The recorded teaspoon serving provides 1,100 mg total omega-3s, including 460 mg EPA and 500 mg DHA, from Norwegian cod-liver oil. The liquid also contains vitamins A and D; compare those amounts with other supplements. IFOS and IGEN certification are reported in the seller record.

Thorne Pyridoxal 5'-Phosphate
THORNEACOG (Obstet Gynecol 2018 Committee Opinion 189) recommends pyridoxine as first-line for NVP. The Matthews et al. 2010 Cochrane review (PMID 20824863) concluded vitamin B6 reduces NVP severity versus placebo. Thorne's P5P is the pre-activated form (pyridoxal-5'-phosphate) — bypasses hepatic conversion and reaches therapeutic levels faster. NSF Certified for Sport is the highest third-party testing tier available for supplements. One capsule every 8 hours totals 99mg P5P per day, approximately equivalent to 75mg pyridoxine — top of ACOG's 30-75mg/day range.

Vitamin D3 + K2 (5000 IU)
Sports ResearchThis Sports Research variant provides 5000 IU vitamin D3 plus 100 mcg vitamin K2 MK-7 per softgel. The current package contains 60 servings. Vitamin D dose, capsule or gummy format and package count distinguish the otherwise similar variants.

Ultimate Omega, Lemon Flavor - 90 Soft Gels - 1280 mg Omega-3 - High-Potency Omega-3
Nordic NaturalsNordic Naturals Ultimate Omega is the category benchmark — 58,000+ Amazon reviews averaging 4.7 stars, molecularly distilled, IFOS-certified, and standardized to 650mg EPA + 450mg DHA per serving. Widely recommended by functional-medicine practitioners.

Thorne Zinc Picolinate supplies 30 mg elemental zinc per capsule in a 60 capsule bottle. The current listing reports NSF Contents Certified, not NSF Certified for Sport.

Antarctic Krill Oil 1000mg
Sports ResearchThis is Sports Research Superba 2 Antarctic krill oil, recorded as 1000 mg oil with 136 mg EPA and 60 mg DHA per serving. Total krill-oil mass should not be compared directly with the EPA + DHA amount in fish-oil products.

Methyl B-12 1000mcg
Jarrow FormulasThe recorded product contains 1,000 mcg vitamin B12 as methylcobalamin in each lemon-flavored chewable tablet, with 100 servings per bottle. Chewable format is a preference; NIH ODS reports no established efficacy advantage for sublingual over oral B12.

Thorne Quercetin Phytosome lists 250 mg phytosome ingredient per capsule, with 60 capsules. The phospholipid complex differs from plain quercetin; phytosome mass is not automatically an equal mass of pure quercetin.

MacuHealth Plus+
MacuhealthMacuHealth Plus+ combines three carotenoids with vitamins C and E, zinc and copper. The manufacturer lists 10 mg lutein, 10 mg meso-zeaxanthin and 2 mg zeaxanthin in the four-softgel daily serving. The 360-softgel variant provides 90 servings.

Micronized Creatine Monohydrate Powder
Optimum NutritionThe recorded product provides 5 g micronized creatine monohydrate per serving and 120 servings per container. The seller reports participation in Informed Choice. The supplied current evidence does not establish Creapure sourcing or a 99.99% purity result.

Collagen Peptides Advanced Unflavored 9.33 oz
Vital ProteinsVital Proteins Collagen Peptides Advanced is the unflavored 9.33 oz variant with 12 listed servings. The current formulation includes bovine collagen, vitamin C and hyaluronic acid; it should not be confused with a plain collagen-only variant.

Brain Octane C8 MCT Oil
BulletproofThe recorded 16 oz liquid contains C8 MCT oil derived from coconut. Its C8-only composition distinguishes it from mixed MCT oils. The seller advises starting with a smaller amount to assess digestive tolerance; ketone production does not by itself prove cognitive or weight-loss benefits.

