Study Notes

Red Yeast Rice

Red yeast rice products can lower total cholesterol by up to 23% and LDL cholesterol by up to 34% when taken 1-5 grams daily for up to 24 weeks
Red yeast rice products that contain statins are considered illegal, unapproved drugs by the FDA
The amount of monacolin K (lovastatin) in red yeast rice products is not always clearly stated on the label
Some red yeast rice products contain little or no statins, but many still contain significant concentrations
Some products can contain up to 5 mg of statins per tablet
It is not known whether red yeast rice products that contain a lower concentration of statins can significantly reduce cholesterol levels in patients with hyperlipidemia

Dosing

Labels on red yeast rice supplements usually only state the amount of red yeast rice, not the amounts of monacolin K or other monacolins
A study of 28 supplements found that monacolin K content ranged from 0.09–5.48 mg per 1200 mg of red yeast rice
Typical dose of red yeast rice is 1.2.- 2.4 gram daily in 2 divided doses (600 mg po bid)

Coenzyme Q10

Also referred to as ubiquinone
Fat-soluble antioxidant and endogenously produced
A rate-limiting cofactor in mitochondrial adenosine triphosphate (ATP) formation
CoQ10 is involved in many energy production functions and regeneration of other antioxidants
Stabilizes membranes and may have vasodilatory and inotropic effects

Coenzyme Q10 - Uses

Statin-associated adverse effects
General antioxidant in cardiovascular disease
Many more…

Coenzyme Q10 - Dose Range

50-1200 mg/day
Typical dosages studied have been 100 to 200 mg/day

Coenzyme Q10 - Evidence for Efficacy

Statin Intolerance: statins decrease coenzyme Q10 production, possibly leading to muscle pain
Randomized control trials: results conflicting
Genetic differences may contribute to the variable responses to CoQ10 treatment
In general, research is too limited for any conclusions to be drawn in research or conflicting results have been observed with CoQ10 use

Coenzyme Q10 - ACC/AHA Guidelines

ACC/AHA guidelines currently do not recommend initiation of nutritional supplementation (including CoQ10) as treatment in patients with current or previous symptoms of heart failure
Although results suggested an improvement in the primary MACE endpoint at 2 years, the small event numbers, difficulties in patient recruitment, and an unexpectedly large treatment effect with wide confidence intervals limit the interpretability of the results
At this time point, CoQ10 initiation cannot be recommended to patients with heart failure

Coenzyme Q10 - Safety

No serious side effects reported
Possible side effects (100 mg) doses
Take with food to aid absorption

Garlic

The herb Allium sativum, best known for flavoring

Garlic - Uses

Hyperlipidemia
Hypertension

Garlic - How it Works

Produces allicin, the main component of garlic’s odor, and may be responsible for pharmacologic effect
Animal and in vitro studies: hypotensive, hypolipidemic, antiplatelet, antioxidant, and anti- infective properties
Increases levels of the vasodilator hydrogen sulfide, enhances nitric oxide production, and may inhibit angiotensin-converting enzyme

Garlic - Dosing

Fresh bulb : 1/2-1 raw clove daily (2 – 4 grams fresh garlic)
Dried powder: 0.4-1.2 gram/daily (providing 3 to 5 mg allicin/day)
Enteric-coated capsule: 600-900 mg/day to help with “garlic breath”

Garlic - Evidence for Efficacy

Hyperlipidemia
- May reduce total cholesterol and LDL cholesterol levels in people with high levels of these blood lipids
- The effect is small, and it may take more than 8 weeks before noting any improvement
- No improvement in HDL levels or triglycerides
Hypertension
- Garlic supplements may be helpful for high blood pressure, but the evidence is limited

Garlic - Safety

May increase risk of bleeding
Stop prior to surgery or procedures
Common side effects: bad breath, body odor, heartburn/GI upset

Garlic - Drug Interactions

Saquinavir
Anticoagulants
Antiplatelets

Garlic - Who May Consider This product

Patients with mild hypertension
Patients with mild hypercholesterolemia

Garlic - Patient Counseling

Increased risk of bleeding
Enteric-coated preparation may help decrease breath odor
Odorless products may contain less allicin and may be less effective
Garlic should be stopped 10–14 days prior to surgical procedures to avoid excess bleeding

Fish Oil

Group of polyunsaturated fatty acids
- Omega 3
  - Alpha-linolenic acid (ALA)
  - Eicosapentaenoic acid (EPA)
  - Docosahexaenoic acid (DHA)
The human body can convert small amounts of ALA into EPA and DHA, but the main way people increase levels is to consume foods and supplements that contain omega-3s
ALA is found in walnuts and some plant oils, such as flaxseed, soybean, and canola.
EPA and DHA are high in oysters and fatty fish such as salmon, sardines, mackerel, herring, lake trout, and albacore tuna.

Fish Oil - Uses

Decrease triglycerides
Decrease blood pressure
Reduce cognitive decline in older patients
Cardiac health??? Monitor patients taking fish oils and drugs that affect bleeding (e.g., anticoagulants, antiplatelets)

Fish Oil - Considerations

Fish oil is not the same as fish (cod) liver oil
Avoid eating fish with high mercury content

Fish Oil - Who May Consider This Product

Patients with elevated triglycerides or mild hypertension (no cardiovascular disease history)

Fish Oil - Patient Counseling

Discard products with a strong fishy or rancid smell or taste. This may be an indication of spoilage or poor product quality
Take with meals, freezing, or enteric coated may reduce “fish burps”
Take prescription product to minimize toxins
Not all fish oil supplements are the same; must read label
