Vitamin injections at CoLaz clinics

We offer three single-nutrient injections. Vitamin D, given as cholecalciferol, supports bone health, immune function and mood, and is the most commonly booked option through autumn and winter in the UK. Biotin, vitamin B7, supports the keratin structure of hair, skin and nails and is popular as a beauty-from-within booster alongside topical care. Vitamin C, ascorbic acid, is a strong antioxidant that supports immune function, collagen synthesis and post-illness recovery. Each is priced at £55 per single injection or £289 for a course of six, working out to £48 per session. The right vitamin for you is agreed at your free consultation.

Oral vitamins have to survive the stomach, the liver and the gut wall before any of what is left reaches the bloodstream, and absorption rates vary widely depending on the vitamin, the formulation and the patient. Vitamin D in particular is fat-soluble and depends on dietary fat at the time of dosing; biotin and vitamin C are water-soluble and depend on consistent daily intake. An intramuscular injection bypasses the digestive tract and delivers a measured dose straight into the bloodstream over the following hours, which gives a predictable rise in circulating levels and is particularly useful for patients with absorption issues, restrictive diets or busy schedules that disrupt daily supplementation.

The answer depends on your goal and your baseline. Vitamin D is the right call for low mood through the darker months, for fatigue with no obvious cause, and for patients who spend little time outdoors. Biotin is the right call when hair shedding, brittle nails or dull skin are the main concerns, alongside a balanced diet and a proper haircare routine. Vitamin C is the right call for immune support around travel or a busy work period, for post-illness recovery, and for patients wanting an antioxidant top-up. Many patients book one type for a course of six, then switch to another for the next course; the plan is agreed at consultation and confirmed in writing.

Most patients notice a difference within a few days to two weeks, depending on the vitamin and how depleted you were at the start. Vitamin D builds up over two to four weeks because the body needs time to convert and store it. Biotin effects on hair and nail growth take six to twelve weeks to be visible because new growth has to emerge from the follicle. Vitamin C effects on energy and immune support are usually felt within days. A single shot lasts four to eight weeks for most patients, with maintenance typically every four to six weeks once an initial course is complete.

The needle used is short and fine, and most patients describe the sensation as a quick pinch or a sharp pressure that lasts about a second. The injection itself takes around ten seconds. Mild soreness at the site for a day or two is normal and feels similar to the morning after a tetanus or flu jab. There is no other downtime: you can drive home and return to work, the gym or normal activities the same day, avoiding only intense upper-body exercise on the treated arm for a few hours.

Every injection at CoLaz is given by a qualified nurse or doctor, never a non-medical therapist. We run a brief health check before the first session and review your medical history, allergies and current medication in detail at the free consultation. We do not treat patients who are pregnant or breastfeeding without GP sign-off, patients with a known allergy to any component of the formulation, patients with high blood calcium for vitamin D, or patients with significant kidney disease. There is a £50 consultation fee, which is redeemable against any injection you book.

Each single vitamin injection, whether vitamin D, biotin or vitamin C, is £55. A course of six of any one type is £289, which works out to £48 per session. There is a £50 consultation fee with a qualified nurse or doctor, redeemable against any injection you book. Pricing is confirmed in writing at your free consultation, with no upsells in the treatment room.
