Main highlights

Silicone from bamboo sprouts: young bamboo shoots (Bambusa vulgaris) are naturally particularly rich in silicon and are ideal as a dietary supplement. We rely on a high-quality bamboo shoot extract with an exceptionally high content of 75% natural silica - for an effective supply of valuable silicon to the body.
Optimal supply for 4 months: the silicone capsules come in a practical storage pack with 240 pieces. If taken daily (2x), one can is enough for a full 4 months - ideal for long-term, uncomplicated use.
Optimal high dose: each capsule contains 357 mg bamboo shoot extract with 268 mg natural silica - of which 125 mg elemental silicon. We recommend taking 2 capsules daily with sufficient liquid to provide a total of 250 mg of silicon to the body.
No undesirable additives: our capsules do without unnecessary additives - the ingredient list is correspondingly short: high-quality bamboo shoot extract as a natural silicon source and a vegetable capsule shell made of hydroxypropylmethylcellulose - that's it.
Laboratory tested and made in Germany: our silicon capsules are made exclusively in Germany and contain no ingredients of animal origin. As part of our quality assurance, we have the silicon capsules regularly analysed by an independent food laboratory - analysis certificate see 5. Image in the picture gallery.
