Interested in taking silica supplements but not sure which to buy?

Whether you’re looking for a vegan silica tablet or a collagen blend, we’ve listed eleven of the best silica products for you to try.

In this article, you’ll find out:

  • What silica supplements do
  • If it’s safe to take silica supplements
  • What does silica do in the body
  • Is silica better than biotin
  • 11 of the best silica products

What do silica supplements do?

Silica supplements are an essential part of all bone health and help to increase skin radiance.

Our nutrition expert Alex Glover highlights exactly what silica is:

“Silica is an essential component of bone, which is mainly involved in bone remineralisation. This process draws minerals into the bone matrix when developing new bone.”

Is it safe to take silica supplements?

Yes, silica supplements are safe for most people to take. However, it is not recommended for children, pregnant women or people with kidney disease.1

Is silica better than biotin?

Both silica and biotin have a range of health benefits, but the main feature that sets them apart is the side effects.

Biotin seems to have a stronger reaction in some people when taken in larger doses, causing symptoms like stomach upset, headaches and acne breakouts.2

  • Suitable for pescatarians

Customer reviews: 4.3/5 stars

Mel_R - 5/5 stars
“I've been taking these for about 4 months now - skin looks better, feel like there are less crevices for makeup to sit in, nails look better & hairdresser just commented on how great the condition of my hair was, which is not the usual reaction I get from her!”

Kimpv – 5/5 stars
“Really pleased with these. My skin on my chest started to smooth after a week, my mum is really impressed too. Skin on face feels so much better and not dry. Highly recommend”

  1. Starpowa Vegan Collagen Support 60 Gummies

Looking for a vegan supplement packed with ingredients to support collagen production?

Look no further than the Starpowa Vegan Collagen Support Gummies – ideal if you don’t get along with swallowing tablets.

Key features

  • Suitable for vegans and vegetarians
  • Cloudy lemonade flavour
  • Contains bamboo silica
  • Less than 0.2g sugar per gummy

Customer reviews: 4.8/5 stars

Ciara Jenner – 5/5 stars
“I have been taking these for about 2 weeks now; I had wanted to up my collagen intake for some time but a lot of collagen supplements are beef or fish-based therefore not suitable for veggies or vegans. I have noticed a huge difference in my nails so far, they have taken a battering this last year or so with all the extra glove wearing, additional hand washing and alcohol rub (I work for the NHS, my hands have been battered for years...) and I had noticed the my nails would often break underneath the white part which would be painful. Since taking these, my nails haven't broken AT ALL which is unheard of. I don't think I've taken them for long enough to notice a real difference in my skin and hair yet but I've noticed more baby hairs growing on my hairline. They taste really good and the gummies are nice and soft. Highly recommended and much better than the biotin supplements I used to take which would flare up my acne.”

Wendy – 5/5 stars
“Love the taste and texture. Haven’t missed a day of taking them yet. Will continue to order.”

Anonymous – 5/5 stars
“This really works, I have noticed a big difference after only three weeks. My hair is shiny and smooth and my skin is glowing. Highly recommended.”

Cuquix – 5/5 stars
“This is a great way to up your intake of collagen. Since our bodies need this as we our production levels slow down over a certain age. This is great as it doesn’t taste of anything so it can be added to any hot or cold drink for an extra boost. I’ve tried this in juices, smoothies, yoghurts and just water too. If you’re looking for something to discreetly add to your beverages then this is great. Plus it’s in the larger size so you get more for your money as you use up to 2 scoops a day.”

“Good tasting collagen drink that's easy to transport and drink straight from the sachet. The texture isn't gloopy which is what I was worried about (the packaging reminds me of terrible energy gels!) I like the flavour, the potency (contains more hydrolysed collagen than other products), individually proportioned servings so there is no messing about with powders and mixing into water/other liquid. Most importantly, it seems to work! After just 28 days (2 boxes) my skin already feels firmer and looks brighter.”

mommajen17 – 5/5 stars
“Tried other collagen products and I thought I give this one a try as the skin Perfectil had sold out. I am 49yrs and eat well & exercise however I had quite frizzy, dry hair. This had more marine collagen (7000mg) than the skin version so that was better. After half a box through, I noticed the almost immediate effect (the taste was getting used to but I usually drink some water afterwards to get rid of the aftertaste!). After half a box my hair was shiny, smooth & even darker (my hair is black, brown & I have grey hairs). I bought 4 boxes in the Black Friday sale and glad I did! I'll wait for the Xmas sales now to buy more!”

HJM75 – 5/5 stars
“I took this after noticing my hair was getting a bit lifeless and thinner towards the end of following the Cambridge Diet. It immediately put some oomph back into my hair. I have subsequently bought 2 more boxes, and aim to take a box a month. Definitely worth a try.”
