What is Quercetin?
Quercetin, a plant pigment found in fruits, vegetables, and even red wine, acts as a powerful antioxidant.
It fights free radicals that damage cells and may offer anti-inflammatory benefits.
Research suggests it may contribute to improved heart health, lower blood sugar, and even allergy relief.
While you can get quercetin from foods like apples and onions, the most efficient way to absorb quercetin is the high concentration chamomile capsules or powder.
How does Quercetin work?
Quercetin capules contain a plant pigment that acts like a cellular shield within your body.
It's a powerful antioxidant that neutralizes free radicals, molecules with an extra electron that can damage cells.
This antioxidant activity may contribute to improved heart health by protecting blood vessels and potentially lowering blood sugar levels.
Quercetin might also help manage allergic reactions by stabilizing cells that release histamine, a key allergy trigger.
Customers praised the high purity and quality of these supplements, noting "fast delivery" and "excellent communication." Used for arthritis, cholesterol, and immunity support. Some shoppers haven't felt effects after 5 months of use, suggesting patience is needed as results may take time to manifest.
I love that they have powder formulations of high purity.
Fast delivery. Excellent communication during delivery. I am very pleased.
I can't say I didn't like it. I used it for problems i.e. arthritis, osteoporosis and cholesterol. I was suggested BEBERINE METABOLIC SUPPORT;QUERCETIN HEART-IMMUNITY -BRAIN and KALOGENAS, I have been taking it for 5 months now, but haven't felt any effect. I will take it for another month, as recommended for 6 months.

cholesterol, arthritis, osteoarthritis, weight loss
Hello, I started the experiment, for cholesterol, joint arthrosis, arthritis of course, and to lose 10kg. I've only been trying for less than a month, so I haven't seen any results yet. I'll try it longer, because miracles don't happen right away.

Tired of cheap plastic or excessive packaging? We’ve introduced Aluminium Tins to offer the best of all worlds: 1. Protection against contamination and UV. 2. 100% recyclability. 3. Low resources for production and transport.
Effectiveness of longevity supplements dramatically depends on correct usage method, dosage and synergy between each other.
Our products have been formulated in collaboration with nutritional experts of UCL (London) to ensure maximum anti-ageing elements absorption into cells.
What is Longevity and Healthy Ageing?
A 200-year-long lifespan – this is not just a slogan, but a realistic goal.
In 1961, American scientist Leonard Hayflick discovered that most human cells are capable of dividing up to 60 times during their lifetime before they die.
With each division, they mutate slightly and lose some of their original DNA epigenome information, making our bodies progressively older and more prone to disease.
Fortunately, scientific advances over the past 20 years have shown that there are ways to slow down – and even reverse – the degeneration process.
Frequently Asked Questions
What are side effects of Quercetin?
Quercetin is usually well-tolerated, but some individuals may experience mild side effects such as digestive upset, headaches, or allergic reactions. To assess individual tolerance, it's recommended to start with a lower dose.
What to choose - powder or capsules?
Advantages of powder:
- Powder allows for precise dosage control, making adjustments easier.
- Powder is generally more cost-effective compared to capsules and can be mixed into various liquids for versatility.
Advantages of capsules:
- Convenience as they are easy to take and require no preparation.
- Capsules also mask the taste of powder, which can be beneficial for those sensitive to flavors.
- Capsules provide consistent intake with pre-measured doses.
Your decision should align with your preferences and lifestyle - opt for powder for cost-effectiveness and dosage control, or capsules for convenience and ease of use.
Can I take Quercetin if I'm already on medication?
For safety, discuss quercetin use with your doctor before starting it, especially if you're on any medications. Quercetin may interact with medications processed by the liver, affecting their effectiveness. It might also lower blood pressure, potentially causing excessive drops when combined with blood pressure medication. While research is ongoing, your doctor can assess your individual health and medications to determine potential risks and benefits of taking quercetin.
How should I store the product?
Please store the product in a cool, dry place, away from direct sunlight. If you live in a very hot climate, please store the product in the refrigerator, otherwise it is not necessary.
Is Quercetin beneficial for heart health?
Yes, Quercetin, a natural antioxidant found in many fruits and vegetables, may support heart health by reducing inflammation, improving blood vessel function, and lowering blood pressure. These benefits can contribute to overall cardiovascular health. However, results can vary, so it's best to consult with a healthcare provider for personalized guidance.
Still not sure where to start?
