Green Tea

What are the health and weight-loss benefits of green tea?

Latin name: Camellia sinensis L.

Botanical family: Theaceae

Part used: Leaf

All teas contain caffeine and polyphenols (antioxidants from the flavonoid family). Caffeine is a substance in the methylxanthine family found in many plants: coffee, cacao, kola, guarana, mate, etc. Caffeine stimulates the nervous system, thereby increasing alertness and mental focus. It suppresses appetite, slightly increases basal metabolism (the body’s energy expenditure at rest), and stimulates urine production.

Tea is rich in polyphenols: catechins (in particular, epigallocatechin-3-gallate, or EGCG), theaflavins, thearubigins, etc. These substances are antioxidants that can protect cells from chemical damage. In cell cultures, EGCG has shown a definite ability to inhibit the growth of several types of cancer cells. It is believed that this effect is linked to its antioxidant properties and its ability to inhibit an enzyme necessary for cancer cell growth, urokinase.

Tea’s effect in preventing tooth decay may be linked to catechins, but also to its high fluoride content.

Is green tea effective for sustainable weight loss?

In adults, caffeine intake of 60 mg or more is associated with increased mental alertness and increased urine output. The effects of caffeine on appetite and basal metabolism are limited and disappear in people who consume it regularly. No long-term studies confirm any lasting effects of caffeine or tea on weight loss. Soin et Nature therefore offers a carefully curated selection of products made from green tea (Camellia sinensis L.), known for its antioxidant, detoxifying , and stimulating properties — ideal for supporting weight-loss regimens, promoting fat metabolism, and supporting overall well-being. Our organic dietary supplements and herbal teas, sourced from trusted pharmaceutical brands, combine natural ingredients, effectiveness, and safety for a holistic approach to your daily health.

Studies on the preventive properties of tea in relation to cardiovascular diseases or cancers have yielded conflicting results. These are primarily observational studies that may (or may not) show a lower risk of developing these diseases among people who naturally consume large amounts of tea. However, the influence of other factors (such as diet or a healthier lifestyle in general) is almost never taken into account. In the context of cancer prevention or treatment, no study has clearly demonstrated a benefit from drinking tea. Studies are currently underway in the United States to evaluate its effects on skin cancer.

Studies on the effects of tea in preventing dental caries warrant larger-scale studies to confirm the observed benefits. Other proposed uses for tea have not been scientifically evaluated.

Tea and Precautions for Use:

• People with heart conditions, insomnia, anxiety disorders, high blood pressure, stomach or kidney problems, or osteoporosis should limit their intake of tea and caffeine.
• People with diabetes should also avoid consuming large amounts of tea or caffeine, as caffeine appears to cause an increase in blood glucose levels, particularly in the evening
• Excess caffeine causes numerous side effects: nervousness, restlessness, anxiety, heart palpitations, insomnia, stomach irritation, diarrhea, etc. Regular consumption of high doses of caffeine leads to dependence, and withdrawal from it can cause headaches, drowsiness, nervousness, anxiety, and irritability. In extreme cases, a caffeine overdose can cause serious muscle disorders (rhabdomyolysis)
• Caffeine can interact with many other substances. The main interactions involving caffeine are with certain antibiotics, theophylline, and products containing ephedra
• Certain antibiotics in the quinolone family (ciprofloxacin, enoxacin, norfloxacin) and, to a lesser extent, alcohol, female hormones, and birth control pills slow the elimination of caffeine and increase the risk of its side effects. Theophylline, a substance used to treat asthma, has the same side effects as caffeine. Taking them together increases the risk of palpitations, agitation, tremors, etc.
• Products containing caffeine should never be taken with plants containing stimulant substances similar to amphetamines, such as ephedra (Ephedra sinica, which contains ephedrine) or bitter orange (Citrus aurantium or bitter orange, which contains synephrine), due to an increased risk of cardiovascular events (myocardial infarction). Caffeine also increases the absorption of aspirin and acetaminophen, promotes nicotine dependence from tobacco, and may enhance the effects of medications and herbs with anticoagulant properties.
• Finally, caffeine may reduce the effectiveness of certain antacids (used to treat heartburn), alendronic acid (a substance used to treat osteoporosis), and clozapine (an antipsychotic).
• The tannins in tea can reduce the absorption of iron in the intestines. It’s best to drink less than two liters of tea per day, and to avoid drinking it with meals or when taking iron supplements.
• Pregnant and breastfeeding women should limit their caffeine intake to less than 200 mg per day, as caffeine passes into the fetus’s bloodstream and into breast milk. Higher intake has been linked to an increased risk of miscarriage and low birth weight. In addition, caffeine increases the excretion of calcium and magnesium in the urine, which can lead to deficiencies.
