e-cups, how have you been? Been MIA!
Anyway, I think that buying the multivits is better than just buying a zinc supplement as different vits are good for different things. The one that Siu Ping has mentioned seems quite good as it has L-Arginine and Korean Ginseng. Similar to the vit I got for my hubby from overseas.

Supplements
The following supplements have been shown to increase sperm count and/or motility. Allow 3-4 months for the supplements to work.
•Arginine—Take 4 gr daily. Needed to produce sperm. If the sperm count is below 10 million per ml, arginine probably will not provide any benefit.
•Coenzyme Q10—Take 10 mg daily. Increases sperm count and motility.
•Flaxseed oil—Take 1 tbsp daily. Is a source of essential fatty acids.
•L-carnitine—Take 3-4 grams daily. Required for normal sperm function.
•Multivitamin-mineral—Buy a high-quality product and take one serving size (differs from brand to brand).
•Selenium—Take 200 mcg daily. Improves sperm motility.
•Vitamin B-12—Take 1000 mcg daily. A B-12 deficiency reduces sperm motility and sperm count. Even if no deficiency exists, B-12 supplementation may help men with a sperm count of less than 20 million per milliliter or a motility rate of less than 50%
•Vitamin C—Take 500 mg 2 times daily. Is an antioxidant.
•Vitamin E—Take 400 IUs 2 times daily. Is an antioxidant and improves sperms’ ability to impregnate.
•Zinc—Take 15 mg 2 times daily. Required for a healthy male reproductive system and sperm production.
