Sun – For Sun we recommend taking one capsule per day with sufficient water. Since the formula contains the fat-soluble vitamins D3 and K2, Sun is best taken with a meal. The time of day is not important. Renew – For Renew we recommend taking 3 capsules daily with sufficient water. You can decide for yourself whether you would rather take the capsules with a meal or not. However, the effect of L-tryptophan can be increased by taking it on an empty stomach.
