1. What is L-Carnitine Amp 3000mg 25ml Citroen and what does it do?
L-Carnitine Amp 3000mg 25ml Citroen is a single-serve L-carnitine pre-workout shot — 3000 mg L-carnitine per ampoule (25 ml, 12% concentrate), drinkable neat.
Per 25 ml ampoule: 3000 mg L-carnitine (12% concentrate). Flavour: lemon — fresh citrus flavour. 1 ampoule = 1 serving.
L-carnitine is a conditionally essential amino acid derivative that transports long-chain fatty acids across the inner mitochondrial membrane for β-oxidation — where fatty acids are converted into ATP. It is synthesised by the body itself from lysine and methionine (cofactors vit B6/C/niacin), but with sports activity, a vegan diet or advancing age, supplementation can be a useful addition.
2. Who is L-Carnitine Amp 3000mg 25ml Citroen suitable for?
For adults (18+) in a sports, recovery or energy metabolism context.
- Strength athletes and endurance athletes for recovery support
- Vegans and vegetarians (lower endogenous L-carnitine — smaller natural pool)
- Older people (lower endogenous synthesis with age)
- Anyone training in an energy deficit (extra substrate support)
- Athletes who want a single-serve pre-workout shot (lemon — fresh citrus flavour)
- Anyone who doesn't want to carry a bottle or open/close it
NOT suitable for: Children under 18 years, pregnancy and breast-feeding (insufficient safety data), chronic kidney disease (TMAO formation risk), untreated hyperthyroidism, epilepsy (theoretical trigger at higher doses).
3. What does L-carnitine do in my diet?
L-carnitine has NO EFSA-approved health claims — position it descriptively:
- L-carnitine transports long-chain fatty acids across the inner mitochondrial membrane for β-oxidation
- Conditionally essential — the body synthesises it from lysine + methionine (vit B6/C/niacin as cofactors)
- Highest concentrations in skeletal muscle and heart muscle (energy-rich tissues)
- Substrate function in energy-yielding fat metabolism
- Possible role in recovery after eccentric exercise (Volek 2002, Spiering 2008)
- No acute thermogenic effect — works at substrate level, not a stimulant
IMPORTANT for compliance: L-carnitine is on the EFSA on-hold list — there are no approved health claims for weight management or energy metabolism. L-carnitine supplementation does NOT cause weight reduction without an energy deficit; the transport mechanism works at substrate level — not as a stimulant or thermogenesis trigger. Suppstore positions L-carnitine as a substrate supplement within a sports and recovery context, not as a weight-loss product.
4. How do I take L-Carnitine Amp 3000mg 25ml Citroen?
1 ampoule (25 ml) drunk neat or diluted — 30-60 min pre-workout.
- Drink 1 ampoule neat (25 ml concentrate)
- Or dilute with 100-200 ml water for a milder flavour
- 30-60 min pre-workout for maximum substrate availability
- 1 ampoule per training day
- Single-serve format = no refrigeration needed
5. When is the best time to take L-Carnitine Amp 3000mg 25ml Citroen?
30-60 min before training or cardio for maximum substrate availability during β-oxidation.
On rest days: with breakfast for general energy metabolism support. If you use it twice a day: split between pre-workout and lunch.
6. Should I take L-Carnitine Amp 3000mg 25ml Citroen with or without food?
With a carbohydrate-containing meal for better absorption (insulin response increases L-carnitine uptake).
Stephens et al. (2007) showed that L-carnitine + ~80 g carbohydrates gave significantly higher muscle uptake than L-carnitine alone. For maximum muscle saturation: combine with a carbohydrate source or pre-workout shake.
7. How long does it take before I notice results?
Muscle L-carnitine saturation takes 12+ weeks with daily use.
Stephens et al. (2007): measured muscle uptake increases cumulatively over 12-24 weeks. Acute effects on performance are limited or non-existent.
8. Which form of L-carnitine does suppstore use and why?
Liquid L-carnitine concentrate in a single-serve ampoule (25 ml) — pre-workout shot format.
- Higher dose per serving (3000 mg) than the regular 100.000 Liquid (2000 mg)
- Single-serve = no opening/closing/refrigerating — handy for athletes
- Flavour variants: lemon — fresh citrus flavour
- Pre-workout shot format
9. What is the difference between L-carnitine tartrate, L-carnitine HCl and ALCAR?
Four main forms, different contexts:
- L-carnitine L-tartrate: most researched sports form — recovery focus (Volek 2002)
- L-carnitine HCl: direct form, comparable to tartrate in effect
- Liquid L-carnitine (from tartrate or HCl): fast absorption, drinkable
- Acetyl-L-Carnitine (ALCAR): crosses the blood-brain barrier — cognitive focus
- Propionyl-L-Carnitine: researched for cardiovascular use, less widely available
For general sports and recovery: L-tartrate. For cognitive use: ALCAR. For an energy deficit context: standard L-carnitine.
