Analysis

The formula supplies 120 mg rhodiola and 67 mg L-theanine, both below stronger standalone amounts. Rhodiola lacks active-marker standardization.

5-HTP is present at 33 mg, while a 250 mg Relora proprietary blend hides its magnolia and phellodendron contributions if those are included. Vitamin D3 adds a small nutritional component.

The blend may fit mild mood-and-focus support, but it is not a strong energy formula. Serotonin-related interaction risk makes medication review more important than its convenient 90-serving supply.

Who is it for
  • Adults not using serotonin-raising medicines
  • Users seeking mild mood and calm-focus support
  • People comfortable with a proprietary botanical blend
Best for
  • Mood-oriented routines after medication review
  • Mild calm focus
  • Users who value a 90-serving package

Pros

  • Includes 5-HTP, theanine, and rhodiola
  • Ninety servings
  • One-capsule-style convenience
  • Adds vitamin D3

Cons

  • Rhodiola and theanine are modest
  • Rhodiola is unstandardized
  • Relora blend is proprietary
  • Limited direct energy support

Warnings

  • Do not combine 5-HTP with SSRIs, SNRIs, MAO inhibitors, triptans, or other serotonin-raising medicines without professional direction
  • 5-HTP may cause nausea or drowsiness
  • Rhodiola may feel stimulating while theanine and 5-HTP may feel calming, making individual timing less predictable

Nutrient quality

56 Moderate impact

The visible actives offer several relevant mood-support pathways. Modest doses and a large hidden blend prevent a confident judgment of formula strength.

.

Ingredient transparency

43 Lower impact

Visible active amounts are listed, but the proprietary blend hides key components. Blend opacity, incomplete directions, and missing inactive ingredients substantially reduce clarity.

.

Customer satisfaction

65 Moderate impact

The supplied average rating is comparatively mixed. An exceptionally large rating base makes the average highly dependable, but no detailed experience evidence was supplied.

.

Value for money

58 Moderate impact

Serving economics are reasonable. Formula limitations keep practical value moderate.

C+ Goal FitC- Strength of SupportC CoverageB Formula Quality
Vitamin D · 6.68 mcgTheanine · 67 mg

Rhodiola and L-theanine may support mental performance during stress, while 5-HTP and Relora mainly target mood and tension. The formula is better aligned with calmness and stress resilience than memory formation or broad cognitive maintenance.

Theanine and rhodiola amounts are individually stated, but rhodiola lacks species and active-marker standardization and the Relora blend hides its components. The 5-HTP can raise serotonin-related risk when combined with SSRIs, SNRIs, MAO inhibitors, or triptan medicines.

L-theanine and rhodiola may support calm attention and mental stamina under stress. The modest amounts and unstandardized rhodiola make the focus benefit less predictable.

5-HTP and the Relora blend shift the formula toward mood and relaxation rather than clear daytime alertness. 5-HTP can interact with SSRIs, MAO inhibitors, triptans, and other serotonin-raising medicines, increasing the risk of excessive serotonin effects.

Vitamin D · 6.68 mcg

Stress-resilience support from rhodiola may help fatigue, but the formula is oriented more toward mood and calm than direct energy production. L-theanine and 5-HTP may further favor relaxation rather than alertness for some users.

The rhodiola amount is disclosed, yet its species and active-marker standardization are missing, and the Relora blend hides component amounts. The 33 mg of 5-HTP can raise serotonin-related risk when combined with serotonergic medicines such as SSRIs or MAO inhibitors.

B+ Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyD+ Value

Clearly identified L-theanine provides a mild amount in a broad mood-support blend. The active dose is disclosed, but the generic source lacks a purity standard and the Relora blend hides its component amounts. Added 5-HTP improves formula value, though it may interact with serotonergic medicines and raise serotonin-related risks.

F Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyF Value

The measured root extract fits a lower blend-oriented amount, but its species and active-marker profile are not disclosed. Clear separation from the proprietary blend supports dose transparency. A moderate serving cost does not translate into verified Rhodiola value without standardization.

5-HTP (Griffonia simplicifolia) · 33 mg OverallScore40
C+ Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

Griffonia simplicifolia gives the 5-HTP a natural source, although its standardization is not disclosed. The amount is below a standard starting dose but is paired with L-theanine, Relora, and rhodiola in a purposeful mood blend. High 5-HTP-specific cost and missing serotonin-medication warning information are the main weaknesses.

83 Performance

Pure Energy

Swanson
Caffeine, standardized rhodiola, and 160 mg theanine create a concise daytime energy formula with fully stated amounts. It omits 5-HTP and may worsen anxiety or sleep, but it avoids the hidden Relora blend.
79 Performance

Cortisol Calm

Pure Encapsulations
Standardized ashwagandha, rhodiola, magnolia, and theanine create a focused stress formula with mostly clear doses. It omits 5-HTP and costs more, but transparency and adaptogen quality are substantially stronger.
73 Performance

Sunny Mood with 5-HTP

Irwin Naturals
A standard 5-HTP amount anchors a mood formula with rhodiola, theanine, passionflower, saffron, magnesium, and vitamin D3. Supporting doses are modest, but individual ingredients are more visible than the original proprietary blend.
87 Budget

Sleep Regimen 3-in-1

NOW
A much lower serving cost provides fully disclosed theanine, 5-HTP, and melatonin without a proprietary blend. It is sleep-focused rather than daytime mood support, and 5-HTP still carries serotonin-interaction risk.
69 Budget

Sleep Support

Bluebonnet Targeted Choice
It is not strictly cheaper per serving, but it is the nearest-cost eligible alternative with theanine and 5-HTP. Valerian, tart cherry, passionflower, and chamomile shift the purpose toward sleep, while botanical standards remain incomplete.
82 Budget

Tranquil Sleep

Natural Factors Stress-Relax
It is not cheaper, but branded Suntheanine, melatonin, and a modest 5-HTP amount provide a much clearer formula. Rhodiola is absent and the purpose shifts to sleep, while serotonergic medicine interactions remain relevant.
68 Value

Revitalizing Sleep Formula

Nature's Way
Clearly disclosed theanine, 5-HTP, valerian, passionflower, hops, and lemon balm provide far greater dose depth. The serving cost is much higher and sedation plus serotonin-interaction risks are stronger, so value applies only to users seeking a potent sleep formula.
80 Value

Tranquil Sleep

Natural Factors Stress-Relax
A long supply of branded Suntheanine, melatonin, and modest 5-HTP provides clear recurring value without a proprietary blend. Rhodiola is absent and the formula is sleep-specific, while 5-HTP interactions remain relevant.
61 Value

Double Potency 5-HTP Extra

Irwin Naturals
Meaningful 5-HTP and theanine amounts plus vitamin D, magnesium, lemon balm, and saffron provide more active depth. The serving costs more, fish oil lacks separate EPA and DHA amounts, and several supporting ingredients remain poorly characterized.
