Why LYL premiumC, not typical Vitamin C?

Built for premium daily performance — acid-free comfort, sustained release delivery, and a clinically-smart formula with bioflavonoids.

LYL premiumC (LYLsmart™)

Acid-free vitamin C

Sustained release (8-hour effect)

Premium formula upgrade

High absorption positioning

Designed for sensitive users

Clean-label & plant-based

Typical Vitamin C (standard ascorbic acid)

Often acidic — may irritate sensitive stomachs

Short-lived peak — “fast in, fast out” experience

Usually without bioflavonoids

Less “daily comfort” focus in formula design

Can be harder to stay consistent with long-term

Many products are just “C only”

Why we use blister-sealed protection

Because premium Vitamin C deserves clean, stable, and consistent daily potency.

1

Protected from air, moisture & light

Each capsule is individually sealed — helping preserve freshness and formula integrity until the moment you take it.

2

Reliable from first capsule to last

No repeated exposure from opening a bottle — every dose stays consistent throughout the full pack.

3

Clean, travel-ready & hygienic

Pop one capsule anytime, anywhere — no contamination risk, no mess, perfect for daily routines on the go.

Gentle on stomach

No stomach upset, easy to take daily

What makes LYL premiumC different from regular vitamin C?

LYL premiumC is a next-generation, acid-free vitamin C formula with high absorption, designed to be gentle on the stomach and supported by a premium bioflavonoid complex for enhanced daily support.

Is it gentle on the stomach?

Yes. premiumC uses an acid-free (alkaline) form of vitamin C, making it a smart choice for people who experience discomfort from traditional ascorbic acid.

What do bioflavonoids add to the formula?

premiumC is enriched with hesperidin, quercetin, and rutin — valuable plant compounds that complement vitamin C with extra antioxidant support, giving the formula a true “premium” profile.

Can I take it for immune support?

Yes. Vitamin C helps support the normal function of the immune system and helps protect cells from oxidative stress, making premiumC ideal for everyday use — especially during challenging seasons.

Does vitamin C improve iron absorption?

Yes. Vitamin C enhances iron absorption, which makes premiumC a great addition to routines where maintaining healthy iron levels is important.

How do I take LYL premiumC — 1 or 2 capsules per day?

1 capsule daily = maintenance support
2 capsules daily = increased vitamin C needs (e.g., stress, seasonal demands, active lifestyle)

How long does delivery take?

Orders are typically delivered within 2–4 business days when shipped with our international express partners such as FedEx, DHL or UPS.

During peak periods (holidays, promotions), small delays are possible.

Is shipping free?

We offer free shipping above a certain order value (shown at checkout).

Can I track my order?

Absolutely. Once your order is shipped, you’ll receive a tracking link by email from the carrier (FedEx, DHL, UPS or regional partners), allowing you to follow your shipment in real time.

Do you ship internationally?

Yes — we ship to all EU countries and a wide range of international destinations.