10. How much L-carnitine is in each dose?
Per 25 ml ampoule: 3000 mg L-carnitine (12% concentrate). Flavour: lemon — fresh citrus flavour. 1 ampoule = 1 serving.
Researched effective daily dose: 1-3 g L-carnitine. A 25 ml contains 1 ampoule.
11. What does the scientific research say?
L-carnitine research is broad but mixed for the sports context.
- Volek et al. (2002) — L-carnitine tartrate and recovery after squat training
- Spiering et al. (2008) — reduced post-exercise muscle damage markers
- Stephens et al. (2007) — carbohydrate protocol increases muscle L-carnitine uptake
- Wall et al. (2011) — chronic supplementation and endurance performance
- Pooyandjoo et al. (2016) — meta-analysis, small weight effect with diet (1-2 kg over 12+ weeks)
For compliance: the weight-effect meta-analysis (Pooyandjoo 2016) showed a SMALL effect only in combination with an energy-restricted diet — not with L-carnitine alone. Position it as a substrate function within energy metabolism, not as a weight-loss supplement.
12. Are there side effects?
Well tolerated up to 3 g/day in healthy adults.
- At high doses (>3 g): fishy body odour (trimethylamine excretion via skin/breath)
- Gastrointestinal complaints at high doses (nausea, diarrhoea)
- TMAO formation: gut bacteria convert L-carnitine into trimethylamine → liver → TMAO. Elevated TMAO is associated with cardiovascular risk in observational studies (Koeth 2013). Clinical significance still unclear, but a reason for moderate dosing.
- With kidney problems: accumulation risk
13. Who is better off not using L-Carnitine Amp 3000mg 25ml Citroen?
Do not use in case of:
- Children under 18 years
- Pregnancy and breast-feeding (insufficient safety data)
- Chronic kidney disease (TMAO formation risk)
- Untreated hyperthyroidism
- Epilepsy (theoretical trigger at higher doses)
14. Is L-Carnitine Amp 3000mg 25ml Citroen safe during pregnancy or breast-feeding?
Not recommended during pregnancy or breast-feeding without medical supervision.
L-carnitine is sometimes prescribed by doctors in specific obstetric contexts. Self-supplementation is inappropriate. Consult your midwife.
15. From what age can young people use L-Carnitine Amp 3000mg 25ml Citroen?
Not suitable for young people under 18 years.
16. Can I combine L-Carnitine Amp 3000mg 25ml Citroen with my medication?
Consult your doctor or pharmacist if you take medication.
- Anticoagulant medication (warfarin) — theoretically increased risk of bleeding at high doses
- Thyroid medication — L-carnitine may modify the T3 effect (only at high doses)
- Valproic acid (anti-epileptic) — L-carnitine may even be beneficial as a balance (medical consultation)
- Chemotherapy — only under oncological supervision
17. Can I combine L-Carnitine Amp 3000mg 25ml Citroen with other supplements?
Combines well with: creatine, BCAAs, whey/vegan protein, vitamin D3, omega-3, magnesium, B vitamins (cofactor).
Classic recovery stack: L-carnitine + omega-3 + magnesium. For cognitive use: ALCAR + alpha-GPC or choline.
Do not stack with: multiple L-carnitine products at the same time (>3 g/day plateau effect + TMAO risk).
18. Is L-Carnitine Amp 3000mg 25ml Citroen independently tested? Which certifications?
Yes, all batches are independently laboratory tested. CoA via coa@suppstore.com — EAN: 5999076204502.
- L-carnitine purity per batch (HPLC)
- Microbiology (total plate count, salmonella, E. coli)
- Heavy metals below EU limits
- Allergen monitoring
19. Is there testing for heavy metals and contaminants?
Yes — lead, cadmium, mercury, arsenic + microbiology + L-carnitine purity per batch. Under EU Regulation 1881/2006.
20. How do I store L-Carnitine Amp 3000mg 25ml Citroen and how long does it keep?
Store at 15-25°C in the original closed ampoule, in a dry place, protected from sunlight. Shelf life 18-24 months from production date. Single-serve = consume immediately after opening — do not store.
21. What if I forget a day?
Just carry on the next day — do not double the dose.
Consistency over weeks and months is more important than exact timing.
22. What about shipping, returns and warranty?
14-day statutory right of withdrawal. 90-day returns on unopened products. Opened ampoules cannot be returned for hygiene reasons. Support: support@suppstore.com.
