01 · Anatomy of microtrauma
Intense exercise leads to adaptations and physiological micro-injuries that are repaired during recovery.
Every session breaks myofibrils and tendon collagen fibers. Your body repairs them — if it has the raw materials. Organic silicon is one of the most critical structural cofactors for tendons, ligaments, and connective tissue. And after 23 years of continuous use (Geusens et al, 2017 · Boqué et al, 2021 · Petersen Vitello, 2018), it remains permitted in competition.
From micro-tear to strengthened fiber
Swelling, warmth, micro-bleeding. The body clears the damage and prepares the area.
Fibroblasts arrive and produce new collagen. Silicon has been studied in processes related to connective tissue.
The new collagen aligns with mechanical forces. The fiber reorganizes.
New tissue stronger than before — if the raw materials were available.
The difference between recovering and overtraining isn't how much you train — it's how much structural material you have available when it's time to repair.
Tendon and ligament: composition and available scientific evidence
Tendons are ~80% type I collagen. Silicon is a cofactor for the enzymes that assemble this collagen — critical material after micro-tears.
Muscle connective tissue integrity
Fascia, epimysium, and perimysium are collagen and elastin networks that surround the muscle. Collagen and elastin contribute to the mechanical properties of connective tissue.
Joint support during impact
Impact sports put pressure on the knee, ankle, and shoulder. Cartilage contributes to the joint's mechanical cushioning.
Critical post-workout window
The first 24-72 hours are when fibroblasts need raw materials. This is the tissue-remodeling physiological window.

Frequently asked questions about silicon and joints.
01How much sooner will I recover between sessions?+
Athletes who take organic silicon consistently report a 30-40% reduction in the feeling of muscle fatigue between workouts after 4-6 weeks. It's not a stimulant: it's structural. The difference is most noticeable in impact sports, endurance sports, and cross-training, where tissue damage is chronic.
02Can I take it if I have tendinitis, overuse, or pain?+
If you have pain, tendinopathy, or an injury, consult a healthcare professional. This supplement is not intended to treat injuries.
03Can I combine it with magnesium, creatine, or BCAAs?+
Yes, it has documented synergies with zinc (muscle contraction/relaxation), BCAAs and protein (muscle synthesis), and vitamin C (collagen hydroxylation). Creatine works through a different pathway (energy) and can be combined without issue. Just leave 1 hour between taking it and medications to avoid interfering with absorption.
04Is it better before or after a workout?+
Ideally, take it consistently every day, not just once in a while. Silicon builds up in tissue over time; it doesn't work through a single dose. Recommended directions: 15 ml on an empty stomach (G7 Original or liquid Sport Recovery) or 2 capsules with your first meal (G7 Activ+). Apply topically (Sport Recovery Cream or G7 Gel) after exercise to the area you worked: cooling effect.
05What's the difference between silicon and hydrolyzed collagen for athletes?+
Hydrolyzed collagen provides peptides that the body reuses to synthesize its own collagen. Organic silicon is the cofactor that activates the enzymes that assemble these fibers. Collagen and silicon have been studied in connective tissue processes. They complement each other — they're different pieces of the same puzzle.
06Is there a risk of failing a doping test?+
Organic silicon is not on the current WADA Prohibited List (World Anti-Doping Agency). It's a natural mineral, not a stimulant or anabolic agent. The Silicium G7® formula complies with EFSA Novel Food (EU Regulation 2017/2470), pharmaceutical GMP, and batch traceability. If you compete at a federated level, check all ingredients and applicable regulations, and consult your sports doctor.
