If you’re thinking about silica supplements, you’re not alone. Who wouldn’t be drawn in by glowing skin claims and hair-growth promises? 

But here’s what we know: silica is a vital mineral your body uses daily. Its beauty benefits? Still up for debate. 

The good news is – you don’t have to navigate the hype alone. We’ve cut through the noise and rounded up H&B customer-loved silica picks, plus some with collagen for extra support

What is silica?

Silica is a natural compound and mineral that can be found all around the world – mostly in rocks, clays and sands.

Ever opened a new pair of shoes, unboxed electronics, or bought a bottle of pills? Then you’ve definitely met silica gel packets – yep, they’re those tiny "do not eat" sachets used to keep things dry. 

However, silica supplements are quite different. They come from silica’s water-soluble form, which is found in certain plants, including the herb horsetail.2

What are the potential benefits of silica?

Silica is an essential trace element found in our bodies. That means we only need a tiny amount, but it’s important nonetheless. 

While scientists have been interested in silica for a while (since the 70s, in fact) and potential benefits are promising, more research is needed to fully understand silica's role in human health.3-5 

Silica naturally occurs in healthy hair, which has led many to wonder – could it be the secret to stronger, shinier strands? While science hasn’t yet proven a direct link between silica supplements and luscious locks, some people still take them in hopes of boosting hair, skin, and nail health. Think of it as a ‘might help, can’t hurt’ approach – more of a supportive player than a miracle worker. 

Always consult with a healthcare professional before adding new supplements to your regimen.

Our top silica supplements – as chosen by you

Although you can get silica through some types of food (like whole grains, fruit and veg), some people may choose to use silica supplements to support the role of silica in their body.11,12 

From tablets to gummies and more, let’s look at the range of silica supplements on the market.
Starpowa Vegan Collagen Support 60 Gummies

Vegan

Starpowa

51.99

€0.87/1 Chewable

Glow-getter gummies that do the hard work for you

These tasty, cloudy lemonade-flavoured gummies are clinically studied to support your body’s natural collagen production. They contain high-quality hyaluronic acid, branched-chain amino acids and bamboo which is standardised to contain natural silica, which may support skin moisture and a natural glow.13 

They also contain vitamin C, which contributes to normal collagen formation for the normal function of the skin and is linked to collagen production. These gummies are vegan-friendly and naturally flavoured and sweetened. Plus, they contain less than 0.1g of sugar per gummy. Just chew two gummies a day.

For plant powered goodness

Our Silica Complex supplements offer a combination of calcium, magnesium, zinc, betaine hydrochloride, boron and horsetail. Zinc and calcium contribute to the maintenance of normal bones, while zinc contributes to the maintenance of hair, nails and skin. Calcium and magnesium also contribute to normal muscle function. 

They’re suitable for vegans and also don’t contain sugar, soya or gluten. Take one caplet daily, preferably with food.

Silica alternatives: what’s out there?

Silica supplements are one way to support your overall wellbeing, but they’re not the only option with skin in the game.4 Collagen, your body’s key structural protein that your body needs to support its normal functions, works especially well with silica, helping maintain skin elasticity and strong hair and nails.14,15 

Let’s look at some of your favourite collagen products…

It also contains added vitamin C, which contributes to normal collagen formation for the normal function of skin. Then biotin and selenium, which contribute to the maintenance of normal hair. And finally, selenium, which contributes to the maintenance of normal nails. 

Take three tablets with a glass of water daily to start seeing the benefits.
 

The final say

Silica may not make headlines like other supplements, but this humble mineral plays a quiet yet important role in our wellbeing. While research is still uncovering its full potential, many of our customers have made it part of their daily health routines. 

So next time you spot one of those "do not eat" silica gel sachets, you might see them in a new light. (Though obviously, they're no substitute for proper supplements – stick to the ones meant for humans!) 

Silica supplements are considered safe for most people. However, if you’re considering taking a silica supplement, it’s important to check with your doctor to ensure it’s safe and doesn’t interfere with any medication you’re on.
