Pollen has been highly valued for its properties since time immemorial. Industrious bees collect grains and bind them into golden-yellow clumps to form pollen. One bee has to visit about 80 flowers to collect one single load of pollen. On good, sunny days, a swarm of bees can bring up to 150 grammes of pollen to the hive. Flower pollen tastes delicious in muesli, yoghurt or milk. As a natural vital substance combination consisting amongst other things of carbohydrates, dietary fibres and plant protein, pollen makes a major contribution towards our well-being, and as a supplement to our nutrition.

With regular use of Caffein Hair Growth Tonic Liquid a visible increase in hair density can be achieved, as evidenced by independent studies. Caffein Hair Growth Tonic Liquid is a highly effective combination of caffeine, biotin (vitamin H), linoleic acid (Vitamin F), tocopherol acetate (vitamin E) and D-panthenol (pro-vitamin B5). Caffein increases the microcirculation and thus the nutrient supply to the scalp. It activates the hair roots and the cell division, improves hair growth, extends the growth phase and protects the scalp from the harmful effects of testosterone. Encapsulated in the liposome carrier system, the highly effective active complex is transported into the hair shaft and hair follicle where it can develop its full spectrum. Biotin has a positive effect on the metabolism of keratinocytes, as long as it can be transported into the deeper hair roots (papillae). Linoleic acid (Vitamin F) contained a in high concentration in the membranes of liposomes, acts as carrier system and plays a role in the synthesis of ceramides 1 and 2, which again improve the mechanical stability of the hair. Pro-vitamin B5 has the positive quality to thicken and to regenerate damaged hairby up to 10 percent , while vitamin E acts as an antioxidant, thus slowing the photooxidative degradation process of the keratin and hair pigments.

With caffeine complexWith this high-quality hair regulator we succeeded in developing a compound, that contains high-quality non-hormonal natural products in liposomes which prolong the hair's period of growth and so prevent early hair loss. A hair growths 2 to 6 years, then enters to a 3 months respite from growing and afterwards falls out. A new hair grows from the base of the follicle, It can only happen 10 to 12 times in your life that a new hair grows from each base of the follicle, because then. Out of the follicle a hair can grow only 10 to 12 times in a lifetime, after that the regenerative ability of the hair follicle is permanently eliminated.The problem is that of the growth phase lasts for a short period only. Man's hair growth phase lasts at worst for 2 years, then it is already finished after 20 to 24 years. That means, the shorter the growth phase the earlier the hair falls out and the longer the hair's growth phase, the hair will grow for a longer. At this point, the Iso-Silvan Hair Growth Regulator comes into use. It has during the hair growth cycle a preserving effect on the energy balance and thus prevents the early standstill of the energy production of the hair growth cells.

Ähnliche Suchbegriffe für Oxygen:
-
What are oxygen-containing and oxygen-free acids?
Oxygen-containing acids are acids that contain oxygen in their chemical structure, such as sulfuric acid (H2SO4) and nitric acid (HNO3). These acids typically have higher acidity due to the presence of oxygen atoms. On the other hand, oxygen-free acids do not contain oxygen in their chemical structure, such as hydrochloric acid (HCl) and hydrobromic acid (HBr). These acids tend to be less acidic compared to oxygen-containing acids.
-
What is the difference between atmospheric oxygen and oxygen?
Atmospheric oxygen refers to the oxygen that is present in the Earth's atmosphere, which is essential for the respiration of living organisms. On the other hand, oxygen refers to the chemical element with the symbol "O" and atomic number 8, which is a colorless, odorless gas that is essential for life. In essence, atmospheric oxygen is a specific form of oxygen that is present in the air we breathe, while oxygen refers to the element itself.
-
Does oxygen swim?
No, oxygen does not swim. Oxygen is a gas that is essential for life and is present in the air we breathe. It does not have the physical properties or characteristics required for swimming, as swimming typically refers to the act of moving through a liquid medium using limbs or fins.
-
Is oxygen healthy?
Yes, oxygen is essential for human life and is necessary for the body to function properly. It plays a crucial role in the process of respiration, where it is used to produce energy for the body. However, too much oxygen can be harmful and lead to oxidative stress, which can damage cells and tissues. It is important to maintain a balance in oxygen levels to ensure good health.
-
Which oxygen pump?
The oxygen pump is a device used to circulate and distribute oxygen in an aquarium or fish tank to ensure that the fish have enough oxygen to breathe. It helps to maintain the proper oxygen levels in the water, which is essential for the health and well-being of the aquatic life. There are different types of oxygen pumps available, such as air pumps, water pumps, and battery-operated pumps, each serving the same purpose of oxygenation in the aquarium.
-
Is oxygen odorless?
Yes, oxygen is odorless. It is a colorless, odorless, and tasteless gas that is essential for life. While it is a crucial component of the air we breathe, it does not have a distinct smell.
-
How many liters of oxygen are in an oxygen tank?
The amount of liters of oxygen in an oxygen tank can vary depending on the size of the tank. Common sizes of oxygen tanks include 415 liters, 682 liters, and 907 liters.
-
What is the difference between oxygen deficit and oxygen debt?
Oxygen deficit refers to the initial period of exercise where oxygen demand exceeds oxygen supply, leading to anaerobic metabolism. Oxygen debt, on the other hand, is the amount of oxygen required to restore the body to its pre-exercise state after the exercise is completed. Oxygen debt is typically higher than the initial oxygen deficit as the body needs to replenish energy stores and clear accumulated lactic acid.
-
How are oxygen saturation and oxygen in the blood related?
Oxygen saturation refers to the percentage of hemoglobin in the blood that is saturated with oxygen. This means that oxygen saturation is a measure of how well oxygen is binding to hemoglobin in the blood. Therefore, the higher the oxygen saturation level, the more oxygen is being carried by the blood. In other words, oxygen saturation is a direct reflection of the amount of oxygen present in the blood.
-
What are the medical terms for low oxygen and high oxygen?
The medical term for low oxygen levels in the blood is hypoxemia. This condition can lead to symptoms such as shortness of breath, confusion, and rapid heart rate. On the other hand, the medical term for high oxygen levels in the blood is hyperoxemia. This condition can also have negative effects on the body, such as oxygen toxicity, which can damage the lungs and other organs.
-
What exactly do the oxygen partial pressure and oxygen saturation indicate?
The oxygen partial pressure indicates the pressure of oxygen in the blood, specifically the amount of oxygen dissolved in the blood. It is an important measure of how well the lungs are able to oxygenate the blood. Oxygen saturation, on the other hand, indicates the percentage of hemoglobin in the blood that is saturated with oxygen. It provides information on how effectively oxygen is being carried from the lungs to the rest of the body. Both measures are crucial in assessing a person's respiratory and circulatory function.
-
How much does the oxygen level in an oxygen tank decrease?
The oxygen level in an oxygen tank decreases as the tank is used. The rate of decrease depends on the flow rate at which the oxygen is being delivered. Higher flow rates will deplete the oxygen more quickly, while lower flow rates will make the oxygen last longer. It is important to monitor the oxygen level in the tank and replace it when it gets low to ensure a continuous supply of oxygen.
