Obtaining SEREDYN

If you question is not listed above, please contact SEREDYN Customer Support.


Will SEREDYN work for me?

Most people who take SEREDYN experience increased relaxation, a sense of well-being, and reduced worry within 30 minutes. The success rate of SEREDYN is high, with as many as 90% of users reporting positive results (in informal, non-scientific user surveys). Please keep in mind, however, that every person is different and SEREDYN's effects for any individual, if any, will vary.

How quickly does SEREDYN take effect?

SEREDYN is designed to work quickly. According to our informal surveys, 69% of SEREDYN users report that, on average, SEREDYN begins working in less than 30 minutes.

How long does a single serving of SEREDYN continue working?

On average, SEREDYN's effects last for 4-6 hours after a single serving (according to informal user surveys). Of course, individual results vary, and some clients report that SEREDYN continues working for eight hours or more.

What's the difference between AMORYN and SEREDYN?

Both SEREDYN and AMORYN can promote relaxation and a positive outlook. But the supplements contain different ingredients that work through different mechanisms. One serving of SEREDYN works quickly (i.e. within 15-60 minutes) to provide a sense of calm and tranquility. Though SEREDYN can be taken every day, it's also effective when taken occasionally "as needed". AMORYN must be taken every day and works gradually over many weeks. Thus, AMORYN is a daily supplement for sustained mood support, and SEREDYN is a fast-acting supplement that can be taken "as needed" to calm quickly. If you're interested in a supplement to help relieve occasional, mild anxiety, then you should order SEREDYN. But if you're also looking to promote a positive mood and support emotional health, consider combining AMORYN and SEREDYN.

Directions for Use

Should I take SEREDYN every day, or only "as needed"?

SEREDYN can be taken either every day or "as needed". For detailed information, read the Dosage and Directions for Use.

How many capsules should I take at once? And how many times per day should I take SEREDYN?

A single capsule is sufficient for most people, but in some cases taking two capsules at once may be more effective. For regular daily use, the recommended amount is one or two capsules up to three times daily. For occasional use, take one or two capsules "as needed". In times of significant fear or stress, you can take three capsules at once if necessary. Do not exceed six capsules in one day. Please see the Dosage and Directions for Use for more information.


Is SEREDYN safe for children?

Children under twelve (12) should not take SEREDYN (or any other supplement) without the supervision of a pediatrician.

Is it safe to take SEREDYN while pregnant or nursing?

Consult your physician before taking SEREDYN while pregnant or nursing.

Will SEREDYN interact with my birth control pills?

None of the ingredients in SEREDYN are known to interact with common forms of birth control pills. If you're taking any prescription medication, consult your physician before taking SEREDYN.

Is it safe to consume alcohol while taking SEREDYN?

Do not consume alcohol until you are familiar with the effects of SEREDYN. In general, consumption of moderate amounts of alcohol is safe while taking SEREDYN. SEREDYN may increase the sedative effects of alcohol, so avoid drinking large quantities of alcohol while taking SEREDYN.

Can I take SEREDYN if I am already taking prescription medications?

Before taking SEREDYN, talk your doctor if you are taking muscle relaxants, sleep or anxiety medicines, pain medicines, seizure medicines, or other medicines that cause drowsiness. SEREDYN may increase the sedative effects of these drugs. Do not take SEREDYN if you are currently taking an MAOI. Consult your doctor before taking SEREDYN if you have a serious or potentially fatal medical condition.

Can I take SEREDYN with other vitamins or nutritional supplements?

Yes, it's safe to take SEREDYN if you are also taking other vitamins or nutritional supplements. Adding GABA and/or Taurine, amino acids that work immediately to promote feelings of relaxation and tranquility, may be worth consideration. If you do not have liver disease and do not take drugs that can damage the liver, consider taking Kava, an effective herbal relaxer, with SEREDYN. (Look for Kava supplements standardized to at least 30% kavalactones.) You may see best results by combining SEREDYN with AMORYN, a daily supplement containing natural ingredients to boost mood and support emotional health.

Does SEREDYN contain: gluten, soy, casein, yeast, or wheat?

No, SEREDYN does not contain: gluten, soy, casein, yeast, or wheat.

Possible Side Effects

Will I experience side effects when taking SEREDYN?

Most people taking SEREDYN report experiencing no side effects (according to non-scientific online surveys of SEREDYN users). And of those users that do report side effects, nearly 4 out of 5 describe them as "mild".

What are the possible side effects?

You are unlikely to experience side effects when taking SEREDYN (based on informal user surveys). When side effects do occur, they tend to be mild and often disappear. The most common side effects reported by SEREDYN users include drowsiness, fatigue, stomach upset, and headache. SEREDYN may increase the effects of sedative drugs or lower blood pressure.

Is SEREDYN addictive or habit-forming?

No, SEREDYN is not habit-forming when taken as directed.
