Trace Ionic Biotin + Collagen (75,000 mcg, strawberry-mango) is not just biotin, but a complete liquid complex for supporting hair, skin and nails. Contains biotin, collagen and ionic trace elements ConcenTrace®. Convenient form - easy to take, pleasant taste, natural. After a few weeks, you will notice that your hair becomes livelier, shinier, your nails are stronger, and your skin is more moisturized. It is worth considering that the dose of biotin is high, so you should not exceed it. It works best in combination with good sleep, nutrition and water balance. A good option for those who want to support beauty from the inside without pills.

Wonderful
Verified Purchase
I've bought this twice. The quality is excellent, it works, the ingredients are great, the size is small, it's for hair, and it really helped my skin after giving birth. The packaging is good, and it's beneficial. My nails, skin, and hair have all improved. It's a high-dose collagen product. I like the taste, and it improves my dermatitis.

Amazing
Verified Purchase
Tastes great ! I have it every morning with my chia seeds yoghurt or sometimes to my chia water or even to my latte for some fruity flavour. I'd appreciate if they'd mention what kind of collagen/gelatin they use tho. Is it vegan/halal or pork/animal based

It's easy
Verified Purchase
It's small and easy to carry around. I like it even more because it contains biotin. I take it with silica, and it seems to taste good considering how easy it is to take. I hope it improves as it is said to be good for hair and skin.

I recently tried Trace, Ionic Biotin + Collagen in Strawberry and Mango flavors, and I want to share my experience using it. Firstly, the 59 ml (2 fl oz) packaging is very convenient to use. The bottle is easy to hold, and the pump dispenser allows you to accurately measure the amount you need. I appreciate that the product contains 75,000 mcg of biotin and collagen, making it an excellent choice for supporting healthy hair, skin, and nails. The strawberry and mango flavor is simply amazing! I was pleasantly surprised, as many supplements have an unpleasant aftertaste. This product is easy to take, and I enjoy adding it to my morning routine. After a few weeks of use, I noticed significant improvements. My hair has become stronger and shinier, and my skin looks more hydrated and healthy. I also noticed that my nails have become less brittle. This is a truly remarkable effect, especially considering I have always been looking for an effective product to improve the condition of my hair and skin. Another plus is that the product contains only natural ingredients, without artificial additives. This is important to me, as I try to choose only high-quality and safe supplements. The only thing to keep in mind is the need to follow the recommended dosage. I always read the instructions carefully and consult with a doctor before starting any supplements. Overall, I'm very pleased with Trace, Ionic Biotin + Collagen and can recommend it to anyone who wants to improve the condition of their hair, skin, and nails. It's an excellent product with a pleasant taste and noticeable results!
