L-Cysteine 99% Powder

Capsule (with meal): 300–600 mg once or twice daily for a tidy, repeatable serving.

Water Mix: Stir 300–600 mg into 200–300 ml water; add citrus/ginger flavour to soften sulphur notes.

Pre-Movement: 500–1,000 mg in water 30–45 minutes before activity; pair with fluids and a normal meal pattern.

Gummies/Functional Foods: Target 100–300 mg per serving; pilot flavour, water activity and odour management.

Stack Idea: Anchor cysteine first; after a week consider adding electrolytes or a protein habit—one change at a time while tracking comfort.

Routine-Ready: Single amino acid that fits clean, repeatable daily habits.

Neutral & Versatile: Mild taste and good solubility suit sticks, beverages, capsules and gummies.

Compact & Predictable: ≥99% purity simplifies mg-math and label uniformity.

Format-Friendly: Works across capsules, sachets, drinks and gummies without heavy flavour load.

Serving Size: 1 scoop or multiple capsules (≈ 300–600 mg powder)

Ingredients: L-Cysteine (≥99%)

Does Not Contain: Caffeine, artificial colours, artificial flavours

Allergen Information: Vegan; gluten-free; dairy-free. Sulfur-containing amino acid—consider total protein goals if tracking intake; consult a professional if pregnant, nursing, have a history of cystine stones or are on medications.

Usage Recommendation: Take 300–600 mg once or twice daily dissolved in water or in capsules. If stacking with other actives, add one change at a time and space ~90 minutes from medications as a routine practice.

Storage Advice: Store cool, dry & dark. Keep tightly sealed away from moisture and direct sunlight.

Keep Away From Children

Q: How do I add L-cysteine to a simple daily routine without changing my whole diet?

A: Keep the routine minimal and consistent so evaluation stays honest. Choose one moment you rarely miss—many prefer with breakfast or pre-movement—mix 300–600 mg in water (or use capsules if you dislike sulphur notes), and hold other variables steady: a balanced plate, unhurried eating, regular steps and steady sleep. The goal is a small, durable cue instead of occasional large doses. Run the same serving for two to four weeks, record adherence and perceived ease, and then adjust gradually. Consistency beats micro-tweaks when you want a habit that survives travel and busy days.

Claim-strength scale – High = multiple human studies; Moderate = a few trials; Emerging = early lab data.

Q: Capsules, sticks or gummies—what’s most practical for L-cysteine day to day?

A: Pick the format you’ll repeat effortlessly. Capsules avoid taste and make 300–600 mg precise. Water sticks tie the habit to hydration; add citrus for a cleaner finish. Gummies are convenient but need careful flavour systems and water-activity control. Whatever you choose, keep the per-day total and timing identical during your trial, document variables like pH and fill temperature, and avoid switching formats mid-evaluation so your read on usefulness stays clear and your SOPs remain simple to scale.

Q: Any formulation tips to manage sulphur odour or taste?

A: Decide the per-serve target first, then layer bright flavours (citrus/ginger), use quick dissolution in cool water, and minimise hold time at warm temps. In gummies, target 100–300 mg per unit, pre-disperse into warm syrup, and pair with acids plus a small amount of natural flavour masker. Store pilots cool and dry, and re-taste at 1–2 weeks; cysteine’s aroma can emerge over time, so documenting pH, mix time and fill temp helps keep sensory and label uniformity across runs.

Q: Any safety notes I should consider before adding cysteine?

A: Start low and assess comfort, especially if pregnant or nursing, or if you have a history of cystine kidney stones or are on specialised regimens—seek professional guidance as needed. Keep a 90-minute buffer from medications as a routine practice. If you notice digestive or taste fatigue, reduce the amount and increase fluids. A simple, steady routine—fixed serving, fixed time—gives you a cleaner read on whether cysteine earns a permanent spot in your day-to-day plan.
