Biosilica Capsules give you silicon in the form your body can absorb, for your hair, skin, nails and bones. You take one capsule a day, so each pot of 90 capsules is a 90 day supply.
Silica is the name most supplements use for silicon, a trace element found in your hair, skin, nails and bones. Most silica in food and supplements passes through unused, so the form you take matters.
Biosilica Capsules are most useful for:
Each capsule provides 25mg of silicon as choline stabilised orthosilicic acid. The other ingredients are cellulose, choline and the vegetable capsule shell. Ch-OSA and silicic acid are other names for this form of silicon.
Take one capsule a day with food.
The capsules are suitable for vegans and vegetarians. They are free from gluten, dairy and nuts.
The capsules are made in the UK in a GMP certified cleanroom facility accredited to ISO 9001 and ISO 14001. Every batch is traceable from raw material to finished product. Like every supplement Nutri Tailor stocks, they are practitioner grade and guaranteed additive free.
What form of silica is this?
It is choline stabilised orthosilicic acid, a form of silicon your body can absorb. Standard silica supplements use silicon dioxide, which is largely insoluble.
How much silica should I take a day?
Take one capsule a day, which gives you 25mg of silicon. A pot of 90 capsules lasts three months.
When is the best time to take Biosilica?
You can take it at any time of day, as long as you have it with food.
Can I take it with other supplements?
Yes. Many people take it with biotin and zinc for their hair, skin and nails, or with collagen and vitamin C.
Is it safe to take silica every day?
One capsule gives you 25mg of silicon, which is far below the upper level of 700mg a day set in UK safety guidance.
How long does Biosilica take to work?
Give it 12 weeks of daily use before you judge the results, because hair, skin and nails renew slowly.

Yes. Taking a supplement does not change how you use products on the skin.
Yes, it is vegan. It is free from gluten, dairy and nuts. The full ingredient list and allergen information are on the label image and in the Information and Allergens tab above.
Tablets need binders, fillers and a coating to hold their shape. A capsule is a cellulose shell around the powder, so it carries no binders and breaks down quickly once swallowed.
