Uses, Health Benefits, and Risks

• What the Science Says
• Side Effects Unknown

Maybe you’ve heard the claim that raspberry ketone supplements can melt away fat and prevent weight gain — even if your diet is high in fat. But what are they, and can they really do that?

Raspberry ketones are natural chemicals that give raspberries their enticing aroma. When ketones are taken from raspberries, they can be used to add fragrance and flavor to things such as colas, ice cream, and cosmetics.

Experts say that investing in a bottle of raspberry ketone supplements amounts to little more than wishful thinking. And it may or may not be harmful.

In one small study, people who took 200 milligrams of raspberry ketones combined with 1,200 mg of vitamin C daily for 4 weeks lost weight and body fat. But the study did not follow good scientific methods. It doesn’t show whether any benefit was from either the vitamin C or the raspberry ketones or from the combination. Until more is known, experts say you’re better off holding onto your money. Instead, stick to a healthy, balanced diet and regular exercise. Both of those have been shown to be effective ways to manage weight.

Raspberry ketones in food and cosmetics are generally considered safe. But no one knows what short- or long-term effect raspberry ketone supplements could have on your overall health. No study has been done to document potential side effects. There are also no studies that look at potential drug or food interactions.

The fact that raspberry ketones chemically resemble other stimulants suggests the potential for certain side effects. And there are anecdotal reports of jitteriness, increased blood pressure, and rapid heartbeat among people taking raspberry ketone supplements. Without scientific evidence, no one can say what dosage of raspberry ketone supplements, if any, might be safe to take.

Talk to your doctor about any supplements you’re thinking about taking, and any concerns you have about your weight or weight loss.

Raspberry Ketone, 10g | HomeArt

Raspberry ketone

INCI: 4-(n-hydroxyphenyl)-2-butanone

Appearance – White needles or granules.

Synonyms: oxyphenylone, frambinone

Description: a natural phenolic compound that is the main component of the aroma of red raspberries (Rubus idaeus). In nature, it is found in its essential oil. This chemical structure is similar to zingerone, which is extracted from ginger and has been shown to reduce obesity. In addition, raspberry ketone is similar to capsaicin (a chemical found in hot chili peppers that has fat-burning properties), synephrine (a compound found in orange peel and known to reduce fat and fluid retention), and evodiamine (another fat-burning ingredient). All of these chemicals, including raspberry ketone, interact with fat cells and cause fat loss through similar mechanisms. In plants, raspberry ketone is synthesized from coumaroyl-CoA. The extraction of pure raspberry ketone is typically 1-4 mg/kg raspberries.

Physical:

Appearance: colorless crystals, white crystalline powder

Molecular mass: 164.20

Formula: C10 h22 O2

Density: 1.088 ± 0.06 g/cm3

Refractive index: 1.535 ± 0.02

Melting point: 83 – 84°C 9000 3

Boiling point: 161°C

Autoignition point: 195°C, may ignite easily if overheated.

Solubility: soluble in alcohol, dipropylene glycol, propylene glycol, oils, slightly soluble in water, insoluble in vaseline oil, isopropyl myristate.

Cosmetic use: Raspberry ketone is chemically similar to capsaicin, a component found in red peppers. But unlike it, it does not irritate the skin, does not cause burning and redness, and can be used even with sensitive skin. It has no documented side effects associated with consumption and may even be more thermogenic than capsaicin.

Raspberry ketones stimulate hormone-dependent fat breakdown in fat cells. As a result, there is a decrease in the volume of subcutaneous adipose tissue, even with a diet high in lipids.

Obesity and cellulite treatment: Japanese scientists have discovered the ability of raspberry ketones to speed up metabolism and allow the body to safely dispose of excess calories and already accumulated fat deposits. The process of fat burning does not affect the muscles, but gives them a beautiful shape, because. in the process of utilization, fat is split, which is not only in the fat depots on the abdomen and thighs, but also the fat accumulated by the body between muscle fibers and internal organs.

Accelerates metabolism by increasing body temperature, both general and local. Increases the production of the main fat-burning hormones – epinephrine and norepinephrine.

Prevents the destruction of fat-burning hormones, allowing them to act in the body permanently. Prevents the stoppage of the work of alpha receptors of fat cells, also stimulating their constant activity. It is the shutdown of the alpha receptors of fat cells that causes the body to accumulate fat, and not expend it on energy production.

One of the main advantages along with fat-burning properties is the elimination of skin laxity. Increases skin tone and elasticity.

In facial cosmetics, it helps to narrow pores, optimizes metabolic processes, and has a rejuvenating effect.

The relevance and value of hair cosmetics is closely related to their ability to have a general strengthening effect on the hair, stimulate its rapid growth and prevent signs of early hair loss.

Properties:

Removes congestion, accelerates the circulation of mucus.

Eliminates sagging skin, speeds up metabolism and allows the body to safely utilize excess calories and already accumulated fat deposits. The process of fat burning does not affect the muscles, but gives them a beautiful shape.

Gives skin smoothness and elasticity, stimulates metabolism, rejuvenates and tones.

Helps cleanse and protect the skin from environmental damage.

Ideal for skin care in the eye area, as it helps to gently restore delicate skin.

Good for oily skin with enlarged pores.

Accelerates hair growth and prevents hair loss.

Application:

– Soap and shower gel with anti-cellulite action

– Soaking washcloths for the same purpose

– Taking raspberry ketone capsules to burn fat before the competition

– Sprays and tonics to combat baldness and improve skin elasticity

– Shampoos and hair masks

– Anti-cellulite creams and gels

– Gels to enhance the growth of eyelashes and eyebrows

– Creams and gels for the skin around the eyes 9 0003

Recommended dosages:

The cosmetic dosage of adding raspberry ketone to the prescription composition is from min. 0.02% to 5%, or 5% to 10% (in this case, raspberry ketone dissolves exclusively in diethyl phthalate):

• anti-cellulite products (serums, wraps) – up to 1%;
• cosmetics for the skin of the face (including the area around the eyes0 – up to 0.5%;
• anti-baldness products – 0.02%;
• shampoos, other foamy detergents – up to 2%;
• gels to enhance eyelash growth – 0.01%.

Basic rules for adding raspberry ketone to cosmetics (alcohol is pre-weighed):

• 8 g of alcohol.
• To create 100 g of a 10% Raspberry Ketone solution, it is recommended to dissolve 10 g of this agent in 90 g of alcohol.
• To create 100 g of a 5% raspberry ketone solution, it is recommended to dissolve 2.5 g of this agent in 48 g of alcohol.

Administer in the final phase of the preparation of the cosmetic product.

When introducing raspberry ketone into oils, it is necessary to introduce it at the stage of the fatty phase of preparation (oils + emulsifier) ​​and then heat until completely dissolved.
