Zinc Picolinate 25mg, 50mg or 100mg: Which Strength Is Right for You?
Do you eat little meat, no shellfish and not much cheese, and wonder whether your plate keeps up with a mineral you never taste? Zinc is that mineral, and UK rules authorise eighteen sentences about it, word for word [1]. Zinc contributes to the normal function of the immune system. Zinc contributes to the maintenance of normal skin. Zinc contributes to the maintenance of normal hair. Zinc contributes to the maintenance of normal nails. The NHS names meat, shellfish, cheese, bread and wheatgerm as the main sources of zinc, so a plate light on the first three gives you less of it to work with [2]. One capsule a day gives you a measured amount, whatever is on the plate.
Wondering which one to choose? It’s simple once you have the facts. Our zinc picolinate comes as 25mg, 50mg and 100mg, always just one capsule a day, from about 6.7p a day [3]. This guide explains what zinc picolinate is, what to look for on the panel and which capsule fits your day.

Zinc picolinate 25mg, 50mg or 100mg: which is right for you?
All our zinc capsules carry the same authorised sentences, because the sentences belong to zinc, not to the strength [1]. What differs is how much zinc each capsule gives you.
Zinc picolinate 25mg: 90 days for £5.99
Our Zinc Picolinate 25mg gives 25mg of zinc in one capsule, for 90 days at about 6.7p a day [3]. The label asks you not to take other zinc supplements with it, so it is the one zinc product in your daily wellbeing routine.
Zinc picolinate 100mg and 50mg: more zinc in the same capsule
Want more zinc in the same single capsule? Our 50mg and 100mg capsules give twice or four times the amount, still one capsule a day, at about 7.8p and 8.9p a day [3].
Organic zinc from guava leaf: 50mg in two capsules
Our Organic Zinc 50mg belongs to our organic range and takes its zinc from guava leaf, in two vegan capsules with organic brown rice flour [3].

Taking a zinc supplement with a multivitamin
Already taking a combination product? Our Calcium Magnesium Zinc tablets give 15mg of zinc in one tablet, and our multivitamins give 9mg to 15mg a day [3]. The zinc labels ask you not to add another zinc supplement, so choose one of them as your zinc for the day.
How much zinc do you need a day? What the NHS says
The NHS gives two figures: about 9.5mg a day for men aged 19 to 64 and 7mg a day for women [2].
Zinc in food: meat, shellfish, cheese and wheatgerm
The NHS lists meat, shellfish, dairy foods such as cheese, bread, and cereal products such as wheatgerm as good sources [2]. What zinc does in the body is set out in the authorised sentences quoted in full below: zinc has a role in the process of cell division, and zinc contributes to normal macronutrient metabolism [1].
Zinc picolinate on the label: 25mg and 250%
The nutrition panel shows 25mg of zinc in one capsule, which is 250% of the nutrient reference value, 10mg for zinc [3]. The figure is the zinc itself, not the weight of the zinc picolinate it comes in.
25mg ÷ 250% = 10mg, the labelling reference for zinc · so the 50mg capsule is 500% of it and the 100mg capsule 1,000% · £5.99 ÷ 90 capsules = about 6.7p a day

What is zinc picolinate? Zinc bound to picolinic acid
Zinc picolinate is zinc bound to picolinic acid, and the label names it as the form. The claims do not depend on the form: the register authorises the same sentences for any food that is a source of zinc [1].
Zinc capsules ingredients: what is in each capsule
Ingredients are listed by weight, largest first, and in the 25mg capsule the bulking agent, microcrystalline cellulose, comes before the zinc picolinate [3]. The zinc itself is the 25mg on the panel [3].
Zinc benefits: the claims UK rules authorise
In the UK a food supplement may carry only the health claims authorised on the Great Britain Nutrition and Health Claims Register [1]. A zinc claim needs 15% of the reference value, which is 1.5mg, and every capsule here is far above it.
Every health claim on the Great Britain register passed a scientific review: independent scientists examined the research and the evidence behind it before it was authorised [1]. The law itself says that health claims shall be “based on and substantiated by generally accepted scientific evidence” [4].
Zinc on the label and on the register: the authorised sentences
Seventeen of them are quoted here word for word, in three groups. The first six are about the body’s upkeep.
- Zinc contributes to the normal function of the immune system.
- Zinc contributes to the maintenance of normal skin.
- Zinc contributes to the maintenance of normal hair.
- Zinc contributes to the maintenance of normal nails.
- Zinc contributes to the maintenance of normal bones.
- Zinc contributes to the maintenance of normal vision.
Five are about metabolism, the way the body handles what you eat.
- Zinc contributes to normal macronutrient metabolism.
- Zinc contributes to normal carbohydrate metabolism.
- Zinc contributes to normal metabolism of fatty acids.
- Zinc contributes to normal metabolism of vitamin A.
- Zinc contributes to normal acid-base metabolism.
The last six are about cells, thinking and reproduction.
- Zinc contributes to normal DNA synthesis.
- Zinc contributes to normal protein synthesis.
- Zinc has a role in the process of cell division.
- Zinc contributes to the protection of cells from oxidative stress.
- Zinc contributes to normal cognitive function.
- Zinc contributes to normal fertility and reproduction.
These sentences describe zinc’s role in the body’s normal function. They describe the everyday work zinc does, and they apply in full to all three strengths.
How to take zinc picolinate: one capsule a day with water

90 days of zinc picolinate 25mg
If one capsule a day suits your routine, a pouch of 90 covers three months for £5.99, about 6.7p a day.

Zinc picolinate FAQs
1. What are the benefits of zinc picolinate?
The benefits UK law authorises belong to zinc itself: zinc contributes to the normal function of the immune system, to the maintenance of normal skin, hair and nails, and to normal cognitive function, among seventeen sentences quoted word for word above [1].
2. How much zinc a day do adults need?
About 9.5mg a day for men aged 19 to 64 and 7mg for women [2].
3. Is 100mg of zinc a day too much?
The NHS advises taking no more than 25mg of zinc from supplements a day unless your doctor advises otherwise [2]. Our 50mg and 100mg capsules are above that figure, so follow the label: one capsule a day, no other zinc supplement alongside, and a word with your doctor first if you have a medical condition or take medication [3].
4. What is zinc picolinate?
Zinc bound to picolinic acid, and one of the minerals in our range. The panel’s figure, 25mg, is the zinc itself [3].
5. Zinc picolinate or organic zinc from guava leaf: what is the difference?
The source: picolinate is a zinc compound, and our organic zinc comes from guava leaf, certified organic, 50mg in two capsules [3].
6. Are zinc picolinate capsules vegan?
The pouch front says vegan capsules, the shell is hypromellose and the bulking agent is microcrystalline cellulose [3].
7. Can I take zinc every day?
Yes. Each label gives a daily amount, one capsule of zinc picolinate or two of organic zinc, so they are made for daily use; just don’t take more than the label says [3].
Choose by the amount of zinc you want each day: the Zinc Picolinate 25mg at about 6.7p a day, or, if you’d prefer more in one capsule, the 50mg or 100mg [3]. Whichever you go for, every authorised sentence quoted above comes with it [1].
