Choosing protein and collagen
Nutri Tailor stocks protein powders and collagen chosen for the source and for short ingredient lists: grass-fed whey protein isolate, pea protein isolate for a vegan option, hydrolysed collagen peptides, and capsule formulas that supply the nutrients the body uses to make its own collagen. The table sets out what each is; the guide underneath compares the collagen sources.
Protein powders
| Product | What it is | Who tends to choose it |
|---|---|---|
| Unflavoured Whey Protein Powder | Grass-fed whey protein isolate, no flavouring | Smoothies and cooking; people who want nothing added |
| Vanilla, Chocolate, Strawberry, Banana, Chocolate Orange, Mint Chocolate and Salted Caramel Whey | The same grass-fed isolate, naturally flavoured | Shakes; the 196 g sizes for trying a flavour first |
| Unflavoured, Vanilla and Chocolate Pea Protein Powder | Pea protein isolate | Vegans, and anyone avoiding dairy |
Collagen
| Product | What it is | Who tends to choose it |
|---|---|---|
| Marine and Bovine Collagen Peptides Powder | Hydrolysed collagen from both sources | People who want collagen itself, unflavoured |
| Creamy Vanilla Collagen Powder | Hydrolysed collagen, flavoured | Collagen as a drink |
| Collagen Formula Capsules | Vitamin C with amino acids | Vitamin C contributes to normal collagen formation for the normal function of skin, cartilage and bones |

| Hyaluronic Acid Capsules, L-Proline Capsules, Hair, Skin and Nails Formula | Single nutrients and a formula | Alongside a collagen powder, or instead of one |
How to choose
Protein powders: whey isolate for the highest protein per serving and fast absorption, pea isolate where dairy is out; the comparison is here: Whey vs pea vs collagen: which protein powder should you buy? Collagen: the difference between marine and bovine is source and taste rather than evidence, and the guide sets out what the trials show: Marine vs bovine collagen: which should you buy? Protein contributes to the growth and maintenance of muscle mass and to the maintenance of normal bones; those are the authorised claims, and Nutri Tailor makes none beyond them for collagen itself.
