What customers say
Customers generally appreciate the product for its good taste, ease of use, and portability. Many users highlight its effectiveness in improving hair, skin, and nails due to the combination of biotin and collagen. The product is praised for its high-quality ingredients and reliable brand reputation. Some customers report noticeable improvements after consistent use over a month, while others are still evaluating results. However, opinions on taste vary; some find it delicious with a fruity aroma, while others dislike it or find it too sweet. A few users noted undissolved impurities in the drops. Despite mixed reviews on flavor, the overall quality and convenience make it a popular choice among users seeking beauty benefits from supplements.

Helping with Hair Loss
Verified purchase
My hair has been falling out more than I would like due to a hormonal imbalance. I am on my second bottle of this product and I have noticed a reduction in hair loss and my hair seems thicker. It also seems a bit stronger, less prone to breakage so I will continue using this product while getting my hormones balanced.

Great taste
Verified purchase
As always, Trace Minerals is top quality. Not only does it have biotin and collagen but also trace minerals as well. I love that I get all three in one package. I was expecting the taste to be the same as the other trace mineral supplements but was pleasantly surprised by this, as it tastes so much better making it easier to take.

Good product, but didn't like the taste
Verified purchase
I like the product ingredients list, this is the reason I ordered it. The package is quite handy and good quality, the size is just perfect for such a product. I've been using it for about a month. Everything is good about this product, except the taste, honestly its nightmare, I didn't like it at all. Unfortunately there are no other taste options for this product, so for me it was a one time purchase. You might try it, maybe the taste was a problem only for me.

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

Great
Verified purchase
Good quality ingredients and composition. It tastes great but the dropper is a little inefficient. But it is convenient since it’s in liquid form and taste good. Can either mix it with water rot have it as it is.

Ingredients are of high quality with dosage size being ideal to flavour 500ml of water. The skin and hair have a better structure now. The benefits of collagen shows improvement in nails, hair and skin quite quickly.
