Capsule or tablet: what the format changes

Where to start

Shop capsules and tablets by category

Magnesium →NMN and NAD →Vitamins →Amino acids →Herbal →Sleep support →Immune support →Mental wellbeing →Men's health →Skin, hair and nails →Digestion →Sports →Weight management →Powders →All products →

Each category page is in two parts: the products whose nutrients carry an authorised claim, with every claim explained, and the products that have no claim and are sold on what they contain. That split is the same whether the product is a capsule or a tablet.

How we fill and pack

Frequently asked questions

What is the difference between your capsules and your tablets?
A capsule is a two-piece HPMC shell we fill with the powdered ingredient; nothing else goes in, which is why we describe capsules as having no fillers. A tablet is powder pressed under force, and it will not hold together or release properly without binders, a disintegrant and a flow agent, so every tablet carries a short list of excipients. Both formats are declared in full on the label; the difference is what the format needs, not the quality of the ingredient.

Are the capsules vegan?
Yes. The shells are HPMC (hydroxypropyl methylcellulose), a plant-derived cellulose, not gelatin. The contents are the ingredient alone. A few products carry an allergen for another reason, such as soya lecithin in liposomal vitamin C, and those say so on the card and the label.

What capsule sizes do you use?
Size 00 for most single ingredients, holding roughly 500mg to 1,000mg depending on the powder's density; size 000 for the heaviest fills such as the 1,000mg Magnesium and Potassium Citrate; size 0 for lighter or lower-dose ingredients. The size and the fill weight are on each product page, and the fill weight is what we declare, not a rounded figure.

Why do some products come as both capsules and tablets?
Because they suit different buyers. Capsules give you the ingredient with nothing added; tablets hold more active per unit and cost less per serving, which matters on a long-term product like magnesium. Where we offer both, the compound and the elemental figures are the same and only the format and price differ.

Where are they made?
Capsules are filled on our own line at Unit 1, 8 Towerfield Road, Southend-on-Sea, which holds a 5 Star Food Hygiene Rating; we have self-encapsulated NMN there since 2016. Tablets are pressed to our specification by UK contract manufacturers and packed by us. Raw materials come with a supplier dossier and a batch certificate of analysis.

How do I read the amounts on your pages?
Two figures where it matters: the compound and the element. Magnesium bisglycinate 650mg providing 85mg magnesium; zinc citrate providing 15mg zinc; L-arginine HCl 700mg providing about 580mg L-arginine. The elemental or free figure is what the authorised claims are measured against, and it is the one to compare between brands.

Do all of these carry health claims?
No. Vitamins and minerals carry the claims the Great Britain register gives them, in fixed wording, and each product page explains them. NMN, L-theanine, ashwagandha, lion's mane, berberine and the other botanicals and amino acids have no authorised claim and are sold on amount, purity and source. The category pages linked below separate the two.

Can I buy loose capsules or have my own product filled?
Yes. Capsules loose by the thousand, white label in your own pouches, and capsule filling of your ingredient or ours to a target weight. Tablets to 25,000 per line. Use the contact page for a trade price.
