FAQ
Frequently asked questions
Are foundation nutrients really enough?+
If consistency is your priority, yes. A multi, D3, omega-3, and magnesium cover most nutritional gaps. The OAK advantage is the flexibility to layer BEAST/TITAN staples when you decide to push.
Which supplements are safe long-term?+
Whey, creatine, multivitamin, fish oil, vitamin D, and magnesium have established long-term safety. The exceptions: high-dose fat-soluble vitamins (A/E) and iron (overload risk).
Same stack as I age?+
From your 40s, layer vitamin D, zinc, and ashwagandha for testosterone maintenance and collagen for joint protection. Think of it as porting in elements of the KEEPER stack.
