Memory-boosting herb works in just 7 days!

More than a dozen studies prove that the right supplement can rev your focus, concentration and memory and keep your brain young while improving your health in other ways, too! Try:

1 Tocotrienols . . . if your cholesterol won’t drop

Tocotrienols—members of the vitamin E family— nourish and energize neurons, helping you feel clear-headed and sharper in three weeks if you take 50 mg. daily, researchers say.

Bonus! These brain-boosting nutrients can also lower your total cholesterol level 30%, reports the journal Atherosclerosis, by switching on liver enzymes that break down excess blood fats.

Important: Always check with your doctor before starting a new supplement.

2 Vitamin B-12 . . . if you tend to be blue

Tufts University researchers estimate that up to 40% of us are struggling with a B-12 shortfall right now and don’t know it! Fortunately, symptoms of a B-12 deficiency—brain fog, memory lapses and blue moods— disappear in as little as one month if you supplement with 1,000 mcg. daily. B-12 nourishes your nervous system, hippocampus and pineal gland, all of which must be in top form to keep your memory sharp and your moods on an even keel, says C.W. Randolph Jr., M.D., of Jacksonville, Florida’s Ageless & Wellness Medical Center.

3 Huperzine A ... if you always feel tired

A daily 100-mcg. dose of the Chinese herb huperzine A sharpens memory and focus for up to 55% of women who try it, reports the journal Pure and Applied

Chemistry. Huperzine A blocks the breakdown of acetylcholine, a compound your neurons need to communicate quickly and easily, says study coauthor Don Bai, PH.D.

Bonus! Huperzine A also helps heart and muscle cells function at their peak, revving your energy and stamina in as little as 30 days, Chinese research reveals.

4 Ginkgo biloba . . . if you’re often anxious

This popular Asian remedy for menopausal brain fog boosts focus, concentration and memory 52% in one week, British studies show. That’s because ginkgo relaxes and opens arteries, increasing the flow of oxygen- and nutrient-rich blood to hardworking brain nerves.

Bonus! The study-proven dose—180 mg. to 240 mg. daily— also tamps down your adrenal glands’ production of stress hormones, cutting feelings of edginess and anxiety as much as 79%.
