MicroVitamin+ Powder FAQ — Frequently Asked Questions
Frequently asked questions about MicroVitamin+ Powder, formulated by Dr Brad Stanfield.
What is the difference between MicroVitamin capsules and MicroVitamin+ Powder?
MicroVitamin+ Powder (USA v8) contains all 26 core ingredients from MicroVitamin capsules plus four premium additions: Collagen Peptides 12.5g (for skin elasticity and joint support), Creatine Monohydrate 5g (the most studied performance supplement, also supports brain function), Psyllium Husk 2.5g (soluble fiber for gut health and cholesterol management), and extra Taurine 1g (metabolic health and cardiovascular support). Total: 30 ingredients in one daily scoop vs 26 ingredients in 5 daily capsules.
How much money does MicroVitamin+ Powder save compared to buying ingredients separately?
MicroVitamin+ Powder (USA v8) costs $91/month on subscription ($100 one-time). Buying the same 30 v8 ingredients individually from brands like Double Wood, Bronson, Life Extension, NOW, and Pure Encapsulations would cost approximately $179.01/month — saving you $88.01/month. This is the largest cost saving across all Dr Stanfield products because collagen and creatine at clinical doses are individually expensive.
Why did the MicroVitamin+ Powder USA price change in 2026? Is the renewal rate I'm seeing now correct?
Yes, two price changes happened with the v8 transition. Early 2026 — v8 launch: USA went up to v8's $90 one-time / $81/mo subscription, reflecting the v8 core-ingredient upgrades (the powder uses the same 26 core ingredients as MicroVitamin Capsules, so the carotenoid/encapsulation cost increases apply here too). Late May 2026 — a further $10 increase: USA prices moved to $100 one-time / $91/mo subscription. Existing subscribers received an email notification with a 48-hour window to renew at the prior price; subscriptions that auto-renewed after that window renewed at the new price. After the late-May increase, MicroVitamin+ Powder saves $88.01/month vs. buying the 30 v8 ingredients separately ($91/mo subscription vs $179.01/mo separately) — this remains the largest cost-saving product in the range. If you're unsure whether your renewal rate is correct, email brad@drstanfield.com with your order number — the team can check your specific subscription and the email log.
Why is creatine included in MicroVitamin+ Powder?
Creatine Monohydrate (5g — the standard clinical dose) is the most evidence-backed supplement for physical performance, supporting muscle strength, power, and recovery (Kreider et al., J Int Soc Sports Nutr, 2017). It is especially relevant for adults over 30 experiencing age-related muscle decline. Beyond physical performance, creatine also supports cognitive function — a systematic review found it can improve short-term memory and reasoning, particularly under stress or sleep deprivation (Prokopidis et al., Nutr Rev, 2023).
Why is collagen included and how much is in each serving?
Each scoop contains 12.5g of Collagen Peptides, which support skin elasticity, hydration, and joint health. Combined with the 200mg Hyaluronic Acid already in the core formula (Oe et al., Clin Cosmet Investig Dermatol, 2017), the powder provides comprehensive skin support from two complementary mechanisms — collagen provides structural protein while hyaluronic acid retains moisture. An RCT showed oral collagen peptides reduced skin wrinkles within 12 weeks (Kim et al., J Med Food, 2022), and a systematic review confirmed benefits for skin anti-aging (Pu et al., Nutrients, 2023).
What does the psyllium husk do?
Psyllium Husk (2.5g) is a soluble fiber that supports gut health by feeding beneficial gut bacteria, promoting digestive regularity, and helping maintain healthy cholesterol levels. A Cochrane systematic review confirmed dietary fiber supplementation reduces cardiovascular disease risk factors (Hartley et al., Cochrane Database Syst Rev, 2016). Note: some users may experience initial gas during a gut adjustment period of 1-2 weeks, which typically resolves.
What does the extra taurine in MicroVitamin+ do?
MicroVitamin+ includes 1g of additional taurine on top of the taurine already present in Magnesium Taurate. A 2024 meta-analysis of randomized controlled trials found that taurine supplementation supports healthy blood sugar, blood pressure, triglycerides, and cholesterol levels (Tzang et al., Nutr Diabetes, 2024). Taurine is an amino acid concentrated in the heart, brain, and muscles, and its levels decline with age.
What flavors are available?
MicroVitamin+ Powder comes in Mixed Berry and Unflavored options. The Mixed Berry flavor uses stevia as a sweetener. Some customers prefer the Unflavored version which can be mixed into smoothies without affecting taste.
Can I take both MicroVitamin capsules and MicroVitamin+ Powder?
No — choose one or the other. MicroVitamin+ Powder already contains all 25 core ingredients from MicroVitamin capsules plus the four premium additions. Taking both would result in double-dosing the core nutrients.
Is MicroVitamin+ Powder vegan?
