Main Highlights

UNLEASH YOUR OWN COLLAGEN: LIVING SILICA Mineral-Based Collagen Booster Liquid supports your own body's collagen, keratin, and elastin levels.

THE MOST EFFECTIVE FORM OF SILICA: No other colloidal silica, silicic acid or plant extract-based silica supplements in the marketplace provide higher bioavailability than LIVING SILICA. When you absorb more silica into your body, youre able to generate more collagen. The problem is that most people consume collagen to get its ultimate effects.

LIVING SILICAs is fully utilized by the body instead of being expelled. LIVING SILICA reaches the collagen-producing cells and activates them, which promotes their collagen production.
CLINICALLY BACKED: Clinical studies have demonstrated impressive results on the health of skin, hair, and nails, as well as on bones and joints, further confirming LIVING SILICA's effectiveness. It has been very effective in providing quick and visible results in a short time thanks to its assimilation.
HIGHEST QUALITY STANDARD: LIVING SILICA is vegan friendly & free of GMOs, soy, dairy, egg, corn, wheat, gluten, fish/shellfish, peanuts/nuts/tree nuts, animal-derived ingredients, artificial colors, or any flavors or sweeteners.

Main Highlights

DOUBLE STRENGTH FORMULA! We created our Double Strength Silica Complex to contain at least twice the amount of Silica as most of our competitor products. To achieve this we packed each tablet full of a massive 500mg Horsetail extract - equivalent to 2000mg horsetail. Our Horsetail provides a natural source of Silica at a rate of 10% meaning each tablet provides you with 200mg of the finest natural Silica.
COMPREHENSIVE NUTRIENT BLEND We covered all the bases by creating the ultimate stack of essential minerals. Our bespoke complex contains optimum concentrations of Manganese(15mg) , Boron (2mg) and Zinc (15mg). These essential nutrients work in synergy with Silica to ensure maximum effectiveness with minimal effort.
ALL NATURAL FORMULA - Our Silica is derived from the all-natural Horsetail Plant. Horsetail has been used for centuries to support Joint care and promote skin, hair and teeth. By packing our tablets full of Horsetail extract we aim to ensure you get the maximum possible Silica dose, and you don't need to rattle like a pill bottle to do so. You only need take one tablet per day!
EXCEPTIONAL VALUE 90 tablets per bottle - you only need to take 1 tablet per day. Each bottle lasts 3 months and at this price, if you were to compare it mg per mg to any of our competitors you might be angry that youve spent so much more in the past on other companies lower strength products.
