What customers say
Customers have reported significant improvements in the strength and growth of their hair and nails after using BioSil, with many noting stronger, longer nails and healthier, thicker hair. Some users also observed smoother skin and reduced fine lines. The product is praised for its quality ingredients, particularly the specific type of silica that aids in detoxifying aluminum from the body. A few customers mentioned improved joint health and increased energy levels. While some found the taste unpleasant, mixing it with juice made it more tolerable. There were mixed reviews on its effectiveness for skin improvement, with some seeing noticeable changes while others did not. Overall, BioSil is well-regarded for its positive impact on hair, nails, and skin.

Great
Verified purchase
I ordered it for my hair. Going to take it for 6 months. So far I’m in my second month I’ve noticed that my nails got stronger regarding my hair can’t say anything. I was loosing quite a lot of hair and now it got slightly better. But as I said I’m aiming to take biosil for a longer period

Great with Collagen Peptides
Verified purchase
Quality supplement with mineral-rich ingredient composition that enhances collagen absorption. The 30ml size is convenient for daily frequency use alongside collagen peptides. Benefits include addressing deficiency symptoms like joint discomfort and skin dullness. Good packaging preserves potency. Taste is mildly citrus and pleasant. Essential complement to my collagen routine.
Safe and sound

For kids who don’t eat meat
Verified purchase
It has some taste I think not every child would drink it with water. It’s better to add them into juice for better taste. It’s a great product we have been taking it for a month so it’s early to say anything.

You need to get this supplement
Verified purchase
I bought this to help with my hair, nails and skin. Within a week of daily use, I could see a difference. My skin looked smoother and softer and my hair and nails have been growing like weed. The quality of the supplement is great and the packaging is also good. You will definitely benefit greatly from adding it to a well aging routine.

I love this product so much. This is not my first time ordering. I always keep on ordering this product over and over again. The size is really good it last you for a good time. The ingredients list is very simple and easy to promote collagen and the package is very good as well.

My experience so far has been fairly neutral. The quality of the product seems fine, and the bottle size is convenient. It’s different from traditional collagen since it doesn’t contain any added minerals or typical collagen ingredients, which might appeal to some people. As for the benefit, it’s a bit early for me to say how noticeable the effects are, but it fits easily into my routine and doesn’t have much taste, which helps.

My go-to collagen “generator”. I’ve taken this for many years now and the fact I don’t feel my joints aching despite being in my middle age means it works. Taste is consistently terrible though 😅 like I’m drinking fish 😅. I find blending it into my supergreens powder helps to hide the taste.
