Royal jelly is also known as Queen Bee jelly. Royal jelly is produced by the workers in the hive to feed the queen bee.
, it is a secretion from the head glands of the honey bee. That developed solely by the diet with royal jelly from the same bee larvae significantly larger queen, has meant that the royal jelly particular action properties are attributed.
Ingredients / composition
The composition of royal jelly was analyzed in detail and explains in part the positive impact on the growth of the queen bee.
royal jelly contains carbohydrates and protein in particular B-vitamins and trace elements. The most important nutrients are thiamine, riboflavin, pyridoxine, niacin, pantothenic acid, biotin, folic acid, sterols, biopterin and neopterin.
Royal Jelly are health-promoting properties attributed.
royal jelly is used in cosmetics and available as a dietary supplement or as an additive in food.
In healthy people to royal jelly enhance physical and mental performance.
According to the advertising messages is the royal jelly to a true miracle cure: Royal Jelly is to have a rejuvenating effect, strengthen the immune system, mood-lifting effect, increase resistance to infection, normalize blood pressure, slow the progression of atherosclerosis and favorably on menopausal symptoms (2) and stress impact.
Quality of royal jelly preparations
So far, there is no uniform standard of quality for the production of royal jelly. The quality and composition can vary greatly depending on the region and therefore manufacturing processes.
A French investigation confirmed as the assumption that alters the composition of royal jelly, when artificial feeding bees with sugar or proteins takes place (16). However, this type of feeding is the rule in many commercially produced royal jelly preparations.
Effect of royal jelly
The previously documented in studies effects of royal jelly relate for the most part on animal studies. The following properties of the active complex was observed (15):
Royal Jelly has a beneficial effect on cholesterol levels and the total lipids in the serum (14).
In animal studies the life expectancy of the animals was increased (5) by taking royal jelly.
Other studies suggest that royal jelly accelerates the healing of skin injuries. Moreover, it seems to stimulate collagen production, which could have a positive effect on the connective tissue.
Peptides from the Royal Jelly showed antibacterial activity against Gram-positive and Gram-negative bacteria (8) in vitro.
In animal studies, a beneficial effect was also described on bone metabolism in osteoporosis (4).
In addition, evidence is available that a fatty acid from the active complex inhibits the growth of tumors (6).
Some studies indicate possible anti-inflammatory (9) and antioxidant (12) properties of royal jelly.
Could continue to be documented in vitro estrogen-like effects (10).
In Graves' disease, an autoimmune disease of the thyroid gland, an immunomodulating effect of royal jelly has been described (1).
Due to the change of the active ingredients, in particular the destruction of the peptides in the digestive process, it is unlikely that the antibiotic, anti-inflammatory or immunomodulating properties in humans following oral ingestion of royal jelly are effective.
Studies on the effectiveness
There are few controlled studies on the effectiveness of royal jelly in humans.
In a smaller study of 15 volunteers was examined whether the daily administration of 6 g of royal jelly over a period of 4 weeks shows a beneficial effect on parameters of lipid metabolism (3 ). Result: Compared with the control group under Royal Jelly taking a significant decrease in total cholesterol and LDL-cholesterol could be documented. The HDL and triglyceride concentrations, however, remained unchanged (3).
The results of an initial investigation on the effects of royal jelly on glucose metabolism make it seem possible that patients could benefit with diabetes or pre-diabetes by the royal jelly application (11). In one study, a German research group the effect of a single administration of 20 g of royal jelly was examined on glucose metabolism of 20 healthy adults. As a result, a significantly reduced rise in blood glucose after a glucose tolerance test (OGTT) are documented (11).
A study of a Serbian working group the effect of a 2-month royal jelly administration on the physical development of 12-year-old football players was (n = 25) tested in comparison to a control group. As a result, it was found that it, a trend towards greater increase of body size and muscle mass were recorded for young footballers players, the royal jelly were used as the comparison group. However, these differences did not reach statistical significance (7). Dosage and duration
In a study with a positive result, a daily dose of 6 g of royal jelly over a period of 4 weeks was applied.
In rare cases, after taking medicines containing queen bees jelly, hypersensitivity reactions occurred. This proved to be allergic reactions to the skin such as redness, rash and itching or reactions to other organs. In these cases were facial swelling, asthma attacks or exacerbation of asthma, vomiting, diarrhea, and blood pressure drop (13). In individual cases occurred in patients with history of hypersensitivity to bee queens jelly anaphylactic shock one that was fatal in one of these cases.
So far there is no convincing trial data on the efficacy of royal jelly. Also, no controlled studies have been published that demonstrate efficacy in menopausal symptoms, osteoporosis and inflammatory diseases. For efficacy in the prevention of tumor diseases or infections, there is no proof. A general increase in performance or improved resilience under everyday conditions, has not yet been documented.
Preliminary studies in humans provide evidence that royal jelly could have a favorable effect on disorders of glucose and lipid metabolism.
before application recommendations for diabetics or patients with hypercholesterolemia can be pronounced , larger controlled studies demonstrating the efficacy are needed.
