## Description

Our supplement is a specially formulated blend of proteins, amino acids, and minerals that can help you achieve your desired beauty goals. It works from the inside out, providing balanced nutrition to promote skin, nail, and hair wellness. The biotin supplement can be taken alone or as an addition to your current skin and hair care regimen to further boost the results you see from this supplement. Let’s talk about Biotin: Biotin, also known as vitamin B7 or H in fitness circles, has been proven to play a significant role in aiding the body to metabolize critical proteins to maintain nail, skin, and hair. The deficiency in this nutrient is actually the reason behind hair, skin, and nails issues. In such cases, a suitable biotin collagen supplement can go a long way in correcting these types of problems. Apart from physical benefits, biotin may help support your cognitive functions. If you are looking for an all-around nutritional powerhouse, then this might just be it. What about collagen? Nothing conveys attractiveness better than glowing skin. Your body's collagen content is a naturally synthesized protein that is responsible for the smooth, even and plump appearance of youthful skin. When the levels of collagen go down unsightly fine lines and wrinkles replace what was once an alluring visage. Nutraharmony biotin collagen capsules are a solution to this problem. Now let’s move to Keratin. Keratin is a building block of the human body. Keratins are tough proteins. They help make up the tissues in the skin, hair, and nails. Our Keratin and Biotin Supplement helps support your overall body. Add these Hair Skin And Nails Vitamins to Cart Today and appreciate your decision in a few weeks. Does it have any known side effects? During the clinical study** no serious adverse events were reported, and the product was generally well tolerated by participants. But, keep in mind that NUTRAHARMONY Biotin capsules formula is a multi-complex blend of active ingredients, so individuals with sensitive digestion may occasionally experience mild gastrointestinal discomfort, such as temporary stomach upset. This is not uncommon with dietary supplements that contain multiple bioactive components. To help minimize the likelihood of discomfort, we recommend taking the product with food and avoiding consumption on an empty stomach. If you have a particularly sensitive stomach, starting with a lower dose and gradually increasing it may also improve tolerance. As with any dietary supplement, individuals who are pregnant, nursing, taking medication, or managing a medical condition should consult a healthcare professional before use. **Study #1-0602, 2024. Does it contain any allergens? Yes. NUTRAHARMONY's Biotin Collagen Keratin supplement contains collagen sourced from fish and also includes coconut extract. Fish is a recognized major food allergen, while coconut is technically classified as a tree nut by the FDA for labeling purposes, allergic reactions to coconut are relatively uncommon compared to other tree nuts. However, individuals with known fish or tree nut allergies should avoid this product or consult their healthcare professional before use. Can this supplement be taken on an empty stomach? Yes, this supplement can be taken on an empty stomach, ideally 15–30 minutes before a meal. However, if you experience any stomach discomfort or sensitivity, we recommend taking it with food instead. This can help improve overall tolerance while maintaining effectiveness. Is this supplement vegan? No, Biotin Collagen & Keratin supplement is not vegan. It contains Collagen sourced from fish, as well as Vitamin D3 derived from lanolin, which is obtained from sheep’s wool. Since both ingredients are animal-derived, the product is not suitable for vegans. Is this gluten free? Yes, Biotin Collagen & Keratin supplement is gluten free. It does not contain gluten or gluten-derived ingredients and is formulated to meet gluten-free standards. Can biotin be taken during pregnancy or while breastfeeding? "Biotin is generally considered safe when used as directed and taken within the recommended daily dosage. However, if you are pregnant, planning to become pregnant, or breastfeeding, we strongly recommend consulting your healthcare provider before starting any dietary supplement to ensure it is appropriate for your individual needs." Can it be taken daily? Yes. Biotin Collagen & Keratin capsules formula is designed for safe, everyday use when taken as directed. How long & how often can I take this supplement? What is the recommended duration of use? A minimum 90-day course is recommended for optimal results. Depending on your goals, the supplement can be taken continuously or repeated after a short break. For personalized guidance, consult your healthcare provider. Is it safe to combine this biotin with other supplements? Yes. NUTRAHARMONY hair vitamins formula is designed to complement other wellness supplements and is generally safe to combine with commonly used products such as B-Complex, Vitamin D3+K2, Collagen Peptides, Magnesium, Glucosamine, Mullein, Cinnamon, Beet Root, and Lymphatic Support formulas. As with any supplement regimen, if you are taking prescription medications, managing a medical condition, pregnant, or breastfeeding, it is recommended to consult your healthcare provider before combining multiple supplements.

Review: Effective Biotin Supplement for Hair Growth, Strong Nails & Healthy Skin” - ⭐️⭐️⭐️⭐️⭐️ Amazing Results for Hair, Skin & Nails! I’ve been taking Nutra Harmony Biotin with Collagen & Keratin (25,000 mcg) for a few weeks now, and I’m honestly impressed with the results. The first thing I noticed was a significant reduction in hair shedding, especially when brushing or showering. My hair feels stronger and healthier overall. My nails are growing faster and feel much harder, and I’ve also noticed my skin looks more hydrated and smooth. I like that this formula includes collagen, keratin, and B vitamins, which makes it a complete beauty supplement. The capsules are easy to swallow, and I haven’t experienced any side effects. I also appreciate that it’s non-GMO, gluten-free, and made in the USA. One bottle lasts a good amount of time, so it’s a great value for the price. If you’re struggling with hair thinning or weak nails, I highly recommend giving this biotin a try. I will definitely be repurchasing!

This is a reliably good product. I like the ingredients & improvements in hair growth. The capsules are easy to swallow.

### ⭐⭐⭐⭐⭐ This supplement out preforms all others.
*by A***R on February 14, 2026*

Wow used this product n after 2 months I am seeing a big improvement in my hair n nails. N I am getting thicker n shinier hair. My hair dresser even commented on my hair condition n could see new hair follicle appearing. I have hair extensions n the increase in volume of hair is helping keep my extensions in place. Will never quit using these. Have tried many hair supplements without seeing any change. Well worth the money. I happened to catch a sale n have a supply to last me a year.
