews medicines; the FDA’s guidance on dietary supplements is worth reading prior to beginning a daily dietary supplement.

If you’ve been considering a supplement, do you think it’s a worthwhile investment?
If you’re looking to start your hair, skin and nail care regimen: absolutely this is a good starting point. The structural ingredients and the complete B-complex are in one habit, and the manufacturing claims — GMP-certified, third-party tested, made in the USA — are the sort you would want in a product you take daily. Just come in with the understanding that the schedule is in months.
If you are someone who already has a B-complex supplement or collagen powder: think carefully. If so, it may be easier to swallow a plain biotin capsule. For all others, it’s a choice between breadth and patience, with patience being the victor.
