Good-sized capsules, although they are on the larger side. Nice dosage and with vitamin C.
Ik gebruik het aan de einde van de winter tot begin zomer. Altijd in combinatie met scutellariae. Deze combinatie doet wonderen. Ik heb geen last van de lastige kwalen van het voorjaar.
Excellent product for me Both in terms of energy and immune system I think it has also somewhat improved {***} I have a check-up every year, and it had dropped by 1 point after years 💁♀️
Since I started using this during pollen seasons, I've had much less trouble with my airways. It works really well for me.
I have suffered a lot from hay fever, especially between May and August (grass pollen). Since I started using Quercetin, I have hardly had any symptoms and can go outside all year round without taking any precautions.

I read on a health website that taking this supplement is not really necessary as it is present in various vegetables and fruits. Moreover, it was suggested that taking this supplement could even cause [.....] instead of having a positive effect. The question is, is there a kernel of truth in this or is it completely unfounded? I would appreciate your response.
On 10 may 2019 by Customer service100 grams of red grapes provide approximately 2 mg of quercetin. To reach the equivalent of one 500 mg capsule, you would therefore need to consume 25 kilograms of grapes daily. Raspberries contain a slightly higher percentage of quercetin, around 3.5 mg per 100 grams. Thus, you could opt to eat 15 kilograms of raspberries each day.
In some cases, a higher dose of quercetin is desirable, specifically 1000 mg. To achieve that dose, you would need to consume 50 kilograms of grapes or 30 kilograms of raspberries.
It is clear that this is not practical. Firstly, you would be consuming far too many carbohydrates, and secondly, it would be prohibitively expensive.
Quercetin may interact with chemotherapy. Therefore, it is advised not to use quercetin during such treatment. Those not undergoing chemotherapy can safely take quercetin in doses ranging from 500 to 1500 mg per day, with no known adverse effects. I suspect that the statement you read is based on a misunderstanding.
Hello, I am 52 years old and would like to start with Ultimate Bone Support. Can this be combined with Quercetin?
On 19 may 2025 by Customer serviceYes, these supplements can be combined without any issues. They each have a different area of effect.
What type of gelatine is used in the quercetin capsule?
On 08 april 2025 by Customer serviceThe capsules are plant-based, made from hydroxypropylmethylcellulose. This means they contain no animal gelatine and are entirely suitable for vegetarians and vegans.
Good day, I'm really quite adept at taking medication. Can I open these capsules and take the contents with yoghurt or something similar? Kind regards, Judy
On 03 april 2025 by Customer serviceYes, the capsules can be opened. Please bear in mind that the powder may have a bitter taste. You can mix it with some yoghurt, juice, or a smoothie if you prefer.
May I take quercetin in combination with rosuvastatin? (This is a medication for high cholesterol)
On 27 may 2024 by Customer serviceThe impact of supplements on your cholesterol is generally negligible or mild in nature. In the long term, it is possible that your cholesterol may slightly decrease or increase. We therefore advise that when you go for a check-up with your (GP) doctor, you also have your cholesterol measured.
