Beauty

Beauty supplements are not one ingredient. On this page you will find collagen in powders and capsules, biotin, zinc, selenium, vitamin C, silica and hyaluronic acid, plus complete formulas that combine several of them. What they share is a link with the tissue you can see: skin, hair and nails.

European rules keep the wording tight, and that is useful when you compare labels. Biotin contributes to the maintenance of normal hair and skin. Zinc contributes to the maintenance of normal skin, hair and nails. Selenium contributes to the maintenance of normal hair and nails. Vitamin C contributes to normal collagen formation for the normal function of the skin. Copper contributes to normal hair pigmentation. If a product promises a glow instead of naming a nutrient, it is selling a story. Our page for hair, skin and nails groups products by that same logic.

Form and dose decide more than the front of the pack

Collagen has no approved health claim in Europe, so we describe it plainly instead. Hydrolysed peptides are collagen cut into small fragments, which makes the powder dissolve easily. Marine collagen delivers mainly type I, the type found in skin. Bovine collagen gives type I and III. Research that reports any change uses roughly 2.5 to 10 grams a day, so a single 500 mg capsule will not get you there. Powders reach those amounts at a lower cost per gram, which is why most of our collagen range lists grams per serving.

Biotin is where dosing gets strange. Products of 5,000 or 10,000 mcg are common, yet extra biotin only helps if your intake was low, and for most people it is not. High intakes can also distort some laboratory blood tests, including thyroid tests, so tell your doctor if you take it before blood work. Zinc is the opposite case: small amounts, but form matters. Bisglycinate and citrate are absorbed better than oxide and sit more comfortably on an empty stomach.

How we choose what goes in this collection

We judge three things: the form, the dose and whether the combination makes sense. Zinc, selenium, biotin and vitamin C together is coherent, because each one has its own approved role. Twenty ingredients at token amounts is not, so we leave those out. We buy directly from the brands, which means what arrives is authentic, and every product passes our compliance team before it goes live. We test products ourselves and independent labs spot-check batches. We would rather explain a higher price per serving than hide a low dose: see how we select brands and products.

Who this suits, and how long to give it

These products fit you if your diet is uneven, if you eat little animal protein, or if colouring, heat styling or constant nail polish have you looking for support from the inside. They are a top-up, not a replacement for food, sleep and sun protection.

Timing is the honest part. Nails grow around 3 mm a month and scalp hair around 1 cm, so give any product eight to twelve weeks of daily use before you judge it. Skin comfort and hydration often shift sooner. If firmness over the longer term is your focus, our anti-ageing selection sits next to this one.
