Every claim on this site, and where it comes from
One standard runs the whole shop. A health claim is printed only in the wording the GB register authorises for that nutrient, next to the amount in the daily portion that earns it. Everything else in the capsule is described by its composition: the species, the extract, the standard it is held to and the amount, where one is published.
This page is that standard laid out in full, ingredient by ingredient, across the whole range. It is here so any sentence on any product page can be checked against its source before you buy, without taking our word for it.
The scalp serum is a cosmetic rather than a food supplement, so the nutrition and health claims register does not reach it. It is read under cosmetic wording and sits in its own section further down. The Glow Stack carries both kinds at once, two food supplements under the register and that serum under cosmetics rules, so its entry here is read under both, part by part.
The nutrients the register names
These are the only nutrients in the range with an authorised GB entry attached to them, and this is that entry, quoted in the register's own wording. The amount beneath a claim is the amount in the daily portion that stands behind it.
| Nutrient | What is authorised, in the register's own wording | Where it appears |
|---|---|---|
| Biotin |
“contributes to the maintenance of normal hair and normal skin.” The register's biotin entry reaches hair and skin, so the pages reach exactly that far and no further. In two gummies: 6000 µg of biotin. |
Biotin GummiesThe Glow Stack |
| Magnesium |
“contributes to a reduction of tiredness and fatigue.” “contributes to normal muscle function, normal psychological function and the normal functioning of the nervous system.” In three capsules: 275 mg of magnesium, 73% of the daily reference intake. One mineral, with entries on both the physical and the mental side. The figure is what earns them, rather than the word on the label. |
Magnesium Glycinate |
Where a nutrient benefit is named above, it is an authorised UK health claim for that nutrient. Food supplements should not replace a varied, balanced diet and a healthy lifestyle. If you are pregnant, breastfeeding or taking medication, speak to your GP before use.
Described by composition
The register speaks to nutrients. Everything below is set down the way a specification sets it down instead: the species, the extract, the standard it is held to, the shell it sits in and the amount, where one is published. That description is the whole of what a Kolvi page says about these, and it is repeated here without addition.
| Ingredient | What it is | Where it appears |
|---|---|---|
| Ashwagandha root |
A full-spectrum root extract of Withania somnifera, sitting in a pullulan shell fermented from tapioca, so the whole capsule is plant-based with no gelatine. Sixty capsules per bottle. One capsule twice a day with a glass of water, ideally twenty to thirty minutes before a meal. |
Ashwagandha Capsules |
| Black pepper |
Organic black pepper, the traditional pairing for the root extract, in the same capsule. |
Ashwagandha Capsules |
| Lion’s mane |
Hericium erinaceus, fruiting body and mycelium, standardised to 40% polysaccharides. Sixty vegan capsules per bottle. Two with breakfast. |
Lion’s Mane Capsules |
| Irish sea moss |
Organic Irish moss, organic bladderwrack, organic burdock and BioPerine, a black pepper extract, in a pullulan capsule. No gelatine and no declared allergens, so it is suitable for vegetarians and vegans. The sea moss is concentrated into the capsule, so there is none of the taste of the raw gel. Sixty capsules per bottle. Two a day. Sea moss is a seaweed and iodine is native to it. Iodine carries an upper limit, so if you take other iodine-containing supplements, or you are managing a thyroid condition, speak to your GP before use. |
Irish Sea Moss CapsulesThe Glow Stack |
| Hydrolysed collagen peptides |
Type I and type III, the two most abundant collagen types, from bovine hide. Hydrolysed and fine-milled, unflavoured, no sweeteners, dissolving clean into hot coffee or a cold smoothie without clumping. Around thirty servings per 280 g tub. One scoop into the first drink of the day. |
Collagen Peptides |
| The rest of the biotin complex |
Thirteen actives sit alongside the biotin: vitamins A, C, D, E, B6 and B12, folate, pantothenic acid, iodine, zinc, PABA, collagen and silicon. It is a complex rather than a single nutrient. Sixty gummies per jar. Two a day, with or without food, and not more than the stated dose. The collagen in it is piscine, so the jar contains fish, and the gummies contain sugar. They also carry iodine and vitamin A, so check the totals if you take other supplements containing them. |
Biotin GummiesThe Glow Stack |
Every supplement in the range is made to order in a GMP-certified facility and batch-tested before it ships.
The scalp serum, under cosmetic wording
CROWNED Serum No.1 is a cosmetic. The GB nutrition and health claims register governs food and food supplements; a topical is read under cosmetic rules instead, where a claim is about appearance. One sentence is the ceiling for everything said about this bottle, and it is the same sentence in every market.
It conditions the skin and the hair it touches, and hair that is conditioned rather than dry and snapping tends to look fuller.
- What is in it
- Water and glycerin lead the formula, so it is a light serum rather than a heavy oil. Rosemary leaf extract sits near the top of the ingredient list, just after those two, with ginger root and liquorice root extract behind it, plus a chlorella and spirulina complex, vitamin C and vitamin E. Contains soybean and wheat germ extracts.
- How much
- 59 ml.
- How it is used
- A few drops onto a clean scalp once daily, massaged in for a minute or two. Leave it at least an hour or two before washing. It goes on before a bonnet or before you leave the house.
- How it is made
- In a GMP-certified facility, and batch-tested before it ships.
- Where it appears
- CROWNED Serum No.1The Glow Stack
This is a cosmetic, not a food supplement and not a medicine. For external use only, on the scalp. Keep it away from the eyes, and stop using it if your skin reacts. If you are pregnant, breastfeeding or being treated for a scalp condition, speak to your GP before use.
