Royal jelly is a creamy white substance with a high nutrient content that young bees make to feed queen bee larvae. There are claims that it offers a range of health benefits, such as easing the symptoms of premenstrual syndrome and supporting wound healing.
Royal jelly is highly nutritious and may have antibacterial, antioxidant, and anti-inflammatory properties. These properties may be responsible for many of the health claims about royal jelly. People usually consume it orally or apply it directly to the skin.
The nutritional content of royal jelly is a potential benefit in itself as the substance provides a range of essential nutrients that are necessary for good health. Royal jelly comprises:
- water (50 to 60 percent)
- proteins (18 percent)
- carbohydrates (15 percent)
- lipids (3 to 6 percent)
- mineral salts (1.5 percent)
There are small amounts of vitamins and minerals in royal jelly, including several types of vitamin B. It also contains some polyphenols, which are a type of plant-based chemical that is rich in antioxidants.
Royal jelly may provide relief from the symptoms of menopause
A 2011 study looked at the effect of a combination of four natural ingredients, including royal jelly, on menstrual symptoms. The researchers gave 120 women either a capsule containing the four ingredients or a placebo twice a day over 4 weeks.
The women in both groups noted a reduction in symptoms, but those who took the capsule had significantly better results than those in the placebo group.
A more recent study found that taking 150 milligrams of royal jelly daily over 3 months could help improve cholesterol levels in healthy postmenopausal women.
Royal jelly may also be beneficial for people with premenstrual syndrome.
In a 2014 study, the investigators gave 110 participants either a royal jelly capsule or a placebo once every day over two menstrual cycles. The participants who took the royal jelly capsules had less severe premenstrual syndrome symptoms over the 2 months.
According to some research, royal jelly could speed up the process of wound healing.
The results of a laboratory study in the journal Nutrition Research and Practice showed that royal jelly might significantly increase the movement of fibroblasts to a wound. Fibroblasts are a type of cell that coordinates the process of wound healing.
Type 2 Diabetes
There is some evidence that royal jelly may have benefits for people with type 2 diabetes
In one study, 50 female participants with type 2 diabetes received either a 1-gram dose of royal jelly gel or a placebo once a day for 8 weeks.
The results indicated that taking royal jelly may lead to a reduction in the level of blood glucose. Lower glucose levels in the blood are beneficial for people with type 2 diabetes.
However, the researchers note that more studies with a larger number of participants are necessary.
