Are you looking for antioxidant food supplements to support your daily wellbeing, boost your cellular energy, strengthen your immunity or improve the health of your skin? The range available in the UK is vast, but labels don't always make it easy to compare formulas at a glance.
Some products boast an impressive dosage without specifying the truly active amount. Others combine several ingredients — astaxanthin, resveratrol, quercetin or liposomal glutathione — without clearly detailing the daily dose. As for formulas labelled "natural" or "vegan", they too deserve a closer look: composition, usage precautions and traceability all need checking.
Here are the key criteria to review before you buy, followed by a selection tailored to different profiles.
A product may claim several thousand milligrams of fruit or plant equivalent, when the actual amount of extract used is far lower. This is particularly true of formulas based on Montmorency cherry: you need to distinguish between the fruit equivalent and the amount of concentrated extract.
To compare two products, always note:
A high dosage doesn't necessarily mean the formula is better suited to your needs. Biotin, for example, may be offered at 10,000 µg per serving, while vitamin C is listed separately, in milligrams and as a percentage of reference nutrient intakes.
Comparison should focus on the whole formula: ingredients, excipients, dosage form, allergens and the manufacturer's recommendations. For vegan supplements, remember to check the composition of the capsule or softgel too, not just the active ingredient being promoted.
A food supplement is not a substitute for a varied diet or a healthy lifestyle. Always follow the dose stated on the packaging and keep products out of reach of children.
Some products require particular caution:
Capsules, softgels, tablets, liquid formulas — they don't all fit into a routine in the same way. A liposomal softgel, such as one containing glutathione, combines the active ingredient with phospholipids. The manufacturer presents this technology as a way to support absorption, but it doesn't guarantee effectiveness for every user.
For skin health, some formulas combine vitamin C, hyaluronic acid, biotin or coenzyme Q10. For immune support, you'll often find vitamin C, zinc, selenium, spirulina or quercetin. These combinations should be assessed with the total dose in mind, especially if you're already taking several supplements.
The total weight of a plant extract doesn't always tell you what it actually contains. Where the information is available, look for the OPC content in grape seed extract, the percentage of trans-resveratrol, or the effective amount of astaxanthin.
Formulas targeting protection against oxidative stress may contain:
These ingredients are not interchangeable. Your choice depends on the composition you're after, the format that suits you and the budget you have in mind.
A bottle of 240 softgels taken at one per day will last several months. Conversely, a product requiring two capsules daily will run out twice as fast. To compare prices meaningfully, calculate the cost per day rather than just looking at the price on the bottle.
Also check storage conditions: some liquid formulas must be used within a specific time after opening, while capsules are generally best kept away from moisture and light.
Why this choice suits this profile: With 180 capsules, this supplement fits easily into a daily routine. It combines a Montmorency cherry extract with a formula that is stated as vegan, free from gluten and artificial flavours.
The product page distinguishes the Montmorency cherry equivalent from the amount of extract used, allowing you to interpret the stated dosage with more perspective.
180 capsules, vegan formulation, free from gluten and GMOs according to the information provided.
Why this choice suits this profile: This formula brings together reduced glutathione, vitamin C, alpha-lipoic acid, hyaluronic acid and phosphatidylcholine in a single daily capsule.
The quantities are detailed for each capsule: 333.3 mg of liposomal glutathione, 66.7 mg of vitamin C and 6.7 mg of alpha-lipoic acid.
Vegan formula, GMO-free according to the product page, with 90 capsules in a discreet format.
Why this choice suits this profile: With 240 softgels and a recommended intake of one per day, this product is ideal for those who want to minimise reordering and avoid running out of an astaxanthin supplement.
The product page specifies the source — an oleoresin from the algae *Haematococcus pluvialis* — as well as the presence of 18 mg of natural astaxanthin per softgel.
240 softgels, formula stated as vegan, free from gluten and lactose according to the manufacturer.
Why this choice suits this profile: Its liquid format may appeal to adults who prefer to avoid capsules and are looking for a formula combining biotin and vitamin C.
The serving is set at 15 ml and the bottle provides approximately 33 servings, making it easier to estimate the cost and duration of use.
10,000 µg of biotin and 80 mg of vitamin C per serving, with a formula stated as vegan, free from gluten and lactose.
We've put together a comprehensive selection, updated in real time, of products that meet these strict criteria as well as European safety requirements.
Compare the presence of vitamin C, biotin, hyaluronic acid or astaxanthin, but pay particular attention to the doses per serving. According to authorised nutrition claims, vitamin C contributes to normal collagen formation. These supplements are not a substitute for dermatological treatments or the advice of a healthcare professional.
This is possible in some routines, but stacking multiple formulas can unnecessarily increase your intake of certain nutrients. Read labels carefully and seek advice from a healthcare professional if you are on medication, pregnant, breastfeeding or have a medical condition.
Always follow the best-before date and the manufacturer's instructions. Capsules should generally be stored in a dry place, away from heat and light. A liquid formula, such as biotin, may need to be refrigerated after opening and may need to be used within a specific time frame stated on the packaging.
