Alpha Lipoic Acid + Chromium Polynicotinate + Vitamin B7 (Biotin) + Zinc (Elemental Zinc) is a metabolic and antioxidant supplement that contains alpha lipoic acid (ALA), a fatty-acid antioxidant, chromium polynicotinate, a form of trivalent chromium investigated in carbohydrate metabolism, vitamin B7 (biotin), a coenzyme involved in fatty acid synthesis and gluconeogenesis, and zinc, a trace mineral. The combination is used as nutritional support in conditions associated with oxidative stress, metabolic syndrome features, and skin, hair, and nail health, under medical guidance.

Oxidative stress and impaired carbohydrate handling are common threads in many metabolic conditions, including type 2 diabetes, metabolic syndrome, and chronic skin and hair complaints. This supplement combines four components that act on these pathways through complementary mechanisms.

Alpha lipoic acid (ALA) is a short-chain fatty acid containing two sulfur atoms in a dithiolane ring and is both fat- and water-soluble. It is synthesised in small amounts in the body and obtained in trace amounts from foods. Clinical research has investigated alpha lipoic acid for its potential to reduce neuropathic symptoms such as burning, tingling, and pain in diabetic peripheral neuropathy, and for its ability to support antioxidant defences by increasing glutathione levels, though evidence on clinical benefit remains mixed.

Chromium polynicotinate is a form of trivalent chromium bound to niacin, intended to improve absorption compared with some other chromium salts. Trivalent chromium has been studied for its role in supporting insulin action on glucose uptake, although clinical evidence for benefits in diabetes is mixed and modest.

Biotin (vitamin B7) is a water-soluble B vitamin that acts as a coenzyme for carboxylase enzymes involved in fatty acid synthesis, amino acid metabolism, and gluconeogenesis. Biotin deficiency, although uncommon in healthy adults, can cause hair thinning, brittle nails, dermatitis, and neurological symptoms — and biotin is widely included in supplements aimed at skin, hair, and nail health. One important practical consideration, described in a clinical study on biotin and laboratory assay interference, is that high-dose biotin supplementation can significantly distort the results of several common immunoassays, including thyroid function tests and cardiac troponin.

Zinc is a trace mineral required for the catalytic, structural, and regulatory roles of more than 300 enzymes. It is essential for insulin synthesis, storage, and release; for antioxidant enzyme function (such as Cu/Zn superoxide dismutase); for taste and smell; and for wound healing. Together, the four components target oxidative defence, glucose metabolism, and tissue maintenance in a single supplement.

• To address combined chromium, biotin, and zinc inadequacy in adults at risk.

• As a nutritional supplement supporting skin, hair, and nail health, upon medical consultation.

• Alpha lipoic acid is both fat- and water-soluble and acts as a broad-spectrum antioxidant.

• Chromium has been investigated for its role in supporting insulin action on glucose handling.

• Biotin is essential for fatty acid synthesis, gluconeogenesis, and maintenance of skin, hair, and nail tissue.

• Zinc supports antioxidant enzyme activity, insulin handling, and tissue repair.

• Convenient single supplement combining four complementary nutrients.

Common

• Mild gastrointestinal upset (nausea, stomach discomfort)
• Metallic taste
• Headache
• Acne or skin rash (occasionally with biotin)

Uncommon

• Loose stools
• Dizziness
• Mild itching

Serious side effects requiring immediate attention

• Severe allergic reaction
• Hypoglycaemia (high blood sugar levels) in people on insulin or sulfonylureas (more likely with high-dose ALA or chromium)
• Significant interference with laboratory test results from high-dose biotin (including thyroid function tests, troponin assays, and hormone assays)
• Symptoms of copper deficiency with prolonged high-dose zinc, which may present as anaemia or neurological symptoms

Take Alpha Lipoic Acid + Chromium Polynicotinate + Vitamin B7 (Biotin) + Zinc (Elemental Zinc) orally as prescribed, generally with or just after a meal to reduce gastrointestinal upset, although alpha lipoic acid is sometimes recommended on an empty stomach for better absorption — follow your doctor's specific guidance. Swallow whole with a glass of water. Do not exceed the prescribed dose. If you take medicines for diabetes, monitor blood glucose carefully, as components in this supplement may lower blood sugar. If you are scheduled for any laboratory tests, particularly thyroid function or cardiac troponin assays, tell your doctor and the lab that you are taking biotin — high-dose biotin can significantly interfere with results.

