Frequently asked questions

Which nutrients are linked to normal bone and muscle function?

Under EU-authorised health claims, calcium, vitamin D, vitamin K, magnesium, manganese, zinc and protein all contribute to the maintenance of normal bones. Magnesium, calcium, vitamin D, potassium and protein contribute to normal muscle function. Vitamin C contributes to normal collagen formation for normal cartilage function.

What is the difference between marine and bovine collagen?

Marine collagen is fish-derived and mainly type I, the type dominant in skin. Bovine collagen supplies types I and III. Type II collagen, associated with cartilage, usually comes from chicken sources. Marine collagen is a fish allergen; check the label if you have allergies or follow a specific diet.

Do collagen supplements actually reach joints and skin?

Collagen is digested into peptides and amino acids rather than absorbed intact, then used wherever the body directs. Research on hydrolysed collagen peptides for skin elasticity and joint comfort is mixed but growing, with most trials running 8 to 12 weeks. Vitamin C is required for the body's own collagen synthesis, which is why many products include it.

Magnesium for muscle cramp — which form?

Bisglycinate and citrate are the best-absorbed common forms; oxide is cheapest but poorly absorbed and most likely to loosen stools. Magnesium contributes to normal muscle function under EU-authorised claims, though cramp has many causes including hydration and electrolyte balance more broadly.

How much protein do I need if I train?

General guidance for people doing regular resistance training is roughly 1.6 to 2.2 g of protein per kilogram of bodyweight daily, from food and supplements combined. Protein powder is a convenience, not a requirement — it just makes the total easier to reach.
