What is the recommended daily dose of Sleep Cycle?

The recommended daily dose of Sleep Cycle is 1-2 capsules, 1 time per day, 1 hour before bedtime.

How much Sleep Cycle can I safely take in a day?

You do not need to take more than 2 capsules in a day to gain the full effectiveness of the Sleep Cycle supplement.

How do I know Sleep Cycle is working for me?

Sleep Cycle is a Tango Advanced Nutrition product that should make a change for you in how you sleep. It should promote your sleep health so that you sleep more deeply and wake up fully rested.

You should expect improvements to occur quickly as many of our customers report dramatic improvement in the first few days of use. The change should be very noticeable. Instead of saying to yourself, “I think this might be helping me”, you really should be able to say, “Wow, I feel a lot better.”

Usually, very clear results show up in the first month of use for most people.

Do I have to take Sleep Cycle forever?

Everybody has a different set of circumstances that will determine how their sleep will be promoted when using Sleep Cycle. Your response to the supplement will be determined by your individual health circumstances. Issues with sleep may be long-standing over many years. This may determine how soon you notice positive changes and how long you may need or wish to take the formula.

However, the formula is strong enough so that men and women who will get benefits should expect them in the first month of use.

When positive changes in sleep health occur, you can lower your dose to one capsule per night and expect to see continued benefits. The reason for this is that, as with all true health-promoting supplements, Sleep Cycle provides restorative results.

When should I take Sleep Cycle?

The most important consideration in taking Sleep Cycle is to use it daily and consistently. You should take Sleep Cycle about one hour before bedtime.

Can I take Sleep Cycle with other supplements?

Yes, you can take Sleep Cycle with and at the same time as you take other dietary supplements.

I take over-the-counter/prescriptive medicines for better sleep. Can I take Sleep Cycle with them?

You can take Sleep Cycle while you are using other products for your sleep or any other condition. However, you should always take Sleep Cycle or any other supplement at least 2 hours away from any medication to reduce any possible risk of interaction.

If you have any questions about using Sleep Cycle or any other supplement while you are using medications of any type, ask your doctor or pharmacist for advice.

Can I combine Sleep Cycle with some of your other products like Vital Cell?

Yes, you can take Sleep Cycle with Vital Cell or other Tango supplements. Many people find that the addition of Vital Cell promotes their results when taking Sleep Cycle.

You can also call one of our product specialists if you have questions about how best to combine our formulas. The toll-free number for product questions is 1-866-778-2646, ext. 2.

Can a woman take Sleep Cycle if she is pregnant or nursing?

No, we do not recommend that a woman take Sleep Cycle if she is pregnant or nursing. This is not because Sleep Cycle is unsafe but because there have been no safety studies performed on the ingredients in Sleep Cycle for pregnancy and nursing.

Can children take Sleep Cycle?

Sleep Cycle is not recommended for people under the age of 18.

Can I give Sleep Cycle to my pet (cat, dog, or horse)?

We do not recommend that you give Sleep Cycle to your pet as it is not suitable for common pet nutritional concerns.

Is Sleep Cycle tested for contaminants that could harm my health?

Yes, we regularly test batches of our formulas to make sure they meet strict quality control guidelines recommended by government regulatory agencies.

Are there any side effects from taking Sleep Cycle?

Sleep Cycle does not cause drowsiness or make a person sleepy. It also does not contain any stimulants that might cause jitteriness or lack of sleep.

What do I do if I think taking Sleep Cycle is causing me discomfort?

The most common discomforts experienced by a tiny percentage of people when taking any vitamin, mineral, or herbal formula are digestive upset or very mild allergic reactions such as skin itching or irritability.

These minor discomforts usually disappear by taking a lower dose or by taking the supplement with meals.

If you should experience discomfort when taking Sleep Cycle and it does not go away with these suggestions, then discontinue use and contact our product specialist for further recommendations at 1-866-778-2646, ext 2. If we cannot determine a way for you to continue use of the product to gain its benefits, then we will arrange for a full refund for you.


Directions: As a dietary supplement, take two capsules 30 to 60 minutes before retiring.

Not recommended for pregnant or nursing women.

    It helps

    SleepCycle makes me feel a little bit relaxed and a little bit sleepy. I fall asleep fairly quickly, without a struggle. And I sleep slightly longer, by a half-hour or so. And I feel more relaxed during the following day, without feeling groggy. It seems to help. I’ll keep using it as long as it continues to help.

    This is a great herbal supplement! I received a free sample and gave it to my husband, who sometimes has trouble winding down and sleeping in the evening. He said that it really helped him feel relaxed and fall asleep faster.

    Works great I am now getting a good restful sleep instead of waking up and staying awake for hours. If I wake up and don’t go back to sleep I take a Sleep Cycle and go back to sleep within a half hour.

    I tried your sleep cycle sample according to the directions and did not find that it helped me fall asleep any quicker than if I had taken nothing.
