What is in beauty and skin support?

Products here centre on collagen peptides, biotin, silica, zinc, vitamin C and hyaluronic acid. Hair, skin and nails are all largely protein structures, so the general logic is supplying the building blocks and the cofactors involved in making them.

A realistic note on what to expect. Where a genuine deficiency exists, in iron, zinc or protein most commonly, correcting it can make a visible difference, and hair in particular responds to iron status. Where intake is already adequate, adding more of these nutrients generally does less than the packaging implies. Collagen peptides have the most direct research behind them in this space, and even there effects are gradual and modest.

How it is usually used

Daily, and judged over at least eight to twelve weeks, because hair and nails grow slowly and nothing in this category acts quickly. Collagen powders are generally unflavoured and dissolve into coffee or a smoothie. Supplements are not a substitute for medical advice. If you are pregnant or breastfeeding, take prescription medication, or are managing a health condition, check with your doctor or pharmacist before starting something new.

Frequently asked questions

Does collagen improve skin?

Several trials on collagen peptides report modest improvements in skin hydration and elasticity over eight to twelve weeks. The effects are real but measured, not dramatic, and they depend on taking it consistently. Anything promising a visible change in a fortnight is overstating it.

Is biotin worth taking for hair?

Biotin deficiency genuinely causes hair and nail problems, but actual deficiency is rare in people eating a varied diet. In those who are not deficient, the evidence that extra biotin improves hair is weak. Worth knowing: high dose biotin can interfere with some blood tests, including thyroid and cardiac tests, so tell your doctor if you take it.

How long until I see a difference?

Hair grows roughly a centimetre a month and nails more slowly still, so three months is the minimum sensible window for judging anything in this category. Skin studies typically run eight to twelve weeks.

What causes hair loss that supplements will not fix?

A great deal of it. Genetic pattern hair loss, thyroid conditions, hormonal changes, significant stress and iron deficiency all have different causes and different treatments. If hair loss is sudden, patchy or significant, see a doctor rather than working through supplements.

Do I need marine collagen specifically for skin?

Marine collagen is mostly type I, which is the predominant collagen in skin, and that is the basis of the marketing. In practice bovine collagen supplies types I and III and performs comparably in studies. Choose on price, dietary preference and allergy rather than expecting a large difference.