Lion's Mane
Real MushroomsThe manufacturer identifies an organic lion’s-mane fruiting-body extract made using hot water and reports more than 30% beta-glucans verified by third-party testing. The 120-capsule variant supplies 60 two-capsule servings of 1,000 mg. Beta-glucan content characterizes the extract; it does not prove a cognitive outcome.

Organic Flaxseed Oil Liquid 16oz
Barlean'sThe recorded tablespoon serving supplies 7,640 mg ALA from cold-pressed flaxseed oil. The liquid can be added to food and allows portion measurement without softgels. ALA is a different omega-3 from the EPA and DHA listed on fish-oil products, so compare like nutrients and serving sizes.

QH-Absorb Ubiquinol 100mg
Jarrow FormulasThis 120-softgel variant lists 100 mg ubiquinol per softgel in the QH-Absorb formulation. The softgel amount and formulation identify the product; higher blood CoQ10 levels do not by themselves establish a clinical benefit. The recorded directions allow different daily frequencies, so serving count differs from day supply.

Ashwagandha 300mg
Jarrow FormulasThe recorded formula uses KSM-66 ashwagandha root extract at 300 mg per capsule. The 120-capsule bottle contains 120 one-capsule servings, or 60 days at the recorded twice-daily directions. A branded extract and studied dose do not guarantee a cortisol or stress benefit for an individual.

Theanine 200mg
Jarrow FormulasThe recorded 60-capsule product is described as a 200 mg L-theanine formula in the seller features. The seller title also includes a conflicting 100 mg phrase, so confirm the current label before purchase. The available evidence does not establish a Suntheanine-branded ingredient.

The recorded 180-softgel variant contains 90 two-softgel servings. Each serving lists 2,100 mg total omega-3s, including 1,450 mg EPA and 550 mg DHA. Total omega-3s and combined EPA+DHA are different figures. Prescription purified-EPA trial results should not be attributed to this mixed fish-oil supplement.

Gelatinized Black Maca Capsules
The Maca TeamThe only single-color black maca in our lineup — sourced directly from Junín, Peru at 14,000 feet elevation. Gelatinized for easy digestion and concentrated potency. USDA Organic certified. The Maca Team specializes exclusively in maca, ensuring deep supply chain expertise. Black maca is the rarest (only 15% of harvest) with the strongest research for energy and libido support.

Super Berberine + Wild Bitter Melon
Peak PerformanceCombines berberine HCl with wild bitter melon extract for dual-action metabolic support. Bitter melon has its own clinical evidence for glucose metabolism, creating a synergistic formula that targets multiple pathways.

Thorne Basic Nutrients 2/Day
THORNENSF Certified for Sport — the gold standard in third-party testing, trusted by professional athletes and physicians. Uses active vitamin forms including 5-MTHF (methylfolate), methylcobalamin (B12), and chelated minerals for superior absorption. Two-capsule daily dose is convenient and well-tolerated.

Doctor's Best Saw Palmetto with Euromed
Doctor's BESTUses Euromed's branded saw palmetto extract — produced in Spain using supercritical CO2 extraction for maximum purity and fatty acid concentration. Euromed is one of the most clinically referenced saw palmetto extract suppliers. Full 320mg clinical dose in an oil-based softgel.

Longevity NMN Pro 500
ProHealthProHealth is one of the most established longevity supplement brands, and their NMN Pro uses zymeNMN (enzymatically produced NMN) with publicly available third-party Certificates of Analysis. The enteric coating protects NMN from stomach acid degradation, potentially improving absorption. At 500mg per capsule, it matches the dose used in key clinical trials.

Triple Strength Omega-3
Sports ResearchThis Sports Research Triple Strength Omega-3 variant supplies 1250 mg fish oil with 1040 mg total omega-3s, including 690 mg EPA and 260 mg DHA per softgel. The 90-count package therefore contains 950 mg combined EPA + DHA per softgel, not 1040 mg combined EPA + DHA.
