Papers available

There have been no papers published on Tinnitus Guard as a supplement, but there have been >50 published on its component parts. However, the only studies considering tinnitus for these were for niacin (nicotinamide).

Conclusions drawn

Studies suggest hibiscus has antibacterial, anti-oxidant, diuretic and anti-hypertensive effects. It is regarded as safe [5].

Hawthorn extracts have been used in the treatment of heart problems, including heart failure as it increases coronary blood flow. It can lower blood pressure.[6] Although it may interact with some medications, it is regarded as safe.[7]

Olive leaf extract has claimed antioxidant and antiviral activity but studies do not support its use for any indication. It is likely to be safe.[8]

Niacin (vitamin B3) can improve cholesterol levels at high doses. As nicotinamide, there is evidence that it is not effective.[9] Side effects are common.[10]

Vitamin C is important for bones, connective tissue, muscles, blood vessels. It helps the body absorb iron, needed for red blood cell production. Side effects are rare.[11]

Vitamin B6 is used to treat a type of anaemia (lack of red blood cells). High levels of supplementation or prolonged use can cause severe nerve damage.[12]

Folic acid is needed to make DNA and other genetic material. Side effects are rare.[13]

Vitamin B12 helps keep the body’s nerves and blood cells healthy.

It is not certain whether garlic is effective in treating any medical condition. It is safe as a foodstuff but unregulated as a supplement.

Buchu leaves have traditionally been used as a diuretic and for kidney or urinary tract infections. It can cause stomach and kidney irritation and can be an abortive.[14]

Uva ursi is also used for problems with the urinary tract or to help with hard stools. Side effects include tinnitus.[15]

It has been suggested that juniper berries have potential antimicrobial, antioxidant and neuroprotective effects but no clinical data exists to support the use of juniper for any indication. It should not be used by someone who is pregnant/breastfeeding.[16]

Green tea has been used as an aid in treating high cholesterol and maintaining mental alertness[17] but it uncertain whether it is effective in treating any medical condition. Green tea supplements can be toxic in large doses.[18]
