The science of creatine + collagen for women

Three actives. Every dose disclosed.

What is in each scoop, why it is there, and at what amount.

One scoop · 9.3 g
5 g creatine. 2 g collagen. Every day.
5,000 mg

Creatine Monohydrate

The most-studied form of creatine. Micronized for a clean mix. Creatine helps cells regenerate ATP — the energy currency used by muscle and brain tissue alike. Research on daily supplementation covers strength, power output, and cognitive performance.*

2,000 mg

Hydrolyzed Marine Collagen Peptides (Type I)

Sourced from fish, hydrolyzed to a low molecular weight for absorption. Type I is the collagen most abundant in skin, hair, and nails.*

1,000 mg

BCAA 2:1:1

L-Leucine, L-Isoleucine and L-Valine in the standard 2:1:1 ratio, the essential amino acids found in protein-rich foods.*

50 mg

Hibiscus Flower Extract

A natural source of polyphenols, used alongside beet root powder for colour — no artificial dyes.*

Why these amounts

The dose, explained.

5 g

Creatine monohydrate

The International Society of Sports Nutrition recommends 3–5 g a day to maintain muscle creatine stores. Taken daily without a loading phase, stores rise gradually over about three to four weeks.

2 g

Collagen peptides

Studies of oral collagen peptides have used anywhere from under 1 g to about 12 g a day. We use 2 g of low-molecular-weight Type I peptides so creatine and collagen fit into one 9.3 g scoop.

Artificial dyes

The coral-pink color comes from hibiscus extract and beet root powder, an FDA-listed color exempt from certification. Sweetened with stevia leaf extract (Reb-M). No sugar, no artificial flavors or colors.

Creatine for women

What the research says.

  • Creatine monohydrate is one of the most studied supplements. The International Society of Sports Nutrition considers it safe for healthy people at recommended doses. Kreider et al., 2017
  • A review of 29 trials in women found no increase in side effects and no significant weight gain compared with placebo. de Guingand et al., 2020
  • A 2024 meta-analysis of 16 trials linked creatine with better memory, and the effect on processing speed was larger in women. Xu et al., 2024
  • In active women, creatine paired with training showed small benefits for performance and body composition. Lin et al., 2026
Collagen peptides

A 2023 meta-analysis of 26 randomized trials found that oral collagen improved skin hydration and elasticity compared with placebo. Daily doses in those trials ranged from under 1 g to 12 g, and results varied between products.*

Testing and manufacturing

  • Manufactured in a cGMP-registered facility in the United States
  • Third-party tested for identity, potency and contaminants
  • Heavy metals tested by ICP-MS
  • No proprietary blends — every active is disclosed with its amount