Alpha lipoic acid acts as an antioxidant by directly scavenging reactive oxygen and nitrogen species and by regenerating other antioxidants such as vitamin C, vitamin E, and glutathione. It also serves as a cofactor for mitochondrial enzymes involved in energy production (such as pyruvate dehydrogenase). In clinical research, ALA has been investigated for its effects on nerve function in diabetic peripheral neuropathy and on markers of oxidative stress.

Trivalent chromium is thought to support the action of insulin on its target cells, helping muscle and fat cells take up glucose from the blood. The exact molecular mechanism is still under investigation, with proposed roles involving a low-molecular-weight chromium-binding substance (LMWCr or 'chromodulin').

Biotin functions as a coenzyme for carboxylase enzymes, including acetyl-CoA carboxylase (fatty acid synthesis), pyruvate carboxylase (gluconeogenesis), and propionyl-CoA carboxylase (amino acid and odd-chain fatty acid metabolism). These reactions are central to energy metabolism and to the maintenance of skin, hair, and nail tissue.

Zinc is incorporated into more than 300 enzymes as a structural or catalytic component. In carbohydrate metabolism, zinc is essential for the synthesis, storage, and crystallisation of insulin in pancreatic beta cells. In antioxidant defence, zinc is part of Cu/Zn superoxide dismutase, an important enzyme that neutralises superoxide radicals. Zinc also supports immune function, taste and smell, wound healing, and the integrity of skin and hair.

• Meals (BENEFICIAL): Reduce gastrointestinal upset. Though ALA absorption is sometimes higher on an empty stomach. Follow your doctor's advice.

• Tea and coffee (CAUTION): Tannins may reduce zinc absorption. Separate the two by an hour.

• High-phytate foods (CAUTION): May reduce zinc absorption.

• Alcohol (CAUTION): Affects glucose handling and may worsen oxidative stress.

• Insulin and sulfonylureas (SEVERE): Additive hypoglycaemic effect; monitor glucose.

• Levothyroxine (CAUTION): Zinc can reduce absorption. Separate the two doses by at least 4 hours.

• Tetracyclines and fluoroquinolones (SEVERE): Zinc binds these antibiotics. Separate the two by at least 2 to 4 hours.

• Penicillamine (SEVERE): Zinc reduces absorption. Separate the doses by several hours.

• Iron supplements (CAUTION): Zinc competes with iron absorption. Separate the doses by 2 hours.

• Anticoagulants (CAUTION): ALA may have antiplatelet effects. Inform your doctor if you take blood thinners.

• Anticonvulsants (CAUTION): Some anticonvulsants can lower biotin levels and may interact with biotin supplementation.

• Diabetes on glucose-lowering medication (CAUTION): Risk of hypoglycaemia (low blood sugar levels). It is advised to monitor blood sugar levels regularly.

• Wilson's disease (CONSULT YOUR DOCTOR): Zinc supplementation alters copper handling and should be coordinated with treatment.

• Thyroid disease (CAUTION): High-dose biotin can significantly interfere with laboratory thyroid function tests; stop biotin for several days before testing if instructed.

• Chronic kidney disease (CAUTION): Some chromium and zinc handling may be affected.

• Iron overload disorders (CAUTION): Zinc supplementation interacts with iron handling.

Overdosing on Alpha Lipoic Acid + Chromium Polynicotinate + Vitamin B7 (Biotin) + Zinc (Elemental Zinc) can cause gastrointestinal upset, hypoglycaemia (low blood sugar levels), especially in those on diabetes medication, copper deficiency from sustained high-dose zinc, and significant interference with laboratory assays from high-dose biotin. Acute zinc overdose can cause vomiting, abdominal pain, and dehydration. Suspected overdose requires medical assessment, including a review of relevant laboratory values.

If you miss a dose, take it as soon as you remember on the same day. If it is close to the next dose, skip the missed dose and continue. Do not double the dose.
