Silizium/Silicon

Allgemeines
Silizium ist ein Halbmetall und in seiner Eigenschaft als Halbleiter geradezu berühmt geworden. Es besitzt die Ordnungszahl 14 im Periodensystem der Elemente und die Abkürzung Si. Es ist nach dem Sauerstoff das zweithäufigste Element auf der Erdoberfläche. Silizium kommt in der Natur nicht elementar vor. Es ist in zahlreichen anorganischen Mineralien, wie z.B. dem Quarz (Sand), Feldspat, Glimmer oder dem Turmalin enthalten. Etwa 90 % der Erdkruste bestehen aus Siliziumverbindungen.
1823 wurde Silizium von dem schwedischen Chemiker Jöns Jakob Berzelius (1779 - 1848) aus Siliziumtetrafluorid gewonnen.
Silizium wird vor allem in der Halbleitertechnik, sowie in Sonnenkollektoren und Batterien verwendet. Glas wird aus Siliziumverbindungen (Quarzsand) hergestellt. Außerdem wird es als Sand für jedes Bauwerk benötigt. Weiterhin ist Silizium ein Hauptbestandteil von Silikon, das neben Silizium die Elemente Kohlenstoff und Sauerstoff enthält. Im Körper wird Silizium vor allem in Bindegeweben und Knochen eingelagert.

Mangelerscheinungen
Ein Siliziummangel kann zu Wachstumsstörungen und einer Reihe von Hauterkrankungen wie chronischen Ekzemen und Juckreiz (Pruritus) führen. Brüchige Nägel und Haarausfall können auch Symptome eines Siliziummangels sein. Ernstere Folgen bestehen möglicherweise in einer verminderten Elastizität bestimmter Anteile der Blutgefäßwände infolge Kollagenmangels und in Osteoporose.

Bedarf
Der tägliche Bedarf wird auf 40 Milligramm täglich geschätzt. Silizium ist vor allem in pflanzlichen Lebensmitteln wie Kartoffeln, einer Reihe von Getreidesorten, Spinat und Obst enthalten.

It promotes strength and performance, is obtainable at our shop without a prescription and is not on the list of prohibited substances of any of the international sports organizations such as the IOC (International Olympic Committee). Creatine is a natural molecule that can be found in a range of (mostly animal) foods.

Many men want to have a toned upper body and a six-pack and more and more women acquire a liking for a lean and muscular physique. Yet despite the fact that resistance training alone produces astonishing results within a short period of time, the fat tissue on the abs, legs, hips and the butt tends to be particularly stubborn. No matter how hard you train, the fat simply won’t vanish. In this case, a fat burner can help. Fat burners are designed to promote your metabolism. The majority of the products will increase your body temperature and help transport the fat from the adipose tissue into your muscles, where it can be burned as fuel while you train. The combination of various ingredients in the fat burner caps ensures that your newly acquired muscles will get toned and the unwanted fat stores will vanish. The selection of different fat burners on the market is huge, just as the qualitative differences between the products. To find the right product for you, it is advisable to take a closer look at the ingredients. While all products claim to have more or less the same effect, i.e. increasing energy expenditure and burning fat, their ingredient profiles vary. As with all nutritional supplements, it is thus of paramount importance to pay attention to the quality of the product to avoid unwanted side effects and ward off serious damage to your health. We at Gigas Nutrition sell only tested originals and no rip-offs! Go visit our online shop and see for yourself: Quality does not have to be expensive! With the unique Gigas Best Price and Gigas Lowest Price Guarantees you can be sure to buy your fat burners at the best prices on the Net!

While nutrition usually comprises everything related to food, it can also refer to the use of nutritional supplements in strength and endurance sports, in particular. An increase in the amount of vitamins, minerals, protein, and – over the last years – creatine by the regular consumption of respective products is a completely natural way to augment muscle growth. The ingestion of these supplements facilitates a faster and more efficient oxygen supply to the trained muscles. Your strength and energy during training will improve and your workouts will become more effective. In this context, vitamins, amino acids, proteins and creatine all have their specific properties, which make them more or less valuable for athletes depending on which sports they play. With appropriate supplementation, a strength athlete, for example, can specifically increase muscle growth and prevent nutrient deficiencies, which could occurs subsequent to longer periods of intense training. When you buy supplements, it is however strongly advisable not to buy the next best caps, pills and powders you can find. Quality is what really counts, which is why you should buy only from reputable producers. Gigas Nutition offers only products from renowned manufacturers such as Olimp Sport Nutrition, BSN, Scitec Nutrition, Optimum Nutrition, Dymatize, Muscle Tech, Ironmaxx and many more. The current Top 5 Selling Brands are always listed right on our homepage. Maybe your favorite brand is one of them. Stop by and take your time to browse the huge range of premium dietary supplements the Gigas Nutrition Megastore, Your Online Shop for Sports Nutrition, has to offer.

You should not miss out on a protein shake, right after your workout! It contains, as the name implies, valuable protein, a nutrient your body needs to build muscle in the course of and following your workouts. To replenish your protein reserves after a hard training session, a protein shake should thus be your first choice. As a rule of thumb, you can assume that you will need an additional 1g (max. 1.5g) of protein powder per 1kg of body weight per day. This will secure an optimal protein supply and increase the effectiveness of your workouts. The individual amino acids, i.e. BCAA’s, arginine and glutamine in protein shakes have been shown to improve performance, accelerate regeneration and improve muscular hypertrophy, significantly. Moreover, the slower digestible proteins like egg protein and above all casein, which are gradually released into the bloodstream, will supply your muscles with muscle building amino acids for hours. We carry a broad range of protein powders that will help you build muscle and improve your performance in the gym, at very reasonable prices. Visit our online store and check out which protein shake suits you best. Depending on its texture and ingredients, the protein powder can be blended with skim milk or water. By using a special shaker bottle, such as the Shaker Pro 40, or an electrical blender you can make sure that the powder blends into a creamy milkshake-esque beverage. You can find both, shaker bottles and electrical blenders listed under “Accessories” in the main menu of our online store.
