Analysis

unbranded ashwagandha extract supplies 500 mg in one capsule. The extract amount is substantial, but the label does not provide a withanolide marker or extract ratio despite the standardized wording.

It may support broad stress, mood, sleep, and vitality goals, though actual active strength remains uncertain. One capsule and a low serving cost make the product easy to use.

Missing standardization details weaken comparisons with Sensoril, KSM-66, or clearly marker-labeled extracts. Start with the lowest practical serving and judge tolerance before making it a regular part of the routine.

Who is it for
  • Adults seeking a higher ashwagandha amount
  • Budget-focused users
  • People who do not require branded extract data
Best for
  • Simple daily ashwagandha
  • Broad stress support
  • Low-cost capsule use

Pros

  • Substantial 500 mg extract amount
  • One-capsule serving
  • Low serving cost
  • Focused formula

Cons

  • No withanolide percentage
  • No extract ratio
  • No named branded extract

Warnings

  • Ashwagandha may cause drowsiness or stomach upset; avoid combining it with sedatives until individual effects are known.
  • Avoid ashwagandha during pregnancy, and seek guidance during breastfeeding because safety is not established.
  • Ashwagandha may affect thyroid function and can complicate dosing of thyroid medicines.
  • Stop use and seek care for jaundice, dark urine, or severe fatigue because rare liver injury has been reported with ashwagandha.

Nutrient quality

72 High impact

The extract is unbranded and lacks withanolide standardization, while calcium uses a basic form. A substantial amount is supplied, but missing marker detail and a low-value calcium addition weaken quality.

Ingredient transparency

78 High impact

Ashwagandha and calcium amounts are stated clearly. No proprietary blend hides the listed active doses.

Customer satisfaction

71 High impact

The supplied average is strong, with large response volume. Complaint patterns and purpose-related experiences are not supplied.

Value for money

73 High impact

The asking price is only partly justified by the disclosed formula. Serving value is moderate relative to the formula quality.

Standardized Extract Ashwagandha 500 mg provides 500 mg standardized withanolide ashwagandha and has 1,506 reviews averaging 4.68, indicating strong customer satisfaction. NSF distinguishes facility GMP oversight from finished-product certification, so a current product-specific quality mark should be checked rather than assumed.

NIH notes that ashwagandha can cause drowsiness or stomach upset and may affect thyroid function or interact with medicines, so individual safety fit matters.

Reported customer feedback averages 4.68 out of 5 across 1,506 reviews. An unbranded extract without marker standardization limits ingredient-form confidence; the exact milligram quantity is transparent, but dose alignment is limited or uncertain. Ashwagandha may affect thyroid function and has rare liver-injury reports, so pregnancy, thyroid or liver concerns, and potentially interacting medicines warrant clinician guidance.
