Age-Related Cognitive Decline
- Reliable and relatively consistent scientific data showing a substantial health benefit.
- Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
- For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by some in the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
| Supplement | Amount | Why |
|---|---|---|
Acetyl-L-Carnitine | 1,500 mg daily |  [3 stars] Several clinical trials suggest that this supplement delays onset of ARCD and improves overall cognitive function in the elderly |
Ginkgo | 120 to 160 mg daily | [3 stars] Most, but not all, clinical trials have found this herb to be a safe and effective treatment for ARCD.
|
Bacopa | Refer to label instructions |  [2 stars] Animal studies have found this Ayurvedic herb enhances several aspects of mental function and learning ability, and there is some preliminary research that it improves mental function in humans. |
Folic Acid | 800 mcg per day | [2 stars] Folic acid has been shown to slow the rate of cognitive decline in people with high homocysteine levels and in elderly people. |
Huperzia | 100 to 150 mcg two to three times per day | [2 stars] Huperzine A, an extract from a Chinese medicinal herb, has been found to improve cognitive function in seniors with memory disorders.
|
Melatonin | Refer to label instructions | [2 stars] Cognitive function is linked to adequate sleep and normal sleep-wake cycles, which are partially regulated by the hormone melatonin. The long-term effects of melatonin are unknown, use under a doctor’s supervision. |
Phosphatidylserine | 300 mg daily of bovine-derived supplement | [2 stars] Bovine-derived PS (phosphatidylserine) has been shown to improve memory, cognition, and mood in the elderly. To date, most evidence suggests that soy-derived PS is not effective for ARCD.
|
Pine Bark Extract (Pycnogenol) | 150 mg per day | [2 stars] A study of healthy senior people reported that supplementing daily with Pycnogenol improved some measures of memory after three months, compared with a group taking a placebo.
|
Selenium | Refer to label instructions | [2 stars] In a preliminary trial of individuals with mild cognitive impairment and low blood levels of selenium, the improvement in measures of cognitive function was significantly greater in the group eating Brazil nuts than in the control group. |
Vinpocetine | 30 to 60 mg daily | [2 stars] Vinpocetine has been shown to improve dementia symptoms in patients with various brain diseases. |
Vitamin B6 | 20 mg daily | [2 stars] There is evidence that supplementing with vitamin B6 (pyridoxine) may improve memory performance, especially in people who are deficient. |
Vitamin B6, Vitamin B12, and Folic Acid (For women with low dietary intake ) | Refer to label instructions | [2 stars] In women with cardiovascular disease or related risk factors and low dietary intake of folic acid, vitamin B6, and vitamin B12, supplementing with a combination of these nutrients may protect against age-related cognitive decline. |
Vitamin C | Refer to label instructions | [2 stars] Use of vitamin C, alone or with vitamin E, has been associated with better cognitive function and a reduced risk of certain forms of dementia (not including Alzheimer’s disease). |
Astaxanthin | Refer to label instructions |  [1 star] Some, though not all, research has found astaxanthin might protect the brain from age-related oxidative damage. |
Beta-Carotene | 50 mg every other day | [1 star] In one study, long-term beta-carotene supplementation slowed the loss of cognitive function in middle-aged healthy males.
|
Vitamin E | Refer to label instructions | [1 star] Use of vitamin E, alone or with vitamin C, has been associated with better cognitive function and a reduced risk of certain forms of dementia (but not Alzheimer’s disease). |
