[What is Rhodiola Rosea]

Rhodiola Rosea (also known as Arctic root or golden root) is a member of the family Crassulaceae, a family of plants native to the arctic regions of Eastern Siberia. Rhodiola rosea is widely distributed  in Arctic and mountainous regions throughout Europe and Asia. It grows at altitudes of 11,000 to 18,000 feet above sea level.

There are numerous animal and test tube studies showing that rhodiola has both a stimulating and a sedating effect on the central nervous system; enhance physical endurance; improves thyroid, thymus, and adrenal function; protects the nervous system, heart and liver; and has antioxidant and anticancer properties.

[Function]

1 Enhancing immunity and delaying aging;

3 Regulating nervous system and metabolism, effectively limiting melancholy feeling and mood, and promoting mental status;

4 Protecting cardiovascular, dilating coronary artery,preventing coronary arteriosclerosis and arrhythmia.

In this video, I introduce the topic of carbohydrates / sugars.

(CH2O)n is the general formula for a monosaccharide or simple sugar. Glucose (C6H12O6) is a very common and very important example.

Carbohydrate names end in “-ose”
Aldoses have aldehydes in their straight-chain forms (depicted as Fischer projections)
Ketones have ketones in their straight-chain forms (depicted as Fischer projections)

There are D sugars and L sugars, and the convention is based on the Fischer projections of D-glyceraldehyde and L-glyceraldehyde. The two are enantiomers because they are opposite in absolute configuration at all of their chiral centers (which, in this case, is only one). D-glyceraldehyde has an OH on the right, while L-glyceraldehyde has an OH on the left. Sugars that have their last OH on the right are D sugars; sugars that have their last OH are L sugars. Most sugars that exist in life forms are D sugars.

In the video, I depict the difference between Fischer projections (straight chain sugars) and Haworth projections (sugars in their ring forms). I also briefly mention the idea of anomers as a class of epimers, which are a specific class of diastereomers.

Diastereomers are stereoisomers that differ in at least one, but not all chiral centers.
Epimers are stereoisomers that differ at only one chiral center (they are a subclass of diastereomers).
Anomers are stereoisomers that differ at only one chiral center when that chiral center is specifically the anomeric carbon, the stereocenter that forms when a sugar forms a ring. Anomers are a subclass of epimers.

Why it Works for
F21 is an All Natural Sugar Blocker that helps limit your blood sugar absorption. It consists of different compounds found to have various health benefits, such as L-Arabinose, Coriolus Versicolor Polysacchride, Konjac-Mannan, Magnesium Stearate, Mint flavor: Menthol and Natural Colors. F21 not only does it help promote weight loss, (PSK) boosts your immune system response. In fact, for every gram of F21, you can block up to 20 grams of sugar (sucrose). The formula not only helps promote weight loss, it benefits the digestive system by allowing the blocked sucrose to support beneficial probiotic bacteria while the polysaccharide (PSK) boosts your immune system response.
But how does this formula break down the sugar in our bodies? There are basically three steps:
STEP 1
Sugar (sucrose) enters the body as a whole molecule.
STEP 2
The enzyme “sucrose” separates the sucrose molecule into two individual sugar molecules, Glucose and Fructose, which then enter the blood stream to be used. F21 inhibits sucrose from separating the sucrose molecule.
STEP 3
Instead of the sugars entering the blood stream, the whole sucrose molecule and F21 remain in the digestive tract and become prebiotics.
The main ingredient in F21 is L-Arabinose, which helps prevent sugar (sucrose) from being metabolized in the body. It also helps to satisfy any cravings for sugar. Another ingredient, Polysaccharide (PSK), is an extremely powerful antioxidant and immune-regulatory defender. It’s well researched anti-tumor, anti-infection and anti-inflammation effects help repair damaged cells and support the immune system.
Konjac-Mannan is a natural appetite suppressant. It acts as a trigger signaling your stomach to feel a little more satisfied and can help to reduce hunger cravings.
Prebiotics are indigestible fibers that are food for the probiotics. Both F21 and the whole sucrose molecule remain in the large intestine and become food for probiotics.
Menthol is an organic compound made synthetically or obtained from cornmint, peppermint or other mint oils. Menthol has local anesthetic and counterirritant qualities, and it is widely used to relieve minor throat irritation. It is known to be a powerfully medicinal compound linked to several potential health benefits. Peppermint oil, a natural source of menthol, has been investigated as a treatment for several diseases and conditions.
Magnesium stearate, also called octadecanoic acid, is manufactured from both animal and vegetable oils and this is the reason why some nutritional supplements specify that the magnesium stearate used is sourced from vegetables.
