I've been using this brand and type of microlingual tablets for a long time now. My nails are generally healthy and strong, so I guess that it's working. The under-the-tongue method of taking these tablets is very simple. They're small and dissolve quickly with a very minor taste that's not unpleasant. Review: This was the 2nd order for me and I sent my daughter an order - Had used before. My nails and hair had improved. Easy to take . Under the tongue and that’s it. ## Features - Daily Biotin Supplement: Our Biotin supplement supports healthy blood, cell growth, metabolism of fats and amino acids, and the production of fatty acids - Supports Healthy Hair & Nails: This Biotin supplement is formulated to support healthy nails and skin and aids healthy hair growth - Fast-Acting Dissolvable Supplement: Instant Dissolve MicroLingual tablets provide quick support for a healthy scalp without the bulk of a large tablet - Precise Biotin Dosage: Each Biotin supplement tablet is formulated with 5 mg of biotin to support healthy hair and nails - About Us: Superior Source has been formulating sublingual vitamins since 1998 in our family-owned manufacturing facility ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003VRBLMA | | Age Range Description | Adult | | Allergen Information | Non-GMO | | Best Sellers Rank | #192,742 in Health & Household ( See Top 100 in Health & Household ) #440 in Vitamin B7 (Biotin) Supplements #5,178 in Sales & Deals | | Brand | Superior Source | | Brand Name | Superior Source | | Color | White | | Customer Reviews | 4.7 out of 5 stars 536 Reviews | | Diet Type | Vegetarian | | Dosage Form | Tablet | | Dose Release Method | Sublingual | | Flavor | Unflavored | | Global Trade Identification Number | 00076635903108 | | Item Dimensions | 1.44 x 1.44 x 2.38 inches | | Item Form | Tablet | | Manufacturer | Continental Vitamin Company, Inc | | Manufacturer Part Number | 90310 | | Model Name | Superior Source Biotin Instant Dissolve MicroLingual Tablets | | Model Number | 90310 | | Number of Items | 1 | | Primary Supplement Type | Lactose, Biotin and Gum Arabic | | Product Benefits | Supports Healthy Energy & Growth | | Special Ingredients | Biotin | | Specific Uses For Product | Supports Healthy Energy & Growth | | Supplement Formulation | Individual Supplement | | UPC | 076635903108 784922212030 | | Unit Count | 100 Count | ## Product Details - **Brand:** Superior Source - **Flavor:** Unflavored - **Item Form:** Tablet - **Primary Supplement Type:** Lactose, Biotin and Gum Arabic - **Product Benefits:** Supports Healthy Energy & Growth ## Images ![Superior Source Biotin 5000 mcg Sublingual Dissolving Tablets - Daily Supplement Supports Hair Health & Growth, Healthy Nails & Skin - 100 Count - Image 1](https://m.media-amazon.com/images/I/71vFpsNlTcL.jpg) ![Superior Source Biotin 5000 mcg Sublingual Dissolving Tablets - Daily Supplement Supports Hair Health & Growth, Healthy Nails & Skin - 100 Count - Image 2](https://m.media-amazon.com/images/I/71bUzllNSzL.jpg) ![Superior Source Biotin 5000 mcg Sublingual Dissolving Tablets - Daily Supplement Supports Hair Health & Growth, Healthy Nails & Skin - 100 Count - Image 3](https://m.media-amazon.com/images/I/715Szi+DOSL.jpg) ![Superior Source Biotin 5000 mcg Sublingual Dissolving Tablets - Daily Supplement Supports Hair Health & Growth, Healthy Nails & Skin - 100 Count - Image 4](https://m.media-amazon.com/images/I/61P2zgSy9+L.jpg) ![Superior Source Biotin 5000 mcg Sublingual Dissolving Tablets - Daily Supplement Supports Hair Health & Growth, Healthy Nails & Skin - 100 Count - Image 5](https://m.media-amazon.com/images/I/71lwZQAB+LL.jpg) ## Questions & Answers **Q: Is this product Gluten free?** A: Sorry, I don't know.

I've read Biotin may help with sleep. I like this brand a lot. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sublingual Biotin *by S***A on October 30, 2024* Years ago when I was having some issues with nail growth following other medical treatment, a doctor recommended getting sublingual Biotin and B12. I've been using this brand and type of microlingual tablets for a long time now. My nails are generally healthy and strong, so I guess that it's working.

My nails and hair had improved. Easy to take . Under the tongue and that’s it. ### ⭐⭐⭐⭐⭐ It works! *by P***Y on July 13, 2023* Superior source products are superior since the company does not use flow agents or fillers. That is very important. Flow agents and fillers can affect health negatively since they can affect nerve endings and fibroblasts and fibroclasts. The company offers a range of products as well as grade of products. For example, the company offers the high quality methylcobalamin as well as the cheap grade cynocobalamin. The lower quality grade costs less. My point is that it is important to know that it is way better to pay a few dollars more and get the higher quality ingredients. I checked the Biotin. All the ingredients listed are made from the high grade ingredients. You will notice a difference in your health when you use Superior Source products. I highly recommend this Biotin from Superior Source.A+++++ ## Frequently Bought Together - Superior Source Biotin 5000 mcg - Daily Supplement Supports Hair Health & Growth - Natural Biotin Supplement Aids Healthy Nails & Skin - 100 Sublingual Dissolving Tablets - Superior Source Vitamin D3 5000 IU - Offers Immune System, Brain & Nervous System Support - Aids Calcium Absorption for Teeth & Bone Health - Bariatric Friendly - 100 Sublingual Dissolving Tablets - Superior Source No Shot Methylcobalamin B-12 1,000 mcg - Vitamin B-12 to Support Energy Production, Brain Health & Overall Wellness - Sublingual Tablets for Rapid Absorption - 60 Dissolving Tablets --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/4922476-superior-source-biotin-5000-mcg-sublingual-dissolving-tablets-daily-supplement](https://www.desertcart.ec/products/4922476-superior-source-biotin-5000-mcg-sublingual-dissolving-tablets-daily-supplement) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-07-18*