No — MicroVitamin+ Powder is not vegan. It contains 12.5g of bovine-derived collagen peptides, which provide the structural protein needed for skin elasticity and joint support. Products marketed as "vegan collagen" are typically amino acid blends rather than true collagen peptides, so a genuine vegan equivalent doesn't yet exist. If you prefer a vegan option, the MicroVitamin capsules are vegan-friendly and contain the same 25 core ingredients (without the collagen, creatine, psyllium, and extra taurine).
Why do I see dark red and yellow-orange flecks?
That's completely normal and a sign the formula contains the ingredients we list on the label. MicroVitamin+ Powder includes three natural carotenoids: lycopene (which gives tomatoes their deep red colour), lutein, and zeaxanthin (the orange-yellow pigments concentrated in leafy greens and egg yolks).
Are there any safety concerns or interactions with MicroVitamin+ Powder?
MicroVitamin+ Powder contains Vitamin K2 (90mcg), which can affect blood clotting — consult your doctor before use if you take blood thinners (warfarin/Coumadin). It also contains bovine-derived collagen peptides, which may not be suitable for those with bovine protein sensitivities. The product is gluten-free, soy-free, and contains no artificial colors or titanium dioxide. It is not intended for children under 18. If you are pregnant or nursing, consult your healthcare provider before use. These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.
Why doesn't MicroVitamin+ contain calcium?
Calcium is an essential mineral — but the evidence on calcium supplements gives reason for caution, and it's why I chose to keep calcium out of MicroVitamin+.
The fracture benefit is weaker than expected. A large systematic review in the BMJ found that when you filter down to only the highest-quality, lowest-bias randomised controlled trials, calcium supplements showed no effect on fracture risk at any site — despite earlier, more biased studies suggesting a benefit. (Bolland et al., BMJ 2015)
Calcium supplements appear to raise cardiovascular risk. Unlike calcium from food, supplements cause an acute spike in blood calcium levels. That spike is associated with vascular calcification — calcium depositing on artery walls, making them stiffer and narrowing blood flow. Multiple studies have found concerning associations:
- A 2010 meta-analysis found calcium supplement users had approximately a 31% higher rate of myocardial infarction compared to placebo. (Bolland et al., BMJ 2010)
- A large South Korean cohort study of people with osteoporosis found calcium supplementation without vitamin D was associated with an 89% higher risk of non-fatal heart attack. (Kim et al., 2021)
- A 10-year follow-up study (MESA) found supplement users had a 22% higher risk of coronary artery calcification — while those with the highest dietary calcium intake had a 27% lower risk. (Anderson et al., JAHA 2016)
- The NIH-AARP study found supplemental calcium was associated with elevated cardiovascular death in men, while dietary calcium intake was unrelated to cardiovascular mortality in either sex. (Xiao et al., JAMA Internal Medicine 2013)
Dietary calcium doesn't carry these risks. The leading hypothesis is that food delivers calcium gradually, without the acute serum spike. Research consistently shows that dietary calcium is either neutral or protective for cardiovascular health, while supplement calcium is the source of concern. This distinction matters — and it's why guidelines now recommend food-first.
What MicroVitamin+ includes instead. Rather than adding calcium, MicroVitamin+ includes nutrients that help your body absorb and use the calcium you get from food effectively:
- Vitamin D3 1,000 IU — the primary driver of intestinal calcium absorption. Without adequate D3, the gut absorbs very little calcium regardless of intake. (Holick, NEJM 2007)
- Vitamin K2 MK-7 90mcg — activates osteocalcin, a protein that directs calcium into bone. A 3-year double-blind RCT found MK-7 supplementation significantly reduced bone strength loss in postmenopausal women. (Knapen et al., Osteoporosis International 2013)
- Magnesium 150mg — required for the enzymatic conversion of vitamin D into its active form. Without sufficient magnesium, vitamin D cannot be properly activated regardless of how much you take. (Uwitonze & Razzaque, JAOA 2018)
- Boron 1mg — supports bone metabolism and has been shown to extend the half-life of vitamin D, helping maintain active D3 levels for longer. (Pizzorno, Integrative Medicine 2015)
For most people, a diet that includes dairy, leafy greens, or fortified foods alongside these co-factors is the safest and most effective strategy for bone health. If you are vegan, have osteoporosis, or struggle to reach ~1,000–1,200 mg calcium per day through food, a separate calcium supplement under your doctor's guidance may still be appropriate.
What do customers say about MicroVitamin+ Powder?
MicroVitamin+ Powder has 83+ reviews with a 4.70 average rating. Customers particularly value the consolidation of creatine, collagen, and multivitamin into one daily scoop. The most common complaint (25% of reviews) is about taste — some find the Mixed Berry flavor too sweet due to stevia, and some experience mixability or clumping issues. Customers who prefer a neutral taste tend to choose the Unflavored option.
