Sereniten Plus
Sereniten Plus by Douglas Laboratories is a combination supplement designed to support relaxation, containing Casein Decapeptide at 175 mg, L-Theanine at 50 mg, and Vitamin D3 at 100 IU per vegetarian capsule. This product received an N+ Score of 34, earning an 'F' grade, indicating a poor quality rating. Both Vitamin D3 and L-Theanine are identified as underdosed compared to typical clinical recommendations for their respective benefits. With only 3 total ingredients, the formulation is transparent but lacks sufficient dosages for key active compounds. This product may be considered by individuals seeking minor relaxation support, but those looking for clinically effective doses of L-Theanine or Vitamin D3 may need to explore higher-potency alternatives.
