6 reasons the Glow Stack is the easiest hair, skin and bones routine
By the Vitastrong team · Updated November 2026 · 4.8/5 on Trustpilot
Hair, skin and bones each rely on different nutrients, and buying them one at a time adds up quickly. Marine collagen, biotin and vitamin D3+K2 on their own cost £83.96 on our site, before you even think about something to carry them in.
The Glow Stack puts all three in one box with a pink Vitastrong pouch, for £54.99 with free UK delivery. Here is what is inside, and why it works as a routine.
1Marine collagen with vitamin C
2,000 mg of marine collagen per daily dose, with hyaluronic acid and vitamin C. Vitamin C contributes to normal collagen formation for the normal function of the skin.
2Biotin for hair and skin
Biotin contributes to the maintenance of normal hair and skin. Our Biotin Complex adds zinc and selenium, which contribute to the maintenance of normal hair and nails.
3Vitamin D3+K2 for your bones
2,000 IU of vitamin D3 with 100 µg of vitamin K2 (MK-7). Vitamins D and K contribute to the maintenance of normal bones. In the UK winter, vitamin D is the one the NHS suggests everyone should consider.
4Big packs, fewer reorders
180 collagen tablets, 450 biotin tablets and 365 tablets of D3+K2. Check each label for the daily dose.
5A routine you can carry
The pink Vitastrong pouch keeps your daily doses together, at home, at work or away for the weekend.
