Royal Jelly

What is Royal Jelly?

Royal Jelly is a nutrient eaten by queen bees. It is a special substance secreted from the hypopharynx in the head through blood vessels of nutrients digested and absorbed by worker bees 7-10 days old eating pollen and honey. 

If a newly hatched honeybee's larva is born eating royal jelly for three days, it becomes a worker bee with a lifespan of about 1.5 months, or becomes a queen bee if it is born after eating royal jelly for more than 10 days. This queen bee lives for 4 to 5 years and lays 1,500 to 3,000 eggs every day during its life. The tremendous longevity and productive ability of the queen bee is due to the efficacy of royal jelly.

Main ingredients of fresh royal jelly

Fresh royal jelly is composed of water, protein, fat, sugar, and minerals. In particular, it has a high content of vitamin Bs, and the amount of acetylcholine that controls the autonomic nerve in the body is known to be the best among natural substances.

There are many kinds of amino acids, but it is special that it contains R-aminobutyric acid, which is deeply related to brain metabolism. In addition, it contains a significant amount of 10-HDA, which is known to have a powerful anti-cancer action and helps improve blood flow.

Quality of Royal Jelly

The quality of royal jelly is determined by the 10-HDA content level, and the international standard (ISO12824) requires 1.4% or higher. Since royal jelly is a substance secreted by a bee’s body, the quality of royal jelly is determined by the natural environment in which the bees live and the food they eat.

That is why the quality of the royal jelly produced in New Zealand, a natural environment, is the best in the world.

In the 10-HDA, the main active ingredient in the fresh royal jelly level test, Rojel recorded over the range of 3.1%.

These 10-HDA levels of fresh royal jelly are unsurpassed records worldwide.

According to the Korean FDA, 10-HDA must be 1.6% or higher, and in most countries except New Zealand, the level of 10-HDA in fresh royal jelly is in the range of 1.6% to the lower half of 2% level.

Rojel stores fresh royal jelly in frozen state at -20°C immediately after production to minimize the deterioration of nutrients.

When opened after purchase, it needs to be kept in the refrigerator. (Store frozen for 3 years, store in refrigerator 3 months)


The main benefits of royal jelly

Royal jelly increases blood flow by more than 100 times compared to honey, so it improves metabolism and may improve biological resistance and immunity.

It also contains a variety of anti-cancer and antibacterial physiological active substances, including hydroxy-2-decenoic acid (10-HDA) and royalactin, which are special substances only in royal jelly.

A study at New Haven University in the U.S, reported that Royal Jelly has a higher antibacterial power against Staphylococcus aureus and E. coli than penicillin.

Another ingredient, acetylcholine, is known to be a neurotransmitter, which helps improve concentration and is effective for students preparing for tests.

A study published in Advanced Biomedical Research in 2012 showed that royal jelly can also help treat Alzheimer's by protecting the nerves in the brain.

The most well-known active ingredient, 10-HDA, also helps break down or excrete cholesterol and triglycerides by facilitating the secretion of the insulin hormone. Cholesterol and triglycerides are the cause of various adult diseases, and it is known that consumption of royal jelly can improve blood vessel dilation, blood pressure stabilization, high blood pressure and symptoms of diabetes.

Royalactin is known to activate stem cell function to make new cells better and regenerate damaged cells faster. Royalactin acts as a growth hormone to help balance hormones in menopausal women.

In particular, an unsaturated fatty acid called hydroxy-2-decenoic acid has a similar effect to a female hormone, which helps relieve symptoms in pre-menstrual syndrome and menopausal women who lack oestrogen.

It also helps prevent shoulder strain, oedema, myocardial infarction, stroke, and atherosclerosis.

Take about half a tablespoon (about 2 grams) from a wooden or plastic teaspoon each morning on an empty stomach. Dissolve it slowly under the tongue rather than swallowing it immediately to help absorb it in the body.
It has a slightly sour taste due to its acidity (pH 4 level), so if you are trying it for the first time, it is good to mix it with honey. Do not take with sour yoghurt or plum.
Nutrients weaken above 40 degrees Celsius, so avoid drinking in warm water.
If you have asthma or allergies, test a small amount first.

 **Royal jelly has been reported to cause severe allergic reactions and in rare cases, fatalities, especially in asthma and allergy sufferers.**
