The part nobody puts on the pamphlet

The weight came off. So why does the mirror suddenly feel like a stranger?

Skin looking looser. Hair feeling finer. Nails that split, and joints that have gotten a little more vocal.

You’re proud of the change — you earned it. But nobody warned you that losing weight this quickly asks so much of the connective tissue underneath: the skin, hair, nails and joints that are made largely of collagen. After 50, your body already produces less of it, and a fast drop can bring that shift to the surface all at once. Renew answers with the exact amino-acid raw materials collagen is built from, so you can look in the mirror and still see yourself.

The science, simply

How Renew supports the skin, hair, nails & joints you keep.

01 · The change

Collagen declines with age

Collagen is the scaffolding under your skin and in your hair, nails and joints. Production naturally slows after 50, and rapid weight loss can make the shift more visible.

02 · The building blocks

Amino acids to build from

Hydrolyzed collagen delivers glycine, proline and hydroxyproline, the amino acids that provide the raw materials your body uses for skin, hair and nails. Studied at 2.5–10 g a day.

03 · Easy to keep

Unflavored & dissolves clean

Peptides are pre-broken-down for easy mixing. No taste, no grit. A half scoop stirred into your morning coffee, tea or water.

What the research shows

The proof, with sources.

19trials

A systematic review & meta-analysis of 19 randomized, placebo-controlled trials (1,125 people, 95% women) found ~90 days of hydrolyzed collagen supported skin elasticity and hydration and the appearance of smoother skin vs. placebo.

Meta-analysis, skin agingde Miranda et al., Int. J. Dermatol., 2021 · PMID 33742704
8wk

In a double-blind, placebo-controlled trial in women 35–55, 2.5–5 g of collagen peptides daily for 8 weeks produced a significant improvement in skin elasticity vs. placebo.

In a 24-week randomized, placebo-controlled trial, 10 g of collagen hydrolysate daily helped support joint comfort during activity vs. placebo.

Questions women ask us

Before you start

What does it taste like?

Nothing. Renew is unflavored and dissolves clean. Stir a scoop into hot or cold coffee, tea or water without changing the taste.

Will it help my skin, hair and nails?

Renew gives your body glycine, proline and hydroxyproline — the exact amino acids your skin, hair and nails are built from. In controlled trials, collagen peptides supported skin elasticity and hydration and the appearance of smoother skin. Think of it as handing your body the raw materials and letting it do what it does best. It supports the skin, hair and nails you already have; it isn’t a hair-growth drug. Most women give it the full 8–12 weeks the studies ran — and that’s exactly what the 60-day guarantee is there to protect.

Is it safe to take with my medication?

Renew is a dietary supplement made from grass-fed collagen — the same clean protein powder countless people already stir into their coffee — not a drug, and it makes no claim to treat or interact with any medication. As with anything new, run it by your doctor, then enjoy it with confidence.

How much should I take, and how long does a tub last?

A full level scoop is 20 g of hydrolyzed collagen peptides. Clinical studies used 2.5–10 g per day depending on the goal (skin, nails or joint comfort), so we suggest a 10 g half scoop daily: it sits at the top of the studied range and makes the 280 g tub last about a month. Prefer a full scoop? A tub is then a two-week supply.

What if it’s not for me?

Take it every morning for 60 days. If you don’t feel more like yourself, write us for a full refund.
