Overview
Hydro Q10 Plus Carnitine Capsule is a combination dietary supplement that provides two nutrients in one capsule: coenzyme Q10 (CoQ10) and L-carnitine. It is taken as a single capsule once a day, and the pack available on DoctorOnCall contains 30 capsules, a one-month supply. The exact amount of each ingredient per capsule is stated on the product label, so please check the pack for the full composition.
Coenzyme Q10 is a fat-soluble, vitamin-like compound produced by the body and found in foods such as meat and fish. It plays a part in the mitochondrial reactions that generate cellular energy and acts as an antioxidant within cell membranes. L-carnitine is a nutrient derived from the amino acids lysine and methionine; it transports long-chain fatty acids into the mitochondria so they can be used as fuel. Healthy adults normally make enough L-carnitine themselves and obtain more from red meat and dairy foods, but intake may be lower in people who eat little or no animal produce.
Because both coenzyme Q10 and L-carnitine are involved in how cells handle fuel for energy, they are often combined in a single formulation for adults who want convenient daily supplementation. This product is not a slimming or weight-loss product, and it does not replace a balanced diet, regular physical activity or medicines prescribed by your doctor. People taking blood thinners, thyroid medicine, blood pressure or diabetes medicines should seek advice before using it.
Directions for Use
Swallow one capsule whole with a glass of water after a meal. Taking it after food helps the absorption of the fat-soluble coenzyme Q10 and may reduce the chance of stomach upset from L-carnitine. Do not open or chew the capsule, and take it at a regular time each day, preferably earlier in the day if you notice any effect on sleep.
Dosage
Adults: 1 capsule once daily after a meal, or as directed by your doctor or pharmacist. Do not exceed the recommended dose on the product label, and do not combine with other coenzyme Q10 or L-carnitine products unless advised. If you miss a dose, take the next capsule at your usual time without doubling up. Not intended for children unless advised by a doctor.
Storage Instructions
Store in a cool, dry place away from direct sunlight, heat and moisture, and keep the container or blister pack tightly closed after each use. Do not store in the bathroom or in a hot car. Keep out of reach and sight of children, and follow any specific storage instructions shown on the product label.
Side Effects
- Common: Mild digestive discomfort such as nausea, upset stomach, heartburn, loss of appetite or diarrhoea; taking the capsule with a meal may help.
- Common: Headache or dizziness in some people, usually mild and temporary.
- Less common: Difficulty sleeping (insomnia) has been reported with coenzyme Q10; if this happens, taking the capsule earlier in the day may help.
- Less common: L-carnitine may cause nausea, vomiting, abdominal cramps, diarrhoea or a fishy body odour, mainly at higher intakes.
- Serious: Allergic reactions such as rash, itching, swelling of the face, lips or tongue, or difficulty breathing are rare – stop taking the product and seek urgent medical attention.
- Serious: Unusual bruising or bleeding, or a change in blood test results (INR) in people taking warfarin – contact your doctor promptly.
Contraindications
- Do not take if you are allergic to coenzyme Q10 or to any other ingredient in the capsule, including L-carnitine and the capsule excipients listed on the label.
- Not recommended for children unless advised by a doctor, as the product is formulated for adults.
- Not recommended during pregnancy or breastfeeding unless advised by a doctor, because safety data in these groups are limited.
- People taking warfarin or other blood-thinning medicines should not start this product without first speaking to their doctor.
- People with a seizure disorder (epilepsy) or with severe kidney disease should not take L-carnitine-containing products unless their doctor has advised it.
Drug / Food Interactions
- Warfarin: Coenzyme Q10 may interact with warfarin and has been reported to reduce its blood-thinning effect; your doctor may need to monitor your INR more closely if you start or stop this product.
- Blood pressure medicines (antihypertensives): Coenzyme Q10 may add to the blood-pressure-lowering effect of these medicines; monitor your blood pressure and tell your doctor if you feel light-headed or dizzy.
- Insulin and other diabetes medicines: Coenzyme Q10 may interact with insulin and could affect blood glucose levels; check your blood sugar regularly and speak to your doctor before starting.
- Chemotherapy: Antioxidant supplements such as coenzyme Q10 may not be compatible with some cancer treatments; always consult your oncologist before taking this product during chemotherapy or radiotherapy.
- L-carnitine and anticoagulants: L-carnitine has been reported to increase the effect of coumarin anticoagulants such as warfarin and acenocoumarol, so medical supervision is especially important.
- L-carnitine and thyroid hormone: L-carnitine may reduce the action of thyroid hormone; people taking levothyroxine should consult their doctor first.
- Food: Coenzyme Q10 is fat-soluble, so it is best absorbed when taken with a meal that contains some fat.
- Other supplements: Check the labels of multivitamins and other products you take to avoid duplicating coenzyme Q10 intake.

Frequently Asked Questions
Each capsule combines coenzyme Q10 and L-carnitine. The exact amount of each ingredient per capsule, together with the other ingredients, is printed on the product label, so please refer to the pack for the full composition.
No. L-carnitine helps transport fatty acids into cells for energy production, but this product is a nutritional supplement and should not be relied on for weight loss. Weight management depends on a balanced diet, physical activity and, where needed, advice from a doctor.
Swallow one capsule with water after a meal, once a day. Taking it after food supports absorption of coenzyme Q10 and can make stomach upset from L-carnitine less likely.
L-carnitine may reduce the action of thyroid hormone and has been reported to increase the effect of coumarin anticoagulants, while coenzyme Q10 may reduce the effect of warfarin. Because of these opposing effects, speak to your doctor before starting so your treatment can be monitored.
People with a seizure disorder or severe kidney disease should not use L-carnitine supplements unless their doctor advises it. It is also not recommended during pregnancy, breastfeeding or for children without medical advice, as safety data are limited.
Gut bacteria break down some L-carnitine into compounds that can produce a fishy odour, which is more likely at higher intakes. If this happens, or if you have ongoing nausea or diarrhoea, stop the product and speak to a pharmacist or doctor.
