We love questions

Which Keeper product is best for skin, hair and nails?

Body Boost, with 5 g marine collagen, 150 mg hyaluronic acid, 250 mg vitamin C, biotin and zinc per serve.

What are the best supplements for skin health?

Skin focused supplements commonly contain nutrients involved in collagen formation, skin structure and hydration. These include collagen, vitamin C, hyaluronic acid, zinc and biotin. Body Boost combines 5 g marine collagen, 250 mg vitamin C, 150 mg hyaluronic acid, 20 mg zinc as zinc picolinate and 1,000 mcg biotin.

Does marine collagen help support skin health?

Collagen is a major structural protein in the skin, and collagen production changes with age. Marine collagen is commonly used in beauty supplements as a source of collagen peptides. Body Boost provides 5 g marine collagen per serve, alongside vitamin C, hyaluronic acid, zinc as zinc picolinate and biotin.

Why are vitamin C and collagen often taken together?

Vitamin C contributes to normal collagen formation, making it a natural complement to collagen supplementation. Rather than providing collagen alone, Body Boost combines 5 g marine collagen with 250 mg vitamin C, alongside hyaluronic acid, zinc as zinc picolinate and biotin.

What does hyaluronic acid do for skin?

Hyaluronic acid occurs naturally throughout the body, including in the skin, and has a strong capacity to bind water. This is why it is commonly associated with skin hydration. Body Boost provides 150 mg hyaluronic acid alongside marine collagen and vitamin C as part of its broader skin focused formula.

What is the gut skin connection?

The relationship between the gut microbiome and skin is often referred to as the gut skin axis. The two systems can interact through microbial, metabolic and immune pathways. Good Gut supports the gut side of this relationship with Akkermansia muciniphila, Bacillus coagulans, prebiotic inulin and pectin, colostrum and L-glutamine as part of its broader microbiome formula.

Is marine collagen better than bovine collagen?

Both are sources of collagen peptides. Marine collagen comes from fish and bovine collagen from cattle, and many people choose marine collagen if they prefer to avoid beef derived products. Body Boost uses 5 g marine collagen per serve. Because it comes from fish, it is not suitable for people with a fish allergy.

How is Body Boost different from a regular collagen supplement?

Most collagen supplements focus on skin alone. Body Boost combines 5 g marine collagen with 5 g creatine, HMB, hyaluronic acid, D-ribose, biotin and zinc to support skin, hair, nails and muscle strength in one daily serve.

How long before I notice results from Body Boost?

Individual responses vary. Some people notice changes in skin hydration within a few weeks, while changes in skin, hair, nails and muscle tone build over 8 to 12 weeks of consistent daily use.

Is Body Boost vegan or vegetarian?

No. Body Boost contains marine collagen sourced from fish, so it is not suitable for vegans or vegetarians.
