Silicon is the second most abundant element in the Earth’s crust, but its presence in the human body is very low, despite being involved in essential biological processes, particularly the synthesis of collagen, elastin and glycosaminoglycans — the three families of molecules that form the framework of connective tissue, giving structure and resilience to bones, cartilage, tendons, skin and blood vessels. “Orthogenic” refers to orthosilicic acid (Si(OH)4), the form of silicon most easily absorbed by the human body. In nature, silicon exists in many forms, most poorly bioavailable; orthosilicic acid is the only form naturally soluble in water and directly assimilable by the digestive tract. This supplement uses that form, stabilised with choline to maintain its solubility and bioavailability over time.

The technical challenge with organic silicon is its natural tendency to polymerise — forming insoluble silica chains that the body can no longer absorb. To prevent this, choline is used as a stabilising agent. Choline is itself an essential nutrient (a precursor of acetylcholine and a component of cell membranes), giving this formula a dual nutritional benefit. Each capsule provides 50mg of orthosilicic acid silicon, i.e. 12.5mg of elemental silicon, in convenient vegetable capsules (hydroxypropylmethylcellulose) offering precise dosing, easy transport and no taste.

Silicon plays a role in bone mineralisation by supporting the deposit of calcium and phosphorus in the bone matrix, and contributes to the synthesis of type I collagen, which forms the organic scaffold of bone onto which minerals attach. Adequate silicon intake therefore complements calcium and vitamin D for maintaining strong bones. At the joint level, silicon is involved in producing glycosaminoglycans, essential cartilage components, and helps maintain cartilage hydration and suppleness — particularly relevant for active people, athletes, or anyone wishing to preserve joint comfort. Silicon is also involved in tendon and ligament health, supporting collagen and elastin synthesis in these tissues.

Silicon is a valuable ally for skin beauty. By stimulating collagen and elastin production, it helps maintain skin firmness, elasticity and hydration, which is why many people include it in an anti-ageing or general skincare routine. For hair, silicon is a structural component of keratin — intake of organic silicon can contribute to hair strength and shine, and it’s often paired with biotin, zinc and B vitamins in hair-support routines. Nails also benefit from silicon intake, which supports their hardness and resistance; brittle, soft or ridged nails can be a sign of silicon shortfall among other possible deficiencies.

Recommended dose is 1 to 2 capsules a day, taken with a meal and a glass of water. For joint comfort or bone health, 2 capsules a day (100mg orthosilicic acid silicon, 25mg elemental silicon) is the optimal dose; for a beauty-focused goal (skin, hair, nails), 1 capsule a day is often sufficient as a maintenance dose. A 2-3 month course is generally recommended, renewable after a break of a few weeks, as collagen, elastin and glycosaminoglycan renewal is a slow process, so consistency is essential. Organic silicon pairs well with calcium, vitamin D, magnesium and vitamin C (needed for collagen synthesis); for joint concerns, combining with glucosamine, chondroitin or turmeric can also be considered.

Do not exceed the recommended daily dose. Food supplement. Not a substitute for a varied, balanced diet and a healthy lifestyle. Keep out of reach of children.

What is the difference between organic and mineral silicon?

Mineral silicon (silica, quartz) is abundant in nature but virtually unassimilable by the human body. Organic silicon refers to forms of silicon bound to organic molecules or presented as orthosilicic acid, which are bioavailable and can be absorbed through the digestive tract. This supplement uses choline-stabilised orthosilicic acid, the most advanced form in terms of bioavailability.

Can organic silicon be taken alongside calcium?

Yes, and it’s even recommended. Silicon and calcium work in synergy for bone health: silicon supports the deposit of calcium in the bone matrix and stimulates the synthesis of type I collagen that forms bone’s organic scaffold. A silicon + calcium + vitamin D combination is often recommended for comprehensive bone support.
