Key Benefits of Biotin Supplementation

Biotin plays a vital role in keratin production, the protein that gives your hair and nails their strength. Regular use can lead to thicker, shinier hair and stronger nails that are less prone to breakage. This liquid formula goes further with collagen to support skin elasticity, hyaluronic acid for moisture retention, and vitamin C to boost collagen synthesis. Plus, B vitamins B3, B6 and B9 help with scalp circulation and overall nourishment. The addition of astragalus, traditionally used for vitality, rounds out this comprehensive blend.

What Is Biotin and Why Does It Matter?

Also known as vitamin B7, biotin is a water-soluble nutrient essential for converting food into energy. It's particularly important for maintaining healthy hair, skin, and nails. While deficiency is uncommon, many people find that extra biotin supports their beauty goals. This liquid supplement provides a generous 5,000 mcg per serving (the RDA is just 30 mcg, but higher doses are popular for targeted support). Because it's water-soluble, your body flushes out any excess, making it safe for daily use.

What to Look for in a Biotin Supplement

The best biotin supplements combine quality ingredients with fast delivery. Our liquid formula is designed for sublingual absorption—hold it under your tongue for 30 seconds before swallowing—for up to 98% faster absorption than pills. It's non-GM, Gluten Free, and free from artificial colors and preservatives. The natural berry flavour makes it easy to take every day. We also include apple cider vinegar to aid nutrient absorption. Always check the labelled for purity certifications; this product is third-party tested for potency.

How Much Biotin Should You Take? A Dosage Guide

The recommended daily intake (RDI) for biotin in Australia is 30 mcg for adults. However, many beauty supplements contain higher doses like the 5,000 mcg found in this formula. This level is generally considered safe because biotin is water-soluble and excess is excreted. As with any supplement, it's wise to consult your healthcare professional, especially if you are pregnant, breast-feeding, or on medication. Each 60 mL bottle provides around 30 servings—simply follow the serving size on the labelled.

Possible Side Effects and Interactions

Biotin is well-tolerated by most people. At very high doses, some may experience mild digestive upset or skin reactions. Be aware that biotin can interfere with some lab tests (like thyroid hormone tests), so inform your doctor if you're taking high-dose biotin. Significant drug interactions are rare, but always check with your health professional if you take anticonvulsants or other medications that affect biotin metabolism. This product is not a substitute for medical treatment.

Frequently Asked Questions About Biotin

Does biotin really help hair growth?

Biotin strengthens existing hair and reduces breakage, especially if your levels are low. While it won't make new hair grow faster, you may notice thicker, more resilient locks over time.

Can I take biotin with other supplements?

Absolutely. Biotin pairs well with other B vitamins, collagen, and vitamin C—in fact, this formula already includes them. You might not need extra products.

How long does it take to see results?

Results vary. Nail strength can improve in a few weeks, but hair changes usually take 3 to 6 months of consistent use. For best results, take it daily and shake well before use.

Always read the labelled and follow directions for use.
